Regions: South Coast.

Give storm slabs a chance to heal to the surface before stepping into bigger terrain. Steep, unsupported, and/or convex features will harbour instability for the longest.

Freezing level to 1200 metres with alpine temperatures around -1.

Avalanche Summary

No recent avalanches have been reported in the region. Looking forward, the focus is on our most recent snow accumulations. It will take some time for recently formed storm slabs to build a solid bond to the previous surface and human triggering potential of these slabs will remain a concern over the short term. Expect to find increasingly thick and reactive storm slabs as you gain elevation into the alpine.

Snowpack Summary

A wide ranging 15-45 cm of new snow covered the region over Thursday and Friday night. Below 1400 metres, this new snow lies over moist or wet snow sitting above a strong and well settled snowpack. Much thicker and more reactive storm slabs are likely to be found at higher elevations. The mid and lower snowpack are well settled and strong throughout the region.

Avalanche Problems

Storm Slabs

Recent strong winds and steady snowfall have formed storm slabs that increase in depth and reactivity with elevation. Expect deeper slabs and touchier conditions on the lee side of wind exposed terrain features.

Dig down and investigate the bond of the recent snow before committing to your line.Be alert to conditions that change with elevation.Be increasingly cautious as you transition into wind affected terrain.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible - Likely

Expected Size: 1 - 3
