National Weather Service warns of potentially hottest week of the year in Southern California
Meteorologists predict a heat wave from Tuesday through Friday with temperatures reaching up to 110°F in valley areas and a high risk of heat-related illness.
The National Weather Service has issued a high-risk heat advisory for Southern California, forecasting the hottest week of the year from Tuesday to Friday. Temperatures in downtown Los Angeles are expected to stay between 96°F and 98°F through Friday, dropping slightly to 94°F on Saturday, while inland valleys could see highs of 100°F to 110°F. Coastal areas are projected to remain in the 80°F to 90°F range.
"For much of L.A., this will likely be the hottest week of the year," said Ryan Kittell, a meteorologist with the National Weather Service in Oxnard. "It will be warm Monday, then really crank up Tuesday. In the valleys, we’re looking at anything between 100 and 110. Along the coast, expect highs between 80 and 90, even in the beach areas."
The service advises residents to stay hydrated, remain in air-conditioned spaces when possible, limit sun exposure, check on vulnerable neighbors, and stay alert to fire hazards. An extreme heat watch is in effect from 10 a.m. Tuesday through 8 p.m. Friday, indicating conditions that could soon trigger an extreme heat warning.
Death Valley is expected to record temperatures of 119°F to 120°F, with overnight lows in the mid-90s. The heat is attributed to high-pressure systems that cause compressional warming, combined with a shift toward more northerly winds, which can further elevate temperatures.
