More winter snow and rain pummeled the West on Thursday as the first in a series of expected storms soaked morning commuters in much of California, dumped 18 more inches of snow in the Sierra Nevada and closed schools in Oregon, AP reported. The first of three anticipated winter storms hit the Lake Tahoe area, with another 6 feet of snow possible by Monday in the upper elevations of the Sierra Nevada. Since Jan. 1, more than 15 feet of snow has fallen at some Tahoe area resorts, the most in more than five years.
