Lo esencial

Head to high north facing slopes to find the best conditions.

Wet loose avalanches remain possible with warm temperatures and light rain.

Problemas de aludes

  • Cornices

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–2

    Cornices are weak and may break further back on ridgelines than expected. These large loads can trigger buried weak layers on the slope below.

  • Loose Wet

    Tamaño
    1–1.5

    Wet loose avalanches are still possible as temperatures remain high and the snowpack has limited chance of refreezing overnight.

Confidence

Moderate

Avalanche Summary

On Saturday, avalanches were observed to size 1.

On Monday, activity is expected to be limited to small, wet avalanches on steep slopes.

Snowpack Summary

Light snow or rain will fall over either a thin crust or moist snow to 2500 m. High alpine north-facing slopes may still hold dry snow above a thick crust from late March.

The mid and lower snowpack are generally well settled.

Terrain and Travel Advice

  • Cornices often break further back than expected; give them a wide berth when traveling on ridgetops.
  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
