A weak storm system will impact Southwest California on Monday, and gusty north to northwest winds will develop as this system exits Monday night. Gusty winds will continue through Friday night, but the strongest winds will occur during each evening. Locations that will feel the greatest impacts include the Santa Barbara County South Coast and foothills, the I-5 Corridor through the LA and Ventura County Mountains, the Antelope Valley, and the coastal waters. The peak winds are expected to occur Wednesday and Thursday night, with winds gusting from 30 to 50 mph, with greatest potential over the hills near Montecito. Winds in this range will cause hazardous seas, as well as the potential for downed tree limbs and power lines and hazardous driving for high profile vehicles.
Moderate to strong Santa Ana winds, along with very dry air and fuels, will result in dangerous fire weather conditions Sunday night through Tuesday. Use extreme caution with any potential fire sources!
A moderate to strong Santa Ana wind event will create locally wind driven swells that will impact east facing on Monday. Short-period wind driven swells around 5 feet will affect northeast facing harbor entrances. These harbors should not be considered safe and should be avoided on Monday.
A very dry and cold air mass will settle over the area by Monday, and likely bring sub-freezing temperatures to the Antelope Valley. These conditions may result in crop and vegetation damage, and hypothermia danger to people and animals.
