Excessive heat watch starts Tuesday, lasts through weekend
An excessive heat watch will be in place for the Las Vegas region starting Tuesday through Sunday evening.
Temperatures will be well above normal and range from 105 to 115 across the Mojave Desert and Lake Mead areas with temperatures reaching 115 to 123 in Death Valley, says the National Weather Service.
Afternoon highs in Las Vegas during the last week of August are just above 100.

The weather service advises people to monitor the latest forecasts and warnings for updates while also being prepared to drink plenty of fluids, stay in an air-conditioned room, stay out of the sun and to check up on relatives and neighbors.
Temperatures were several degrees below normal during the past month of monsoon conditions while humidity levels were elevated.
The Monday high is expected to be near 103 in Las Vegas with light winds.
After a Tuesday morning low near 83, the high should reach 106.
Wednesday is forecast to reach 109 with a Thursday high of 110. Conditions will be similar through the weekend.
Lake Mead stays on upswing
The surface of Lake Mead was at 1,044.23 feet above sea level at 2 p.m. Monday, a rise of 3.52 feet from its summer low of 1,040.71 feet on July 27.
The active monsoon season began in late July, drenching Arizona considerably more often than the Las Vegas Valley, even though the weather service says it was the most active monsoon season in the valley in a decade.
