Warning runs through Sunday evening
Last Updated: 64 days ago
SAN DIEGO - Strong gusty winds and low relative humidity coming to San Diego County this weekend has prompted the National Weather Service to issue a Red Flag Warning for most of the county that will take effect Friday morning.
The warning will go into effect 11 a.m. Friday and last until 8 p.m. Sunday for the county's inland valleys and mountains, according to the NWS. The Fire Weather Watch issued Tuesday has been replaced by this warning.
"A moderate strength Santa Ana wind event is shaping up for late Thursday night through the weekend," according to the National Weather Service. Sustained northeast to east winds of 25 to 40 miles per hour, with
gusts as high as 65 mph through and below canyons and passes, are expected.
"Winds will peak on Friday night and Saturday, then diminish Sunday," an NWS advisory said.
Relative humidity this weekend is expected to be mostly 5 to 15 percent, rising only a few hours each night to above 25 percent.
"A Red Flag Warning means that critical fire weather conditions are either occurring now or will shortly. A combination of strong winds, low relative humidity and warm temperatures will contribute to extreme fire behavior, " the advisory said.
