    Recent moderate to strong wind and heavy precipitation has formed storm slabs that increase in depth and reactivity with elevation. Expect deeper slabs and touchier conditions on the lee side of wind exposed terrain features.

Avalanche Summary

On Thursday expect reactive storm and wind slab avalanches in the alpine and tree line elevation bands where the recent precipitation has fallen as snow. Below tree line expect small loose snow avalanches where rain has soaked the snowpack.

Snowpack Summary

The last 48 hours has seen very heavy amounts of precipitation. The freezing level hovered around tree line during that time. Reports from the region have been few and far between, however it can be expected that 70-100cm of snow has fallen at upper elevations. The new snow would have been redistributed by moderate to strong southwest wind and is sitting on a well settled lower snowpack. Rain below tree line has soaked an already moist and/or wet lower snowpack.
