Excessive Heat Watch
Statement as of 8:44 PM MST on August 27, 2008/

... Excessive heat watch in effect Thursday afternoon...

The National Weather Service in Las Vegas has issued an excessive
heat watch... which is in effect from 1 PM Thursday afternoon until
6 PM Thursday evening... for elevations below 4000 feet.

A hot dry air mass will develop over much of the southern Great
Basin and Mojave Desert Thursday. Afternoon temperatures will be
hot enough to produce a potentially dangerous health hazard if
proper precautions are not taken.

An excessive heat watch means that a period of hot temperatures
is expected. The hot temperatures will create a dangerous
situation in which heat-related illnesses are possible. Use extra
caution and remember to drink plenty of fluids... stay out of the
sunshine and in an air-conditioned room if possible and check up
on elderly relatives and neighbors.
