PRECAUTIONARY/PREPAREDNESS ACTIONS...
A Heat Advisory means that hot weather conditions are occurring or
expected. This will create a situation in which heat illnesses are
possible.
Never, ever, leave children or pets alone in enclosed vehicles, not
even for a few minutes. Car interiors can reach lethal temperatures
in a matter of minutes.
Stay indoors and seek air-conditioned buildings. Drink water more
than usual, and avoid dehydrating alcoholic, sugary, or caffeinated
drinks. Dress for the heat by wearing lightweight and light colored
clothing. Eat small meals and eat more often. Monitor those with a
higher vulnerability to heat, including small children. Check in on
family, friends, and neighbors, especially the elderly. If engaging
in outdoor activity, take longer and more frequent breaks and avoid
the hottest parts of the day.
