U.S. Seasonal Forecast for Health: November 2022 – January 2023
Regional health forecasts for heat, wildfire, drought, and hurricanes
In the coming months, most of the contiguous U.S. will experience temperatures 0.9 – 3.6 °F (0.5 – 2 °C) warmer than normal. Warming winters can cause earlier and longer allergy seasons, aggravating conditions like allergic asthma. Increasing winter temperatures can also contribute to earlier onset of vector-borne diseases like Lyme disease.
Alaska: Alaska is likely to remain drought-free through the end of January 2023. Normal significant wildland fire potential is also expected.
Northwest: Drought is favored to persist in parts of southern Idaho and Oregon. However, drought improvement and removal is favored in much of the region.
Southwest: Drought is favored to persist in California, Nevada, Utah, and parts of Arizona, New Mexico, and Colorado. However, drought improvement is favored in the northwestern corner of California. Above normal wildland fire* potential is forecast for parts of southern California into November, before returning to normal potential in December.
Hawai’i and Pacific Islands: The Central Pacific is projected to have a below-average hurricane season. Drought improvement and removal is favored in Hawai’i. The Hawai’ian Islands will continue to have above normal wildland fire* potential, especially lee sides, through November before returning to normal potential in December.
Northern Great Plains: Drought is favored to persist or develop in Nebraska. Drought is also favored to persist in parts of Montana, North Dakota, South Dakota, and Wyoming. However, drought improvement and removal is favored in western Montana.
Southern Great Plains: Drought is favored to persist or develop in Kansas, Oklahoma, and Texas. Above normal wildland fire* potential is forecast for much of Oklahoma and Texas into December, before returning to normal potential in January.
Midwest: Drought is favored to persist or develop in Missouri; persist or improve in Minnesota, Illinois, and Kentucky; improve in Michigan, Wisconsin, Indiana, and Ohio; and develop, persist, or improve in Iowa. Above normal wildland fire* potential is likely to continue for southern Missouri through November, before returning to normal in December.
Southeast: The Atlantic basin is forecasted to have an above-average hurricane season with 14 – 20 named storms with winds of 39 mph or higher, with 6 –10 of those possibly becoming hurricanes with winds of 74 mph or higher, and 3 – 5 possibly becoming major hurricanes with winds of 111 mph or higher. Drought is favored to persist or develop in Alabama, Arkansas, Georgia, Louisiana, and Mississippi, and parts of Florida, South Carolina, and Tennessee. Above normal wildland fire* potential is forecast for much of Arkansas, Louisiana, Mississippi, Alabama, and western Tennessee through November, with above normal potential continuing in much of Louisiana and Mississippi into December. Above normal potential is also forecast in western Kentucky during November. The region is forecast to have near normal significant wildland fire* potential during January.
Northeast: Drought improvement and removal is favored along the northeastern seaboard, including in Connecticut, Massachusetts, New Hampshire, New Jersey, and New York.
Caribbean: Puerto Rico is likely to remain drought-free through the end of January 2023. Normal significant wildland fire potential is also expected.
*Smoke from wildfires can impact health hundreds of miles from site of the fire.

Summer 2022 Retrospective
Where Was Heat Abnormally High in 2022?
Figure. Temperature is calculated from NOAA’s nClimGrid-Daily v1-0-0, a 5km gridded dataset aggregated into counties for the contiguous US. For each day between April 1st to September 30th, a county’s temperature in 2022 is compared against its climatological normal from 1991-2020. Temperatures above the 95th percentile are considered abnormally hot for the region.
This map depicts the number of summer days in 2022 (April 1st to September 30th) when a county’s maximum temperature exceeded its 95th percentile, thus indicating an abnormally hot day. Much of the southern great plains, including Texas, Oklahoma, Arkansas, Missouri, Kansas and Nebraska experienced more than a month’s worth of hot temperatures.

Is Heat Related Illness Worse In 2022 Compared to the Last Four Years?
Figure. The CDC National Syndromic Surveillance Program (NSSP) provides daily rates of heat related illness (HRI) by HHS Regions. NSSP is a network comprising CDC representatives, state and local health departments, and academic and private sector health partners jointly collecting and sharing electronic patient encounter data.*
The graphic above compares the rate of HRI per 100,000 emergency department (ED) visits from April to September in 2022 with the rate observed in 2018-2021 for the same months. The average rate of HRI was calculated by HHS regions for April 1– September 30 for 2022 and 2018-2021 separately after quality control filters were applied to allow comparison across years. The average HRI rates in 2022 were higher in 7 out of 10 HHS regions when compared to the average rates in 2018-2021. Particularly noteworthy were the higher rates of HRI in HHS regions 6 and 7 in 2022.
For more information on HHS regions, see list above.
* NSSP includes ED visit data from approximately 72% of non-federal U.S. EDs. Fewer than 50% of facilities in CA, Hawaii, Iowa, Minnesota, and Oklahoma report to NSSP. MO discharge data is incomplete.
Oregon Health Plan Responds to Extreme Heat
The Centers for Medicare & Medicaid Services recently approved a Medicaid 1115 waiver from the Oregon Health Plan to allow coverage of medically necessary air conditioners, heaters, humidifiers, air filtration devices, generators, and refrigeration units when certain requirements are met. Oregon has increasingly struggled with climate change-related health threats. In 2021, record-breaking heat resulted in the loss of over 100 lives (see July Outlook discussion of the Health Impacts During the Heat Dome of 2021). Extreme heat and wildfires have a significant impact on the health and well-being of millions of people in Oregon each year, particularly low-income and historically marginalized groups. To respond to these threats, the Oregon Health Plan is working on establishing a dedicated Medicaid unit to address climate impact on public health. This waiver will allow Oregon to expand its volume and capacity to respond to climate emergencies with cooling and air filtration equipment. The waiver builds on previous state legislation (Senate Bills 1536 and 762), which funded the Oregon Health Authority to provide air conditions and other equipment to Medicaid recipients. During 2022, OHA and its partners identified qualifying individuals who could be at-risk using data like the Oregon Heat Hazard Report. Oregon Health Plan’s goal through its waiver and other activities is to prevent injury, illness and/or death due to the extreme or prolonged heat exposure.
Increasing Assistance for Americans to Cool Their Homes
Figure. The Office of Community Services (OCS) at the Administration for Children and Families implement The Low-Income Home Energy Assistance Program, known as LIHEAP, to mitigate heat stress and ensure households can stay safe and cool in their homes. The above chart illustrates cooling assistance spending from 2015 - 2020 from state LIHEAP grant recipients.
On July 19, 2022, OCS issued updated guidance outlining all the ways grant recipients can use LIHEAP funding to mitigate heat stress. A total of 27 states and the District of Columbia provided cooling assistance benefits in Fiscal Year (FY) 2022; an increase of 4 states compared to FY 2021. Multiple grant recipients implemented cooling programs for the first time in FY 2022 including North Carolina, Washington, and the Pueblo of Laguna Tribe. Additionally, many grant recipients significantly expanded their cooling programs. For example, New York (NY) has historically only provided cooling benefits to households with a medical need for an air conditioner and typically allocates approximately $3-9 million for cooling assistance each year. In FY 2022, NY allocated $23 million for cooling assistance and expanded eligibility to all LIHEAP eligible households, not just those with a medical need. Preliminary FY 2021 data indicates that 23 states and the District of Columbia provided an estimated $564 million for cooling assistance. OCS is committed to continuing to help LIHEAP grant recipients utilize program flexibilities to mitigate heat stress and provide cooling assistance to vulnerable households.
Average Drought Level Across the U.S. in the Past Year
Figure. This map shows the Drought Severity and Coverage Index (DSCI) values for the continuous U.S. from October 1, 2021 - September 30, 2022. The DSCI is an experimental method for converting drought levels from the U.S. Drought Monitor map to a single value for a county.
From October 1, 2021 - September 30, 2022, the majority of the U.S. had some level of abnormal dryness as measured by the DSCI. Possible values of the DSCI are from 0 to 500. Zero means that none of the area is abnormally dry or in drought, and 500 means that all of the area is in D4, exceptional drought. The northwest, southwest, northern great plains, and southern great plains generally had the highest levels of drought. 17 counties had DSCI values in the highest range (>400), meaning they experienced exceptional drought: eight counties in California, four counties in Oregon, two counties in Nevada, two counites in Texas, and one county in Montana. In addition to those states, counties in Oklahoma, New Mexico, and Utah also rank in the top 50 for drought in the past year. Only 61 out of the 3221 counties for which we have measurements had zero dryness or drought. You can explore the full list of counties here.
Wildfire Outlook for November, 2022 – January, 2023
Figure: The National Significant Wildland Fire Potential Outlook identifies areas with above, below, and near normal significant fire potential using the most recent weather, climate, and fuels data available. These outlooks are designed to inform decision makers for proactive wildland fire management.
Year-to-date acres burned for the US is approximately 108% of the 10-year average, with an above average number of fires as well. Above normal significant wildland fire potential is forecast for much of Oklahoma, Texas, the Lower Mississippi Valley, and central Gulf Coast into December. Above normal potential is likely for the western Ohio Valley through the Ozarks into November. The Transverse and Peninsular Ranges of southern California to the coast, areas prone to Santa Ana winds, will have above normal significant potential into November, before returning to normal potential in December. The Hawai’ian Islands will continue to have above normal potential, especially lee sides, through November before returning to normal potential in December. All the US is forecast to have near normal significant fire potential during January.
Wildfires Affect Health in Many Ways
Wildland fire increases the risk for a diverse range of health outcomes from both the fire itself and smoke. For example :
- Due to the nature of their work, firefighters are at risk of developing severe heat-related illness (such as heat stroke) and rhabdomyolysis (muscle breakdown).
- Wildfire can cause burns through contact with flames and hot surfaces as well as chemical and electrical burns.
- Wildfire smoke can lead to disorders including reduced lung function, bronchitis, exacerbation of asthma, and cardiovascular effects like heart failure.
- For pregnant people, smoke exposure may increase the risk of reduced birth weight and preterm birth.
- Wildfire smoke may affect the immune system, potentially leading to increased vulnerability to lung infections like COVID-19.
- Smoke and ash from wildfires can travel downwind and affect air quality hundreds of miles away from the fire.
Real-Time Tracking of Respiratory Outcomes Linked to Wildfire Smoke
Figure. This graph overlays the percentage of Emergency Department (ED) visits due to asthma or reactive airway disease (RAD) in San Mateo County during the 2018 Camp Fire. It uses Morbidity and Mortality Weekly Report weeks, which begin with 1 for the first week of the year. Each red dot indicates an instance where the percent of ED visits due to asthma or RAD is exceptionally high. You can learn more on the CDC’s website.
As wildfires continue to threaten the public’s health across the country, agencies are demonstrating the utility, reliability, and timeliness of syndromic surveillance data for monitoring and characterizing health impacts. During the first two weeks of the 2018 Camp Fire in California, there were higher-than-expected increases in 24-hour particulate matter (PM2.5) concentrations in San Mateo County, which reached unhealthy levels. San Mateo County public health officials monitored for acute respiratory health effects and, in collaboration with the CDC National Syndromic Surveillance Program and the California Department of Public Health, they demonstrated an increase in the weekly percentage of ED visits for asthma or reactive airway disease (RAD) exacerbation, and an increase in the number of visits for smoke exposure or smoke inhalation. Among participating EDs, the county’s safety net hospital had the highest average daily percentage of ED visits for all respiratory syndromes, excluding influenza-like illness and pneumonia.
How does smoke impact firefighter health?
Source: Kathleen M. Navarro, Michael T. Kleinman, Chris E. Mackay, Timothy E. Reinhardt, John R. Balmes, George A. Broyles, Roger D. Ottmar, Luke P. Naher, Joseph W. Domitrovich, Wildland firefighter smoke exposure and risk of lung cancer and cardiovascular disease mortality, Environmental Research, Volume 173, 2019, Pages 462-468, ISSN 0013-9351, https://doi.org/10.1016/j.envres.2019.03.060.
One study funded by the Joint Fire Science Program found that wildland firefighters are at an increased risk for the development of lung cancer (8 percent to 43 percent above the general population) and cardiovascular disease (16 percent to 30 percent above the general population). This risk increases with an increase in career duration and days spent on wildfire incidents (short and long season) each year. The risk of lung cancer steadily rose as career length, while the risk of cardiovascular disease increased sharply for firefighters with 5- to 15-year careers and increased slightly over 20- and 25-year careers. As fire seasons continue to increase in severity and duration, firefighters should reduce exposure to smoke in any way possible.
Wildfire Smoke Can Travel Far Distances
Figure: Example of the AirNow Fire and Smoke Map run by U.S. EPA and the U.S. Forest Service. This screenshot, from September 15, 2020, shows the far distances smoke can travel from the location of wildfires. The map also shows the U.S. Air Quality Index (AQI) from hundreds of air quality monitors and more than 10,000 privately owned air sensors. Green symbols indicate a good AQI; yellow indicates moderate; orange indicates unhealthy for sensitive groups; red indicates unhealthy for everyone; and purple indicates very unhealthy. The flame symbols indicate a large fire incident, and the small yellow spark symbols indicate unverified satellite fire detections.
Wildfire smoke can impact the health of people close to the fire and at distances far from fire impacted areas, depending on meteorological conditions, such as wind speed and direction. As wildfires burn, they generate smoke that is comprised of a mixture of particulate matter (PM) (also referred to as particle pollution) and gaseous pollutants (e.g., carbon monoxide). The pollutant of most concern to public health during a smoke event is fine particulate matter, or PM2.5, because these particles can penetrate deep into your lungs and cause adverse health effects.
Resources to Reduce Health Risks Associated with Wildfire
Exposure to air pollutants in wildfire smoke can irritate the lungs, cause inflammation, alter immune function, and increase susceptibility to respiratory infections, likely including COVID-19.

Protecting Vulnerable Populations from Wildfire Smoke
Image source: https://ww2.arb.ca.gov/protecting-yourself-wildfire-smoke
Pregnant people should take actions to reduce their exposure to wildfire smoke, which could affect the developing fetus. Other groups like young children, the elderly, those with pre-existing heart and lung disease, and outdoor workers also should take extra care to reduce their exposures to wildfire smoke. Monitor fires and air quality in your area through AirNow and follow instructions about exercise and going outside for "sensitive individuals."
Additional steps you can take to prepare include stocking up on medicine and buying groceries that don’t need to be cooked. In particular, frying or grilling food can make indoor air pollution worse. More information is available on the CDC website for people with chronic conditions, pregnant people, and children.
The California Air Resources Board Air Cleaner Information for Consumers has information about how to select a safe and effective air cleaner. Exercise caution in using air-cleaning devices in the home; some can produce ozone levels that are higher than health-based standards.

Best Practices for Emergency Managers
The Office of the Assistant Secretary for Preparedness and Response Technical Resources, Assistance Center, and Information Exchange (ASPR TRACIE) has collected lessons learned on Wildfires. An HHS emPOWER Program Story from the Field on Wildfires in Los Angeles County, California briefly explains how HHS emPOWER tools were used to rapidly conduct outreach to nearly 40 durable medical equipment (DME) and oxygen suppliers to provide recovery assistance to more than 600 individuals impacted by the historic 2017 wildfires.
Smoke-Ready Communities is an EPA and U.S. Forest Service Collaboration that is built around a series of interactive workshops and is designed to increase local readiness and improved public health response to wildfire smoke events.
Wildfire Smoke: A Guide for Public Health Officials -- the product of an inter-agency collaboration that includes the California Air Resources Board; California Office of Environmental Health Hazard Assessment; CDC; U.S. Forest Service; and EPA -- is designed to help local public health officials prepare for smoke events, to take measures to protect the public when smoke is present, and communicate with the public about wildfire smoke and health.
The CDC produced a summary for health departments on Evidence on the Use of Indoor Air Filtration as an Intervention for Wildfire Smoke Pollutant Exposure. For commercial buildings, the ASHRAE Planning Framework for Protecting Commercial Building Occupants from Smoke During Wildfire Events provides recommended heating, ventilation, and air conditioning (HVAC) and building measures to minimize occupant exposures and health impacts from smoke.
Workers face hazards even after fires are extinguished. The CDC’s Worker Safety During Fire Cleanup Fact Sheet reviews potential dangers during post-wildfire cleanup.
The HHS emPOWER collects and shares de-identified Medicare data to help response agencies take action to protect the health of Medicare beneficiaries who depend on vulnerable electrical medical equipment.
Resources for Wildland Fire Fighters
Wildland fire presents unique challenges and fire fighters must understand how to best protect their health and safety while fighting fires. Wildland Fire Fighting: Hot Tips to Stay Safe and Healthy reviews some recommended practices for fire fighters and their supervisors. Wildland Firefighter Health: Some Burning Questions offers information on hazards and risks associated with the wildland firefighting job.
Wildland fire fighting involves exposure to heat and prolonged, intense exertion. These factors increase the risk for rhabdomyolysis. The CDC Rhabdomyolysis site has additional information, factsheets, and wallet cards.
Drought Outlook for November, 2022 – January, 2023
Figure: The National Weather Service Climate Prediction Center's Monthly Drought Outlook is issued at the end of each calendar month and is valid for the upcoming month. The outlook predicts whether drought will persist, develop, improve, or be removed over the next 30 days or so. For more information, please refer to drought.gov.
Drought has expanded and intensified across the Pacific Northwest, Great Plains, Mississippi Valley, Ohio Valley, and Southeast since mid-September. This large drought expansion was due to an unusually dry September and a continuation of a dry pattern into early October. Improving drought conditions were limited to the East Coast and Southwest. Drought coverage decreased in recent weeks along the East Coast and drought is expected to end across the Northeast during the winter. Along with typically wet La Niña impacts, improvement or removal is forecast for the Pacific Northwest. This improvement or removal extends eastward to the north-central Rockies and southward to coastal northern California due in part to a relatively wet climatology during November through January. For the remainder of California and the Southwest, broad-scale persistence is more likely. Drought is also likely to persist with additional development across the Great Plains and Southeast. Drought improvement or removal is forecast for Hawaii, consistent with La Niña impacts and entering into their wet season. Alaska and Puerto Rico are likely to remain drought-free through the end of January 2023.
Drought Affects Health in Many Ways
Drought increases the risk for a diverse range of health outcomes. For example:
Low crop yields can result in rising food prices and shortages, potentially leading to malnutrition.
Dry soil can increase the number of particulates like dust and pollen that are suspended in the air, which can irritate the bronchial passages and lungs.
Dust storms can spread the fungus that causes coccidioidomycosis (Valley Fever).
If there isn’t enough water to flow, waterways may become stagnant breeding grounds for disease vectors like mosquitos as well as viruses and bacteria.
Drought's complex economic consequences can increase mood disorders, domestic violence, and suicide.
Long-term droughts can cause poor-quality drinking water and leave inadequate water for hygiene and sanitation.
Drought and Arsenic in Domestic Wells
Figure: Map showing the probability of having arsenic >10 μg/L (“high arsenic”) in domestic wells during drought. Arsenic occurs in groundwater due to chemical reactions between the rocks and water, lowering of water levels due to drought may cause chemical changes that release more arsenic from the rocks. Less water could also concentrate existing arsenic in the water. Hotspots generally reflect areas in the U.S. with high observed concentrations including New England (predominantly Maine and New Hampshire), a band in the upper Midwest, the southwest (most notably Nevada, southern Arizona, southern and central California, and isolated regions in all western states), and southern Texas.
Drought conditions can lead to elevated levels of naturally occurring arsenic in the water we drink. The risk of contamination increases the longer that a drought persists. In a study done by U.S. Geological Survey and Centers for Disease Control and Prevention in 2021, researchers estimated that over 9% (4.1 million) of the 44.1 million people in the lower 48 states who use private domestic wells were potentially exposed to unsafe levels of arsenic during drought conditions compared to about 6% (2.7 million people) during non-drought conditions. Chronic exposure to arsenic from drinking water is associated with an increased risk of several types of cancers, developmental issues, cardiovascular disease, adverse birth outcomes and impacts on the immune and endocrine systems.
Resources to Reduce Health Risks Associated with Drought
Drought poses many and far-reaching health implications. Some drought-related health effects occur in the short-term and can be directly observed and measured. But the slow rise or chronic nature of drought also can result in longer term, indirect health implications that are not always easy to anticipate or monitor.
General Preparedness
The Centers for Disease Control and Prevention (CDC) Drought and Health site and Ready.gov Drought site have information on the health implications of drought and how to prepare. The U.S. Drought Portal provides data, decision-support products, resources, and information on drought.

For Farmers
The Department of Agriculture offers programs that can help with drought recovery as well as those that can help farmers manage risk and build resilience. The Department’s Climate Hubs feature regional resources including vulnerability assessments and tools and a Climate, Agriculture, and Forest Science Webinar Series.
The U.S. Drought Monitor is an online, weekly map showing the location, extent, and severity of drought across the United States. The Department of Agriculture uses the Drought Monitor to determine a producer’s eligibility for certain drought assistance programs. You can report drought-related conditions and impacts within the U.S. and associated territories to the Drought Monitor.
The Department of Agriculture’s Natural Resources Conservation Service can help farmers conserve water and build resilience to drought, through conservation practices that improve irrigation efficiency, boost soil health, and manage grazing lands.

Mental Health
Drought is a slow-moving hazardous event, so the psychological effects of living through this type of disaster are more subtle and last longer than with other natural disasters. The Substance Abuse and Mental Health Services Administration (SAMHSA) Helpline and Text Service is available 24/7, free, and staffed by trained crisis counselors. Call or text 1-800-985-5990 to get help and support for any distress that you or someone you care about may be feeling related to any disaster.
Funded by the Federal Office of Rural Health Policy within the Health Resources and Services Administration, the Rural Health Information Hub offers several resources about drought and other stressors farmers face, as well as information and resources about farmers' mental health and prevention of suicide among farmers.
Learn more about drought and mental health at the SAMHSA’s Drought site. SAMHSA also has other disaster behavioral health resources, including newsletters and tip sheets. Check out SAMHSA’s newly launched Climate Change and Health Equity site for more information on the behavioral health impacts of climate change, preparing for a disaster, and resources for disaster planning and climate change education.
Best Practices for Emergency Mangers
The CDC’s When Every Drop Counts: Protecting Public Health During Drought Conditions—A Guide for Public Health Professionals is intended to assist public health officials, practitioners, and other stakeholders in their efforts first to understand and then to prepare for drought in their communities. It provides information about how drought affects public health, recommends steps to help mitigate the health effects of drought, identifies future needs for research and other drought related activities, and provides a list of helpful resources and too.
The CDC’s Preparing for the Health Effects of Drought: A Resource Guide for Public Health Professionals supplements When Every Drop Counts and is based on the results of a qualitative analysis of in-depth interviews with public health professionals, a review of state drought plans, and a literature review.
The Distribution of Lyme Disease
Figure: Lyme disease occurs primarily in the upper midwestern, mid-Atlantic, and northeastern United States. It is transmitted by blacklegged or “deer” ticks, which also transmit the agents of anaplasmosis, babesiosis and Powassan virus disease. The lack of dots in Massachusetts in 2018 is due to a difference in reporting standards, not an absence of Lyme disease.
An estimated 476,000 Americans are diagnosed and treated for Lyme disease each year. It is the most common vector-borne disease in North America. The incidence of Lyme disease in the United States has nearly doubled since 1991, from 3.74 reported cases per 100,000 people to 7.21 reported cases per 100,000 people in 2018. Maine, Vermont, and New Hampshire have experienced the largest increases in reported case rates. Climate is one of several factors that define when and where Lyme and other tickborne diseases are most likely to occur. Mild winters and warmer early spring temperatures are expanding the seasons when ticks are active, resulting in more weeks of the year that Americans are at risk of tick encounters. Expansion of the range of infected ticks puts an increasing number of communities at risk for Lyme and other tickborne diseases.
Which Seasons Are People Most Often Bitten by Blacklegged Ticks?
Figure: Emergency department (ED) visits for tick bites by month for 2020 – 2022. This graph shows 2022 following a similar pattern to previous years, with tick bites spiking in the spring. If this trend continues, there may also be a second, smaller spike in the fall.
In areas in the eastern US where Lyme disease cases are common, people are most likely to be bitten by blacklegged ticks at two times of year: from April through July when nymphs are active, and in September through November when adults are active. Nymphal ticks, which feed in late spring and early summer, pose a particularly high risk due to their abundance and small size (about the size of a poppy seed), which makes their detection difficult. However, adult deer ticks can also transmit the infection and may be more likely to be infected themselves. However, owing to their larger size (about the size of sesame seed), adult ticks are often detected and removed from people before disease transmission can occur. Lyme disease can be prevented by avoiding tick bites and prompt removal of ticks on people.

Figure: The different sizes of the blacklegged tick through 4 stages: egg, larvae, nymph, and adult.
How to Prevent Tick Bites and Tickborne Diseases
Tick bite prevention can take place before and after spending time outside. Before you go outdoors, use Environmental Protection Agency (EPA)-registered insect repellents, treat clothing and gear with products containing 0.5% permethrin, and talk to your veterinarian about the best tick prevention products for your dog. If possible, when spending time outside, avoid wooded and brushy areas with high grass and leaf litter where ticks may live. After spending time outdoors, check your body for ticks, take a shower within 2 hours, and check your clothing, gear, and pets for ticks that may have caught a ride into your home. You may also consider using landscaping methods to prevent ticks in the yard.
Resources to Reduce Health Risks Associated with Lyme Disease
The Centers for Disease Control and Prevention (CDC) Lyme Disease site has information on how to avoid Lyme Disease, common symptoms, and treatment. The Tick Bite Bot can assist you in removing attached ticks and seeking health care, if appropriate, after a tick bite. CDC’s Tickborne Diseases of the United States offers information on tick identification, tickborne diseases, and treatment. The CDC has also issued guidance for clinicians on caring for patients after a tick bite. CDC provides maps showing regions where ticks live and the counties where deer ticks and their associated pathogens have been detected in US counties.
The Food and Drug Administration (FDA) has additional information on symptoms, treatment, and prevention for people and pets. The Environmental Protection Agency (EPA) has a tool to help find the repellent that is right for you.

Updated Outlook for the 2022 Hurricane season
In August, the National Oceanic and Atmospheric Administration (NOAA) Climate Prediction Center slightly decreased the likelihood of an above-normal Atlantic hurricane season to 60% (lowered from the outlook issued in May, which predicted a 65% chance). NOAA’s outlook calls for 14-20 named storms (winds of 39 mph or greater), of which 6-10 could become hurricanes (winds of 74 mph or greater). Of those, 3-5 could become major hurricanes (winds of 111 mph or greater). So far, the season has seen three named storms and no hurricanes in the Atlantic Basin. In past years including 2021, July lulls have sometimes been followed by very active periods in August and September. An average hurricane season produces 14 named storms, of which 7 become hurricanes, including 3 major hurricanes. The Central Pacific, which includes Hawaii, is forecasted to have a below normal season. On average, the Central Pacific experiences about 1.5 hurricanes per year.
Hurricanes Affect Health in Many Ways
Hurricanes increase the risk for a diverse range of health outcomes. For example:
- Flood water poses drowning risks for everyone, including those driving in flood waters. Storm surge historically is the leading cause of hurricane-related deaths in the United States.
- Winds can blow debris—like pieces of broken glass and other objects—at high speeds. Flying debris is the most common cause of injury during a hurricane.
- Open wounds and rashes exposed to flood waters can become infected.
- Using generators improperly can cause carbon monoxide [CO] exposure, which can lead to loss of consciousness and death. Over 400 people die each year from accidental CO poisoning.
- Post-flooding mold presents risks for people with asthma, allergies, or other breathing conditions.
- Power failure during or after hurricanes can harm patients who critically depend on electricity-dependent medical equipment.
Health Impacts From Hurricane Harvey (2017)
This graph shows the observed changes in the population rates of treat-and-release emergency department (ED) visits following Hurricane Harvey in August 2017. Information on ED utilization is based on data from the AHRQ HCUP State Emergency Department Databases (SEDD). Using information from NOAA and the Federal Emergency Management Agency (FEMA), counties that were in the direct path of the hurricane were identified. For these counties, the percent change in the population rate of treat-and-release ED visits during and post-hurricane were compared to the pre-hurricane average utilization rates. Over a 7-week period after the hurricane, the largest increase in population rates of treat-and-release ED visits were observed for respiratory conditions, with relatively smaller increase for infections, injuries and all conditions.
Which parts of the country are at high risk from hurricanes?
Figure: This map of the United States is colored by the relative Risk Index rating for the Hurricane hazard. The characterization of risk across these counties are based on historical records on hurricane paths and intensity.
The Federal Emergency Management Agency (FEMA) provides information on the risk of different climate hazards across the 50 states and Washington DC through the National Risk Index (NRI) platform. The Risk Index leverages available data for natural hazard and community risk factors to develop a baseline relative risk measurement for each United States county and census tract. 291 counties across 16 states are estimated to have “extremely high,” “relatively high,” or “relatively moderate” hurricane risk. In these counties, the total population at risk is 60,095,904 people.
Who is at high risk from hurricanes in the counties estimated to have “extremely high,” “relatively high,” or “relatively moderate” hurricane risk?
Risk factors vary across the 291 counties identified to have “extremely high,” “relatively high,” and “moderately high” hurricane risk. Of these counties:
49 (17%) have a high number of people aged 65 or over, living alone.
153 (53%) have a high number of people without health insurance.
70 (24%) have a high number of uninsured children.
35 (12%) have a high number of people living in rural areas.
235 (81%) have a high number of Black or African American persons.
118 (41%) have a high number of people with frequent mental distress.
154 (53%) have a high number of people living in poverty.
57 (20%) have a high number of people spending a large proportion of their income on home energy.
157 (54%) have a high number of people with severe housing cost burden.
119 (40%) have a high number of people with electricity-dependent medical equipment and enrolled in the HHS emPOWER program.
150 (52%) have a high number of people in mobile homes.
89 (31%) have a high number of people with one or more disabilities.
178 (61%) are identified as highly vulnerable by CDC’s Social Vulnerability Index.
*“A high number” indicates that these counties are in the top quartile for this indicator compared to other counties
Resources to Reduce Health Risks Associated with Hurricanes
Health risks from hurricanes include drowning due to flood water, injuries, carbon monoxide poisoning after a power outage, infection during evacuation or shelter-in-place, post-storm exposure to mold, and psychological distress.

How warm will it be, and where, over the next 3 months?
Image source: https://www.cpc.ncep.noaa.gov/products/NMME/current/images/NMME_ensemble_tmp2m_us_season1.png
Figure: The North American Multi-Model Ensemble (NMME) predicts that average temperature over the next 3 months (September – November) will be 1.8–3.6°F (1–2°C) hotter than average across parts of the contiguous U.S. For more information about this model or prediction, please refer to the NMME website.
For November – January, the North American Multi-Model Ensemble (NMME) predicts that the average temperature will be 0.9 – 3.6°F (.5 – 2°C) above-normal for most of the continental United States. However, parts of Alaska will experience temperatures 0.45 – 1.8°F (0.25 - 1°C) cooler than average. The NMME integrates multiple forecasts of the next 90 days to build the best estimate of temperatures and precipitation over that time frame. Note that although many regions may expect a warmer 90-day average temperature, this is not the same as your local weather forecast, in which large fluctuations in temperature may be predicted from day to day.
Health Impacts During the Heat Dome of 2021
During June–July 2021, the western U.S. experienced a record-breaking heat wave that lasted for several days. Estimated heat-related deaths and illnesses demonstrate the tragic toll of the heat wave on public health. Comparing the health records from June 26–July 10 between 2021 and 2020, heat-related deaths increased from 2 to 145 in Washington, 0 to 119 in Oregon, and 12 to 25 in California. These estimates were provided by the California Department of Public Health, Oregon Health Authority, and Washington State Department of Health. For context, the CDC estimates an average of 702 heat-related deaths per year for the entire U.S. (based on 2004–2018 data).
Heat Affects Health in Many Ways
Warmer temperatures increase the risk for a diverse range of health risks. For example:
- An increased risk of hospitalization for heart disease.
- Heat exhaustion, which can lead to heat stroke if not treated, can cause critical illness, brain injury,
and even death. - Worsening asthma and chronic obstructive pulmonary disease (COPD) as heat increases the production of ground-level ozone.
- Dehydration, which can lead to kidney injury and blood pressure problems. Some kidney damage can become irreversible with repeated or untreated injury.
- Violence, crime, and suicide may increase with temperature, adding to the rates of depression and anxiety already associated with climate change
- Some medications increase the risk of heat-related illness. These include diuretic medicines (sometimes called “water pills”), antihistamine medicines (including many allergy medicines), and many antipsychotic medicines used to treat a variety of psychiatric and neurologic illnesses. Please review this list of common psychiatric medications that can impair the body’s normal ability to cool itself.
Spotlight on Health Equity: Health Impacts in Rural Areas

In April 2022, Agency for Healthcare Research and Quality used the Healthcare Cost and Utilization Project (HCUP) 2016–2019 to estimate county-level population rates of emergency department (ED) visits with a diagnosis directly indicating heat exposure. The analysis was limited to records of ED visits, regardless of hospital admission, at community hospitals, excluding rehabilitation and long-term acute care facilities, with any-listed diagnosis directly indicating heat exposure. This analysis includes ED data from 2,550 counties in 39 States and the District of Columbia, representing 85 percent of the population and 81 percent of all counties in the United States in 2019. Among the 1,122 rural counties, 152 (13.5%) had heat-related ED visit population rates of 85 or more per 100,000 population (i.e., 90th percentile of population rates). In contrast, among the 344 large metropolitan counties, 8 (2.3%) had heat-related ED visit population rates in the 90th percentile. The report highlights that a larger proportion of rural than large metropolitan counties experience a high rate of heat-related illness, although there are more heat-related ED visits in large metropolitan areas (n=135,585 ED visits) than in rural areas (n=30,115 ED visits).

Best Practices for Emergency Managers
This CDC report on Heat Response Plans reviews steps emergency managers and health officials can take to develop and implement measures to protect their communities. Spikes in energy demand should be expected during summer months as air conditioning use increases. The combination of sagging power lines (copper expands as it heats up, thus increasing impedance and reducing throughput) and increased energy demands can cause power failures that make certain populations more vulnerable when the risk is highest. The HHS emPOWER pcollects and shares de-identified Medicare data to help response agencies take action to protect the health of Medicare beneficiaries who depend on vulnerable electrical medical equipment.
Real-time information on health impacts from extreme heat can also help decision-makers implement strategies to reduce risk. CDC’s Heat and Health Tracker provides regular updates on the rate of heat-related Emergency Department visits (organized by HHS regions) and observed temperature.
If you are a local organization planning to open a cooling shelter, consider referring to CDC guidance on how to maintain a safe shelter during a heat wave.
Check out SAMHSA’s newly launched Climate Change and Health Equity site for more information on the behavioral health impacts of climate change, preparing for a disaster, and resources for disaster planning and climate change education.
