LAS VEGAS >> A dangerous heat wave continued to bake much of the Southwest today, sending people to the hospital and tied or broke records this weekend.
The mercury shot up to 117 degrees in Las Vegas today to tie the city's all-time record high and to cause more discomfort for residents and tourists in the sprawling desert city.
National Weather Service forecasters say since Las Vegas began keeping weather records in 1937, the only other times the temperature reached 117 degrees were on July 19, 2005 and July 24, 1942.
Temperatures continued steadily upward after Las Vegas saw an overnight low of 89 degrees this morning. That reading tied the city's record highest minimum temperature for the date set in 2009 and 1994.
Las Vegas authorities say seven more people were taken to the hospital with heat-related problems as of early this afternoon and the most serious case involved an adult who has no air conditioning at his home.
On Saturday, a man died and another was hospitalized in serious condition in heat-aggravated incidents in Las Vegas.
The National Weather Service's thermometer recorded a peak temperature of 128 degrees in Death Valley National Park, which ties the record for the hottest June day anywhere in the country. However, the Los Angeles Times reports that the National Park Service thermometer — 200 yards away — recorded a temperature of 129.9, which shatters the record for June.
Triple-digit heat struck again elsewhere in Southern California, while metropolitan Phoenix saw just a slight drop in temperatures after experiencing record-breaking heat Saturday.
Six half-marathon runners in Southern California were hospitalized TOday for heat-related illnesses. A day earlier, paramedics responding to a Nevada home without air conditioning found an elderly man dead.
Runners in the Southern California race who required medical attention were extremely dehydrated, and some experienced cramps, Pasadena Fire Department spokeswoman Lisa Derderian said. Several other runners were evaluated along the route but weren't taken to the hospital, she said.
Paramedics were deployed along the 13.1-mile race, and buses with air conditioning were provided for runners to cool off. The event was supposed to be a marathon, but it was downgraded due to low turnout last year.
Hikers, bikers and dog walkers were scarce on typically busy trails in the Santa Monica Mountains above Los Angeles. At midday, two women and a panting German shepherd huddled in a rare sliver of shade along a fire road before striking out in the hot sun.
Atop San Vicente Peak, cyclist Jeff Disbrow, 49, of Santa Monica was clad in black and lathered in sweat as he took a break and refilled his water bottle.
"It's not the best day to be out here — unless you want to suffer," he said. "It's like Arizona."
In Utah, a record 105-degree heat caused an interstate on-ramp to buckle in Salt Lake City, and hampered firefighters in their battle against three wildfires. The Interstate 215 on-ramp had to be closed for four hours Saturday night after a short section of it expanded, Utah Department of Transportation spokesman John Gleason said.
The section looked like a pothole before it was repaved, he said. No problems were reported, and traffic was rerouted around the closed lane.
Phoenix Fire Department spokesman Larry Nunez said the city hasn't seen any deaths that were classified as heat-related, but emergency workers have gotten 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 metro Phoenix since authorities started keeping temperature records more than 110 years ago. The high temperature for the metro area hit 115 on Sunday.
Temperatures could drop slightly in Phoenix within the coming days as monsoon storms are expected to make their way through 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. In Northern California, Redding reported a high of 110, Sacramento had 107 while Fresno saw 109.
