- Beartooth pass closed today due to “blowing and drifting” snow and “black ice”
A second winter weather system is moving into the northern rockies today and areas of Montana, Idaho, and Wyoming could see anywhere between 10″-24″ by Saturday morning reports NOAA.
Montana skiers are already making turns and this second storm might allow Wyoming and Idaho residents to join the powder party. Right now, the storm’s focus seems to be on Cooke City.
“Mountain snow will be an issue for the next several days. Another frontal system moves in on Thursday and will bring more widespread mountain snow and rain showers.” – NWS Riverton, Wyoming
Look for the Tetons and Gros Ventre ranges in Wyoming to also see significant snowfall. As far as Idaho is concerned, models are showing that the areas northeast of Sun Valley should see the biggest accumulations.
