Regions: South Coast.

New slabs may form over the day. Assess for slab formation and the bond to the underlying crust before committing to large terrain features.

Confidence

Moderate - Forecast snowfall amounts are uncertain.

Weather Forecast

MONDAY NIGHT: Cloudy with snowfall, accumulation 2 to 5 cm, 20 km/h southeast wind, treeline temperature -2 C.

TUESDAY: Cloudy with snowfall, accumulation 10 to 20 cm with local amounts up to 30 cm possible, 30 to 40 km/h southeast wind, treeline temperature -5 C.

WEDNESDAY: Early-morning snowfall then a mix of sun and cloud, accumulation 5 to 10 cm, 20 km/h east wind, treeline temperature -3 C.

THURSDAY: Mix of sun and cloud with no precipitation, 10 to 20 km/h northeast wind, treeline temperature -3 C.

Avalanche Summary

No recent avalanches were observed in the region. Looking forward, riders could trigger new wind slabs that form over the day on Tuesday. The new snow may not bond to the underlying crust and could slide easily. Best to stay well back of cornices too, as they are very large at this time of year.

Observations are limited at this time of year, so please consider posting to the Mountain Information Network.

Snowpack Summary

Variable amounts of new snow will accumulate onto a hard melt-freeze crust. The snow may slide easily as dry loose or storm slabs. Southeast wind could produce new wind slabs in lee terrain features. Remember that cornices are very large at this time of year.

The remainder of the snowpack is strong, consisting of hard snow and melt-freeze crusts.

Terrain and Travel

  • Watch for fresh storm slabs building throughout the day.
  • Carefully evaluate steep lines for wind slabs.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.

Avalanche Problems

Storm Slabs

New storm and wind slabs may form over the day as snow accumulates with southeast wind. The new snow may not bond well to the underlying crust. Assess for slab properties and bonding to the crust prior to committing to large terrain features.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible - Likely

Expected Size: 1 - 2
