A wind advisory has been issued for 2 p.m. Saturday through 2 a.m. Sunday, bringing gusts of up to 40 to 50 mph. There's a possibility that winds could down trees and powerlines.
One of the biggest issues from Friday's storm was power outages that affected more than 20,000 customers, mostly in the East Bay.
In Point Richmond, overnight rains led to a spark that blew a transformer, followed by an explosion and then a fire that burned through the top portion of a power pole. The whole episode knocked out power to dozens of homes and businesses.

Contra Costa College in San Pablo also had a power outage, prompting the cancellation of classes for the day.
Also in the East Bay, there were two single car accidents just after noon on Highway 24 in Orinda. The CHP said no one was injured, but they were asking drivers to be extra careful and slow down.
The North Bay had its share of issues from the rain Friday morning. There were no landslides, but some car accidents. In San Rafael, an overturned big rig blocked traffic for hours.

BART suffered major delays Friday morning as the storm hit the Peninsula. A power outage caused BART to lose control of its track system around the Daly City station. Crews had to manually switch cars for most of the morning, which means they had to slow down, causing delays of up to an hour for passengers heading south of Daly City. Delays of up to 10 minutes continued through most of the morning.
