Avalanche Forecast
Regions: Little Yoho.
Continued load on the weak base will have the potential to wake up the weak base on slopes that have not yet avalanched. We are in a period of slowly rising avalanche danger. JBW
Weather Forecast
A series of pacific storms in a westerly flow will bring precipitation to the west sides of the divide and warm westerly winds to the east. The strongest in the series looks to be Friday night into Saturday and may be enough to bump the avalanche danger rating higher.
Snowpack Summary
Some light wind transport and a trace of new snow today with the first in a series of storms in a strong westerly flow. Last weeks storm snow is settling, but the weak base of depth hoar and/or crust is still the major concern.
Avalanche Summary
The natural avalanche activity triggered by last weeks storm has subsided and no new avalanches have been observed in the last 36 hrs. The potential for triggering still remains likely.
Confidence
Intensity of incoming weather systems is uncertain on Saturday
Avalanche Problems
Deep Persistent Slabs
The weak base is the real danger. Moderately angled slopes with thicker snowpack are the best choices for not triggering this layer.
- Watch for whumpfing, hollow sounds, and shooting cracks.
- Be aware of the potential for full depth avalanches due to deeply buried weak layers.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 2 - 3
Wind Slabs
Fresh storm slabs can be triggered and will have the potential to step down to the weak base.
- Avoid freshly wind loaded features.
- Be careful with wind loaded pockets while approaching and climbing ice routes.
Aspects: North, North East, East, South East, South.
Elevations: Alpine, Treeline.
Likelihood: Likely
Expected Size: 1 - 2
