⚠️ WINTER TRAVEL ALERT ⚠️ A significant weather transition will be moving through the Northern Rockies from Noon Friday (Dec 26) through Saturday morning (Dec 27). This system will impact both western Montana and north central Idaho. Expect a rapid transition from wet roads to snow and ice. Bursts of heavy snow may briefly lower visibility to near zero, especially for travelers in the following areas: Idaho: Hwy 95 (Grangeville/White Bird), Hwy 12 (Orofino to Lolo Pass), Elk City, Dixie. Montana: I-90 (Lookout Pass to Butte), Highway 93 (Eureka to Lost Trail Pass), and Highway 2 (Troy to Marias Pass). Including: Missoula, Kalispell, Libby, Seeley Lake. Mountain Passes: Lookout, Lolo, Lost Trail, Marias, and White Bird Hill will likely see the most difficult driving conditions with periods of heavy snow. 🏔️❄️ Additionally, a passing cold front will bring wind gusts of 30 to 45 mph. If you are in an area still recovering from recent wind damage, please stay alert as these gusts could cause further issues. 🌬️ ✅ Check conditions before you head out. ✅ Slow down on slick surfaces. ✅ Stay safe!

A strong cold front will move from west to east across the Northern Rockies late Friday night into Saturday. Heavy snow, strong winds, and significantly reduced visibility with snow squalls and or snow bands along and behind the front pose a risk to travel across the region. If you need to travel during this time, make sure you have a way to receive emergency alerts or weather updates, and emergency supplies such as food, water, warm clothing, and proper winter outdoor gear. If you encounter a snow squall, get off the road and into a safe area such as a parking lot while waiting for the worst to pass. If you get into an accident, wait with/inside your car for shelter and warmth until emergency services can reach you.
