The Excessive Heat Warning issued by the National Weather Service over the weekend continues through Wednesday evening as temperatures continue to soar in the Southwest United States.

All areas below 4,000 feet for portions of southern Nevada including Mesquite and the Moapa Valley, southeast California and northwest Arizona are included in the Warning.

Temperatures in Mesquite, Las Vegas, and much of the Mojave Desert region will range from 110 to 112 through Wednesday. Areas along the Colorado River valley will soar between 112 to 117 degrees while areas in the Death Valley region will hit between 120 and 125.

Nighttime temps will dip only into the 80s or 90s.

Relief from the very hot conditions is not expected until Thursday.

People most vulnerable to the heat include people working or recreating outdoors, people congregating in outdoor areas with poor ventilation or people without air conditioning. Pets confined in outdoor areas without shade and lots of water are also vulnerable to the heat.

The NWS warned that heat exhaustion and heat stroke will be possible during the warning period. Hot temperatures will create dangerous situations in which heat-related illnesses are possible. Drink plenty of water, stay in an air-conditioned room, stay out of the sun and check up on relatives and neighbors, the NWS advised.
