Good

Weather Forecast

The light to moderate NW winds are forecast to continue and a warm subtropical air mass is moving into the region.  Clear skies are forecast and temps are expected to increase with a freezing level at 2200m forecast for Sunday.  Watch for decreases in stability on solar aspects.

Avalanche Summary

A few isolated loose dry avalanches from steeper terrain.

Snowpack Summary

Little Change over the past 24hrs.  An additional 3cm of snow overnight give us up to 18cm of HST in some treeline and alpine areas.  This snow has settled rapidly under the influence of the warm temps and is bonding poorly to the underlying hard slabs in many areas.  This layer will likely be touchy for another day or before it starts to setlle and bond better.

Problems

Wind Slabs

An icon showing Wind Slabs
Last weeks wind slabs are now buried by the dribs and drabs of snow we have received over the past week.  Watch for thin weak areas surrounding these slabs,
Be aware of thin areas that may propagate to deeper instabilites.>Avoid unsupported slopes.>

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

Elevations: Alpine, Treeline.

Likelihood

Unlikely - Possible

Expected Size

1 - 4

Loose Dry

An icon showing Loose Dry
Steep un-skiable terrain in Alpine areas, especially on more northern aspects.
Be cautious of sluffing in steep terrain.>Finish ice climbs early in the day before the temperature rises.>

Aspects: North, North East.

Elevations: Alpine.
