The storm hit Tuesday in Northern California, then swept through the central portions before bringing rainfall to Southern California by midmorning on Wednesday.

A live web cam at China Peak in the central Sierra Nevada showed snow accumulation on the slopes. Squaw Valley USA reported eight inches of new snow overnight, with up to nine more predicted by Thursday. The snow forced the closing of the 9,300-foot Tioga Pass through Yosemite National Park.

"It is an early winter storm. It is not unheard of to have one this early," said Cindy Bean, a meteorologist with the National Weather Service in Hanford.

The storm was especially painful to California's agriculture industry.

Leading up to the deluge, alfalfa growers worked to bale late cuttings, and cotton growers were scrambling to harvest before the storm hit. Rain can soak bolls and cause the cotton to fall out, making it unusable.

Wine grape growers, who are in the midst of harvest, generally did not expect the rain to be as much of a problem as it would have been if it had come earlier, when mold can develop. In Napa County, only cabernet sauvignon remains in the fields, and its thick skin serves as a protection, growers said. On the Central Coast, growers in the midst of harvest said the rain would serve to wash the dust from the grapes, but likely would not cause damage.
