SoCal’s atmospheric river storm this week: How long will it last and what areas will get the most rain?

An atmospheric river is expected to bring heavy rains to Southern California, starting Thursday and continuing until Sunday.

A fast-moving atmospheric river is barreling toward Southern California this week and could bring heavy rain, and with it, a risk of flooding and debris flows in recently burned areas.

The expected rainfall could also help lower the risk of a deadly fire season in the region this year.

The storm is expected to arrive in Northern California on Wednesday and reach Southern California on Thursday, according to the National Weather Service. The system could produce the most rain downtown Los Angeles has seen in at least a month, and possibly since February.
