Summary
A significant winter storm is expected to bring up to 20 inches of snow to parts of the U.S. Southwest, particularly in Utah, later this week. The National Weather Service has issued a winter storm watch for several mountain areas, with a potential upgrade to a warning as the storm progresses. Heavy snow is likely to affect travel on mountain routes, and precautions are advised due to possible avalanche risk and traction requirements.
