2008 New Years Storms

A stormy and turbulent weather pattern helped ring in the New Year as an unprecedented storm impacted much of the West Coast. A series of storm systems moved through the San Francisco and Monterey Bay areas beginning January 3rd and ending January 6th. The strongest storm made landfall on January 4th and happened to be one of the strongest storms in the last ten years. All kinds of weather was observed during this period including wind gusts in excess of 100 mph that brought trees and powerlines down, flooding due to heavy rainfall, high surf at the coast and even snow over the higher peaks. Below is a sampling of some of the weather that was observed.
