Highlights

A CONSIDERABLE avalanche danger exists on steep, mid and upper elevation, wind drifted slopes that face NW through E and human triggered avalanches are likely in these areas.

The avalanche danger is MODERATE on low elevation northerly aspects and on mid and upper elevation slopes facing W and SE where you can detect recent deposits of wind drifted snow.

Most S-SW facing terrain has generally LOW danger.

It's also still very low tide out there. Beware of rocks, stumps, and deadfall lurking beneath the surface.

    On slopes facing NW through E, fresh deposits of wind drifted snow have formed over top of a dense slab, 2'-3' thick, that exists on a persistent weak layer of loose, sugary facets. Over the past two weeks, these slabs have grown increasingly stubborn to release but to be sure, any avalanche triggered on this weak, faceted layer would be deep and dangerous. With more wind drifted snow continuing to add stress to this persistent weak layer, steep slopes facing NW through E are best avoided.

    Blowing and drifting snow has formed new wind slabs on leeward slopes that face primarily NW through E, with some cross-loading possible on W and SE facing slopes. On northerly aspects, wind drifted snow has added stress to older slabs on top of a buried persistent weak layer and dangerous, human triggered avalanches 2'-3' deep are possible. Avoid steep, wind drifted slopes, especially those that face the north side of the compass.

Special Announcement

Road Conditions: Expect to find a few inches of new snow with areas of drifting.

Recent Activity

Dave Garcia ran across this old but previously unreported avalanche in Coyote Chute. Like all the other slides this season, it was about 2.5" deep and failed on the October facets. Here is the current avalanche list.

NWS Weather Forecast

The story today is the wind. A fast moving short wave trough will sweep through the area today bringing strong southwesterly winds and perhaps a few inches of snow. Pre Laurel Peak wind station is still rimed up but stations throughout the region are reporting strong southerly winds averaging 25-35 mph with regular gusts into the 50's and 60's, with Gold Hill in Telluride registering gusts to 80 mph. High temps today will be in the low 20's. A deep trough will remain entrenched over the west with successive waves moving through between now and Thursday. None of the action to date has brought us much in the way of significant snowfall and the next two waves seem to be repeat performances, but a system later in the week holds promise.

Snowpack

5" of dense new snow accompanied by moderate to strong SW winds plastered the mountains yesterday with snow even sticking to southerly aspects. Dave Garcia was up and reported that the new snow had a "styrofoam" feel that was "slightly upside down and grabby (but also) supportable, surfy, and fun." He also reported fresh wind drifts on northerly aspects, as well as observing this old, but previously unreported avalanche in Coyote Chute. Read his full observation here. On terrain facing NW through E an older, dense slab, 2'-3' thick exists over weak, October facets. The recent snow does not appear to have affected this buried persistent weak layer, but it is possible that a triggered wind slab could result in a deeper and much more dangerous avalanche. With continued strong winds and chance of snow in the forecast, continue to avoid steep, northerly aspects, especially where you can detect recent deposits of wind drifted snow.

Overall snow cover remains quite thin and rocks, stumps, and deadfall continue to pose hazards.
