Points saillants

Newly formed storm slabs will become larger and easier to trigger throughout the day.

Make conservative terrain choices and avoid overhead hazard.

    15 to 30 cm of new snow and strong wind will form storm slabs that are reactive to human triggers.

Confidence

Moderate

  • We are uncertain about forecast snowfall amounts.

Avalanche Summary

Human triggered avalanches will become increasingly likely throughout the day on Wednesday.

Snowpack Summary

Forecast snow and wind are expected to form touchy storm slabs overlying persistent weak layers.

At treeline and above, this layer is primarily a hard crust with weak facets above and/or below.

In sheltered treeline locations and below, this layer may be a combination of hard crust and/or surface hoar.

Cornices are reported to be large and looming. Be mindful of them overhead or when travelling on ridge tops.

The mid/lower snowpack is generally well settled and strong.

Weather Summary

Tuesday Night
Mostly cloudy. 5 to 15 cm of snow. 50 km/h south ridgetop wind. Treeline temperature -2 °C. Freezing level 1300 m.

Wednesday
Cloudy. 10 to 20 cm of snow; with another 5 to 15 cm overnight. 45 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level 1300 m.

Thursday
Cloudy. 3 to 10 cm of snow. 45 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1500 m.

Friday
Cloudy. 30 to 40 cm of snow above 1600 m (rain below). 60 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level 1900 m.

Terrain and Travel Advice

  • Make conservative terrain choices and avoid overhead hazard.
  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • Be aware of the potential for larger than expected storm slabs due to buried surface hoar.
  • Use small, low consequence slopes to test the bond of the new snow.
  • Watch for signs of instability like whumpfing, hollow sounds, shooting cracks, or recent avalanches.
