Lo esencial

Blowing and drifting snow have created dangerous avalanche conditions and the avalanche danger is CONSIDERABLE today. Human triggered avalanches are likely on steep, wind drifted slopes, and natural avalanches are possible off the steep, higher peaks. Above treeline, shallow wind slabs may be found on all aspects, but deeper drifts will have formed on slopes facing NW-N-E. Avoid steep slopes with recent deposits of wind drifted snow, and stay out from under high, steep faces that have a northerly aspect.

    Human triggered avalanches involving wind drifted snow are likely today, and we may also see some natural activity off the higher, steep faces. Sustained strong southerly winds have been blowing and drifting snow for the past 24 hours, and you may find shallow wind slabs on the lee sides of terrain features on all sides of the compass at upper elevations. Deeper drifts will be found on slopes facing NW-NE-E. Stay out from under high, steep faces with these aspects, and avoid steep slopes with recent deposits of wind drifted snow.

    Drifting snow has added additional stress to buried, persistent weak layers in the snowpack. Our primary layer of concern is the early December snow that has turned to weak, sugary facets. Today there remains a very real possibility for triggering a deep and dangerous avalanche on this weak layer. The danger is greatest on steep, upper elevation slopes facing NW-N-E, but in some areas the problem wraps around to W and SE facing slopes.

    Travis Nauman and Reed Kennard noted strengthening persistent weak layers in this observation but we aren't out of the woods yet.

Special Announcement

We will be offering a Backcountry 101 avalanche course on Feb 8, 9. It's a great way to up your avalanche knowledge with both classroom, and hands on field instruction.

Snow and Weather

About 4" of dense snow has fallen overnight but the real story is the wind. Blowing out of the south for the last 24 hours, winds have been averaging a steady 25-30 mph with gusts to 50. The trend will increase today with wind speeds of 30-40 mph, and gusts as high as 60 out of the SW. Snow should continue through the morning with another 2"-4" possible. High temps at 10,000' will be right around freezing, or slightly above what they are now. Needless to say, dangerous avalanche conditions will exist today, both from wind drifted snow, and from new stress being added to buried, persistent weak layers. If you are out and about, lay low and out of the wind as much as possible. Stick to low angle, wind sheltered terrain, and stay out from under steep slopes and high faces.

Travis Nauman and Reed Kennard were out yesterday and sent in this observation.
