Continually assess conditions as you gain elevation. Larger and more reactive storm slabs will be found at higher elevations.

Avoid lee and cross loaded slopes.

Confidence

Moderate

Avalanche Summary

Over the past few days numerous small natural and skier triggered wind slabs have been observed in immediate lee features. Several small natural cornice falls have also been reported.

Snowpack Summary

Up to 70 cm of recent storm snow with strong to extreme southerly winds has likely formed wind slab on west through east aspects at upper elevations. These winds have also scoured exposed windward slopes. As the freezing level falls a new crust will form on all aspects at treeline and below.

A crust from early April can be found down 50 to 80 cm on all solar aspects and at treeline and below on north facing terrain. Below this crust the snowpack is generally well settled.

Weather Summary

Sunday Night

Cloudy with up to 5 cm of new snow expected. Moderate southwest winds and a low of -6°C at 1800 m.

Monday

Mostly cloudy with flurries bringing up to a few cm of new snow. Light to moderate southerly winds and a high of -3°C at 1800 m.

Tuesday

Mostly cloudy with 5 to 10 cm of new snow possible. Moderate southerly winds and a high of -3°C at 1800 m.

Wednesday

Mostly sunny with the possibility of light flurries bringing trace amounts of new snow. Light westerly winds and a high of -3°C at 1800 m.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Avoid lee and cross-loaded terrain.
  • Seek out sheltered terrain where new snow hasn't been wind-affected.
  • Minimize your exposure time below cornices.

Avalanche Problems

Storm Slabs

Rider triggerable wind and storm slab will likely still be found at all elevations with the largest and most reactive being found on west through east aspects at treeline and above.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Likely
