Points saillants

Continuously assess conditions as you gain elevation. Winter conditions persist at higher elevations.

New wind slabs could form throughout the day where precipitation falls as snow.

Avalanche Summary

On Tuesday a natural cornice fall resulted in a size two avalanche on a northwest aspect.

If you have any recent photos or observations, please submit them to the Mountain Information Network, observations are limited in the spring.

Snowpack Summary

Up to 15 cm of new snow may accumulate on all aspects at higher elevations. The largest deposits will be found on north and east aspects in the alpine. This new snow may not bond well to the underlying crust. Below treeline rain will keep the snow surface wet or moist where snow still exists. Most below treeline terrain is already snow free.

Weather Summary

Wednesday Night

Mostly cloudy with trace to 2 cm of new snow at treeline and above. 10 to 30 km/h southwest alpine wind. Freezing level falling to 1300 m.

Thursday

Cloudy with up to 5 cm of new snow at treeline and above. 10 to 20 km/h south alpine wind.  Freezing level rising to 1800 m.

Friday

Cloudy with up to 5 cm of new snow in high alpine terrain. 5 to 15 km/h variable alpine wind. Freezing level rising to 2100 m.

Saturday

Cloudy with 5 cm of new snow at treeline and above. 25 to 50 km/h south alpine wind. Freezing level rising to 1800 m.

Terrain and Travel Advice

  • Be carefull around freshly wind loaded features.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • Expect shallow snow cover that barely covers ground roughness.
  • Minimize your exposure time below cornices.
  • The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
