Past winds have been strong and from the southwest, it may be possible to find wind slabs lingering in lee terrain.
It's still warm at higher elevations, so be cautious of overhead hazards and large terrain.
It is uncertain how the continued warmth will affect the snowpack so watch for signs of instability
Past winds have been strong and from the southwest, it may be possible to find wind slabs lingering in lee terrain.
A buried layer of surface hoar on a crust is particularly concerning in the north of this region.
This layer may become more reactive as the warm air lingers.
Steep south aspect terrain will begin to destabilize when temperatures rise and the sun is out.
Consider avoiding these features during daytime warming.

No new avalanches reported but observations are limited. Consider posting to the MIN if you are out in the mountains!
January 16
A large (size 2) natural cornice triggered avalanche was reported on a northwest aspect.
January 14
A natural avalanche cycle was reported, with small (size 1) wet avalanches at lower elevations and large (up to size 2.5) wind or persistent slab avalanches in the treeline and alpine.
80 to 150 cm of snow fell early last week accompanied by strong southerly winds at upper elevations and has settled from warm temperatures at all elevations.
In sheltered ares at lower elevations this snow is possibly resting on surface hoar.
On steep south aspect slopes a surface crust is present in the alpine.
At treeline and below, rain and warm temperatures may have affected the surface snow. As temperatures cool this warm and wet snow has formed a stout melt freeze crust.
The mid and lower snowpack is well settled with no current layers of concern. Treeline snow depths throughout the region range from 150 cm to 250 cm.
