September 23, 2019 – Red Flag Warning in effect across portions of interior Northern California today into Wednesday for gusty wind and low humidity..
Building high pressure will result in gusty north to east wind developing today and persisting into Wednesday. Combined with warming temperatures and lowering humidity, this will result in critical fire weather conditions across portions of Interior Northern California.
WIND: North wind 10 to 25 mph with local gusts 30 to 40 mph.
HUMIDITY: Daytime humidity in the 10 to 20 percent range with poor overnight recoveries of 30 to 40 percent, locally lower.
HIGHEST THREAT: Western portions of the Sacramento Valley, and adjacent foothills, where highest wind gusts and lowest humidity are expected.
IMPACTS: Any fires that develop will likely spread rapidly. Outdoor burning is not recommended.
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 can contribute to extreme fire behavior.
