The warning urges residents and visitors in the above communities to seek indoor shelter during the hottest hours of the day, take frequent breaks from the heat, drink plenty of water, and make sure no pets or people are left inside closed vehicles for any length of time.

“Monitor for symptoms of heat stroke or heat exhaustion, such as high body temperature, lack of sweat, confusion, fainting, and unconsciousness,” read the alert.
