Manage your terrain choices during period of sun and warming temperatures.

Expect the chance of triggering an avalanche to increase on solar aspects.

Avalanche Summary

On Sunday a large (size 2) avalanche was triggered by a snowmobiler near Mt. Tod. Check out the MIN report here. On Saturday 1 small (size 1) natural avalanche was reported near Vernon in steep unsupported terrain. On Friday many small to large (size 1 to 2) wind slab avalanches were triggered by explosive control work in the region.

Snowpack Summary

35 to 50 cm of snow overlies a supportive crust.

Two weak layers of surface hoar and/or faceted grains associated with a crust from late January and mid-February may be found 80 to 100 cm deep.

The mid and lower snowpack is well settled and strong.

Weather Summary

Monday night

Partly cloudy with 1 to 3 cm of snow. 20 to 30 km/h northwest ridgetop wind. Treeline temperature -8 °C.

Tuesday

Mix of sun and cloud. 10 to 20 km/h west ridgetop wind. Treeline temperature -6 °C.

Wednesday

Sunny with clouds increasing through the day. 30 to 40 km/h south ridgetop wind. Treeline temperature -5 °C.

Thursday

Cloudy with 2 to 5 cm of snow. 30 to 50 km/h southwest ridgetop winds. Treeline temperature -5 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Even brief periods of direct sun could produce natural avalanches.
  • Carefully evaluate steep lines for wind slabs.
  • Investigate the bond of the recent snow before committing to your line.
  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.

Avalanche Problems

Storm Slabs

Storm slabs are beginning to bond. New wind slabs have formed on north aspect terrain near ridge crests. Expect during periods of clearing and sun that the upper snowpack will rapidly settle, increasing the chances of human triggering.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2
