Dusting of new snow over the next 24hrs possible. Emphasis on Dusting. Winds will remain light to moderate out of the SW. Freezing levels forecast to be around 1900m.

Avalanche Summary

A few sz 1 slides out of steep rocky terrain related to daytime heating.

Snowpack Summary

SH continues to grow up to size 5mm in Alpine terrain. Moist snow on solar aspects as high as 2800m by 12:00. MFC up to 3cm thick on the solar aspects but still finding dry powder snow on the north aspects.

Problems

Loose Wet

A few loose wet slides are still being observed from steep solar aspects. Thin rocky areas will be the most likely places to encounter these problems.

Aspects: North, North East, East, South East.

Elevations: All elevations.

Likelihood

Possible - Likely

Expected Size

1 - 3

Deep Persistent Slabs

Aspects: North, North East, East, South East.

Elevations: Alpine, Treeline.

Likelihood

Unlikely - Possible
