A powerful Pacific storm knocked out power to thousands across California and is threatening heavy mountain snow and flooding rain near the coast before it moves across the country.
The storm could churn tornadoes in the South and drop snow in the East by the end of the week.
Snow piled up in Washington, Oregon and California on Saturday, and an additional 2 feet could fall in the higher peaks of the Sierra Nevada range through Monday, the National Weather Service said. Southern California could get drenched Sunday with as much as 2 inches of heavy rain along the coast and valleys and 6 inches in the foothills.
