Regions

Kananaskis.

The winds continue to rage in the alpine. Right now the winds are the major concern. Be aware of the wind direction and how it may have impacted the slopes you have chosen to travel through. Ice Climbers, watch for hardslabs. MM

Confidence

Good

Weather Forecast

Extreme winds (100km/hr +) are forecasted for the next 36hrs in the alpine. Treeline winds will be considerably less, but still in the range for slab development. The winds will be out of the west. The temps will still be warmer than usual, especially in the Bow Valley and front range. No significant precip is forecasted until after the week-end.

Avalanche Summary

No new avalanches noted

Snowpack Summary

Windslabs continue to develop in the ALP & TL with the high winds. Visible signs of widespread crossloading at all elevations. Front ranges are seeing rapid sublimation with wind.

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.
