In sintesi

If you see greater than 15 cm of new snow, treat the danger as CONSIDERABLE.

Be especially cautious in steep, wind-affected terrain where triggering slabs is most likely.

    New snow and wind on Saturday will form fresh, reactive wind slabs in lee areas.

    Weak layers remain a concern in this region, especially where there is no supportive crust. Layer depth is variable. Areas where the snowpack transitions from thin to thick, and rocky terrain features should be approached cautiously.

Confidence

Moderate

  • We are uncertain about how quickly persistent slabs are gaining strength.
  • We are uncertain about forecast precipitation amounts.

Avalanche Summary

On Wednesday, A few small (size 1) skier-triggered wind slab avalanches were reported on north aspects between 1200 and 1400 meters.

On Thursday, skiers triggered a size 1.5 persistent slab on a NW aspect below terrain in the north of the region. Near Terrace, skiers triggered a size 1 wind slab on a SE aspect at treeline.

We suspect new snow and wind on Saturday will form fresh, reactive wind slabs.

Snowpack Summary

Up to 15 cm of new snow buries surface hoar from recent cold, clear weather. This is sitting on 20 to 50 cm of recent storm snow that is wind-affected in open areas. This snow is sitting on a surface crust below treeline, formed following the March 7 warming event and tapering above 1600 m.

The mid snowpack, down 90 to 130 cm, weak layers of surface hoar, facets and crusts remain a concern, especially where there is no crust above. Triggering of these layers is becoming less likely, but remains at a depth where human triggering is possible.

The remaining snowpack is generally well settled and well bonded.

Weather Summary

Friday Night

Partly cloudy. 1 to 10 cm of snow. 20 to 40 km/h west ridgetop wind. Treeline temperature -9 °C.

Saturday

Mix of sun and clouds. 3 to 4 cm of snow. 30 to 40 km/h west ridgetop wind. Treeline temperature -9 °C.

Sunday

Mostly cloudy. 10 to 15 cm of snow. 40 km/h south ridgetop wind. Treeline temperature -8 °C.

Monday

Mostly cloudy. 15 to 40 cm of snow. 60 km/h southwest ridgetop wind. Treeline temperature -3 °C.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • If triggered, wind slabs may step down to deeper layers, causing larger avalanches.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
