Strong southwesterly winds may form reactive wind slabs on lee features. Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.

Avalanche Summary
No new avalanches were reported on Tuesday.
Snowpack Summary
Around 10 cm of recent snow and strong southerly winds are building fresh wind slabs on lee features.
These wind slabs are sitting on a variety of wind affected surfaces and/or a crust that extends up to at least 1200 m on all aspects. Below this, the mid-pack is generally well-settled and strong in most areas.
Weak facets (sugary snow) exist at the base of the snowpack, especially in more shallow snowpack areas such as the Inland areas.
Terrain and Travel
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Wind slabs may be poorly bonded to the underlying crust.
- Wind slabs are most reactive during their formation.
- Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
- Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
Problems
Wind Slabs
Strong southwesterly winds may form reactive wind slabs on lee features.
Whumpfing, cracking, and hollow sounds are all signs of instability that should cause you to back off into lower angle or less wind-loaded terrain.
Aspects: North, North East, East, South East.
