Avalanche Summary

No new avalanches were reported in this region on Monday.

Snowpack Summary

A hard crust now caps the snowpack up to the tops of the North Shore mountains. High elevation terrain in other parts of the region could have up to 50 cm of recent snow, likely heavily wind affected. However there are no observations to confirm alpine conditions.

Terrain and Travel

  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • Be careful as you transition into wind affected terrain.
  • Extra caution is needed around cornices under the current conditions.

Avalanche Problems
