Regions

Kananaskis.

Daily forecasts to start Nov 15th. Still EARLY season out there right now with only isolated opportunities for turns. Remain positive and let the snow continue to fall!!!

Confidence

Fair - Due to limited field observations

Weather Forecast

Cool temps forecast to continue over the next few days with only minimal precipitation expected. Winds to remain at light to moderate at treeline and above.

Avalanche Summary

Recent slab activity up to sz 2 on N and E aspects failing on a Nov Crust just above the ground. Numerous loose dry slides on all aspects up to sz 1

Snowpack Summary

HS at the Burstall pass plot at 2200m is 60cm. Smowpack observations are limited at this time.

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.

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.
