Avoid being on, or under steep, sun affected slopes in the afternoon - hazard will peak with strong sunshine and warm temperatures.

Confidence

Moderate

Avalanche Summary

No new avalanches were reported in this region over the past few days. However, field observations are currently very limited.

If you head into the backcountry, please submit any observations or photos to the Mountain Information Network.

Snowpack Summary

Up to 10 cm of moist or wet snow exists on sun affected slopes, and shaded aspects to around 2000 m. This surface snow may not refreeze overnight leading to soft and slushy conditions, ideal for wet snow avalanches. On north facing slopes near ridgelines, deposits of dry snow may be found, affected by the previous strong southwesterly winds.

Weather Summary

Saturday Night

Mostly clear skies. 15-30 km/h west ridgetop wind. Freezing level remains above 2500 m.

Sunday

Mostly sunny. 30-50 km/h southwest ridgetop wind. Treeline temperatures range from +7 to +2 °C. Freezing level drops over the day to 2100 m.

Monday

Mostly cloudy with 5-10 cm of snow. 40-60 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level around 1500 m.

Tuesday

Mostly cloudy with 5-10 cm of snow. 10-20 km/h northerly ridgetop wind. Treeline temperature -3 °C. Freezing level around 1500 m.

Terrain and Travel Advice

  • A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.
  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches
  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

Avalanche Problems

Loose Wet

Expect wet slab and wet loose avalanches to become more likely on steep, sun affected slopes as temperatures rise. Avalanches are expected to initiate easily on the crust below.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Likely

Expected Size: 1 - 1.5
