26 July 2018

The weather service says other record highs set Tuesday included 122 (50 Celsius) in Thermal, in California's Coachella Valley, and 121 (49.4 Celsius) in Palm Springs.

Nothing has changed in the excessive heat warning issued this week by the National Weather Service as temperatures remain around 105 degrees today, dropping by just a degree Thursday.

An excessive heat warning from the National Weather Service in Las Vegas is in effect through Thursday, when temperatures are expected to reach 114 degrees (45.5 Celsius).

On Wednesday, meteorologists said Palm Springs could reach 119 degrees and Riverside 107 degrees, tying records from 1943.

High temperatures this month have played a role in the deaths of four people, according to county public health officials. By mid-week, monsoonal moisture will move back into the area and drop temperatures.

"Today will be the worst of the heat as temperatures decrease tomorrow", the U.S. National Weather Service Austin-San Antonio Texas said in a Facebook post.

The weather agency uses a complicated formula that varies from region to region to declare an excessive heat warning, including close to record or record-breaking temperatures.

California's power grid operators called for cutbacks in electricity usage as parts of the U.S. Southwest braced Tuesday for another day of scorching heat.

Authorities urge the public to avoid potential health hazards by drinking plenty of water or other non-alcoholic fluids, seeking out shady and/or air-conditioned environments and checking up on relatives and neighbors - - particularly the elderly or home-bound people - to ensure that they are handling the heat all right.

In addition, young children and pets should never be left unattended in vehicles during hot weather, when auto interiors can reach lethal temperatures in a matter of minutes, officials warn.

With some of the highest Southwest temperatures over the next few days expected in Phoenix, officials cautioned people to stay hydrated and take advantage of cooler indoor buildings.
