That giant heat wave baking the eastern 80 percent of the United States is moving west, into the deserts, mountains and valleys of Southern California, National Weather Service forecasters said today.
“The high pressure that’s causing the heat back across the Midwest and the East is migrating westward, so we are looking at our temperatures warming up over the next few days, especially across the inland area,” said Cynthia Palmer, forecaster at the NWS San Diego station.
Hot weather and triple-digit temperatures were expected early this week for most of San Diego County.
The National Weather Service predicted temperatures of 5-10 degrees above average Monday through Wednesday in deserts, mountains, and valleys.
High temperatures were expected to reach up to 120 degrees in lower deserts, 110 in upper deserts and 105 in inland valleys. Mountain areas lower than 6,000 feet could expect highs between 90 and 100 degrees and areas higher than 6,000 feet could have temperatures between 75 and 90 degrees.
The weather could turn deadly for unprepared campers or hikers, NWS forecasters said.
The meteorologists advised those who have to be outside in the heat to drink plenty of non-alcoholic, non-caffeinated beverages and to avoid strenuous outdoor activities if possible. While outside, wear lightweight, loose-fitting clothing and a hat and use sunscreen.
Never leave children or pets in an enclosed vehicle, even briefly, and take advantage of air conditioning and shade if possible, the NWS scientists urged.
