Extreme Heat
A heatwave is a period where local excess heat accumulates over a sequence of unusually hot days and nights with temperatures above 90 degrees for at least two to three days. Heatwaves and prolonged excess heat conditions are increasing in frequency, duration, intensity and magnitude due to climate change. Even low and moderate intensity heat waves can impact the health and well-being of vulnerable populations. 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. Many populations in tropical and subtropical climates are chronically exposed to high temperatures. In mid to high latitudes, population exposure excess heat is seasonal.

Winter Weather
Winter storms create a higher risk of car accidents, hypothermia, frostbite, carbon monoxide poisoning, and heart attacks from overexertion. Winter storms, including blizzards, can bring extreme cold, freezing rain, heavy snow, ice and high winds.
A winter storm can:
- Last a few hours or several days.
- Cut off heat, power and communication services.
