For nearly all areas, avalanche danger is LOW for all elevations and aspects. Very isolated pockets of MODERATE danger exist near and below treeline on N-NE aspects on slopes 35 degrees and steeper where a persistent weak layer exists near the base of the snowpack. Additional pockets of MODERATE danger may form later today if rain falls on the remaining areas of cold unconsolidated snow on N-NE aspects.

North of Hwy 88, avalanche danger near and above treeline is LOW with pockets of MODERATE danger lingering on recently wind loaded NW-N-NE-E aspects 35 degrees and steeper. Below treeline and all areas south of Hwy 88, avalanche danger is LOW. Please keep in mind that LOW danger means human trigger avalanches are unlikely, which is different than impossible, especially in highly complex or extreme terrain.

A continual increase in avalanche danger is expected to occur now through midnight tonight. This morning, avalanche danger both above and below treeline will rise to MODERATE danger in open areas 35 degrees and steeper. This afternoon, avalanche danger is expected to further increase to CONSIDERABLE danger near and above treeline on NW-N-NE-E-SE aspects 35 degrees and steeper. Late this afternoon and evening, areas of locally higher avalanche danger may exist if the upper end of forecast snowfall amounts are met or exceeded.

The avalanche danger will remain at EXTREME on NW-N-NE-E-SE aspects and HIGH on S-SW-W aspects steeper than 30 degrees at all elevations due to a combination of heavy snow and rain, high winds, and a very widespread weak layer of buried surface hoar. Widespread large natural and human-triggered avalanches are certain to continue today. Travel in or near avalanche terrain including low elevation road cuts and other steep hillsides is not recommended.

The avalanche danger is HIGH on NW-N-NE-E-SE aspects and CONSIDERABLE on S-SW-W aspects steeper than 30 degrees at all elevations due to a combination of heavy snow and rain, high winds, and uncertainty surrounding the weak layer of buried surface hoar. Widespread, large natural and human-triggered avalanches are likely to continue today. Travel in or near avalanche terrain including low elevation road cuts and other steep hillsides is not recommended.
