Wind slabs continue to linger in steep alpine terrain. Pay attention as new snow on Monday begins to accumulate over a wide-spread crust.
A couple of skier-triggered avalanches surprised a ski touring group on Saturday. Both avalanches were reported as size 2 and occurred on a northeast, alpine slopes just below a rocky ridge top.
If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).
On the surface is a recently formed melt-freeze crust, observed up to 2000 m, and may exist higher by Monday morning. Roughly 10 to 20 cm of dry snow beneath the crust is settling over various, wind-affected surfaces created during the recent extreme cold period.
The mid and lower snowpack consists of various crusts and layers of facets or surface hoar. Reports indicate these are not currently a concern.
Cloudy with trace snow amounts, southwest alpine winds 10 to 30 km/h, treeline temperatures -2 °C. Freezing levels around 1400 m.
Cloudy with 2 to 8 cm of snow, southwest alpine winds 10 to 30 km/h, treeline temperature -2 °C. Freezing levels around 1200 m.
Cloudy with 2 to 8 cm of snow, southwest alpine winds 20 to 40 km/h, treeline temperature -4 °C.
Cloudy with trace snow amounts, southwest alpine winds 20 to 40 km/h, treeline temperature -4 °C.

Terrain and Travel Advice
- Avoid freshly wind loaded features, especially near ridge crests, roll-overs and in steep terrain.
- A crust on the surface will help bind the snow together, but may make for tough travel conditions.
- Closely monitor how the new snow is bonding to the crust.
Wind slabs continue to persist in alpine terrain, especially near ridge crests and steep convexities (roll-overs).
