Isolated collapsing yesterday indicates that the recent snow load has begun to stress persistent weak layers buried deep in the snowpack. The snowpack structure is poor with a dense hard slab 2-3 feet thick on top of multiple layers of weak, sugary, faceted snow. Stability tests remain reactive but stubborn. Nevertheless, any avalanche triggered would be deep, dangerous, and possibly un-survivable. The danger is greatest on steep slopes near and above treeline where strong, southwest winds have deposited thick slabs on top of these weak layers and this type of terrain should be avoided. Northerly aspects below treeline also remain suspect with equally poor structure. The main difference is a lack of recent wind loading. In these areas, deep, human triggered avalanches remain possible.

Increasing northeast winds today will deposit snow in unusual places, particulary on south and westerly aspects. Be on the lookout for fresh slabs of wind drifted snow to form on the leeward sides of ridge crests and terrain features in exposed terrain. Wind slabs are often recognizable by their smooth, rounded appearance and cracking is a sign of instability.

Deep drifts that formed during the storm on northerly aspects will be less sensitive today but the primary concern there is the additioanl stress they have placed on buried persistent, weak layers. Steep, wind drifted slopes on the north side of the compass should be avoided.
