Regions: Waterton Lakes.
Wind slabs that developed from the storm snow we received earlier this week are the main concern right now. Warm temperatures will mean sun crusts on south aspects. Unless we get a lot more than the 5cm predicted avalanche danger will not change.
Avalanche Problems
Wind Slabs
Steady winds have been building wind slabs on NE aspects. Under these wind slabs could be the surface hoar layer from Feb 9 or thin temperature crust on south aspects. Warm temperatures will help settle these but don't underestimate their potential.
Aspects: North, North East, East, South East.
Elevations: Alpine, Treeline.
Likelihood: Unlikely - Possible
Expected Size: 1 - 2
