...Excessive heat warning in effect until 8 PM EDT this evening...

The National Weather Service in Raleigh has issued an excessive
heat warning...which is in effect until 8 PM EDT this evening.
The heat advisory is no longer in effect. 

The combination of very high humidity and temperatures near 100
degrees will produce dangerous heat indices at or above 110
degrees this afternoon. Additional heat advisories or warnings will
likely be needed through the weekend as the heat wave continues.

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
sunshine...and check up on relatives and neighbors. Heat of this
magnitude can be particularly deadly for the elderly...those with
illnesses...and for outdoor workers such as farm laborers.

Stay safe, everyone.
