Weather Forecast
A mix of sun and cloud and generally dry for Tuesday before a weak storm pushes through overnight Tuesday with 10-15 cm expected by Wednesday afternoon, accompanied by moderate to strong southwesterly ridgetop winds. Another dry day is expected for Thursday. Daytime high freezing levels are expected to hover around 1100 m for the forecast period.
Avalanche Summary
No recent avalanche observations reported. If you have been out in the mountains, please submit your observations to the Mountain Information Network (MIN).
Snowpack Summary
Another 25-30 cm brings total snowpack depths to around 150 cm at treeline, and 2 m or more at higher elevations. This new snow continues to build weak storm slabs with particularly deep and touchy wind slabs on leeward slopes in exposed areas. Recent reports suggest that trail breaking and downhill travel was difficult due to the deep and heavy storm snow.
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.
