Likelihood of triggering avalanches is still possible, even large avalanches in isolated areas.
Weather Forecast
Today cloudy with sunny periods, no precipitation, an alpine high of -6 deg, freezing level to 1200m and winds SE 20km. No significant precipitation for the for seeable future, with temps near seasonal averages.
Snowpack Summary
30-50cm of recent storm snow is settling and slowly bonding to the mid january interface. 3 layers in the storm snow producing mod-hard results on stability tests with resistant to broken characteristics. The Dec 18th interface is buried approx 1m and unreactive to stability tests, while the Nov 13 crust lies 1.5-2.5m beneath the surface.
Avalanche Summary
Four new avalanches observed yesterday in the highway corridor on N-NE asp to size 2, and no new avalanches reported from the back country. Large destructive avalanches ran full path on Wednesday and Thursday in the Highway corridor up to size 3.5. Reports from the back country observed natural slab avalanches to size 2.5 occurred during storm.
Problems
Storm Slabs
Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
