Regions: Jasper.
The recent storm snow is bonding well yet explosive control work released a few large avalanches to ground. Evaluate terrain carefully especially large features.

Avalanche Problems
Wind Slabs
Recent 45cm storm snow has melded into the windslab. Trigger spots are shallow snowpack locations which could initiate a deeper release. Windslabs present lee features. Evaluate local wind effect as directions have been variable.
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Possible
Expected Size: 1 - 3
Deep Persistent Slabs
Large explosives released a few size 3's to ground today. Midpack strength is generally bridging this layer but the potential still exists if triggered. Consequences would be severe. Natural avalanches unlikely but human triggered possible.
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Unlikely - Possible
Expected Size: 2 - 4
