The Southwest is tying a number of record temperatures as a heat wave settles in.
On Sunday, the National Weather Service recorded a peak temperature of 128 degrees in Death Valley National Park. That ties the record for the hottest June day anywhere in the country.
Meanwhile, the Los Angeles Times reported that the National Park Service thermometer, just 200 yards away, recorded a temperature of 129.9, which shatters the June record.
The heat caused problems for half-marathoners racing in Pasadena, Calif., on Sunday. Six were hospitalized for heat-related illness. A Pasadena Fire Dept. spokeswoman said the runners were extremely dehydrated and some experienced cramps.
Paramedics set up along the 13.1-mile race route, and air conditioned buses were available for runners to cool off. Officials had originally planned a marathon but downgraded the event due to low turnout last year.
In Las Vegas on Saturday, paramedics found an elderly man dead in a home without air conditioning. Officials recorded 117 degrees on Sunday, tying the city's record high.
In Utah, a record 105-degree heat buckled an interstate on-ramp in Salt Lake City. Authorities closed the Interstate 215 on-ramp for four hours to repave the area.
In Phoenix, the metro area temperature hit 115 on Sunday. Emergency workers have received 98 heat-related calls since Friday morning.
Meanwhile, monsoon storms are expected to make their way through Arizona in the coming days, which could cause temperatures to drop slightly.
