Lo esencial

Sunshine can give a false sense of security, but dangerous avalanche conditions remain.

Rider-triggered avalanches are likely, so choose conservative terrain and route selection.

Problemas de aludes

  • Wind Slabs

    Probabilidad
    Possible - Likely
    Tamaño
    1–2

    Recent snowfall and wind have created wind slab, which may remain reactive on lee slopes and cross-loaded features. Recent strong wind means wind slabs may be found farther downslope than expected.

  • Loose Wet

    Direct sun on fresh dry snow may initiate loose avalanches on steep slopes. Avoid exposure to overhead hazards when solar radiation is strong.

Confidence

Moderate

  • We are uncertain due to a limited number of field observations.
  • We are uncertain about how the timing or intensity of solar radiation will affect the snowpack.

Avalanche Summary

There were no new avalanches to report in the last few days, but poor visibility restricted field observations since Tuesday.

If you are heading into the backcountry, please share any observations with the Mountain Information Network.

Snowpack Summary

20 to 40 cm of recent snow overlies wind-affected surfaces or old settling storm snow. Strong to extreme westerly wind redistributed this new snow, farther downslope than normal, forming slabs down to treeline.

This overlies old settling snow in wind-sheltered terrain, hard wind-affected snow in open areas and/or a solid melt-freeze crust in wind-exposed terrain.

The remainder of the snowpack is consolidated with no layers of concern.

Weather Summary

Friday Night

Partly cloudy. 1 to 3 cm of snow. 50 km/h west ridgetop wind. Treeline temperature -14 °C.

Saturday

Mostly sunny. 60 km/h west ridgetop wind. Treeline temperature -12 °C.

Sunday

Mostly sunny. 70 km/h west ridgetop wind. Treeline temperature -6 °C.

Monday

Mostly cloudy. 60 km/h west ridgetop wind. Treeline temperature -3 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
  • Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
