Avalanche Forecast
Issued: Feb 4th, 2021 3:00PM
The alpine rating is Wind Slabs and Storm Slabs.
, the treeline rating is , and the below treeline rating is Known problems includeLots of new snow, now lots of wind. Caution with overhead hazards as the wind transports snow in the alpine. When traveling in the terrain it is important to watch the snow, if it change from light powder to heaver more dense snow the slab will be more reactive. Good tree skiing
Summary
Confidence
Moderate -
Weather Forecast
A trace amounts of snow over the past 24hr. We are going to start to seeing a cooling trend over the next couple of days. Along with the change in weather there is fairly strong winds forecasted. 60-80km changing to a more north flow.
Avalanche Summary
Evidence of the older cycle, no new avalanches observed, but no observation of the alpine as well very limited field observations.
Snowpack Summary
Lots of new snow out there. We have anywhere from 35-60cm of settling storm snow from the last couple of days. Currently, this snow is low density in the valley bottoms, but stiffens up as elevation is gained. Alpine and treeline winds have begun to create fresh windslabs on eastern aspects. There are also buried windslabs within the storm snow. The Jan 29 (hard windslab/storm snow) interface is slower to bond than expected. Less avalanche activity seen today but no real alpine observations. Winds slab are forming and suspect they will be touchy in the right spot. Deep layers are still hanging in there and so far not failing wit the new load.
Some steep solar aspects may have a sun crust.
Terrain and Travel
- Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
- Be careful as you transition into wind affected terrain.
- Continue to make conservative terrain choices while the storm snow settles and stabilizes.
- Shooting cracks, whumphs and recent avalanches are strong indicators of an unstable snowpack.
Problems
Wind Slabs
Lots of snow available for transport right now. Expect windslabs to build quickly in windy areas. We also have a buried windslab problem that may not be apparent unless you dig to find them.

Storm Slabs
As all the new snow settles it may become more reactive as it becomes more of a slab.
