Regions: East Island, North Island, South Island, Vancouver Island, West Island.

Warm air and sunny skies can rapidly destabilize the snowpack. Use extra caution on sun-exposed slopes during the heat of the day.

Confidence

High

Avalanche Summary

We haven't received any avalanche observations over the past few days.

Looking forward, warm air and sunny skies could initiate a loose wet avalanche cycle in the coming days, particularly on steep sun-exposed slopes.

Snowpack Summary

Around 20 to 40 cm of recent storm snow is consolidating and bonding to the snowpack. Thicker deposits may be found in lee terrain features near ridges due to strong southwest wind. With a rising freezing level and sunny skies, expect sun-exposed slopes and low elevations to have a moist snow surface during the day, which may freezing into a hard melt-freeze crust overnight. A dry snow surface will prevail on shaded aspects at higher elevations.

The middle and lower snowpack are consolidated and strong, containing numerous thick and hard melt-freeze crusts.

Weather Summary

Terrain and Travel Advice

  • Minimize exposure to sun-exposed slopes when the solar radiation is strong.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

Avalanche Problems

Loose Wet

Sunny skies and a rising freezing level could trigger wet loose avalanches. Best to avoid steep sun-exposed slopes during intense sunny periods. The warming could also cause cornices to become fragile.

Aspects: East, South East, South, South West, West.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 2
