    Cornices along ridgelines are large and looming. They weaken with progressive warming and could fail at any time.

Avalanche Summary

A few size 2 cornice falls were observed on east-facing slopes north of Nelson on Tuesday. Wet loose avalanches (size 1 to 2) also occurred across the region during the warm, sunny weather on Sunday and Monday.

Snowpack Summary

Northerly alpine slopes may still hold 10 to 15 cm of soft, dry snow. Elsewhere, a thick crust covers the surface and may soften with daytime warming. There are no concerning layers deeper in the snowpack, and the snow is melting rapidly at lower elevations.

Terrain and Travel Advice

  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Carefully evaluate big and steep terrain features before committing to them.
