Use extra caution as you gain elevation. rider triggerable wind slab can still be found on north and east aspects in higher terrain.

    Rider triggerable wind slabs can be found in exposed treeline and alpine features on North and east aspects. 

    In deeper snowpack areas on the west side of the forecast region storm slabs may form at treeline and above. Storm slabs produce up to size 2 avalanches.

Snowpack Summary

A crust will likely form on all aspects treeline and below as well as solar aspects in the alpine. below this new crust up to 20cm of dry snow sits on the early February crust. This is followed by another 30 to 50cm of dry snow and then the late January crust which is at least 10cm thick and extends to mountain tops on all aspects.

The mid and lower snow pack is well settled but shallow at low elevations leaving many hazards just below the surface.

Confidence

Low - Uncertainty is due to limitations in the field data.

Weather Forecast

Sunday night: light snow, up to 5cm. Moderate to strong south winds and freezing levels around 1300m.

Monday: light precipitation bringing up to 10cm of snow and light to moderate southwest winds. freezing level around 1300 m.

Tuesday: light snow throughout the day bringing up to 15cm. Moderate southwest winds and freezing levels around 1100m.

Wednesday: light to moderate west winds and light precipitation. Freezing level rising to 2500m.

Avalanche Summary

On Thursday our field team observed several loose wet avalanches up to size 1.5 in the treeline and above. Ski cutting produced small wet slabs running on a crust down 15cm at 1100m.

Terrain and Travel

  • Avoid freshly wind loaded features, especially near ridge crests, roll-overs and in steep terrain.
  • Watch for fresh storm slabs building throughout the day.
