Extreme heat is a period of high heat and humidity with temperatures above 90 degrees for at least two to three days. In extreme heat your body works extra hard to maintain a normal temperature, which can lead to death. Extreme heat is responsible for the highest number of annual deaths among all weather-related hazards.
Similarly, severe cold weather can cause a higher risk for hypothermia, frostbite, carbon monoxide poisoning, heart attacks from overexertion, and even car accidents due to snow and ice.
Remember to check in on your neighbors, especially those who are elderly or disabled, to ensure they are safe.
