Lo esencial

Watch for localized danger on sun-exposed and wind-loaded slopes.

Problemas de aludes

    Unstable slabs may linger on steep wind-loaded slopes, including the lee sides of ridges and cross-loaded features.

  • Loose Wet

    Periods of sun may trigger natural wet loose avalanches on steep slopes.

Confidence

Moderate

  • We are uncertain about how quickly the snowpack will recover and gain strength.

Avalanche Summary

Several natural and human-triggered storm slabs were reported Wednesday. They were size 1 to 2 and typically 20 to 30 cm thick.

Looking ahead, this storm snow snow will be most concerning on wind-loaded features (north and east aspects) and during times of sun-exposure (south and west aspects).

Snowpack Summary

Tuesday’s storm delivered 15 to 30 cm of new snow at upper elevations with strong south winds. This snow is expected to stabilize quickly, except on wind-loaded and sun-exposed slopes.

This snow fell on a mix of crusts and moist or isothermal snow, depending on aspect and elevation.

The lower snowpack has undergone multiple melt-freeze cycles, forming a mix of crusts and dense rounded snow.

Weather Summary

Wednesday Night

Partly cloudy. 1 to 2 cm of snow in the Duffey and Chilcotin. 30 km/h north ridgetop wind. Treeline temperature -8 °C.

Thursday

Mostly sunny. 20 km/h northwest ridgetop wind. Treeline temperature -3 °C. Freezing level 1500 m.

Friday

Mix of sun and clouds. 10 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1800 m.

Saturday

Mix of sun and clouds. 40 km/h south ridgetop wind. Treeline temperature +1 °C. Freezing level 2000 m.

Terrain and Travel Advice

  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
  • Carefully evaluate steep lines for wind slabs.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
