Santa Ana winds prompt red flag fire warning in L.A. County
The warning, which signifies critical brush-fire danger, is for inland and coastal mountain areas and the Santa Clarita Valley, where the dry northeasterly winds are expected to blow up to 40 mph.
The winds, coupled with low relative humidity, could result in explosive fire conditions, the Weather Service said. Light northeasterly winds were beginning to blow Thursday afternoon.
"Humidities have already fallen to between 10 and 15 percent across much of the region," the Weather Service said in a statement.
The winds will diminish by Saturday, but many areas will still experience low relative humidities, according the Weather Service.
