On Friday, Dec. 12, the National Weather Service issued additional winter storm warnings and advisories affecting 19 states across the U.S. It has been an active week for the agency, as winter systems have delivered record snowfall to several parts of the country.
The NWS announced winter storm warnings, watches, and advisories for 19 states and Washington, D.C., spanning the Rockies, Midwest, Great Lakes, Northeast, and mid-Atlantic regions.
These alerts affect millions of Americans heading into the second weekend of December, with hazardous winter conditions complicating travel and holiday plans.
Which States Are Under New Winter Storm Warnings
According to the National Weather Service, a winter storm warning means heavy snow of at least six inches in 12 hours or eight inches in 24 hours is expected. This differs from a watch, which is issued at least 24 hours in advance and signals an increased risk of severe winter weather, though the timing, location, or impact may still be uncertain.
The new winter storm warnings issued Friday, Dec. 12, include Alaska, Kentucky, Indiana, and Montana. Winter storm watches are in effect for Alaska, Maryland, New York, Ohio, Pennsylvania, and West Virginia. Advisories have also been issued for Alaska, Iowa, Michigan, Montana, Nebraska, North Dakota, South Dakota, Virginia, and West Virginia.
Alaska is expected to see the heaviest snowfall, with Hyder forecast to receive 20 to 30 inches through Monday, Dec. 15. Travel in that area is expected to be especially dangerous.
Where Fresh Snow Is Hitting the U.S.
While Alaska is accustomed to heavy snow, other regions less familiar with winter conditions are also being affected. Indiana and central and northern Kentucky reported three to five inches of snow early Friday, Dec. 12, impacting the morning commute.
In Montana, heavy snow is expected through Friday night, with an additional four to seven inches possible. Iowa, Michigan, Nebraska, North Dakota, South Dakota, Virginia, and West Virginia are also forecast to receive more snowfall on top of the several inches already recorded earlier in the week.
When temperatures drop, staying indoors is recommended. For those who must go outside, proper clothing is essential. “Keep your nose, ears, cheeks, chin, fingers, and toes covered in warm, dry clothing,” the American Red Cross advises. “These areas are the first to be at risk for frostbite.”
