Severe Weather & Your Health
Extreme weather patterns carry a wide range of implications regarding human populations. In addition to the high potential for injuries and deaths during hurricanes, floods, and other weather-related disasters, it's important to know the additional health risks associated with extreme weather conditions.
A variety of weather situations can have an impact of an outdoor event. Please consult this checklist to see if there are things you need to consider for your event to keep your attendees safe and healthy.

Extreme Heat
As temperatures in Maryland start heating up, make sure to take the necessary precautions to avoid heat-related illnesses. While anyone can be a victim of heat-related illness, highest risk groups include people under age of 5 or over age 65, people with chronic illness, people taking certain medications, and those who are exercising or working outdoors. COVID-19 presents many challenges in the summer since places where citizens generally go to cool off, including cooling centers and libraries are likely to remain closed. Finding ways to stay cool and safe, both at home and outside, are more important this summer than ever.
Hot Weather Tips:
- Stay indoors as much as possible and limit exposure to the sun.
- Stay on the lowest floor out of the sunshine if air conditioning is not available.
- Consider spending the warmest part of the day in air conditioned places when possible.
- Drink plenty of water and avoid alcoholic beverages.
- Dress in loose-fitting, lightweight, and light-colored clothes that cover as much skin as possible.
- Protect face and head by wearing a wide-brimmed hat.
- Check on family, friends, and neighbors who do not have air conditioning.
- Never leave children or pets alone in closed vehicles.
- Avoid strenuous work/exercise during the warmest part of the day. Use a buddy system when working in extreme heat, and take frequent breaks.
- Please be aware that heat exposure is cumulative and repeated exposure will reduce the time you can spend in the sun without feeling the effects.
Heat-Related Illness
During extremely hot and humid weather, your body’s ability to cool itself is challenged. When the body heats too rapidly to cool itself properly, or when too much fluid or salt is lost through dehydration or sweating, body temperature rises and you or someone you care about may experience a heat-related illness. Learn the symptoms and what to do if you or a loved one shows signs of having heat-related illness.
Extreme Cold
Extremely cold air comes every almost every winter in Maryland. The arctic air, together with brisk winds, can lead to dangerously cold wind chill values. People exposed to extreme cold are susceptible to frostbite in a matter of minutes. Areas most prone to frostbite are uncovered skin and the extremities, such as hands and feet. Hypothermia is another threat during extreme cold. Hypothermia occurs when the body loses heat faster than it can produce.
Cold Weather Tips:
- Watch for Signs of Frostbite. These include loss of feeling and white or pale appearance in extremities such as fingers, toes, ear lobes, and the tip of the nose. If symptoms are detected, get medical help immediately
- Watch for signs of hypothermia. These include uncontrollable shivering, memory loss, disorientation, incoherence, slurred speech, drowsiness, and apparent exhaustion. If symptoms of hypothermia are detected, get the victim to a warm location, remove wet clothing, warm the center of the body first and give warm, non-alcoholic beverages if conscious. Get medical help as soon as possible.
- If you must go outside, wear several layers of loose-fitting, lightweight, warm clothing rather than one layer of heavy clothing. The outer garments should be tightly woven and water repellent.
- Avoid overexertion when shoveling snow. Overexertion can bring on a heart attack - a major cause of death in the winter. Use caution, take breaks, push the snow instead of lifting it when possible, and lift lighter loads.
- Maintain ventilation when using kerosene heaters to avoid build-up of toxic fumes. Refuel kerosene heaters outside and keep them at least three feet from flammable objects.
- Keep an eye on neighbors, particularly those who are elderly, who are caring for young children or living alone. Offer to assist with trips to the grocery, medical appointments or other errands.
- If a home loses power, close off unneeded rooms and and have family members congregate in the warmest room with a supply of blankets to help conserve the heat in the house.
- Do not use candles for light. Candles are a leading cause of house fires. Instead, stock battery-operated lights, such as flashlights, and a good supply of batteries.
- Keep a battery-operated radio and batteries on hand to stay abreast of news and information. Keep cell phones fully charged.
- Do not leave pets outdoors for a long time during cold weather. Pets can suffer hypothermia and serious illness, so do everything possible to keep them safe and warm.
Floods
Floods are the most common natural disasters in the United States. You can take steps to reduce the harm caused by flooding. Learn how to prepare for a flood, stay safe during a flood, and protect your health when you return home after a flood.

Flash Flooding / Turn Around, Don’t Drown
- Avoid areas already flooded, especially if the water is flowing fast. Do not attempt to cross flowing streams. Turn Around Don't Drown
- Roadbeds may be washed out under flood waters. Never drive though flooded roadways. If your vehicle is suddenly caught in rising water, leave it immediately and get to higher ground.
- Be especially cautious at night when it is harder to recognize flood dangers.
Exposure to Flood Waters
- Flood waters are likely to contain sewage as well as gasoline, solvents and other chemicals.
- Avoid contact with flood waters if at all possible.
- Individuals exposed to flood waters should take a bath or shower with clean water and soap.
- Clean clothing and other belongings by laundering.
- If you have open cuts exposed to flood water, wash with soap and disinfected water and apply antibiotic ointment. If redness, swelling or drainage of the wound occurs, see a physician.
Hurricanes
Hurricanes can cause damage to coastlines, as well as up to several hundred miles in-land. Hurricanes can also produce winds in excess of 155 miles per hour, tornadoes, microbursts, heavy rain, and thunderstorms. Flooding and debris from forceful winds are often the deadly and destructive results of a Hurricane. It is vital to understand your vulnerability to storm surge, flooding, and wind.
Here is your checklist of things to do BEFORE a hurricane:
- Prepare an emergency kit including food, water, a flashlight, batteries, cash, first aid supplies, medication (30 day supply), copies of your critical information and other critical supplies.
- Make sure your pets are prepared. Include food and water for pets in your emergency kit.
- Keep your vehicles fueled and devices charged.
- Have some cash on hand in case you need to pay for something if the power is out.
- Sign up for text or email alerts for emergency notifications. ALERT Frederick County is an emergency notification system that allows Frederick County officials to contact you whether you are home or on the go. Sign up here: FrederickCountyMD.gov/Alert.
- Create a family communications plan. Get together with your family to agree on the ways to contact one another in an emergency and to identify meeting locations.
- Familiarize yourself with hurricane evacuation routes in your area and how to find higher ground. Determine where you would go and how you would get there if you need to evacuate. To learn about Maryland evacuation zones, visit: https://mdem.maryland.gov/action/Pages/know-your-zone-md.aspx.
- For additional information on how to prepare, visit:
DURING a hurricane:
- Stay tuned in to radio and TV stations for official weather information.
- Follow instructions issued by local officials. Leave immediately if ordered!
- If NOT ordered to evacuate:
- Take refuge in a small interior room, closet of hallway on the lowest level during the storm. Put as many walls between you and the outside as you can.
- Stay away from windows, skylights, and glass doors.
- If the eye of the storm passes over your area, there will be a short period of calm, but at the other side of the eye, the wind speed rapidly increases to hurricane force winds coming from the opposite direction.
AFTER a hurricane:
- Continue listening for the latest updates regarding extended rainfall and subsequent flooding after the hurricane has ended.
- If you evacuated, return home only when officials say it is safe.
- Once home, drive only if necessary and avoid flooded roads and washed-out bridges. If you must go out, watch for fallen objects in the road, downed electrical wires, and weakened walls, bridges, roads, and sidewalks that might collapse.
- Walk carefully round the outside of your home to check for loose power lines, gas leaks, and structural damage.
- Stay out of any building if you smell gas, if floodwaters remain around the building, if the building or home was damaged by fire, or if the authorities have not declared it safe.
- Carbon monoxide poisoning is one of the leading causes of death after storms in areas dealing with power outages. Never use a portable generator inside your home or garage.
- Use battery-powered flashlights. Do NOT use candles. Turn on your flashlight before entering a vacated building. The battery could produce a spark that could ignite leaking gas, if present.
Health and Safety Concerns for All Disasters
