A powerful storm swept through all of California with high winds, periods of heavy rain, and locally heavy snow. Strong upslope flow off the Pacific and a high freezing level fueled larged amounts of rainfall on the coastal slopes. The snow level fell late in the storm as colder air filtered in resulting in heavy snowfall at elevations above 6000 feet. Isolated flash flooding and debris flows were reported, mainly in the burn areas. Flash flooding in the Inland Empire resulted in one death.
