Highlights

The avalanche danger is Considerable at the mid and upper elevations today. New snow and wind has formed slabs that will be sensitive to human triggers and may release naturally. In steep wind loaded terrain it will be important to be on the lookout for obvious signs of unstable snow such as avalanches, shooting cracks and whoompfing. In the low elevations the danger will be Moderate, where it will be possible to trigger shallow avalanches in very steep terrain in areas that had snow on the ground prior to this recent storm. **Special Statement**Grand Targhee Resort will be closed to all uphill traffic until Thursday April 14th, as the resort performs end of season operations.

    New snow amounts over the last 48 hours range from 12-24”. Winds have come from a wide variety of directions during this storm. As a result it will be possible to encounter loading in unusual spots. Slab depths will range from 1 to 3 feet. Involvement in an avalanche today will have serious consequences due to the potential high volume of snow. Use a conservative approach to terrain by avoiding steep wind loaded slopes.

    In very steep terrain loose snow avalanches will have the potential to gather enough volume to knock skiers and riders over and into terrain traps. If entering steep terrain expect snow that was not wind effected to move readily and run long distances.

Avalanche Discussion

Light to moderate snowfall will continue overnight as northwest flow brings moisture to the Tetons and Salts. Temperatures tomorrow will be similar to today, with overnight lows near zero before rising to the mid-teens. West winds will continue at 15-20 mph overnight and tomorrow. Another one to three inches of snow is likely by tomorrow morning with another one to three falling through the day tomorrow.Elevations above 8,000’ will continue to have the reactive wind and storm slabs that warrant a Considerable danger rating tomorrow. New snow will add more load and continue to build slabs. Human-triggering will remain likely in steep terrain. Middle and lower elevations will have less avalanche hazard due to less snow there. Expect Moderate danger at mid-elevations and low danger in areas below 7,500’ that lack the snowpack for slabs to develop upon.
