GALLATIN VALLEY – Residents of Gallatin Valley should prepare for a Winter Storm Warning issued by the National Weather Service (NWS) Great Falls MT, effective from Sunday, October 11, at 6 PM MDT until Monday, October 12, at 9 AM MDT. This warning anticipates heavy, wet snow accumulations between 4 and 8 inches.

Before the Winter Storm Warning, a Winter Weather Advisory is in effect until Sunday, October 11, at 6 PM MDT, with up to two inches of wet snow and wind gusts as high as 40 mph.

Impacts include potentially very difficult travel conditions. Gusty winds combined with the heavy, wet snow may bring down tree branches, and isolated power outages are possible. The NWS advises that these hazardous conditions will affect the Monday morning commute.

If travel is essential, keep an extra flashlight, food, and water in your vehicle in case of an emergency. For the latest road conditions, call 511.
