    Shifting winds have created slabs on a variety of aspects in wind-loaded terrain.

Terrain and Travel Advice

  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Avoid terrain traps such as gullies and cliffs where the consequence of any avalanche could be serious.
  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.

Confidence

Moderate

Avalanche Summary

On Friday, signs of instability and evidence of wind-loaded were observed at treeline and above.

Wind slabs at upper elevations will continue to be the main concern on Sunday. Be especially cautious during periods of strong sun.

Snowpack Summary

Up to 20 cm of new snow arrived Friday night. Shifting winds have redistributed this snow into wind slabs on various aspects in exposed areas.

This new snow overlies a sun crust on steep south-facing slopes, faceted snow or surface hoar in sheltered areas, and wind-affected surfaces in exposed areas.

The mid and lower snowpack is well consolidated, with several well-bonded crusts scattered throughout.

Snow depth has been reported as 330 cm at 1700 m, tapering quickly at lower elevations below treeline.

Watch this week's North Shore Conditions for more info.
