Avalanche Forecast
Regions: Little Yoho.
We are still worried about thinner areas in the alpine. Watch for lee slabs and areas of rotten snow under slab.
Weather Forecast
The upper level flow puts our region back in the storm track, and a series of minor storms will cross the region over the next few days. Most of the punch will be to the west, but expect 5-10 cm on Thursday with strong alpine winds developing through the day. Temps at treeline will remain steady at -4 to -10 all week.
Snowpack Summary
20-30 cm of recent storm snow overlies suncrust in places. Generally, the middle of the snowpack is well consolidated in the deeper areas. Expect to find windslabs forming in lee areas above treeline.
Avalanche Summary
No new avalanches observed other than sluffing in really steep terrain.
Confidence
Avalanche Problems
Persistent Slabs
We believe the persistent weak layers from January and February have a low likelihood of triggering, but are not yet prepared to say they are gone. The snowpack is strong, but check for yourself and look for surface hoar in the upper meter.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Unlikely
Expected Size: 2 - 3
Wind Slabs
Strong winds on Thursday may create windslabs 30-40 cm deep in predictable areas leeward of ridges. Pay close attention to how the snow surface feels, and look for clues like cracking or ski test on small rolls.
Aspects: North, North East, East.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 2
