- Watch for signs of instability such as whumpfing, shooting cracks or recent natural avalanches.
Avalanche Summary
No new avalanches reported.
Avalanche activity is expected to increase with the wind-driven snow on Sunday, especially on north through east aspects at higher elevations.
Snowpack Summary
A light dusting of new snow covers the melt-freeze crust that formed on all aspects and elevations. On north aspects this crust is thin with dry, sugary snow crystals (facets) below.
Beneath the surface, the upper snowpack is well settled and overlies a thin layer of facets on the late-November rain crust. Snowpack tests found hard, sudden compression test results on the facets just above the crust, which is now down approximately 50 cm at tree line elevations.
The lower snowpack is well settled and consists of several crusts that formed in the early season.
Weather Forecast
After a long drought we'll see some new snow, blown in by southwest winds.
SUNDAY: Snow. Accumulation 10-15 cm. Ridge wind moderate from the southwest. Freezing level 1000 m.
MONDAY: Cloudy, flurries. Accumulation up to 5 cm. Ridge wind light from the west. Freezing level 700 m.
TUESDAY: Snow. Accumulation up to 10-20 cm. Ridge wind moderate from the south west. Freezing level 800 m.
