Drivers heading into the Absaroka and Beartooth Mountains should prepare for early-season winter driving conditions, as a winter weather advisory takes effect tonight. The National Weather Service (NWS) office in Billings has issued the alert from 6 p.m. Monday, September 15, through midnight Tuesday, September 16, warning that light snow could create slick and hazardous conditions at higher elevations.
Forecasters expect 1 to 3 inches of snowfall above 10,000 feet, particularly along the Beartooth Highway, one of the region’s most scenic and well-traveled mountain routes. While the amount of snow is relatively modest, officials caution that even light accumulations can quickly make mountain passes icy and treacherous.
The Beartooth Highway, which links Red Lodge, Montana, to the northeast entrance of Yellowstone National Park, is known for its steep climbs, sharp curves, and sweeping views. Its high elevation also makes it prone to early fall snow events, catching some travelers off guard. “Conditions can change rapidly at altitude,” the NWS noted, “and drivers should be prepared for winter weather even when valleys remain dry.”
Motorists planning trips across the highway are advised to slow down, allow extra travel time, and exercise caution on snow-covered stretches. Reduced traction, combined with winding mountain roads, increases the likelihood of accidents when drivers fail to adjust for conditions.
The Montana Department of Transportation (MDT) also reminds drivers that road conditions can shift quickly with changing mountain weather. Updated reports are available by calling 511 or checking MDT’s travel information website. Chains and winter tires are not currently required, but carrying emergency supplies is strongly recommended for anyone traveling at higher elevations.
Officials also warn that temperatures will drop sharply overnight in the mountains, which could lead to refreezing of slush or wet spots by morning. Hikers, campers, and park visitors should be prepared for colder conditions, even if weather at lower elevations remains mild.
While the advisory is set to expire Tuesday night, forecasters stress that September often marks the start of unpredictable mountain weather across Montana. Travelers are encouraged to monitor forecasts closely and adjust plans if conditions worsen.
For now, anyone venturing along the Beartooth Highway should expect wintry travel, drive cautiously, and prepare for sudden shifts in both weather and road conditions.
