In sintesi

Generally safe avalanche conditions exist. Remember that “Low” danger does not mean no danger. Small avalanches in isolated pockets of steep, wind-loaded terrain could catch you off guard.

    Winds over the past 72 hours have been strong at times out of the NW, W, and SW. Thin wind slabs up to 6 inches exist in isolated pockets of very exposed lee terrain at upper elevations. These wind slabs are becoming more stubborn and harder to trigger. Any resulting avalanche will be small, but getting knocked off your feet by a small avalanche in consequential terrain remains a possibility. Continue to look for drifts and pillows around the top of steep couloirs, near cliffs, and along ridgelines.  

    Yesterday, a large avalanche was observed in heavily wind-loaded, steep, rocky terrain. It probably slid 2 or 3 days ago, but it is a good reminder of this problem and where it is most likely to be found.

     

     

    (1/21/2025)

    A large repeat avalanche in the St. Patrick's Day Couloir that occurred sometime late 1/20 or early 1/21. The center chute slid on 1/8 .  Likely triggered by top/cross loading from strong winds of varying direction out of the north and west.

Avalanche Discussion

We currently have a generally stable snowpack with the possibility of triggering a small windslab avalanche in the alpine. As you step into more consequential terrain, remember that the hazard of getting knocked off your feet carries a high consequence around cliffs and steep couloirs, regardless of the avalanche size.

Moving forward, I’m thinking about what comes next in the Tetons. More than anything else, I am more concerned with weak snow near the surface (crusts and near-surface facets) that has developed over the last 2 weeks. The current surface is ripe to produce avalanches when it becomes buried. The incoming cold front tomorrow is forecasted to bring 4-6 inches of snow to the mountains - keep this in mind, as we will most likely see some surface instabilities in the next couple of days.

Please continue to send in observations - even a picture texted to 307-264-3050 can be very helpful!
