The “extreme heat” has arrived in Las Vegas. Just in time for the weekend.
An extreme heat warning takes effect at 9 a.m. today and is set to expire at 11 p.m. Saturday, according to the National Weather Service.
The agency is forecasting a high of 103 degrees for today and 104 degrees for Saturday. The heat could break records both days.
The heat warning covers much of the Mojave Desert, including Las Vegas and the Colorado River Valley. Temperatures over 115 are likely in Death Valley.
The agency is warning valley residents to “drink plenty of fluids, stay in an air-conditioned room, stay out of the sun and check up on relatives and neighbors. Do not leave young children and pets in unattended vehicles. Car interiors will reach lethal temperatures in a matter of minutes.”
Clark County has activated cooling stations for today and Saturday during daytime hours for all members of the public, including those experiencing homelessness. For the full list of cooling stations, visit helphopehome.org/get-help.

Then the temperatures soared. On May 11, parts of the valley saw 99 degrees. Then the temperatures dipped again. Strong winds and a few showers invaded the region, affecting the Electric Daisy Carnival.
