LAS VEGAS — High temperatures brought discomfort and hazards to much of the Southwest on Sunday as many parts were coping with record-breaking heat and bracing for more sizzling temperatures.
Triple-digit heat was on tap for the valleys and desert regions of Southern California at least through Tuesday. Metropolitan Phoenix saw a slight drop in temperatures Sunday after experiencing record-breaking heat a day before.
Six half-marathon runners in Southern California were hospitalized Sunday for heat-related illnesses. Runners who required medical attention were extremely dehydrated, and some experienced cramps, said Pasadena Fire Department spokeswoman Lisa Derderian.
On Saturday, paramedics responding to a Nevada home without air conditioning found an elderly man dead. Another Nevada man was hospitalized in serious condition due to a heat-related ailment as the temperature soared to 115 degrees.
Phoenix Fire Department spokesman Larry Nunez said the city hasn’t seen any deaths that were classified as heat-related, but emergency workers have received 98 heat-related calls within the metro area since Friday morning.
The 119-degree high in Phoenix on Saturday marked the fourth-hottest day in that metro area since authorities started keeping temperature records more than 110 years ago.
Temperatures could drop slightly in Phoenix within the coming days as monsoon storms are expected to cross the state. Such storms could bring cloud cover but could produce more humidity and possibly contribute to dust storms.
Several Southern California communities set same-day record highs Saturday including Palm Springs, where the mercury peaked at 122 degrees.
Death Valley, the hottest place on the planet, reached 127 degrees Saturday. It was forecast to be 1 degree hotter Sunday. That is still shy of the record high of 134 degrees, set nearly a century ago on July 10, 1913.
In Las Vegas, temperatures were on the rise again after the city reported a record overnight low of 89 degrees Sunday.
With the temperature at 111 degrees by midday Sunday, National Weather Service forecaster Dan Berc said Las Vegas could also break its record high of 117 degrees set in 2005 and 1942. Forecasters had called for a high of 116 degrees.
In central Arizona on Sunday, a 1-square-mile wildfire led to the evacuation of 120 homes. State Forestry Division spokeswoman Carrie Dennett said no homes have been lost in the fire northwest of the Yavapai County community of Yarnell, but the blaze was within a half-mile of some homes.
