Fierce winds blew down trees and sent debris flying across the Bay Area overnight, causing traffic jams and scattered power outages across the region.
The National Weather Service recorded winds gusting more than 90 mph in some higher elevations in the North Bay and East Bay. Winds were strong throughout the Bay Area with many peak gusts above 40 or 50 mph.
Wind alerts continue through the morning.
"We are going to see winds begin to diminish throughout the day today but still be pretty breezy, especially in those higher elevations throughout the morning so don’t let your guard down quite yet this morning," said Roger Gass with the NWS. "By this afternoon, on the afternoon commute, conditions should be much better."
Gass said it is unusual to have a warm wind event with no rain at this time of year.
