Lo esencial

Expect new slabs from the recent snowfall. Observe for slab properties and the bond with the snow below before committing into avalanche terrain. The sun may shine, which will weaken the snow and increase the likelihood of triggering avalanches.

Problemas de aludes

  • Storm Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible - Likely
    Tamaño
    1–2.5
    Up to 45 cm of recent snowfall at high elevations has produced new storm slabs. The snow fell with strong southwest winds so expect thicker slabs in lee features.

  • Loose Wet

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–2
    The sun will rapidly weaken the snow surface. Expect loose wet avalanches, particularly on steep southerly terrain and near rocks. Watch your overhead exposure, as they can grow and become large and destructive.

Confidence

Moderate - Timing or intensity of solar radiation is uncertain

Weather Forecast

SUNDAY: A mix of sun and cloud, light northeast winds, treeline temperature 0 C, freezing level 1400 m.MONDAY: Cloudy with snowfall, accumulation 10 to 15 cm, light west winds, treeline temperature -2 C, freezing level 1100 m.TUESDAY: Mostly cloudy, light west winds, treeline temperature -2 C, freezing level 1200 m.

Avalanche Summary

We have received very little information on avalanche activity for this region.  From the little we have heard, skiers could easily trigger small loose wet avalanches on Friday.  The rain at lower elevations and snow at higher elevations should mean that the likelihood of triggering avalanches is on the rise.We would very much appreciate it if you spend a moment to submit any observations you have to the Mountain Information Network here, even if it is just a photo. Thanks!

Snowpack Summary

Up to 45 mm of rain fell at lower elevations on Friday night.  Some or all of this precipitation likely fell as snow at higher elevations, building reactive storm slabs that sit on a thick crust.Below tree line, a spring snowpack exists. Rain has saturated the upper snowpack. Forecasted rain will continue this trend.
