It looks as though we have one more day to go before the next storm arrives. As always, if the new snow comes early expect a quick increase in avalanche hazard.
Summary
Confidence
Weather Forecast
A warm front is on the way and its scheduled to arrive tomorrow morning. Temps will rise to -4 by mid afternoon, snow will start in the morning and winds will pick up as the day goes on. Most of the snow will come on Saturday. Tomorrow will only see 5-10cm and moderate winds out of the SW.
Avalanche Summary
nothing new today
Snowpack Summary
Widespread wind affect at all elevations. The upper snow pack is a series of windslabs stacked on top of each other. They feel as though they are weakening (ie softening) with the recent flatline weather pattern. In a pit today, there was 135cm of snow, with the lower 30cm consisting of facets & depth hoar. Tests were inconsistent with the deep persistent layer.
Terrain and Travel
- If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
- Carefully evaluate steep lines for wind slabs.
- Avoid lee and cross-loaded slopes at and above treeline.
Problems
Wind Slabs
The windslabs are stacked up on each other and may have weak layers hidden in between them.
Aspects: North, North East, East, South East, South.
Elevations: Alpine, Treeline.

Expected Size
Deep Persistent Slabs
It is worth to dig a pit to ground to see the severity of this basal layer. If it hasnt yet slid, treat it with a high degree of suspicion and respect. If it goes, it will be big.
Aspects: All aspects.
Elevations: Alpine, Treeline.
