New Santa Ana winds threaten to spread wildfires
Another round of Santa Ana winds is forecast to sweep into Los Angeles on Thursday night into Friday morning, putting most of the region under a critical fire risk, as emergency responders battle to contain five quickly spreading wildfires.
The wind in the region relaxed overnight as the low pressure, which was helping enhance the wind, is moving away into Texas.
But high pressure is building from the north and that will help to tighten the pressure gradient over Southern California, producing more gusty winds.
Red flag and high wind warnings have been issued through Friday afternoon for wind gusts 40 to 60 mph, with 70 mph possible in the mountains.
Relative humidity could drop to as low as 5% for Southern California.
Because of the dry and windy conditions anticipated, a critical fire risk has been issued for much of the area for the next 24 hours.
