Points saillants

Storm snow continues to accumulate atop a widespread crust. Use extra caution around recently wind-loaded terrain.

    Several persistent weak layers of surface hoar, facets, or crusts may be buried in the top meter of the snowpack. Storm slabs could step down to these layers, causing larger-than-expected avalanches.

    Snow since the weekend continues to accumulate atop a widespread crust. Expect slabs to be larger and more likely in wind-loaded terrain.

Confidence

Moderate

  • We are confident the likelihood of avalanches will increase with the forecast weather.
  • We are confident that there are persistent slabs in the snowpack, but uncertain about how likely they are to trigger.

Avalanche Summary

On Monday, riders triggered what they suspect was a large wind slab that ran on a crust near Bralone. Check the MIN report for details.

On Sunday, numerous wind slab avalanches (up to size 2) occurred in exposed terrain across various aspects, along with a few cornice failures.

Snowpack Summary

Roughly 20 cm of storm snow has accumulated since the weekend, accompanied by strong, variable winds at higher elevations. A widespread crust, formed by last weekend's rain, lies just below the new snow. At higher elevations, new snow sits atop a generally settled, well-consolidated upper snowpack.

Variable weak layers buried throughout February may persist roughly 40 to 100 cm below the surface, in northerly high elevation terrain. These layers consist of surface hoar, facets, and/or crusts.

The remaining snowpack appears to be strong and well-bonded.

Weather Summary

Mostly cloudy. 5 to 10 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -11 °C.

Wednesday
Mostly cloudy. 5 to 10 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -11 °C.

Thursday
Mostly cloudy. 10 to 15 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -9 °C.

Friday
Mix of sun and clouds. 1 to 4 cm of snow. 20 km/h southwest ridgetop wind. Treeline temperature -11 °C.

Terrain and Travel Advice

  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
  • Be aware of the potential for large avalanches due to buried weak layers.
