New snow and strong winds will increase the potential for avalanches.
Look for areas of soft snow, sheltered from the wind to ride.

Avalanche Summary
No new avalanches have been recently reported.
The picture below shows current features of concern - We expect new and reactive wind slabs to form with Tuesday night's snowfall and wind.
Snowpack Summary
10 to 20 cm of new snow now hides the old heavily wind affected snow, with some slopes stripped from recent strong southerly winds.
In sheltered areas, a crust from early December sits below 30 to 50 cm of settling snow. This layer has produced avalanche activity and shown reactivity on testing. However, observations are limited in this region and the reactivity or distribution of this is not well understood.
There are no current deeper layers of concern.
Data is very limited in this region, please submit MIN reports if you head into the mountains. Any data or photos are helpful!

Terrain and Travel Advice
- Expect slab conditions to change drastically as you move into wind-exposed terrain.
- Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
- Recent wind has varied in direction, so watch for wind slabs on all aspects.
Problems
Wind Slabs
New snow may build more reactive deposits. Slabs may fail on the early December crust and facets producing larger avalanches.Watch for hollow or 'drum like' sounding snow near ridgelines and mid slope rollovers.
Aspects: North, North East, East, South East, South West, West, North West.
