Problèmes avalancheux

  • Cornices

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible
    Taille
    1–5
    Cornices are large and sagging. Recent cornice failures have been triggering slabs on the underlying slopes. Be aware of overhead exposure especially during times of intense solar radiation or rain.

  • Storm Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible
    Taille
    1–4
    Storm slabs up to 40cm thick are present in lee and cross-loaded features at higher elevations. A size 2.0 skier accidental slab avalanche occurred on Tent Ridge on Sunday.

  • Loose Wet

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible
    Taille
    1–5
    As crusts melt with solar radiation, daytime heating and/or rain, wet avalanches are occurring. Be especially cautious in areas that have had little or no overnight freeze. Many slides are failing on the ground and involve the entire snowpack.

Confidence

Fair - Timing, track, or intensity of incoming weather is uncertain

Weather Forecast

Wednesday is likely to bring very strong SW winds, warmer temperatures and rain up to 2100m.

Avalanche Summary

Nothing new, but observation were very limited.

Snowpack Summary

Little change from yesterday. Isolated soft slabs exist in lee and cross-loaded terrain in ALP and TL areas. Crusts dominate all aspects except true North. Solar intensity is melting surface snow on all solar aspects.
