Issued: Mar 30th, 2024 4:00PM

The alpine rating is low, the treeline rating is low, and the below treeline rating is below threshold. Known problems include Cornices and Loose Wet.

A thick surface crust makes for generally safe avalanche conditions but difficult travel. Alpine terrain features with a surviving snowpack are also where you'll find cornices overhead.

Summary

Confidence

Moderate

Avalanche Summary

Early last week, a natural avalanche cycle was reported on north to east aspects in the alpine. Slabs were up to size 2.5 with crowns up to 100 cm deep, sliding on a crust layer. Thank you for the amazing MIN reports! Check out the photos on this one!

Avalanche activity is expected to have subsided with the dryer, cooler conditions this weekend.

Snowpack Summary

The surface of the rain-soaked snowpack is refreezing into a crust under cool temperatures. Rain has washed away the snowpack in many areas. Areas where the snowpack is most likely to have survived include previously wind-loaded leeward terrain features such as north-facing alpine bowls, gullies and ridgelines. These are also the types of features where large cornices loom above.

Weather Summary

Saturday night

Mostly cloudy. Ridgetop wind 30 to 50 km/h south. Alpine temperature 0 C. Freezing level 300 m.

Sunday

Cloudy. Ridgetop wind 10 to 20 km/h southeast. Alpine temperature -1 C. Freezing level 200 m.

Monday

Mostly cloudy. Ridgetop wind 10 to 30 km/h east. Alpine temperature -1 C. Freezing level 200 m.

Tuesday

A mix of sun and cloud. Ridgetop wind 20 to 40 km/h northeast. Alpine temperature +1 C. Freezing level 500 m.

Terrain and Travel Advice

  • Winter conditions may exist in gullies, alpine bowls, and around ridgelines.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • Caution around slopes that are exposed to cornices overhead.
  • Large cornice falls are dangerous on their own.

Problems

Cornices

An icon showing Cornices

Rapid temperature fluctuations may have a destabilizing effect on large, looming cornices. Even small cornice falls can have enough mass to be destructive and deadly.

Aspects: North, North East, East, West, North West.

Elevations: Alpine.

Likelihood

Possible - Likely

Expected Size

1.5 - 2.5

Loose Wet

An icon showing Loose Wet

Loose wet avalanches are possible where the snow surface becomes moist or wet with daytime warming.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood

Unlikely - Possible

Expected Size

1 - 1.5
