Moderate

Avalanche Summary

Last reported avalanches were from explosive control work on Thursday, producing size 1-2 wind slabs in north facing treeline terrain. Crowns were thin, however wide propagation was reported.

We are still awaiting observations but expect a natural wet avalanche cycle to have occurred during the rapid warming period on Sunday afternoon.

Snowpack Summary

Up to 25 cm of recent snow is settling rapidly and becoming moist or wet in most areas. Dry and wind affected snow may still be found on shady aspects in the alpine.

The recent snow sits over a widespread crust. Below the crust, the snowpack is strong and well bonded.

Weather Summary

Sunday night

Partly cloudy. 30 to 50 km/h west ridgetop wind. Freezing level 2500 m. Treeline temperature 0 °C.

Monday

A mix of sun and cloud. 30 to 40 km/h west ridgetop wind. Freezing level 2700 m. Treeline temperature +9 °C.

Tuesday

Freezing levels remain around 2500 m overnight and through Tuesday. A mix of sun and cloud. 40 to 50 km/h southwest ridgetop wind. Treeline temperature +7 °C.

Wednesday

Overnight freezing levels drop to 1300 m. 10 to 15 cm snowfall by morning then flurries bringing another 5 cm through the day. 30 to 40 km/h southwest ridgetop wind. Treeline temperature -4 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.
  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.

Avalanche Problems

Loose Wet

Loose wet avalanches are most likely on steep, sun affected slopes. Avalanches may initiate easily on the smooth crust below.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 1.5
