Highlights

Clear skies overnight and near freezing temperatures have frozen snow surfaces, and mostly stable conditions exist in the early morning hours. Mountain temperatures are starting out around 10 degrees warmer than yesterday morning, and the general avalanche hazard will quickly rise to Considerable above 8,000 feet as crusts break down and snow surfaces become saturated. As this happens, dangerous avalanche conditions will develop, and naturally releasing wet loose slides and large to very large wet slabs will become likely. Get a very early start, be prepared for the rapid development of wet slides, and get off of and out from under avalanche prone terrain before conditions become unstable. While the snowpack below 8,000 feet has undergone numerous melt freeze cycles, wet slides may still be possible where the snowpack remains. The final morning avalanche hazard bulletin of the season will be issued on Sunday, April 21st.

    Yesterday, abundant sunshine and warm temperatures resulted in significant avalanche activity in the Tetons as the April snowfall was substantially heated for the first time. Temperatures will be warmer today, and large to very large wet slab avalanches will quickly become likely above 8,000 feet. These slabs could be one to three feet deep. Smaller wet loose slides will also become likely on very steep terrain features. These wet slides could travel long distances and may gouge down to the ground in areas where the snowpack is isothermal.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Skies will be mostly clear overnight and through the day on Friday. Overnight lows in the mountains will be in the mid-20s before climbing into the mid-40s in the afternoon. The valleys will drop to near freezing tonight before rising to near 60 during the day. Westerly ridgetop winds will back to the southwest at 10 to 20 miles per hour.Expect mostly stable conditions in the early morning hours after below freezing temperatures and clear skies form crusts overnight. The general avalanche hazard will quickly rise to Considerable above 7,500 feet as the crusts break down and snow surfaces become saturated. Once this happens, naturally releasing wet loose slides and large to very large wet slabs will become likely. Get a very early start, be prepared for a rapid increase in the wet snow avalanche hazard, and get off of and out from under avalanche prone terrain before conditions become unstable. While the snowpack below 7,500 feet has undergone numerous melt freeze cycles, wet slides will still be possible where the snowpack still exists.
