Points saillants

High avalanche danger. Avoid avalanche terrain and exposure to runout zones.

Problèmes avalancheux

  • Storm Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Very Likely
    Taille
    1.5–2.5

    Large storm slabs are expected to be reactive throughout the forecast period.

  • Loose Wet

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Very Likely
    Taille
    1.5–2.5

    Expect wet loose avalanches to be reactive where precipitation falls as rain.

Confidence

Moderate

  • We are uncertain due to rapidly changing freezing levels.

Avalanche Summary

No recent avalanche activity has been reported.

Expect widespread natural avalanches during the forecast period.

Snowpack Summary

Up to 30 cm of snow is expected to fall overnight, with another 30 to 35 mm of precipitation on Monday. In the south of the region, freezing levels will reach 2000 m. This falls on a thin crust, and possibly wind-affected snow at higher elevations.

A thick, widespread crust is buried in early march is 40 to 60 cm deep. Below it, the snowpack is generally settled and well-bonded.

Terrain and Travel Advice

  • Be alert to changing conditions throughout the day.
  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • As the storm slab problem worsens, the easy solution is to choose more conservative terrain.
  • Loose avalanches may start small, but they can grow and push you into dangerous terrain.
