Get Ready For A Night Of Heavy Rain And Possible Flooding

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.
