Conditions at night will also remain hot and humid, especially in more urbanized areas, according to the NWS.

Drink plenty of fluids, stay out of the sun and in air-conditioned areas, and dress in loose, light-colored clothing. Remember to check in on older neighbors and relatives, and keep pets inside or in a cool and ventilated location with access to water.
