The National Weather Service has issued an excessive heat warning for the Las Vegas Valley as the temperature soars to a high of 112 degrees today, officials said.
The warning — upgraded from a watch last night — is in effect from 10 a.m. today to 10 p.m. Wednesday as a high pressure system settles over the region, bringing the hottest weather so far this year, said Jim Harrison, a meteorologist with the Las Vegas field office.
The hottest temperatures will occur in the late afternoon and linger until about 6 p.m., Harrison said. The overnight low is expected to be 88 degrees.
“It’s going to be hot for much of the night,” Harrison said. “We’re not going to have any real break from the heat.”
The normal high for today is 103 degrees, but the extreme heat moved into the valley yesterday. The highest temperature recorded at McCarran International Airport yesterday was 111 degrees, Harrison said.
The high temperature will drop to 108 degrees Thursday and 105 degrees by Sunday, edging closer to normal, Harrison said.
The prolonged period of extreme heat can put extra stress on the body, so meteorologists urge people to drink lots of water, limit outdoor activities, wear light-weight clothing, stay in air conditioned buildings and monitor those most at risk for heat-related illness — the homeless, elderly, children and pets.
