Stability has improved on the South Coast, but avoid testing any unsupported wind slabs.

Avalanche Summary
No new avalanches have been observed, but ski cutting in the North Shore mountains on January 1 produced one size 1 wind slab avalanche 10 metres wide and 20 cm deep. Shooting cracks were propagating up to 2 metres ahead of ski tips on wind loaded features, suggesting touchy conditions at the time. While we normally expect a short life span these kinds of storm instabilities on the South Coast, recent cold temperatures may have slowed the strengthening process somewhat.
Snowpack Summary
Approximately 95 cm of well-settled storm snow lies on the surface after a series of storms last week. In the days following the storms, strong northerly winds redistributed loose storm snow into wind slabs behind exposed terrain features, mainly on south to west aspects. These wind slabs have gained considerable strength in recent days but remain a concern over the short term. Aside from possible wind slab instabilities in the upper snowpack, the mid and lower snowpack are considered to be well settled and stable.
