The wider storm
A low pressure system moving in from the Gulf of Alaska and drawing in moisture from the tropics combined to bring the first atmospheric river event of the winter season to the Greater Bay Area. This system brought widespread heavy rainfall, roadway flooding, and strong winds to the region. Rare Storm Warnings were issued over the coastal waters where buoys reported wind gusts in excess of 50 mph. Bay Area peaks recorded wind gusts between 60 to 70 mph with gusts along the Monterey Peninsula and Big Sur Coast at 50 to 60 mph. These winds caused downed trees and power outages across the area.
Began near Carte Madera (37.9250, -122.5137).
