High heat, low humidity, dry vegetation and gusty Santa Ana winds will combine to create an elevated danger of wildfire starting Saturday and lasting through Monday, forecasters said Friday.
But with temperatures up to 90 in downtown Los Angeles and into the 80s at local beaches, it’ll be a great time for a last chance to bask on the sand.
The National Weather Service said “the first offshore wind event of the season” would produce gusts of between 20 and 30 miles per hour Saturday and Sunday across interior sections of Los Angeles and Ventura counties. At the same time, humidity levels are forecast to dip to between 5 and 10 percent.
The Southland’s warmest locations are forecast to have highs of between 95 and 100 degrees Saturday and between 100 and 105 on Sunday.
“The combination of locally gusty offshore winds with hot temperatures, very low humidity and extremely dry fuels will bring an extended period of elevated fire danger this weekend,” according to an NWS statement.
“Critical fire weather conditions” are expected in the San Gabriel Mountains in Los Angeles and Ventura counties as well as in L.A. County’s Santa Clarita valleys, it said, urging people to exercise “extreme caution” when using power equipment outdoors. “If fire ignition occurs. rapid fire growth and extreme fire behavior will be possible.”
Late Monday or on Tuesday, moisture is expected to increase in the region as a result of an upper-level low-pressure system off the Baja California coast, NWS forecasters said. But the chance of thunderstorms developing as far north as Los Angeles County will be slight.
The NWS forecast a mix of sunny and partly cloudy skies in the Southland Friday and temperatures in Los Angeles County of 72 at LAX; 73 in Avalon; 77 in Long Beach and downtown L.A.; 80 in San Gabriel; 81 in Burbank and on Mount Wilson; 84 in Pasadena; 87 in Saugus; 89 in Woodland Hills; 91 in Palmdale; and 92 in Lancaster.
Temperatures are forecast to rise a few degrees Saturday, then climb sharply Sunday before beginning a progressive retreat Monday. Downtown L.A., for example, will have highs of 77 Friday, 82 Saturday, 90 Sunday and 88 Monday. On the same days, Woodland Hills will have highs of 89, 98, 104 and 101.
Friday’s Orange County highs were forecast to be 72 in San Clemente and Newport Beach; 75 in Laguna Beach; 77 in Anaheim; 78 in Irvine and Mission Viejo; 79 in Fullerton; and 81 in Yorba Linda. Yorba Linda, one of Orange County’s warmest communities, will be at 81 Friday, 87 Saturday, 94 Sunday, and 91 Monday.
By Thursday, Southland highs generally will be back to Friday’s levels.
