* Excessive Heat Watch: Issued when there is a 50% or greater chance of an excessive heat warning being issued within 12 to 48 hours. * Excessive Heat Warning: Issued when dangerous heat conditions are expected to develop within 12 to 24 hours.

Impact of Excessive Heat

Excessive heat can be extremely dangerous, especially for vulnerable populations such as the elderly, young children, and those with chronic health conditions. Heat-related illnesses can range from mild heat cramps to life-threatening heat stroke.

During an excessive heat warning, it is crucial to take precautions to stay cool and hydrated. Stay indoors in air-conditioned spaces as much as possible, avoid strenuous activity, drink plenty of fluids, and wear loose-fitting, lightweight clothing. If you must go outside, take breaks in shaded areas and seek medical attention if you experience any symptoms of heat illness.
