    Storm slabs may linger anywhere they rest on buried surface hoar. The most likely terrain this exists in is wind-sheltered openings, particularly in the lower alpine.

Confidence

Moderate

Avalanche Summary

No new avalanches were reported on Monday. Looking forward, the most likely areas for riders to trigger avalanches are in lower alpine slopes, where pockets of buried surface hoar may exist under a slab of snow from last weekend.

Observations remain limited in this region. If you head into the backcountry, please post to the Mountain Information Network.

Snowpack Summary

Around 10 to 30 cm of snow overlies a hard melt-freeze crust and perhaps isolated pockets of feathery surface hoar in wind-sheltered openings at treeline and alpine elevations. The crust is on the snow surface up to around 1300 m. Westerly wind may have formed deeper snow deposits in lee terrain features in wind-exposed terrain.

There are currently no deeper layers of concern.

Weather Summary

Tuesday Night

Mostly clear skies. 10 to 20 km/h west ridgetop wind. Treeline temperature -8 °C.

Mostly cloudy with 1 to 3 cm of snow. 10 to 20 km/h southwest ridgetop wind. Treeline temperature -3 °C.

Thursday

Mix of sun and cloud with trace snow. 10 to 20 km/h south ridgetop wind. Treeline temperature -5 °C.

Friday

Cloudy with 1 to 3 cm of snow. 20 to 30 km/h south ridgetop wind. Treeline temperature -6 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Closely monitor how the new snow is bonding to the old surface.
  • Be careful as you transition into wind-affected terrain.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
