A third day of an atmospheric river storm has inundated Northern California and the Bay Area, with the storm spreading from the North Bay south across the region, flooding creeks, roads, and low-lying areas.

One of the strongest storms on the West Coast in decades knocked out power for thousands of people, unleashed strong winds that toppled trees and left two dead in Washington before making its way through Oregon to Northern California where on Thursday it dropped heavy snow and record amounts of rain.
