In sintesi

Continue to assess for wind slabs in exposed, alpine terrain features.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità

    Recently formed wind slabs may remain reactive at higher elevations. Be particularly cautious around corniced ridges, cross-loaded features, and convex rollovers.

Confidence

Moderate

Avalanche Summary

A group of skiers remote-triggered a size 2 avalanche on a wind-loaded convex roll in the Wheaton area on Sunday. Check out the associated MIN here.

If you go into the backcountry, please submit your observations to the Mountain Information Network.

Snowpack Summary

A widespread surface crust likely exists up to roughly 1500 m.

At higher elevations recent snow has been redistributed by winds from various directions. Deeper deposits of wind slabs can be found in exposed terrain.

In some areas, a weak layer of facets or surface hoar may persist, down approximately 50 to 80 cm from the surface.

Weather Summary

Tuesday Night

Partly cloudy. 10 to 30 km/h northeast ridgetop wind. Treeline temperature -3 °C.

Wednesday

Terrain and Travel Advice

  • Be especially cautious as you transition into wind affected terrain.
  • Carefully evaluate steep lines for wind slabs.
  • Back off if you encounter whumpfing, hollow sounds, or shooting cracks.
