Weather Forecast

Saturday night: flurries bringing trace amounts of new snow with moderate westerly winds. Low of -3 at 1200m.

Sunday: mostly cloudy with up to 10cm of snow. Freezing level around 900 m. Light southerly winds.

Avalanche Summary

Natural and human triggered wet loose and dry loose avalanches up to size 1.5 have been observed in the region over the past few days. We suspect storm and wind slab avalanches will be reported on Saturday.

Snowpack Summary

Wind slab can be found on northerly aspects at higher elevations. The upper snowpack contains several crust layers that can likely be found on all aspects and elevations except high north terrain. The snowpack is considered well-settled and strong below these crusts. 

Terrain and Travel

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Use ridges or ribs to avoid areas of wind loaded snow.

Avalanche Problems

Wind Slabs

New wind slabs will likely be found near ridge crests at higher elevations on northerly aspects.

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

Elevations: Alpine, Treeline.
