Montana Snow Squall Triggers Whiteout, Travel Warning
25 Nov, 2025
Summary
- Over 2,500 people were warned about dangerous snow squall conditions.
- Whiteout conditions with near-zero visibility were reported.
- Travelers are urged to reduce speed and turn on headlights.
The National Weather Service issued an urgent warning to more than 2,500 residents in Jefferson County, Montana, on Monday afternoon as a dangerous snow squall caused whiteout conditions. This alert arrived as many Americans planned their Thanksgiving week travels, highlighting the critical need for immediate weather updates.
Snow squalls can descend rapidly, transforming clear skies into hazardous situations with near-zero visibility within moments. These storms are notorious for causing significant accidents, often triggered by drivers reacting suddenly to the unexpected wintry onslaught. The warning specified areas like Whitehall and Homestake Pass, including Interstate 90.
Meteorologists at the Great Falls office reported "whiteout conditions with near zero visibility associated with intense bursts of heavy snow and gusty winds." They advised, "Reduce speed and turn on headlights!" This event occurred while much of Montana was already under a winter weather advisory, with forecasts for several inches of snow and potential ice.
