Another powerful storm system is expected to sweep across a wide swath of the United States, bringing heavy rain to Southern California, heavy snow to parts of the West and Midwest and more snow and freezing rain to the Northeast and New England.

A winter storm headed for Vermont on Saturday and Sunday could drop as much as 10 inches of snow across the state, during one of the biggest weekends of the year for ski areas.

Heavy snow and freezing rain is slamming the Plains and Midwest, while the West Coast braces for severe thunderstorms that could bring flash flooding.
