Avalanche Summary
On Saturday, small (size 1-1.5) storm slabs and wind slabs were reactive to skier traffic. Cornices were reactive to explosives and triggered large (size 2) slab avalanches as they fell on the slopes below. Small storm slabs were triggered by skiers on Friday, within the recent storm snow up to 40 cm thick. The likelihood of triggering loose wet avalanches will increase if the sun shines, especially in areas with fresh snow.
Snowpack Summary
Around 20 to 30 cm of recent snow has been blown around by strong to extreme southerly wind. This snow overlies dry, cold snow on high-elevation northerly aspects and a melt-freeze crust elsewhere. Snow is melting rapidly at lower elevations.
