Avalanche Summary
There was one report of a size 1.5 slab avalanche from a steep south aspect in the alpine on Thursday that appeared to involve the recent storm snow. There were also a few size 1 loose snow avalanches were reported running out of steep terrain.
Snowpack Summary
Up to 15 cm of recent snowfall has been redistributed into dense or hard wind slabs at higher elevations from variable winds. Moist snow or a hard sun crust is likley on steep solar aspects depending on whether or not the sun is shining. The new storm snow overlies old wind slabs in exposed areas, settled storm snow or spotty surface hoar in more sheltered terrain, and a crust on previously sun-exposed slopes. A variable interface (surface hoar/facets/sun crust) was buried on Jan 23 and is down about 20-40cm. In most locations it now appears to be well bonded. The lower snowpack is generally well-settled. Cornices in the region are reported to be well developed and loom over heavily used slopes. These cornices deserve our respect, especially with clear skies and warming forecast for the weekend.
