Regions

Jasper.

A significant amount of storm snow hit the region.

In many areas, the storm snow remains uncohesive and light with minimal slab development over the new interface.

Have a safe, fun, cold smoke, blower Christmas everyone!

Weather Forecast

Broken skies and calm winds continue through the region. Cold daytime temperatures floating around -12.

Snowpack Summary

45cms of mostly undisturbed storm snow blanketing the region. This overlies a mosaic of buried wind slabs and facetted weak layers. Basal layers continue to develop into larger facets and depth hoar. Surface hoar growing in sheltered areas.

Avalanche Summary

No new avalanches observed or reported

Problems

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.

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.
