Regions: Jasper.

Watch for the avalanche hazard to rise with the freezing levels this weekend.

Road closures are possible on Highway 93N and Maligne Road, Saturday through Monday.

Check Alberta 511 for updates.

Weather Forecast

Rising freezing levels, poor over night recovery, and light precip are in store for the weekend. Moderate to strong winds are also forecast for the alpine.

Snowpack Summary

0-10cm low density new snow, redistributed by strong SW winds, overlies a sun crust at all elevations and a melt-freeze crust up to 2100m on all aspects

Snow pack below 1700m is either wet or refrozen depending on the time of day and the solar input.

Avalanche Summary

The widespread wet loose avalanche cycle has tapered off thanks to good overnight freezes and colder temps. A few wind slabs up to size 1.5 have been noted in the alpine.

Avalanche Problems

Wind Slabs

Previous strong SW winds, with new snow, has formed wind slabs at TL and in the ALP.

  • Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
  • Use caution in lee areas. Recent wind loading have created wind slabs.

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

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2

Loose Wet

The significance of this problem will vary widely depending on aspect, elevation, and the time of day. Pay attention to how good the overnight freeze is, as well as how quickly things are warming up.

  • Use extra caution on solar slopes or if the snow is moist or wet.

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

Elevations: All elevations.

Likelihood: Possible - Likely

Expected Size: 1 - 2
