In sintesi

Sun, warm temperatures, and a lack of freeze will maintain heightened avalanche danger. Don't linger on steep slopes with wet snow or under snow-covered rock features. While the chances of being caught in an avalanche on Friday aren't significant, large slabs of snow falling off rocks and cliffs could be big enough to kill you.

    Be aware of steep, overhead terrain. Don't linger under snow-covered cliffs, slabs of rocks, or other vertical features that could shed snow. Glide avalanches, cornices, and large chunks of snow can initiate avalanches and could be big enough to kill you on their own.

    Many rock features and slabs are still holding snow and could continue to shed with ongoing warm temperatures and sun. While the likelihood of glide avalanches are approaching unlikely, the consequences are are serious.

    Multiple avalanches (up to size D2) just outside the Stevens Pass Ski Area boundary above Lake Susan Jane. These likely occurred between the night of the 11th and the morning of the 13th. Some may have initiated due to glide or cornice releases. Lumiere Ridge, NE, 5,200-5,600ftWL-N-D2-O

Avalanche Discussion

Pay attention to surface conditions. If you sink into wet, unsupportive snow or see recent roller balls or wet avalanches, move to more shaded and lower-angle terrain. Don't linger under steep slopes where avalanches could come down from above.

On Thursday, sunny mid-elevation slopes softened, but the surface crust never fully melted. No new avalanches have been reported since the 13th. Clear skies and temperature inversions have allowed the snow surface to cool, but have also kept upper elevations hot. The prolonged lack of freezing temperatures raises concerns for another round of wet avalanches. 

Avalanche professionals and NWAC forecasters reported a widespread natural wet avalanche cycle on the 12-13th following 1.4" of rain that began on the 11th. Most avalanches were large, and some ran long distances, gouging through much of the recent storm snow. While many rock features released large chunks and glide avalanches, no crowns or slab avalanches were reported.

The January 3rd melt-freeze crust is 1.5-2 feet below the surface. Melt water also pooled at other interfaces in the upper snowpack. The continued warm temperatures raise concern for deeper wet avalanches at these interfaces. While wet slab avalanches are unlikely and very hard to forecast, they're important to keep in mind. These dangerously large avalanches could become a concern in future days.
