Regions
Banff Yoho Kootenay.
The new snow is bonding poorly to the old snow and is presently touchy. Storm slabs will likely give way to wind slabs and should stabilize fairly quickly. Watch out for large open areas, or gullied terrain that can gain mass quickly.
Weather Forecast
Cooling night time temperatures and continued light snow and clouds should help stabilize the surface problem fairly quickly.
Snowpack Summary
North aspect snow is soft, cold and well settled with few weak layers of concern. 20-30 cm of new snow is forming a soft slab, often on melt-freeze layers and will take a few days to bond. Expect more new snow and windslabs in the alpine by Friday morning
Avalanche Summary
Poor visibility today - no avalanches noted. The local ski hills reported storm slabs running light but fast at all elevations and exposures..
Problems
Loose Dry
Loose Dry avalanches are the release of dry unconsolidated snow and typically occur within layers of soft snow near the surface of the snowpack. These avalanches start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-dry avalanches include point-release avalanches or sluffs.
Storm Slabs
Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
