A patrol to North end of Medicine lake noted several low elevation loose wet avalanches along Medicine slabs. The team's morning patrol on the Parkway only got to the Icefields center where the snow was too deep to proceed. Visibility was poor and it was a blizzard.

Avalanche Problems
Storm Slabs
Up to 40 cm in last 24 hrs with Mod SW winds. We should see widespread avalanche activity at all elevation with large avalanches running full path.
- It is a good time to stay within the boundaries of a ski resort.
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Very Likely
Expected Size: 1.5 - 4
Deep Persistent Slabs
It is very likely that this new and heavy snow load will overload this weakness and we will see avalanches running to ground on this layer. No one should be entering avalanche terrain at this time!
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Likely
Expected Size: 1.5 - 4
