Avalanche Summary
We suspect skier triggerable wind and storm slabs will be found on Saturday.
On Thursday ski cutting produced a few size one loose wet avalanches in steep terrain.
Snowpack Summary
New snow accompanied by westerly winds will likely build new storm and wind slabs throughout the day on Saturday.
The mid February crust is down 15cm and exists on all aspects and elevations.
The late-January melt-freeze crust is now down around 40 cm and is reported to be knife hard and up to 30 cm thick. This crust extends to at least the top of treeline and is generally well bonded to the adjacent snow.Â
The middle and lower snowpack are considered well settled and strong.
Terrain and Travel
- Watch for fresh storm slabs building throughout the day.
- Closely monitor how the new snow is bonding to the crust.
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
Problems
Storm Slabs
New wind and storm slabs will form throughout the day. It is possible that these slabs will be touchy due to the crust they will form over.
Aspects: All aspects.
