LAS VEGAS (KLAS) — An excessive heat warning is now in effect for the next three days as temperatures continue to inch up in the triple-digit zone.

Clark County has opened several cooling stations around the valley for those who need a place to stay cool.

Tuesday’s high temperature was 101 degrees and Wednesday’s was 106 degrees. The temperature is expected to climb to 107 Thursday and even higher on Friday and Saturday at 109 degrees which would set a new daily record. Those temperatures are about 10 degrees above normal.

The heat warning is in effect for most of Clark County until 8 p.m. Saturday but it extends until 8 p.m. Sunday for Lake Mead and Lake Mohave. Temperatures are expected to dip just below 100 degrees on Monday.

People are advised to limit outdoor activity to cooler times of the day and drink plenty of water to avoid dehydration.
