Storm battering West Coast now moving east with further warnings

The storm which caused flooding in Washington now threatens the Midwest.

The storm system begins to move east from the Rockies into the central Plains and into the Great Lakes and East Coast this weekend.

Ahead of the storm, 10 western states are on storm alert for damaging winds, heavy snow and flooding rain.

The heaviest rain on Thursday morning is falling in California, around the San Francisco Bay area, and into the low elevations of Sierra Nevada mountains.

The heaviest snow this morning is falling in the Cascades and Sierra Nevada mountains.

Over the next 24 hours, the storm system will begin to move east, bringing heavy snow and wind to the Rockies. Some rain is even possible in Southern California around Santa Barbara and Los Angeles.

Behind the storm system, much colder air and gusty winds will produce heavy lake effect snow bands near the Great Lakes from Grand Rapids, Michigan to Buffalo, New York.
