Regions: South Coast.

Riding conditions are improving but don't let your guard down, especially in wind loaded terrain.

Confidence

Moderate - Due to the number and quality of field observations

Weather Forecast

A brief break Friday before the snow starts again on Saturday. FRIDAY: clearing, light southeast winds, freezing level 1000m, SATURDAY: light snow, moderate southwest winds, freezing level 1000m. SUNDAY: up to 10cm new snow, light southwest winds, freezing level 800m.

Avalanche Summary

Natural avalanche activity is expected to slow as conditions continue to dry out and cool off over the next couple of days.

Snowpack Summary

Over a meter of new snow has fallen in the high alpine since the weekend. Bellow 2200m the more recent storm snow overlies a saturated snowpack and perhaps a fresh rain crust.  Southwesterly winds are loading lee features at ridgetop. Below tree-line snow depths are probably still below threshold for avalanches although I expect we may be crossing that line soon.

Avalanche Problems

Storm Slabs

Slab avalanches are still possible, especially in steep unsupported terrain and wind loaded features.
If you are increasing your exposure to avalanche terrain, do it gradually as you gather information.>Avoid freshly wind loaded features.>

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 2 - 5
