Highlights

New snow and wind has created heightened avalanche conditions. Riders have the potential to trigger an avalanche on very steep, wind-loaded slopes today. Be on the lookout for signs of instability such as cracking and steer clear of steep, loaded terrain.

We will issue our last daily Avalanche Forecast of the season for this zone on Friday, April 10th. We will issue General Avalanche Information Bulletins as needed through early May and compile 24-Hour Snow and Weather Data (aka the Big Sheet) through June 1.

    Nearly a foot of new snow has fallen in the upper elevations in the past 24 hours. Wind speeds have increased this morning out of the northwest forming soft slabs up to 18 inches deep in wind-loaded, upper elevation terrain. Riders have a good chance of triggering one of these slabs today on very steep, loaded features. Watch for slab development below ridges, around cliffs, and in cross-loaded gullies. Slabs may be found on a variety of aspects given the shift in wind direction yesterday evening. Avalanches involving new snow could run farther and faster than expected on recently buried crusts. Cracking and blowing snow are signs of wind loading. Avoid steep terrain if you are observing these conditions. 

    Be prepared for loose snow sluffing in very steep, sheltered terrain given the impressive overnight snow totals. Loose snow avalanches may move quickly and entrain a significant amount of snow on buried crusts.

    Watch for fresh wind slabs in steep, exposed terrain below ridges and around cliffs.

Avalanche Discussion

Snowfall from the past three days of stormy weather should taper off today. Upper elevation storm totals for this period are sitting around 18 inches with about 1.5 inches of snow water equivalent (SWE). About half of that snow fell within the last 24 hours. Avalanches involving last night's snow will be the greatest concern today. Wind speeds have been strong enough to move snow and the direction shift from southwest to northwest loaded slopes on a variety of aspects.  Snow from previous days has now had some time to bond to underlying crusts. Avalanche activity yesterday was relatively minimal. Shallow slabs that were reactive to ski cuts were reported at JHMR. Mitigation work yesterday on Teton Pass did not produce any large avalanches. Carefully evaluate the new snow stability before committing to steeper terrain. If in doubt, default to lower angle terrain that is sheltered from the wind and enjoy the welcomed new snow!
