The National Weather Service has issued Winter Weather Advisories for two zones within Glacier National Park in northwestern Montana, warning outdoor recreationalists of wet snow accumulations up to 6 inches and wind gusts forecast to exceed 60 mph at the highest park elevations. Both alerts take effect at midnight Wednesday night.
Two advisories cover the West Glacier Region and the East Glacier Park Region. The West Glacier advisory remains in effect through 3 p.m. MDT Thursday; the East Glacier Park Region advisory lifts at noon MDT Thursday — giving visitors and backcountry users a roughly 12-to-15-hour window of hazardous conditions.
Snow and Wind by Zone
In the West Glacier Region, the National Weather Service is calling for wet snow above 5,000 feet, with total accumulations of 2 to 5 inches and wind gusts reaching 50 mph. The agency specifically warns that those gusts could bring down tree branches, adding a hazard beyond the snow accumulations themselves.
Conditions are more intense in the East Glacier Park Region. Logan Pass and other terrain above 5,500 feet could see 2 to 6 inches of snow, with gusts exceeding 60 mph at times. The National Weather Service characterizes conditions there as “dangerous for outdoor recreation and other activities.”
Road and Backcountry Impacts
Slushy snowfall is expected to affect park roads in both zones. Cold temperatures during the advisory window create a risk of hypothermia, according to the National Weather Service, for anyone outdoors without adequate winter gear.
Backcountry hikers, campers, and high-elevation day visitors should treat this advisory as a full winter weather event. The National Weather Service advises being “prepared for dangerous winter conditions” before entering the park’s backcountry during the advisory period. Road users heading toward higher elevations within the park should check conditions before departure.
Scope and Outlook
The advisories are geographically concentrated within Glacier National Park’s boundaries — the advisory data does not indicate broader statewide Montana impacts. Still, within those boundaries, the combination of accumulating wet snow, downed-branch risk, and gusts exceeding 60 mph at elevation makes this a significant event for anyone in the park’s high country overnight Wednesday into Thursday.
Conditions are expected to improve after the advisories expire — noon MDT for the East Glacier Park Region, 3 p.m. MDT for the West Glacier Region. The National Weather Service urges anyone planning backcountry travel to carry cold-weather gear and be fully prepared for winter conditions throughout the advisory window.
