Late-Season Snow to Impact the Northern Rockies

Keep those snow brushes handy! ❄️ We are tracking a shift to much cooler and wetter weather starting Wednesday night. While it’s April, Mother Nature has other plans for Western Montana and North-Central Idaho. 📍 Where: All mountain passes and most valley locations. ⏰ When: Wednesday night through Friday. The most "impactful" travel window for valleys looks to be Thursday morning. 🚗 Travel: If you've already swapped your winter tires, take extra caution on the passes! ⚠️Localized power outages/tree damage are also a concern due to heavy, wet snow. Check the latest pass conditions before you head out.
