In sintesi

Travel in avalanche terrain that has not seen previous activity is not recommended. While natural triggering has slowed, it is still advisable to avoid overhead hazard during the heat of the day.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible - Likely
    Dimensione
    1–2.5
    Up to 45cm of HST fell through the forecast area. Winds during the storm were from the SW but switched to North Easterly on Sunday.

  • Persistent Slabs

    • Alta quota
    • Limite del bosco

    Dimensione

    Persistent slabs remain a problem. The main concern is for areas exposed to large triggers such as cornices and large South facing alpine terrain exposed to the sun.

Weather Forecast

Temperatures remaining cool, but have the potential to reach fluctuate significantly over the course of the day. Minimal snowfall expected, light winds, and clear skies to continue through to midweek.

Snowpack Summary

Varied storm snow amts: 10-15cm in the Icefields, 40cm near Mt Wilson, and 30cm north of Beauty creek is sitting on the weak and facetted persistent slab at mid snowpack. Reverse loading from a northerly flow has cross-loaded Alpine features.

Avalanche Summary

Avalanche activity has tapered, but we could still see some natural activity in the afternoons from solar triggering.

Confidence

Timing or intensity of solar radiation is uncertain
