Avalanche Forecast
Regions: Glacier.
Weather Forecast
Today will remain unsettled with convective flurries and potentially some sunny breaks. Moderate, but gusting to strong, westerly winds will be transporting the new snow building cornices and loading lee slopes. Thursday should be dry with a mix of sun and cloud. Alpine temps will reach -4'C. On Friday expect flurries and SW winds.
Snowpack Summary
Temps cooled off overnight, and at 1300m 3cm of snow overlies a 3cm thick crust. At 1900m ~20cm of dry snow overlies 30cm of heavy wet snow at treeline. This adds to the load sitting on a series of crust layers. Snowpack tests indicate that these layers may be triggerable by light loads, and if triggered are capable of propagating widely.
Avalanche Summary
Numerous size 2-3, loose wet avalanches were observed along the highway corridor. Avalanche activity tapered off in the afternoon as temps cooled, precipitation rates decreased and winds died down.
Confidence
Timing or intensity of solar radiation is uncertain
