Weather officials have issued an excessive heat watch starting Sunday for the Las Vegas Valley, with temperatures expected to peak as high as 112 degrees on Monday.
High pressure traveling up from Mexico will build over the next few days and create the above-normal temperatures, said Chris Outler, a forecaster with the National Weather Service.
The heat watch covers late Sunday morning through Monday evening for elevations below 4,000 feet.
Sunday’s high is expected to reach 110 degrees in the valley and 112 at Lake Mead National Recreation Area. Temperatures on Monday could hit 112 in the valley and 113 at Lake Mead. Death Valley, meanwhile, may get as hot as 119 degrees on Sunday and 122 degrees on Monday.
The weather service considers thermometer readings above 107 to be excessive.
Heat is the top weather-related killer in Las Vegas and the U.S., according to the National Weather Service.
The homeless, elderly, children and those with health issues are most at risk. Animals left without shade or water could also succumb to the heat.
