Regions

Jasper, Brazeau, Churchill, Cirrus-Wilson, Fryatt, Icefields, Maligne, Marmot, Miette Lake, Pyramid.

Strong winds with new snow starting to trickle in on Wednesday will increase avalanche hazard in alpine and at exposed tree line.
The hazard will increase further as a significant snowstorm begins Wednesday night, bringing upwards of 30 cm of snow by Friday.

Confidence

Moderate

  • We are uncertain due to the timing, track, and intensity of the incoming weather system.

Avalanche Summary

On Monday, local ski resort saw a skier triggered windslab, size 2, 2480m, North aspect, 40cm deep and 300m long. Their explosive control work had a similar result on the adjacent slope.
Icefield's patrol only had 30% visibility, snowing actively, with 20cm of new snow South of Parkers ridge. No naturals were observed but gusty conditions noted with windslabs forming.

Snowpack Summary

15-30cm of soft snow in sheltered locations sits on various melt freeze crusts and older wind affected snow, or a patchy surface hoar layer below treeline. The midpack is generally dense and well consolidated with basal facets in thin snowpack areas.

Weather Summary

Wednesday
Flurries. Accumulation: 8 cm. Alpine temperature: High -8 °C. Ridge wind southwest: 30 km/h gusting to 75 km/h. Freezing level at valley bottom.

Thursday

Snow. Accumulation: 21 cm. Alpine temperature: Low -12 °C, High -8 °C. Ridge wind west: 35 km/h gusting to 95 km/h. Freezing level at valley bottom.

Friday

Mainly cloudy with isolated flurries. Precipitation: Trace. Alpine temperature: Low -17 °C, High -13 °C. Ridge wind west: 15 km/h gusting to 45 km/h. Freezing level at valley bottom.

Terrain and Travel Advice

  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.

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.
