Regions: South Coast Inland.

Don't let your guard down with the sunny weather and fresh snow. Take a cautious approach towards more aggressive terrain - especially steep, wind-affected terrain.

Confidence

Moderate - Due to the number of field observations

Avalanche Summary

Little activity has been reported lately, although there are not many observers out there right now. Small wind slabs are the most likely type of avalanche over the next few days.

Snowpack Summary

Approximately 30-50 cm of new snow now sits on top of a rain crust that formed during the wet weather in late November. The crust is reported to be thick (15 cm) below treeline and thin (2 cm) in the alpine. Southerly winds have blown snow around in exposed areas creating drifts and scoured areas. Stubborn wind slabs have formed near ridge crests and lee features.Tree line snow depths are approximately 110 cm throughout the region.

Avalanche Problems

Wind Slabs

Small wind slabs are possible in steep terrain behind ridge lines. On steep slopes, the new snow may not bond well to the underlying crust.

Be alert to changing snow conditions, especially where the snow firms up or sounds hollow.Use ridges or ribs to avoid pockets of wind loaded snow.Use increased caution in lee areas. Recent snowfall and wind loading have created wind slabs.
