After a summer of record heat and California’s worst fire season in history, Santa Ana winds have repeatedly buffeted the Southland during a critically dry autumn. Will this warm, dry weather pattern finally come to an end, or will it continue through the winter?
Santa Ana winds will return amid dry conditions this week, significantly raising the risk of wildfires in the San Diego County mountains and western valleys, according to the National Weather Service.
Moderate strength winds were expected Tuesday in the mountains, forecasters said. Winds out of the east were expected to be around 15 mph, with gusts potentially reaching 30 mph Tuesday afternoon.
The autumn equinox was at 6:30 a.m. PDT on Tuesday, meaning there are nearly equal periods of daylight and darkness. From now until the winter solstice in December, days will gradually get shorter and nights will get longer in the Northern Hemisphere.
New wildfires ravaged bone-dry California during a scorching Labor Day weekend that saw a dramatic airlift of more than 200 people trapped by flames and ended with the state’s largest utility turning off power to 172,000 customers to try to prevent its power lines and other equipment from sparking more fires.
Strong Santa Ana winds — weather that rarely occurs in June — sent temperatures soaring more than 20 degrees above normal Tuesday across San Diego County, smashing or tying records from the coast to the foothills.
“The numbers were amazing,” said Mark Moede, a forecaster at the National Weather Service.
San Diego International Airport hit 93 degrees, which is 24 degrees above normal. Chula Vista reached 92 and Encinitas hit 90.
The Valley Center Municipal Water District’s investments over the years in independent power sources paid off this week when parts of the district were cut off by San Diego Gas & Electric implementing its shutoff protocols, but all of VCMWD’s facilities stayed powered—although four large (70 kw to 400 Kw) portable power had to be brought in to power five pump stations. This involved placing one of the 150 KW units between two pump stations as needed.
“And with those investments, water/wastewater service was sustained throughout the District service area,” concluded VCMWD Gen. Mgr. Gary Arant.
