The avalanche danger is LOW for most elevations and aspects. Pockets of MODERATE danger still exist on NW-N-NE aspects, 35 degrees and steeper between 7,400' and 8,700'. Avalanches may be more difficult to trigger today; however, if triggered, they could be large and have serious consequences.

Near and above treeline, avalanche danger is LOW with pockets of MODERATE danger on NW-N-NE-E-SE aspects, 35 degrees and steeper. Below treeline, avalanche danger is LOW with pockets of MODERATE danger on N-NE aspects, 37 degrees and steeper between 7,400' and 8,700'. Avalanches may be more difficult to trigger today, but are likely to be large in size with potential consequences severe.

Near and above treeline on slopes steeper than 35 degrees, the avalanche danger is MODERATE with pockets CONSIDERABLE on NW-N-NE-E aspects. Below treeline the avalanche danger on slopes steeper than 35 degrees remains CONSIDERABLE on NW-N-NE-E aspects, especially on slopes below 7800' in elevation. On the SE-S-SW-W aspects the avalanche danger is MODERATE at all elevations on slopes steeper than 35 degrees.

On slopes steeper than 35 degrees, the avalanche danger is CONSIDERABLE on NW-N-NE-E aspects at all elevations. Pockets of HIGH danger exist on the NW-N-NE aspects below 8700'.  On the SE-S-SW-W aspects the avalanche danger is MODERATE at all elevations. The avalanche danger will be higher on any slopes that receive rain today.

Avalanche danger is MODERATE both above and below treeline on N-NE aspects 35 degrees and steeper due to persistent deep slab instability. Elsewhere, avalanche danger is LOW. Possible consequences from human triggered avalanches remain high. Use good travel habits to minimize risk.

Near and above treeline the avalanche danger is CONSIDERABLE on NW-N-NE-E aspects steeper than 37 degrees. Pockets of CONSIDERABLE danger should also exist on slopes steeper than 37 degrees on the NW-N-NE-E aspects below treeline. Avalanche activity will be less likely on the windward SE-S-SW aspects.

Large natural and human-triggered avalanches are likely. Near and above treeline the avalanche danger is HIGH on NW-N-NE-E aspects steeper than 35 degrees. Pockets of HIGH danger should also exist on slopes steeper than 35 degrees on the NW-N-NE-E aspects below treeline. Avalanche activity will be less likely on the windward SE-S-SW aspects. Backcountry travel in or around avalanche terrain is not recommended.

Large natural and human-triggered avalanches are likely. Near and above treeline the avalanche danger will increase to HIGH on NW-N-NE-E aspects steeper than 35 degrees by this afternoon. Pockets of HIGH danger should also develop on slopes steeper than 35 degrees on cross loaded W aspects at all evelations and on the NW-N-NE-E aspects below treeline. Avalanche activity will be less likely on the windward SE-S-SW aspects. Backcountry travel in or around avalanche terrain is not recommended.
