The weather forecast calls for extreme heat across the region over the next several days, with a potentially dangerous heat wave that could last into next week. Heat-related deaths and illnesses are preventable. Despite this fact, more than 600 people in the United States are killed by extreme heat every year according to the Centers for Disease Control and Prevention. The Frederick County Department of Emergency Preparedness and the Frederick County Health Department want you to take action now and make a plan to stay safe in the heat. Very hot weather can make people sick, even healthy adults. Older adults, those who are pregnant, infants and young children, people experiencing homelessness, and people with pre-existing health conditions are at higher risk for heat-related illness. If you think someone is having a medical emergency, call 911.
