Weather Forecast
Wednesday will be cloudy with sunny periods with no precipitation expected. Alpine temperature will reach a high of 0 C, with freezing levels climbing to 2100m. Ridge-top winds will be out of the west at 20 km/h gusting to 50 km/h. Thursday will be slightly cooler, and then a weak system approaches the region on Friday.
Avalanche Summary
Several loose wet up to size 1.5 were observed today principally on solar aspects. Avalanche control on EEOR produced 5 avalanches up to size 2.0 that ran full path.
Snowpack Summary
Snowpack is settling with warm temperatures. Surface snow went moist on all aspects at all elevations except for extremely sheltered and shaded North aspects. Crusts are likely to form by morning. Cornices are sagging, and if they fail they could produce sizable avalanches on the slopes below. Recently formed storm slabs and wind slabs are gaining strength and becoming less of a concern. The chief problem in the snowpack remains the Jan 6th interface of surface hoar/sun crust/facets. This layer is down 35 to 80cm and continues to produce shears in snowpack stability tests. If this layer is triggered, large avalanches are possible.
