Excessive heat warning begins Monday for Las Vegas Valley
An excessive heat warning went into effect at noon Monday in the Las Vegas Valley, says the National Weather Service.
The warning covers all of the region except those at high elevations and will continue through 9 p.m. Wednesday.
The highs for Monday should reach 108 degrees, just a degree below the daily record set in 2001.
“We changed the excessive heat watch (in an earlier forecast) to a heat warning and moved it up several hours,” said weather service meteorologist John Adair. “The upward heat trend kicked up a notch on Sunday.”
High temperatures around Las Vegas, Pahrump, and Moapa will range from 106 to 110 degrees through Wednesday and from 110 to 115 degrees in the lower Colorado River Valley.
Tuesday’s high is also forecast to be 108, 2 degrees below the record for the date set in 2017.
“It’s just going to be warm all week with no significant cooling forecast,” Adair said.
Heat-related illnesses such as heat exhaustion and heat stroke will be possible. People most vulnerable include those who spend lots of time outdoors, those without air conditioning, young children, the elderly and those with chronic ailments.
Adair said the next chance of precipitation is about a week away.
“There is about a 20 percent chance of some rain creeping into the Spring Mountains starting next Monday,” he said.
