The storm has left unstable slabs of wind drifted snow and softer slabs of storm snow on steep slopes in both exposed and sheltered terrain. Recreating on slopes where these problems exist could trigger avalanches. Give the snowpack time to adjust to the new load before heading onto steep slopes. Plenty of nice snow exists on lower angle sheltered terrain. Expect CONSIDERABLE avalanche danger near and above treeline with MODERATE danger below treeline.

As the storm intensifies, heavy snow and gale-force winds will create very dangerous avalanche conditions in the backcountry today. Large unstable slabs of wind drifted snow and softer slabs of storm snow will exist on steep slopes in both exposed and sheltered terrain. During the day, the avalanche danger will increase to HIGH near and above treeline and CONSIDERABLE below treeline.

Travel in or below avalanche terrain is not recommended today.

Cold windy weather and limited new snow this afternoon should keep avalanche activity unlikely today. As more snow and wind impact the region tonight and tomorrow, the avalanche danger will increase dramatically. Today, icy slopes, breakable crusts, and generally challenging snow conditions will present other hazards for people like long sliding uncontrollable falls. Travel cautiously in the backcountry.

Recent snow and wind have built fresh slabs of wind drifted snow and large fragile cornices on and above slopes in near and above treeline terrain. Human triggered wind slab avalanches will be possible today. Slab avalanches breaking on a weak layer of buried surface hoar have become unlikely, but they may not be impossible on some isolated terrain feature. MODERATE avalanche danger exists at all elevations.

Slab avalanches 1 to 3 ft deep that break on a weak layer of buried surface hoar remain possible at all elevations today. New snow and wind may also form fresh slabs of wind drifted snow in some areas. These wind slabs could step down to break on the persistent weak layer. Choosing conservative terrain can help avoid getting caught by a persistent slab problem that is unusual for this area. MODERATE avalanche danger will continue.

People triggered slab avalanches 1 to 3 ft deep that broke on a weak layer of buried surface hoar yesterday. This persistent slab problem exists at all elevations. Unstable slabs of wind drifted snow may also break on this weak layer. People can still trigger persistent slab and wind slab avalanches today and they can still trigger them remotely from lower angle terrain. Choosing conservative terrain can help avoid getting caught by this unusual problem. MODERATE avalanche danger will continue.

Fresh slabs of wind drifted snow and fragile cornices should start to form in near and above treeline terrain today due to strong winds transporting old snow and new snow accumulation. In addition to these new wind slabs, an unlikely but not impossible deep slab problem still may exist on some isolated near and below treeline slopes. MODERATE avalanche danger exists at all elevations.

Pesky ENE winds have left small fresh slabs of wind drifted snow near upper elevation ridgelines. Daytime warming and sunshine may also allow some loose wet avalanche problems to form on lower elevation sunny slopes. On top of these two problems, an unlikely but not impossible deep slab problem still may exist on some isolated near and below treeline slopes. MODERATE avalanche danger continues.

Feet of new snow and shifting winds created dangerous avalanche conditions in the backcountry at all elevations. Human-triggered avalanches involving large slabs of drifted snow in wind-exposed areas and slabs of new snow in sheltered areas are likely today. In some places, deep slab avalanches involving all 5+ ft of the new snow failing on weak old snow are possible. Avalanche danger is CONSIDERABLE at all elevations. Be conservative and cautious in your terrain selection.
