... 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.
