In sintesi

Although the storm has eased off, storm slabs are still likely to be encountered and could be reactive to human triggering, especially in wind loaded areas and as temperatures rise.

Avalanche Summary

A few natural and human triggered avalanches to size 1.5 were reported in the region on Tuesday.No new avalanches were reported on Monday.A few small (size 1) wind slab avalanches were triggered naturally in the region on Sunday.

Snowpack Summary

A few stormy days brought total recent snowfall amounts to approximately 40-70 cm.  This snow fell onto a sun crust on south facing slopes, a melt freeze crust below approximately 1700 m on all aspects, and surface hoar (feathery crystals) in areas sheltered from the wind at all elevations.  The recent snow may not bond well to these layers.In some areas, another weak layer of surface hoar is buried about 60 to 100 cm in sheltered areas around treeline elevations.
