Another Red Flag Warning issued
The National Weather Service has issued a new Red Flag Warning in effect for San Diego County today, Tuesday, Sept. 8, from noon until Wednesday, Sept. 9 at 8 p.m. Expect strong gusty winds and low humidity.
A Red Flag Warning means that critical fire weather conditions are either occurring now or will shortly. Following several days of extreme heat, the threat of wildfires is extremely high, especially when combined with the high winds. Any brush fire could spread quickly in the next 24 hours. The Valley Fire, which began on Saturday afternoon, continues to burn south of Alpine and had consumed 17,345 acres as of Tuesday morning.
Expect east to northeast winds 20 to 30 mph with gusts to 45 mph, and gusts up to 55 mph possible in the windiest locations. The lowest daytime humidity will be 5 to 10 percent with poor recovery tonight, according to the National Weather Service.
Strong winds will begin first in San Bernardino and Orange counties, then spread southward this afternoon and into San Diego County late this afternoon and tonight. Winds will weaken for Thursday into the weekend with higher coastal humidity spreading gradually inland for Thursday into the weekend.
The National Weather Service in San Diego previously issued a Red Flag Warning that went into effect over the Labor Day Weekend.
