**Southwest Braces for Scorching Heatwave: Experts Warn Against Coffee Consumption**

Las Vegas, NV – A sweltering heatwave is poised to blanket Nevada and California this weekend, prompting urgent warnings from the National Weather Service (NWS) and local health officials. Temperatures are expected to climb into the triple digits, reaching potentially lethal levels in some areas, including Death Valley.

The NWS has issued an “Extreme Heat Warning” for desert regions of Nevada and southeastern California, effective from Friday morning through Saturday evening. Las Vegas, Pahrump, Barstow, and the Lake Mead Recreation Area are all under the warning. Temperatures in these areas are forecast to reach between 104 and 109 degrees Fahrenheit.

Further west, a heat advisory is in effect for a large swath of California, including the Sacramento Valley and central regions like Merced, Bakersfield, and Tulare. Temperatures in these areas are expected to hit the mid-to-high 100s.

“This will be the first heat wave of the season in the West,” AccuWeather meteorologist Heather Zehr told *Newsweek*.

Authorities are strongly advising residents to take precautions to avoid heat-related illnesses. The NWS is urging people to stay hydrated, seek air-conditioned environments, limit outdoor activities, and check on elderly neighbors and relatives. Perhaps surprisingly, one key piece of advice is to avoid coffee. The NWS warns that caffeine, along with alcohol, can accelerate dehydration.

“Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors,” the NWS said. “Do not leave young children and pets in unattended vehicles. Car interiors will reach lethal temperatures in a matter of minutes.”

Adding to the danger, the NWS Hanford (California) office cautioned about the deceptively cold temperatures of local lakes and rivers, which can create a dangerous temperature differential between air and water.

The heatwave is expected to peak on Saturday. Residents are urged to stay informed by visiting the NWS website for the latest updates.
