In addition to the hot afternoons, little relief from the heat is expected overnight.  With little to no cooling influence from the ocean and a somewhat humid air mass in place, nights will remain quite uncomfortable away from the coast.

Precautionary/Preparedness actions:

An excessive heat warning means that a prolonged period of dangerously hot temperatures will occur.  The combination of hot temperatures and high humidity will combine to create a dangerous situation in which heat illnesses are likely.  Drink plenty of fluids, stay in an air conditioned room, stay out of the sun, and check up on relatives and neighbors.
