In sintesi

Strong winds overnight may have gathered enough of the new snow on leeward slopes to form wind slabs.

These will be easily triggered on the widespread firm crust.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Likely
    Dimensione
    1–1.5

    New snowfall amounts are expected to be small but accompanying strong winds may deposit enough on lee terrain features for the snow to slide on the firm crust below.

  • Cornices

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely
    Dimensione
    1.5–2.5

    Large cornices exist on most ridge crests and may be weak after the recent warm temperatures. Be aware of your overhead hazard and avoid exposure.

Confidence

Moderate

  • We are confident about new snow amounts, but uncertain about whether slabs will form.

Avalanche Summary

Sunshine and warm temperatures triggered a small loose wet avalanche cycle from steep terrain over the weekend.

A widespread, natural avalanche cycle occurred up to size 4.0 on Mar 19-20 during the atmospheric river filling the valley bottoms with huge debris piles in many locations. Check out pics from this exceptional avalanche cycle in the MIN Reports.

Snowpack Summary

Overnight flurries delivered a dusting of snow over a widespread crust. Very high elevation north facing slopes may still hold dry snow.

A thick rain crust from the March atmospheric river sits 20-50cm below the surface.

Below treeline the surface varies from isothermal sticky snow to refrozen tree bombs and huge debris fields from the massive avalanche cycle in March.

Weather Summary

Flurries Monday night into Tuesday & cooler temps, gradual rewarming through the week with freezing levels (FZL) reaching 2600m by the weekend.

Tonight Isolated flurries - 5cm. Low -9°C. Winds W 25 gusting 95 Km/h. Freezing level 800m

Tues Flurries, 5cm. High -7°C. Wind W 20 gusting to 65km/h. FZL 1200m

Wed Sun & cloud no precip. High -4°C. Wind NW light. FZL 1700m

Thur Sun & cloud no precip. High 1°C. FZL 2000m

Terrain and Travel Advice

  • Avoid lee and cross-loaded slopes at alpine and treeline elevations.
  • Avoid travelling on slopes below cornices.
