Residents in Southern California's low deserts should brace for scorching weather, as the National Weather Service (NWS) in San Diego has issued an Excessive Heat Warning for the area beginning this Friday. According to the National Weather Service, Dangerous temperatures of up to 114 will be possible in these areas, with temperatures over 110 being common. This extreme heat is expected to persist into the early parts of next week, potentially affecting the Coachella Valley and San Diego County Deserts. NWS cautions that these conditions may increase the risk of heat-related illnesses.
The heat will to gradually intensify through Saturday, affecting not just the deserts, but also bringing higher temperatures for the coast and valleys. Friday is anticipated to be notably warmer than Thursday, with high temperatures for the coast and valleys ranging from around 70 near the beach to the mid-80s to mid-90s for the inland valleys. Warnings suggest the situation could become even more precarious in the lower deserts, with temperatures slated to hit between 107 to 113 degrees.
The NWS further indicates that under these increasingly oppressive conditions, coastal low clouds in the morning will spread intermittently into parts of the western valleys each night. This weekend, some desert locales may even challenge or match historical temperature records. Palm Springs tied the existing record high temperature of 114, set in 1947, underscoring the severity of the current heatwave.
In the immediate term, no hazardous marine conditions have been forecasted through Monday. The NWS advises that Skywarn activation is not required at this time, yet they encourage weather spotters to report significant conditions. With the Excessive Heat Warning in effect from 10 AM Friday to 8 PM PDT Saturday, it's crucial for residents in the warned areas to take preventive measures to ensure safety under these extreme temperatures.
