Avalanche Summary

We haven't received any recent reports of avalanche activity. Looking forward, treat the new snow with caution, particularly if you find more than 15 cm of new snow.

Snowpack Summary

Anywhere from 5 to 30 cm of snow will accumulate by Thursday afternoon with southwest wind. This snow will build on the 15 to 30 cm of snow that accumulated since Saturday. All this snow sits on a hard melt-freeze crust.

A couple weak layers of surface hoar and/or faceted grains associated with a crust from late January and mid February may be found 40 to 60 cm deep.

The remainder of the snowpack is strong.

Weather Summary

Wednesday Night

Mostly cloudy with 5 to 10 cm of snow. 20 to 30 km/h south ridgetop wind. Treeline temperature -3 °C.

Thursday

Cloudy with 5 to 15 cm of snow and local amounts of up to 25 cm possible. 20 to 30 km/h west ridgetop wind. Treeline temperature -5 °C.

Friday

Partly cloudy. 10 to 20 km/h south ridgetop wind. Treeline temperature -6 °C.

Saturday

Cloudy with 1 to 3 cm of snow. 20 to 30 km/h south ridgetop wind. Treeline temperature -4 °C.

Terrain and Travel Advice

  • Watch for fresh storm slabs building throughout the day.
  • Carefully evaluate steep lines for wind slabs.
  • Investigate the bond of the recent snow before committing to your line.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
