A fountain in a water park offered some relief for Hayden Slykhuis, 4, as the high in Las Vegas hit 115 on Saturday. Sunday was no better, with an excessive-heat warning in force until nearly midnight.


June 2013. It's in the book.

It was Tucson's first June to see triple-digit temps every day, according to the National Weather Service. Sunday topped out at 111 degrees.

Unfortunately, the heat wave continues into July and even a 30 percent chance of rain on Monday and Tuesday and a 40 percent chance on Wednesday won't bring the mercury below the 100-degree mark.

Highs between 101 and 105 degrees are expected through the weekend.

Tucsonans will just have to "endure," said Hans Hanson, a meteorological technician with the weather service in Tucson.

But, it could be worse.

Death Valley, the hottest place on the planet, reached 127 degrees over the weekend - still shy of the record high of 134 degrees, set nearly a century ago on July 10, 1913.

Several Southern California communities set record highs including Palm Springs, where the mercury peaked at 122 degrees. Six half-marathon runners were hospitalized Sunday due to the extreme heat.

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 there Sunday was 115.

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.

In Las Vegas, temperatures were on the rise again after the city reported a record warm overnight low of 89 degrees Sunday.

One man died and another was hospitalized in serious condition in Las Vegas over the weekend as temperature soared to 117 degrees Sunday.

In Utah, a heat wave caused an interstate on-ramp to buckle in Salt Lake City, authorities said Sunday.

The I-215 on-ramp had to be closed for four hours after a short section of it expanded and buckled in record 105-degree heat, said Utah Department of Transportation spokesman John Gleason.
