~50cm of recent snow, moderate to strong SW winds and warm temps have formed storm slabs, which bury the Feb 15 surface hoar (2-8mm) and a crust on steep solar aspects. The slabs may be sensitive to human triggering.
Weather Forecast
Flurries are expected throughout the day on Sunday with accumulations up to 5cm. The freezing level will remain at valley bottom with an alpine high of -10. Ridge top winds will be 10-20km/hr from the North as the Arctic Polar Plunge moves into our region, gradually dropping temps into the -20's again for a few days. Clearing skies by Tuesday.
Snowpack Summary
The accumulating storm snow (~50cm) buried small surface hoar (Feb 15 SH 2-8mm) in sheltered areas below tree line, a crust on steep solar slopes and firm wind affected surfaces in the alpine. The Jan 29 surface hoar is down 70-120cm and is breaking down. Wind affected snow in the alpine and down into tree line.
Avalanche Summary
On Saturday, natural avalanche activity was observed up to size 3.0 and artillery controlled avalanche results up to size 3.5. Cheops North 4 was reported to be down into the creek, sz 2.5-3.0.
Numerous human triggered storm slab avalanches on Friday up to size 1.5.
