Avalanche Problems

Wind Slabs

Winds gusting extreme through the Icefields from variable directions alpine - below treeline. Snow transport occurring creating various thickness windslabs over weak surface hoar layer. Several windpressed gullies avalanched naturally up to size 2.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible - Likely

Expected Size: 2 - 3

Persistent Slabs

Open slopes on Northeast to South aspects have persistent slabs that are sitting on the Valentine's Day surface hoar 20-60cm down. 35cm of snow may arrive Saturday-Monday potentially overloading slopes increasing natural activity.

Aspects: North, North East, East, South East, South.

Elevations: All elevations.
