The Winter Weather Advisory highlights potential travel disruptions in Montana's mountain regions, particularly in the Centennial Mountains and Gallatin/Madison County Mountains. Snowfall of 2 to 5 inches combined with gusty winds up to 40 mph could create slick and hazardous conditions over mountain passes such as Raynolds Pass and Targhee Pass. Travelers should exercise caution, especially during the advisory period from 9 PM Monday to 6 AM Tuesday. Lower snow levels on Thursday may also impact areas near and north of US-2, with minor accumulations possible.
