In some areas, up to 36 inches of snow could accumulate, with winds reaching speeds of up to 55 mph. The hazardous conditions are expected to significantly impact Thanksgiving travel, with reduced visibility and snow-covered roads making driving conditions treacherous.

Reduced visibility and heavy snow—up to 6 feet of snow accumulation in some parts—are forecast just days away from Thanksgiving. And the National Weather Service has issued warnings for 13 states: Colorado, California, Nevada, Utah, Wyoming, Vermont, Michigan, Alaska, New York, Idaho, Maine, New Hampshire and New Mexico.
