New snow and wind loading have formed touchy storm slabs, especially on north through east facing slopes.
Stick to non-avalanche terrain or small features with limited consequence.
New snow and strong wind has formed touchy storm slabs. The snow arrives with significant wind, expect deposits to be deeper on north through east aspects.
On Tuesday, several natural (size 1-2) and human-triggered (up to size 2) slab avalanches were reported.
A fatal, human-triggered (size 3.5) happened on Tuesday in the adjacent forecast region near Anniversary glacier. This occurred on a wind loaded northeast slope in the alpine.
On Monday, the region saw a widespread natural avalanche cycle up to (size 3.5), this activity occurred during the storm.
Strong winds and new snow on Thursday will likely form fresh and reactive storm slabs at upper elevations. This adds to the 60 cm of storm snow that fell earlier this week, which sits on a variety of old snow surfaces, including stiff wind slab, facets, and crust.
The early February crust/facet layer is down approximately 8 to 100 cm.
Another widespread crust and facet layer from late January is buried 120 to 160 cm deep.
The mid and lower snowpack is well settled and strong.
