Avalanche Problems
Wind Slabs
Extreme winds at the Icefields is redistributing the storm snow. Trigger spots are shallow locations. Initiating could release a deep slab. Evaluate local wind effect as directions have been variable. Storm arriving tonight will add further load.
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Unlikely - Possible
Expected Size: 1 - 3
Deep Persistent Slabs
Friday's explosives released size 3's to ground. Midpack strength is bridging this layer from human triggering but the potential exists. Consequences would be severe. Natural activity has tapered off but may increase with tonight's storm.
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Unlikely - Possible
Expected Size: 2 - 4
