Regions: South Coast.

Continually assess conditions as you travel and watch out for isolated (wind) slabs.

Confidence

Moderate - Due to the number of field observations

Avalanche Summary

No new avalanches observed.

Snowpack Summary

The mountains of the South Coast region received 15-20cm of snow Sunday-Monday. The new snow came in wet and heavy (especially in the North Shore mountains) and bonded well to 15 cm of settling snow from Friday's storm.  Watch out for small wind slabs on north-facing slopes in the lee of exposed features. Friday's snow buried a variable interface composed of faceted (sugary) snow and old hard wind slabs (especially at higher elevations). Recent reports suggest the snow has bonded well to this interface. The mid and lower snowpack are well settled and stable.

Avalanche Problems

Wind Slabs

Be on the lookout for small pockets of wind slab on northerly aspects (from the past storm) and  also on southerly aspects (from recent 'reverse loading' by outflow winds).
Use caution in lee areas. Recent wind loading have created wind slabs.Be careful with wind loaded pockets, especially near ridge crests and roll-overs.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2
