In less than a week, Southern California’s weather has gone from unseasonably dry and warm – to wet and now bitterly cold. The National Weather Service says the same low pressure system that brought rain to the region last weekend is “still spinning” and producing overnight low temperatures in the 30s

The most serious red flag fire weather warning has been issued by the NWS for swaths of L.A. and Ventura counties starting before dawn Tuesday.

Southern California will continue to face "dangerous fire weather conditions" including strong Santa Ana winds and extremely low humidity through later this week, forecasters said Tuesday.
