Avalanche Summary
Avalanche observations have been limited in the last few days; however, 2 explosives controlled size 2.5 slab avalanches were reported on Wednesday from the Duffey Lake area. They occurred on a north facing alpine slope and ran 1000-1400m.
Snowpack Summary
Up to 10cm of new snow has fallen at higher elevations. This overlies Wednesday's moderate to locally heavy amounts. At lower elevations rain continues to saturate the snowpack. The previous storm was accompanied by moderate to strong south/southwest winds which left variable snow distribution in exposed areas near ridgetop, with dense wind slabs forming in lee and cross-loaded features. Up to 75cm below the surface you will likely find a melt-freeze crust from last week's sunny weather. At the same interface, you may also find spotty surface hoar on some high, north facing slopes.Cornices are huge!
