Problemas de aludes

  • Wind Slabs

    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–4
    New wind slabs may develop as cooling temperatures turn rain into snow at higher elevations. Wind transported snow may over load cornices which have become weak from rain and high freezing levels.

  • Loose Wet

    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–4
    Loose wet snow slides may release naturally from steep terrain at treeline and below. Wet slides in motion may gain a lot of mass as they scour isothermal snowpacks down to the ground.

Confidence

Fair - Freezing levels are uncertain on Saturday

Weather Forecast

Overnight and Saturday: The second of three waves of precipitation is expected to make its way to the interior by early morning. Expect 10-15 cms of new snow to fall above 1700 metres elevation combined with moderate winds gusting to strong from the West. Alpine temperatures should drop to about -3.0 overnight and rise to -1.0 during the day.Sunday: Expect a slight cooling trend in the wake of the second wave. The third wave of precipitation should move into the interior by the afternoon, combined with light Southerly winds.Monday: Conditions should start to dry out in the wake of the third wave of precipitation.

Avalanche Summary

No new avalanches reported. Expect loose wet snow releases from steep terrain at treeline and below.

Snowpack Summary

New snow is expected to bond well to the old moist or wet surfaces. Some new wind slabs may develop at higher elevations. Surface crusts may have developed before new snow started to fall, providing a sliding layer for the new snow.
