Regions

Jasper.

Some great skiing to be had in Jasper right now, but it is still a good idea to gather info on smaller terrain features before committing to the bigger lines.

Weather Forecast

Cool temps to remain until the weekend, with minimal wind and light scattered flurries. Daytime heating and solar radiation will increase towards the weekend, and will increase the avalanche danger.

Snowpack Summary

The recent storm snow appears to be bonding well to previous surfaces, and has been subjected to minimal wind affect. At lower elevations, this storm snow is sitting on a weak and faceted midpack.  There is a lot of snow that is plastered to steep rocky terrain that will most likely sluff once the sun hits it in the afternoon. 

Avalanche Summary

Monday's explosive control work produced some size 3 soft slabs in the Icefields and Maligne lake alpine areas. They slid on the storm snow interface. A few dusted the highway. Gullies above polar circus were 85% cleaned out with control work.  No new slab avalanches were observed or reported today.�

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.
