Highlights

Dangerous avalanche conditions exist in the backcountry. Significant snowfall and strong winds have formed cohesive snow layers (slabs) that could easily be triggered by skiers in steep wind loaded terrain at the upper elevations. These slabs could be large, will increase in both sensitivity and size, and could release naturally as snowfall continues today. Cautious route finding and staying on lower angle slopes is the best way to avoid avalanche danger today.

    Strong winds have formed sensitive slabs on all elevations and on all aspects. These slabs could be triggered in steep terrain and will be largest and most sensitive at the upper elevations where they could be soft or hard and have depths to over 2 feet as accumulation continues.

Avalanche Discussion

All forecast regions have similar snowpack structure and avalanche concerns. New snow has fallen on a snowpack that was mostly stable two days ago. At that time recent warm temperatures had formed crusts on south facing slopes while snow surfaces on north facing terrain remained faceted. A combination of crusts and facets can be found on other aspects. New snow amounts vary by location. Snowfall over the last 24 hours favored the Teton and Togwotee ranges where approximately a foot of snow has fallen. In the southwest Trails area, less snow has fallen so far although significant accumulations are still possible today. Due to the very strong winds and rapid loading, wind slabs will be very sensitive in any steep terrain. In steep terrain at high elevations, slabs will be the most sensitive and it is likely that some natural activity occurred overnight. At mid and low elevations, although activity will be smaller in size and less sensitive, skiers and riders still have the potential to trigger avalanches, particularly in steep slopes loaded by the gusty winds. Temperatures remained colder at low elevations during the last week and  the widespread faceting that occurred there is well preserved. Remember that smaller events can still carry severe consequences. Avoid steep slopes and be aware of terrain traps.
