Kernpunkte

Conditions remain dangerous where snow that fell last week lies upon faceted old snow layers. Persistent weak layers continue to fail due to the weight of single person. This snowpack should not be trusted. Dangerous slab avalanches could be triggered remotely. Tracks on a slope should not be considered to be an indication of stability. Excellent terrain evaluation and route selection skills, a comprehensive understanding of the distribution of persistent weak layers and conservative terrain choices are essential for safe travel in avalanche terrain. Avalanches are unlikely below an elevation of 8,000 feet where last week's new snow lies directly upon bare ground.

    Buried crusts and persistent weak layers of faceted snow exist in terrain that held snow prior to November 24. This terrain generally includes all aspects above 9,000 feet and northerly slopes down to 8,000 feet. Skiers and riders who venture into these areas could trigger slab avalanches that are one to three feet deep. Understanding and identifying where the old weak snow is present is essential in avoiding this hazard.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Moisture will begin to move into the area during the afternoon hours. Expect light snow to develop at the higher elevations before a steady stream of moisture brings moderate to heavy snowfall to the region later in the evening and into Sunday morning. Temperatures will remain in the 20s at the higher elevations and rise into the 30s in the valleys. Winds from the southwest will increase to 15 to 20 miles per hour.Persistent weak layers at the mid and upper elevations remain sensitive to the weight of a single person. Humans who venture onto steep slopes could trigger large slab avalanches up to three feet deep. The general avalanche hazard is considerable at the mid and upper elevations. Safe travel there requires excellent terrain and route selection skills, a comprehensive understanding of the distribution of existing persistent weak layers and conservative terrain choices. The general avalanche hazard is low below an elevation of 8,000 feet.
