An excessive heat warning is issued within 12 hours of the onset of extremely dangerous heat conditions, according to the National Oceanic and Atmospheric Administration (NOAA). This type of warning is typically issued when the maximum heat index temperature is to be 105 degrees or higher for at least two days and nighttime temperatures stay above 75 degrees, however, those criteria can vary across the country.

An excessive heat watch is issued when conditions are likely for an excessive heat event in the upcoming 24 to 72 hours.

An excessive heat outlook is issued when there is potential for an excessive heat event in the upcoming three to seven days.

NOAA suggests drinking plenty of water and eating cool, easy-to-digest foods such as fruit or salads while inside. Take a cool bath or shower. Use air conditioners or spend time in air-conditioned locations. Do not direct the flow of portable electric fans toward you if the room's temperature is over 90 degrees; the blowing air is more likely to dehydrate you faster. Make sure rooms are well-vented.

According to NOAA, if you must go out during excessive heat events, you should dress in lightweight, loose clothing that reflects heat and sunlight. Drink plenty of water and minimize exposure to the sun. Do not leave valuable electronic equipment, such as cellphones and GPS units, in hot vehicles. Children, seniors and anyone with underlying health conditions should stay in the coolest places available to them.
