Weather Forecast

Wind Warning in effect for Kananaskis. The Kananaskis region is likely to see 90 km/h wind gusts once again Tuesday afternoon. 

Snow is on its way with 5cm expected by Tuesday morning with light snow during the day. There is expected to be 35-40cm of snow by Wednesday. This amount of snow, along with strong winds will certainly create an avalanche cycle on Wednesday. If the snow arrives sooner, be prepared for rapid changing avalanche hazard.

Avalanche Summary

Numerous spindrift avalanches over steep lee cliffs were observed throughout Kananaskis due to the very strong westerly winds. One size 1 slab in the Hero knob area at tree line.

Snowpack Summary

Strong winds on Monday has moved snow around to create wind slabs in the Alpine and parts of tree line. Expect new soft slabs to begin developing with the incoming storm and strong winds. These new slabs will not have had time to bond to the strong mid pack. Approach open terrain with caution. The most recent surface hoar can be found at tree line and below and will be buried by the incoming snow. Approach steep open terrain at treeline and below treeline with caution.

Terrain and Travel

  • Avoid areas where the snow feels stiff and/or slabby.
  • Be alert to conditions that change with elevation and wind exposure.
  • Watch for fresh storm slabs building throughout the day.

Avalanche Problems

Storm Slabs

Strong westly winds with the incoming snow will create new storm and wind slabs.
