DENVER, COLORADO – A potent winter storm is expected to blanket much of Colorado’s mountains with significant snowfall this week, with totals reaching up to three feet in some areas. The storm, fueled by a strong atmospheric river, will begin in earnest late Monday and persist through Wednesday evening, bringing widespread travel disruptions during one of the busiest travel weeks of the year.
The National Weather Service (NWS) has issued Winter Storm Watches for much of Colorado’s high country, with forecasts calling for accumulations ranging from 12 to 36 inches in favored mountain areas, including Vail, Aspen, Telluride, and the central and northern mountain ranges.
According to NWS Grand Junction’s snowfall map, the heaviest snow is projected for the central mountains near Aspen and Vail, where totals could range from 14 to 21 inches. The San Juan Mountains near Telluride are also bracing for 12 to 21 inches.
