Expect varying conditions with elevation and aspect. Assess for the bond of the new snow before committing to high-consequence terrain.

High

Avalanche Summary

The past few days saw widespread small (size 1) storm slab and loose avalanches in alpine terrain. Riders could trigger similar avalanches on Saturday. Loose wet avalanches are also expected on sun-exposed slopes during the heat of the day.

Please consider submitting your observations to the MIN if you head to the backcountry.

Snowpack Summary

20 to 30 cm of recent snow accumulated over the past few days, with rain below 1000 to 1500 m. This new snow sits on surface hoar crystals that overly soft or wind affect snow on northerly alpine terrain or a hard melt-freeze crust elsewhere. Thicker deposits may be found in lee terrain features near ridgetop. Sun-exposed slopes are likely to moisten with daytime heating.

Weak faceted grains above a hard crust that formed in early February is buried around 100 to 150 cm deep. The layer is strengthening and is currently dormant.

The remainder of the snowpack is settled.

Weather Summary

Friday Night

Clear skies. 10 to 20 km/h northwest ridgetop wind. Treeline temperature -5 °C.

Saturday

Partly cloudy. 10 to 20 km/h west ridgetop wind. Treeline temperature -3 °C. Freezing level 1600 m.

Sunday

Clear skies. 10 to 20 km/h north ridgetop wind. Treeline temperature -1 °C. Freezing level 1800 m.

Monday

Clear skies. 10 to 20 km/h west ridgetop wind. Treeline temperature 4 °C. Freezing level 2500 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Closely monitor how the new snow is bonding to the old surface.
  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.

Avalanche Problems

Storm Slabs

Recently formed slabs could remain touchy to riders over the weekend. They rest on weak layers on northerly aspects and a hard crust elsewhere. Deeper deposits could be found in lee terrain features near ridgetop.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 1.5

Loose Wet

Wet loose activity on sun-exposed slopes is possible during the heat of the day.

Aspects: South East, South, South West.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 1.5
