At mid and lower elevations the danger remains CONSIDERABLE on steep slopes that face NW-N-SE. The danger is MODERATE on mid and low elevation terrain on slopes that face S-W.

current conditions

Heavy snowfall and strong winds have created areas of deep drifted snow, alternating with scoured zones and thick wind crusts. All told, the mountains have received 40" of snow above 10,000' since last Thursday night. Winds on Monday averaged 30-40 mph for several hours with regular gusts over 70. Use the links below for current wind, snow totals, and temperature.

recent activity

On Saturday, a party remotely triggered this avalanche on a north facing slope at 10,400'. The avalanche likely failed on buried near surface facets under the load of new storm snow, eventually stepping down to deeper faceted layers around rocks.

Strong winds and heavy snowfall, have caused deep wind slabs to form on the lee sides of ridge crests and terrain features. The danger will be greatest on slopes facing the north half of the compass, but with so much snow blowing around, wind slabs will have formed on all aspects wherever terrain features are able to capture drifting snow.

description

Heavy snowfall and wind loading have increased the stress on buried weak layers within the snowpack. Avalanches initiated within the new snow now have the potential to step down into these buried weak layers. In some cases this could mean stepping down to buried near surface facets that formed prior to the beginning of this last storm cycle. In other cases, it could mean stepping down to weak, faceted snow near the ground.
