The worst of the storm isn't over yet, as the odds of thunderstorms and heavy rainfall continue to increase late Thursday into early Friday.
Santa Barbara, Ventura and western Los Angeles counties are going to be under the gun. The low pressure system is moving slowly over the area and could dump as much as 1 to 2 inches of rain per hour, raising the risk of flooding. A total of five additional inches could fall on our foothill and mountain areas. Short lived tornadoes are still possible.
Things should start to dry up on Saturday.

A flood watch (flooding may occur) is in effect throughout Santa Barbara, Ventura, Los Angeles, Orange, Riverside, San Bernardino and San Diego counties into Friday. Isolated pockets of intense rain will bring the greatest risk over the next 24 hours.
As is customary, please avoid the beach for at least 72 hours following heavy rains. An L.A. County beach advisory is in effect.
A bit of snow
By the time this storm starts to wrap up, most of the snow will have fallen above 7,500 feet, with higher peaks on mountains like San Jacinto in Riverside likely seeing around a foot.

Our hard-hitting watchdog reporting on local government, climate, and the ongoing housing and homelessness crisis is trustworthy, independent and freely accessible to everyone thanks to the support of readers like you.

Speaking frankly, the amount of reader support we receive will help determine how strong of a newsroom we are going forward to cover the important news in our community.
