LOS ANGELES (CBS) — A heat wave will bring triple-digit heat to some valley areas Monday at the start of a week likely to see a heightened danger of fire in the Southland, along with a risk of thunderstorms, forecasters said.
A high of 91, matching a record set on July 8, 2006, was recorded Sunday in Sandberg in the Antelope Valley. But no heat record is expected to be set today, and no thunderstorms are expected until later this week, likely Wednesday, said National Weather Service meteorologist Andrew Rorke.
The high temperatures forecast for this week — with triple-digit heat expected in both valley and mountain areas — will result from a strong upper-level high-pressure system centered over the great basin, according to an NWS advisory. The peak of the heat wave will be between today and Wednesday, it said.
Anyone planning to spend time outdoors early this week should stay hydrated and avoid strenuous activity, according to the weather service.
No red flag warnings were in effect early Monday, but “the hot temperatures combined with very low humidities will bring elevated fire weather concerns to interior portions of southwest California” through Monday, the advisory said.
Some monsoonal pressure is expected, which will result in a slight chance of afternoon and evening thunderstorms in the Antelope Valley and the mountains of Ventura and Los Angeles counties between Tuesday and Friday, according to the advisory.
The NWS forecast highs today of 71 in Avalon; 72 at LAX; 74 in Newport Beach; 84 in Long Beach and downtown L.A.; 86 on Mount Wilson; 87 in Anaheim; 91 in Burbank; 92 in San Gabriel; 94 in Pasadena; 100 in Woodland Hills; 101 in Saugus; and 103 in Palmdale and Lancaster. Temperatures will generally be a few degrees higher Tuesday and Wednesday before falling back to today’s levels.
