Avalanche Forecast

Fair

Very light accumulations are expected till tomorrow am with SW-NW moderate winds. The Western part of the region will see most of those precipitations. Sunny periods and broken clouds are still expected for Friday, seasonal temperatures throughout the whole period (-8 C) and light winds from the North West.  The upper trough arriving on Saturday should bring light to moderate precipitations on the regions, again, with Westerly upslope seeing most of it. Winds should pick up to reach moderate to strong speeds from the South West. Another system is following for Sunday, its timing and intensity remain to see.

A few small soft slabs were skier triggered on East and South aspects. An older (approximately from Dec. 10th) natural slab avalanche size 2.5 was also observed on an East facing windloaded convex slope. The crown was an average of 60 cm deep. There was also multiple releases from explosives that ran in the new snow from North West to South East facing slopes.

Windslabs are still a concern in specific areas (Easterly aspects) in the alpine and at treeline with the forecasted light precipitations, moderate winds and the older snow available for transport.  The new snow is also burying some older slightly deeper windslabs in sheltered areas. Overall, the upper snowpack is reported to be settling well.  The November 28 surface hoar down 100-140 cm (between 1500 and 2000 m) is producing moderate to no results. The early November crust down 150-200 cm is also still a concern producing sudden collapses to no results. Professionals are still cautious in relation to these lingering deep problems, but the slow and improving trend hopefully allows us to step it down or even maybe take it out of the primary concerns in the near future.
