... Review of the National Weather Service excessive heat program...

Southeast South Carolina and southeast Georgia is no stranger to
excessive heat. However, there are times when unusually hot and
potentially dangerous conditions do occur. About 175 americans
succumb to the taxing demands of heat every year.

Forecasters at the National Weather Service in Charleston are
responsible for the timely issuance of watches, warnings and
advisories for excessive heat whenever conditions meet or exceed
regionally defined criteria.

For southeast South Carolina and southeast Georgia, the following
criteria are used to determine when watches, warnings and
advisories for excessive heat are issued:

Excessive heat watch
--------------------
an excessive heat watch is issued whenever there is a 50 percent
or greater probability that maximum heat index values will meet or
exceed 115 degrees within 12 to 48 hours.

Excessive heat warning
----------------------
an excessive heat warning is issued whenever there is an 80
percent or greater probably that maximum heat index values will
meet or exceed 115 degrees within 12 to 24 hours.

Heat advisory
-------------
a heat advisory is issued whenever maximum heat index values of
105-114 degrees are expected to occur for at least two hours.
