Avalanche Summary
Observations were limited on Wednesday; however, explosives control produced slab avalanches to size 2 which formed in response to strong winds and rapid loading. On Thursday a size 2 slab was ski cut on a northeast aspect (unknown elevation). The bed surface was the early April temperature crust.
Snowpack Summary
Moderate amounts of snow fell on Wednesday. In the south of the region, heavy accumulations (~40cm) were observed. At lower elevations rain continued to saturate the snowpack. The storm was accompanied by moderate to strong south/southwest winds which left variable snow distribution in exposed terrain with dense wind slabs forming in lee and cross-loaded features. Up to 85cm below the surface you will likely find a melt-freeze crust from last week's sunny weather. At the same interface, you may find spotty surface hoar on high north facing terrain. Large natural activity and remote triggers from earlier in the week suggest the surface hoar may continue to be reactive, especially with the weight of the new snow. Cornices are very large and could pop off with continued mild temperatures.
