Time-lapse footage captured by an NBC Bay Area weather camera shows rain and wind as it moved across the San Francisco Bay on Friday afternoon.
Friday's storm is part of a second round of rain this week to dump down on the region. The storm sparked a barrage of trouble, including the death of a motorist in Oakland, the rescue of a person from "frigid" waters in a San Jose creek, widespread flooding and power outages.
The rain, which is much needed as California is suffering through a drought, is now also causing headaches for other parts of the state, too.
Mandatory evacuations were in effect for some of Los Angeles on Friday, as rain, snow and gusty winds brought threats of flooding and mudslides. At one point, a man and two dogs were rescued from the Los Angels River's rising flood waters.
And in San Diego, lifeguards were on alert because of high surf and high tide warnings, as rain brought as much as 10 inches in the mountains there.
The rain is expected to last through Saturday.
