A large storm has hit the Bay Area, causing local schools to close preemptively.

The National Weather Service issued warnings for flash floods and high winds expected to last through Thursday. Power outages and fallen trees have been reported through the Bay Area.

Berkeley Unified School District offices and schools have closed and are expected to reopen Friday, according to the Berkeley Public Schools website. The Berkeley Public Library’s West Branch has also been closed due to power outages.

A fallen tree has blocked Euclid Avenue near Arch Street. Power outages were reported near near Alcatraz Avenue and Sacramento Street in South Berkeley. A downed power line caused a power outage in the Elmwood district around 5 a.m. Thursday morning, although power has since been restored in the area.

City of Berkeley staff are working to remove branches, clear storm drains and ward off flooding, according to a city press release.

In preparation for the storm, the city has been distributing sandbags for the past few days. Residents and merchants still needing sandbags can pick them up at the city’s corporation yard at 1326 Allston Way and at the Berkeley Marina, located at 200 Marina Blvd.

Pacific Gas and Electric is reporting electrical outages across the Bay Area, although due to storm conditions, there may be delays in updating estimated restoration times.
