Strong to extreme SW winds and new snow will form windslabs in lees.
A few significant large avalanches ran on this layer last week.
Deep persistent slabs are best managed by:
Cornices are best managed by:
Tuesday: Cloudy with flurries, 10-15 cm accumulation. Moderate west winds. Alpine high -15. FL valley bottom.
Wednesday: Clearing through day. Moderate west winds. Alpine high -8. FL valley bottom.
Thursday: Partially cloudy with flurries. Strong extreme west winds. Alpine high -5. FL 1500m.
Freezing levels on monday rose to 2100m. A 15 cm rain crust exist up to 2000m. A 1 cm temp crust exists to 2400m on solar aspects. Alpine surfaces range from hard windslab in lees and to bare ground. Well settled midpack. Facets above Dec 4 crust down 150-200 cm. A 20-60 cm thick Nov crust complex completes snowpack to ground.
Evidence of previous cycle (Jan 8-12), with avalanches from size 2 - 4 can still be seen in most avalanche paths. No new avalanches reported or observed today. Limited field observations. Thanks to everyone posting on the Mountain Information Network, keep up the great work, we really do read them.
