It's the end of the season, for our forecasts and for what remains of the snowpack...

Watch for overhanging cornices, and changing surface conditions on warm and sunny days.




Avalanche Summary

No new avalanches have been reported this week. Evidence of cornice failures was reported on Thursday. While they didn't trigger an avalanche on the slope below they are hazardous on their own.

Looking forward cornice falls remain possible, and wet avalanches are a concern on steep slopes on sunny and warm days like Sunday and Monday.

Snowpack Summary

The snowpack has continued to shrink from rain and mild temperatures. Some eastern faces in the Tablelands remain above threshold (for riding and avalanche activity). A weak crust likely sits at the surface with partially refrozen snow below. Weakened cornices sit above north and east facing terrain features. Check out the photos below from Friday.

Southern terrain including the Lewis Hills holds only bare rock or very minimal amounts of remaining snow, well below threshold for riding.

Terrain and Travel Advice

  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • If it's deep enough to ride, it's deep enough to slide (avalanche).
  • A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.

Use caution travelling near cornices, on ridgelines and on the slope below. Cornice falls are unpredictable.

Aspects: North, North East, East, North West.

Elevations: Alpine.



Expected Size

1 - 2

Loose Wet

An icon showing Loose Wet

Wet loose avalanches are most likely on steep sun affected slopes. Keep an eye on surface conditions and back off these slopes when they become moist or wet.

Aspects: East, South East.

Elevations: Alpine, Treeline.



Expected Size

1 - 1.5
