    Storm snow and previous southwest winds have built stubborn wind slabs at higher elevations. Investigate how slabs are bonding to the underlying surfaces before committing to your line.

Moderate

Avalanche Summary

No recent avalanches have been reported in the region.

Snowpack Summary

5 to 15 cm of recent snow overlies a widespread crust at treeline and below. At the highest elevations, the snow buried old wind affected surfaces.

The mid and lower snowpack are generally well consolidated, and likely still moist from the recent rain. Conditions remain rugged at lower elevations, with a shallow snowpack.

Weather Summary

Monday Night

Mostly clear skies. 25 to 40 km/h northwest ridgetop wind. Treeline temperature -10 °C. Freezing levels drop to valley bottom.

Tuesday

Increasing clouds. 20 to 30 km/h southwest ridgetop wind. Treeline temperature -10 °C. Freezing level hovers around 500 m.

Heavy snowfall begins Tuesday evening.

Wednesday

Cloudy with snow switching to rain, accumulation 30 to 50 cm above the rain-snow line. Freezing level rises from 500 m to 1500 m. 70 to 90 km/h southwest ridgetop wind. Treeline temperature -2 °C. 

Thursday

Cloudy with 2 to 10 cm of snow. 20 to 30 km/h southwest ridgetop wind. Treeline temperature -7 °C. Freezing level hovers around 600 m.

Terrain and Travel Advice

  • Be especially cautious as you transition into wind affected terrain.
  • Wind slabs may be poorly bonded to the underlying crust.
