National Weather Service (NWS) meteorologists in Montana upgraded a winter storm watch to a winter storm warning for thousands of people on Friday and warned of hypothermia and dangerous, and at times impossible, travel conditions.
Why It Matters
Earlier this week, the NWS office in Missoula, Montana, issued a winter storm watch in advance of a winter storm set to arrive this weekend. On Friday, the watch was upgraded to a warning, which is a more severe classification. It is the first winter storm of the season, enhancing the need for advanced weather alerts and proper preparedness.
The storm comes during a time of year where hunters frequently visit Montana and Wyoming.
“The main concern is people being unprepared for the conditions out there,” NWS meteorologist Adam Dziewaltowski told Newsweek.
What To Know
The warning will go into effect at 12:01 a.m. Sunday and persist through noon. Heavy snow is likely at points above 5,500 feet in elevation.
As much as 8 inches of snow could fall, with NWS meteorologists warning of “major” winter weather impacts.
“15% chance for 10 inches of snow for elevations around Logan Pass,” the warning said. “Higher amounts for elevations above 7000 feet. Cold, wet, and windy conditions expected, with east northeast winds in excess of 30 mph will lead to concerns for hypothermia.”
The snow will affect Glacier National Park’s higher elevations, including Going-to-the-Sun Road and Logan Pass.
“For MAJOR winter weather impacts, expect considerable disruptions to normal activities. Dangerous or impossible traveling conditions,” the warning said. “Avoid travel in the impacted areas if possible. Widespread closures and disruptions to infrastructure may occur.”
The storm is severe enough for NWS meteorologists to urge people to consider delaying backpacking recreation trips if they had any set for this weekend.
Meanwhile, a winter weather advisory extends even farther south into Montana. A winter storm watch remains in place for Southern Montana and Northern Wyoming.
What People Are Saying
NWS Missoula in a winter weather advisory, which is less severe than a winter storm warning: “For MODERATE winter weather impacts, expect disruptions to normal activities. Hazardous traveling conditions. Use extra caution while driving. Closures and disruptions to infrastructure may occur.”
NWS Missoula in a winter storm warning: “If you must travel, keep an extra flashlight, food, and water in your vehicle in case of an emergency. The latest road conditions for the state you are calling from can be obtained by calling 511.”
What Happens Next
The warning will expire on Sunday. In the meantime, people are encouraged to avoid travel unless absolutely necessary. Outdoor enthusiasts are particularly at risk and should follow the guidance of local weather officials.
