Avoid wind loaded features and overhead hazard

New snow and strong wind will build wind slabs throughout the day, These slabs could release naturally

Confidence

High

Avalanche Summary

On Friday our field team observed several small wind slab avalanches that released naturally during the day. These avalanches were on north and east aspects.

Check out their Mountain Information Network report for more details.

Snowpack Summary

Up to 25 cm of snow could fall throughout the day on Saturday with strong to extreme southwest wind forming deeper deposits on north and east facing terrain. This new snow will fall on a crust on all aspects and elevations.

The snowpack varies greatly in depth from 10 to 30 cm in exposed terrain to nearly 3 meters in wind loaded features on east aspects. In sheltered terrain at 500 m above sea level there is an average of 110 cm.

The mid and lower snowpack is generally dense and well consolidated.

Weather Summary

Friday Night

Cloudy with 10 to 15 cm of snow. 20 to 40 km/h southwest ridgetop wind  with gusts up to 80 km/h. Treeline temperature -3 °C.

Saturday

Cloudy with up to 10 cm of snow. 40 to 60 km/h southwest ridgetop wind  with gusts up to 100 to 140 km/h. Treeline temperature -8 °C.

Sunday

Mostly cloudy with 5 to 10 cm of snow possible. 20 to 40 km/h southwest ridgetop wind with gusts up to 60 km/h. Treeline temperature -6 °C.

Monday

Mix of sun and cloud with up to 5 cm of snow. 30 to 50 km/h west ridgetop wind. Treeline temperature -10 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Avoid freshly wind-loaded terrain features.
  • Be especially cautious as you transition into wind-affected terrain.
  • Seek out sheltered terrain where new snow hasn't been affected by wind.
  • Closely monitor how the new snow is bonding to the crust.

Avalanche Problems

Wind Slabs

New snow and wind will form wind slabs throughout the day on Saturday. These slabs could be touchy as they likely won’t bond well to the underlying crust.

Aspects: North, North East, East, North West.

Elevations: Alpine, Treeline.

Likelihood: Very Likely

Expected Size: 1 - 3
