The windslabs are stacked up on each other and may have weak layers hidden in between them.

Lo esencial
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.

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.
Confidence
Moderate - Forecast snowfall amounts are uncertain.
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.

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.
