Avalanche Forecast
Issued: Feb 16th, 2019 4:00PM
The alpine rating is Deep Persistent Slabs and Loose Dry.
, the treeline rating is , and the below treeline rating is Known problems includeModerate danger rating means human triggered avalanches are possible. Shallow rocky areas have the potential to catch someone off guard. Evaluate snow and terrain carefully.
Summary
Weather Forecast
Sunday forecasted to have sunny skies with scattered cloud. Alpine high -18 C. No new snow. Light north and easterly winds: 10 km/h. A detailed mountain weather forecast is available from Avalanche Canada.
Snowpack Summary
Cold temperatures have faceted the upper snowpack, leaving no slab over a weakness down 40cm (surface hoar, facets, and/or crust). However, the stronger mid-pack could act as a slab over weak depth hoar, which comprises the lower third of the snowpack. This is pronounced in shallow areas such as Marmot basin back-country and the Maligne range.
Avalanche Summary
Field team in Whistler Creek reporting no new avalanches in area. Previous activity noted in the Alpine on lee features.
Confidence
Problems
Deep Persistent Slabs
It is possible to trigger deep slabs from shallow snowpack areas. If triggered, these will have severe consequences. Terrain management is critical to a safe day.
Minimize exposure to terrain traps where the consequences of an avalanche could be serious.Be cautious in shallow snowpack areas where triggering is more likely.
Aspects: All aspects.
Elevations: All elevations.
Likelihood
Expected Size
Loose Dry
Little new snow to add to the volume in active loose dry avalanches occurring naturally in the facetted snow from recent cold temps. Ice climbers should consider consequences of an avalanche if climbing in confined gully features
If triggered dry loose point releases can form deeper deposits in terrain traps.
Aspects: All aspects.
