Regions

Jasper.

Good skiing in sheltered areas. Heads up for steep terrain that has been loaded by snow transport in the alpine.

Weather Forecast

Seasonal temperatures and no significant winds expected until Thursday night into Friday morning when ~5 to 15 cm is forecasted in the Icefields area with moderate south winds. 

Snowpack Summary

On lee slopes, windslab sits on top of a 5-10cm thick crust between roughly 2100m and 2600m. These slabs may be touchy in cross-loaded areas within the elevation band where the crust exists. Facets are present on top of this crust but the snow appears to be quite well bonded to this layer.

Avalanche Summary

No avalanche patrol today.

Confidence

Timing, track, or intensity of incoming weather system is uncertain on Friday

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind 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.
