This morning the avalanche danger is LOW for all elevations and aspects. MODERATE avalanche danger may form on the E-SE-S-SW-W aspects in both above and below treeline terrain on slopes steeper than 35 degrees due to daytime warming. Some pockets of MODERATE danger could also form on the below treeline NW-N-NE aspects. Human triggered wet snow avalanches will become possible.

MODERATE avalanche danger exists today on slopes steeper than 35 degrees in both above and below treeline on NW-N-NE-E-SE aspects with pockets of MODERATE danger on the S aspects. Lingering wind slabs in isolated areas and heavy snow loads sitting on top of weak persistent deep slabs will allow large destructive human triggered avalanches to remain possible.

The avalanche danger is HIGH at all elevations on the NW-N-NE-E-SE aspects on slopes steeper than 33 degrees due to wind slabs and heavy snow loads accumulating on an already weak snowpack. Large, destructive human triggered and natural avalanches will be widespread today. Very Dangerous avalanche conditions exist, and travel in or below avalanche terrain is not recommenced.

Both above and below treeline, avalanche danger will rise to CONSIDERABLE today on NW-N-NE aspects on slopes 35 degrees and steeper due to wind slabs and persistent slabs. For other areas, avalanche danger is MODERATE on slopes 35 degrees and steeper. Avalanche danger is expected to further increase to HIGH danger tonight as continued snowfall occurs.

Near and above treeline pockets of CONSIDERABLE avalanche danger remain on the NW-N-NE-E aspects on slopes steeper than 35 degrees due to fragile wind slabs resting on buried weak layers. Below treeline, the avalanche danger is MODERATE on wind loaded NW-N-NE-E aspects steeper than 35 degrees. Human triggered avalanches will be possible in many areas today and likely in some of the most heavily wind loaded areas.

UPDATED AT 9:00am

Near and above treeline the avalanche danger is CONSIDERABLE on the NW-N-NE-E aspects on slopes 35 degrees and steeper due to continued wind and new snow. Below treeline, pockets of CONSIDERABLE avalanche danger exist on wind loaded NW-N-NE-E aspects steeper than 35 degrees. Human triggered avalanches will be likely today and natural avalanches will be possible.

Near and above treeline the avalanche danger will increase to MODERATE on NW-N-NE-E aspects steeper than 35 degrees due to new snow and wind. Pockets of MODERATE danger may form on those aspects in wind loaded below treeline terrain as well. Human triggered avalanches will be possible today. Use caution and evaluate snow covered slopes carefully when traveling in the backcountry.
