Los Angeles Braces for Another Week of Record-Breaking Heat

Los Angeles and surrounding areas are facing a prolonged heat wave stretching from Tuesday through Friday, with forecasters warning of a high risk of heat-related illness and the potential for numerous daily record temperatures to be broken. The National Weather Service predicts this will likely be the hottest week of the year for much of Southern California.

Extreme Heat Warnings Expected

Downtown Los Angeles is currently experiencing highs of 96 to 98 degrees, with forecasts predicting temperatures of 96 to 98 through Friday, and 94 on Saturday. Extreme heat warnings could be issued across the region between Sunday and Wednesday. The San Fernando Valley faces a 30% to 40% chance of reaching 110 degrees, while downtown Los Angeles has a 50-50 chance of hitting 100 degrees.

Valley and Coastal Temperatures

Valley residents can expect temperatures between 100 and 110 degrees, while coastal areas will see highs between 80 and 90. Meteorologist Ryan Kittell of the National Weather Service in Oxnard stated, "For much of L.A., this will likely be the hottest week of the year."

Death Valley Forecast

Death Valley is projected to reach temperatures of 119 to 120 degrees through Friday, with overnight lows in the mid-90s. A traveler from France died in Death Valley National Park on August 17th after his car broke down due to the extreme heat.

Causes and Risks

The heat is attributed to high pressure aloft and shifting northerly winds, leading to "compressional warming." While not Santa Ana winds, the weather service cautions of a history of large fires during periods of extreme heat. Authorities advise drinking plenty of fluids, staying in air-conditioned spaces, avoiding direct sunlight, and checking on vulnerable individuals. A heat advisory is currently in effect for downtown Los Angeles through 10 a.m. Tuesday.
