Regions: Jasper.

Excellent skiing can be found at tree line and below. Watch for hazards in the alpine such as cornices and recently formed wind slabs.

Weather Forecast

Friday: Cloudy with sunny periods and isolated flurries. High -9. Wind northwest: 15 km/h gusting to 60 km/h

Saturday: Cloudy with scattered flurries. 4cm.  Low -27C, High -12C. Ridge wind light to 20 km/h.

Sunday: A mix of sun and cloud. Low -29 °C, High -23 °C. Light Ridge Winds.

Snowpack Summary

40-60cm with minimal wind effect. This new snow overlies surface facetting, previous wind effect and surface hoar depending on location.  Well settled mid-pack characteristic for the region except in typical shallow locations. Variable HS (90-200cm) throughout the area.

Avalanche Summary

A determined avalanche control team worked hard Tuesday to produced a few good results, up to size 2.5 on a very stubborn storm interface in low elevation targets with several large triggers. No new avalanches observed since avalanche control on Tuesday.

Avalanche Problems

Wind Slabs

Light to moderate W-SW winds are redistributing snow in the high alpine.

  • Be cautious as you transition into wind affected terrain.
  • Avoid exposure to overhead avalanche terrain during periods of moderate to intense transport.

Aspects: North, North East, East, South East, North West.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 2.5

Loose Dry

Steep and rocky terrain.

  • Be careful of loose dry power sluffing in steep terrain.
  • Avoid travelling on ledges and cliffs where sluffing may have severe consequences.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Likely

Expected Size: 1 - 2
