Santa Ana Winds
The arrival of Santa Ana winds coupled with very low relative humidity prompted the National Weather Service (NWS) to issue Red Flag Warnings for much of Los Angeles and Ventura counties.
Moderate to locally strong Santa Ana winds will continue across the mountains of Los Angeles and Ventura counties and associated coast and valley areas through Thursday afternoon. The offshore winds will strengthen into Thursday morning with gusts up to 40 – 45 mph.
Poor relative humidity recoveries are expected tonight with many locations remaining below 25 percent. On Thursday, conditions will continue to dry with areas of single digit relative humidities likely along with well above normal temperatures for most areas. Very dry conditions are likely to persist into Friday, but with much lighter winds.
A red flag warning remains in effect for much of Los Angeles and Ventura counties through Thursday due to the combination of moderate offshore winds, low humidities, warm temperatures, and abnormally dry fuels. —NWS
