Be alert to conditions that change with aspect and elevation.

Heightened avalanche conditions exist on specific terrain features.

Carefully assess your local conditions and consider how the weather affects the snowpack.




Avalanche Summary

Small solar-triggered point releases were reported out of steep terrain Monday and Tuesday. A small (size 1) skier-triggered wind slab was also observed on convoluted alpine terrain. Over the past weekend, storm slabs and loose dry avalanches were reported (up to size 1-2) mostly artificially triggered by skiers and explosives.

Snowpack Summary

A moist or crusty surface has likely formed on southerly aspects and below 1000 m. 15 to 30 cm of recent snow has seen modest wind effect, with wind loading mostly isolated to immediate lees of ridgetop. Recent snow appears to be bonding well to underlying surfaces including melt-freeze crusts.

The middle of the snowpack is strong and bonded. At the bottom of the snowpack, a layer of weak facets remains present and continues to be monitored for signs of reactivity.

Weather Summary

A vigorous frontal band will arrive on Wednesday evening. Wet, warm & windy conditions are expected to ease on Friday before the following warm front impacts the region over the weekend.

Tuesday night

Mostly cloudy with clear periods. Light southwest wind. Alpine low -8 °C. Freezing level at valley bottom.


Mostly cloudy. Isolated flurries. Light southwest wind increasing to moderate. Alpine high -4 °C. Freezing level rises to 1300 m.


Snow. Local amount 15-20 cm. Strong southwest wind gusting 60 km/h. Alpine high -2 °C. Freezing level rises to 1500 m.


Mostly cloudy. Isolated flurries up to 5 cm. Moderate southwest wind gusting 50 km/h. Alpine high -3 °C. Freezing level rises to 1400 m.

Terrain and Travel Advice

  • Be carefull around freshly wind loaded features.
  • Remember that in the spring strong solar radiation and warm temperatures can weaken the snow in a matter of minutes.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
  • Be alert to conditions that change with aspect and elevation.


Loose Wet

An icon showing Loose Wet

Loose wet avalanches will become increasingly likely on steep solar aspects as the surface becomes moist or wet with strong sun.

Aspects: South East, South, South West.

Elevations: All elevations.



Expected Size

1 - 1.5

Wind Slabs

An icon showing Wind Slabs

Recent snow has seen mild wind effect. Wind slabs have been soft and specific to immediate lees of ridge crests. They may remain rider-triggerable, especially on steep, unsupported and/or convex terrain features.

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

Elevations: Alpine.


Unlikely - Possible

Expected Size

1 - 2
