An atmospheric river has begun to slam California that is expected to bring days of heavy rain, strong wind gusts and potentially feet of mountain snow to the Golden State through early next week, ushering in the region’s rainy season.

The storm system is forecast to bring several months’ worth of rain to Southern California in the span of just a few days.

A dangerous situation will unfold on Saturday as the peak of the ongoing rain event takes center stage.

According to the FOX Weather Center, the peak will continue between the hours of 4am-12pm PT. During the peak, rain rates up to one inch per hour are possible, with a chance of thunderstorms and even a weak tornado.

As a result, a flash flood threat level 3 out of 4 now exists through Sunday morning across California.
