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

It's a good time to consider stepping out into more complex terrain.

Riding conditions will be best once the surface crust has softened on sun-affected slopes.

Confidence

High

Avalanche Summary

On Sunday pinwheeling was observed on steep sun-affected slopes. We expect small loose wet avalanches to have occurred from steep, rocky features.

If you are headed into the backcountry please consider submitting a MIN report.

Snowpack Summary

Strong sunshine and warm temperatures are expected to break down the surface crust at low elevations and on steep sun-affected slopes into the alpine. Snow on north facing alpine slopes will likely remain loose and dry.

The mid and lower snowpack is dense and well-settled with no current concerns.

Weather Summary

Monday Night

Clear skies. 10 to 20 km/h northwest ridgetop wind. Treeline temperature 0 °C.

Tuesday

Sunny. 20 to 30 km/h northwest ridgetop wind. Treeline temperature 7 °C. Freezing level 3000 m.

Wednesday

Sunny with afternoon cloud. 40 to 50 km/h west ridgetop wind. Treeline temperature 1 °C. Freezing level starts at 2500 m and drops over the day.

Thursday

Cloudy with 10 to 15 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperatures around -3 °C. Freeing levels remain around 500 m.

Terrain and Travel Advice

  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • Travel early on sun-exposed slopes before cornices weaken with daytime warming.

Avalanche Problems

Loose Wet

Loose wet avalanches are most likely on steep, south facing slopes in the afternoon - especially near rocks where warming will be most intense.

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

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 1.5
