A powerful winter storm is set to blast portions of the U.S. with heavy snow, cold temperatures, strong winds and rain just as millions of people across the country prepare to travel for Thanksgiving.

A late November storm is set to bring a variety of impacts, including severe weather, accumulating snow, high winds and the first real blast of wintry-like temperatures this season, which could threaten travel at the start of Thanksgiving week.

Multiple winter storm warnings have been issued across five different states, with some advising people avoid travel. Different parts of Oregon, Washington, Idaho, Wyoming and Montana are under winter storm warnings with heavy snow expected across all these states.
