A weak atmospheric river is brewing over California and is set to deliver two rounds of moderate to heavy rainfall, a chance of thunderstorms and small hail.

Rain pelted the Bay Area again Friday morning as the most intense part of the second wave in a storm pattern whipped its way onto shore accompanied by cold, gusty winds similar to those that blew during the first round.

A pair of relatively weak atmospheric river storm systems will sweep over the Bay Area this week, bringing rain to the Central and North Coasts as well, according to the National Weather Service.

The Bay Area’s latest storm system delivered a powerful mix of heavy winds, scattered thunderstorms and steady rainfall. Though flooding wasn’t reported Wednesday, the gusts were strong enough to knock out power.

Heavy rain is expected to make its way back to the Bay Area on Friday after a storm system raged across the region on Wednesday.
