The official temperature in Las Vegas hit 117 degrees Sunday afternoon, tying the all-time high-temperature record for the area, the National Weather Service said.
Las Vegas also reached 117 degrees in July 1942 and July 2005.
The 117 mark was recorded about 4:50 p.m. Sunday near McCarran International Airport, the official recording station for Las Vegas temperature. That breaks the June record of 116 degrees, set in 1940, the weather service said.
Seven people were hospitalized throughout the Las Vegas Valley on Sunday, bringing the weekend's number of heat-related hospitalizations up to 28.
Las Vegas Fire & Rescue responded to 15 heat-related calls over a 14-hour stretch from midnight Saturday to 2 p.m. Sunday, Las Vegas Fire & Rescue spokesman Tim Szymanski said in a statement.
All of the calls were for adults between the ages of 20 and 67, with the most of the calls for people between 30 and 50, Szymanski said.
Many of Sunday's calls were for heat exhaustion, and several of the victims were close to heat stroke, Szymanski said. None of the calls was life-threatening, he said.
As the heat continues, responders might deal with more serious calls, Szymanski said.
Since Friday, there have been 78 calls to 911 concerning heat-related illness, and 28 people have been hospitalized, Szymanski said.
The record-breaking temperatures come in the middle of a weekend heat wave that had residents seeing temperatures as high as 115 degrees Saturday.
The heat wave is expected to last through Thursday, the weather service said.
