Forecasters in the US have warned of another round of winter weather that could complicate travel leading up to Thanksgiving.

Santa Rosa, California, saw its wettest three-day period on record with about 32 centimeters of rain falling by Friday evening, according to the National Weather Service in the Bay Area. On Saturday vineyards in Windsor, about 16 kilometers to the north, were flooded.

For those looking to get a head start on travel over the weekend, much of the U.S. will be dry, except for the West Coast and Northeast. From California to the Pacific Northwest, rain and mountain snow will extend eastward into the Rockies, according to Weather.com.

Thousands in the Pacific Northwest remained without power after multiple days in the dark. The National Weather Service office in Sacramento, California, issued a winter storm warning for the state's Sierra Nevada for Saturday through Tuesday, with heavy snow expected at higher elevations and wind gusts potentially reaching 55 mph (88 kph).

Across the U.S. major storms are dumping snow and rain, with another system expected to arrive for Thanksgiving.

A major storm dropped more snow and record rain in California, causing small landslides and flooding some streets, while on the opposite side of the country blizzard or winter storm warnings were in effect Saturday for areas spanning from the Northeast to central Appalachia.
