In sintesi

Trees may offer cover from the wind, but they may also harbor a recently buried weak layer.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Likely
    Dimensione
    1–2

    New snow and wind are forming fresh and reactive wind slabs in leeward terrain features at upper elevations.

  • Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible - Likely
    Dimensione
    1–2.5

    Recent snow is likely to remain triggerable by riders where it sits over a weak layer of surface hoar, 50 to 70 cm deep.

Confidence

Moderate

Avalanche Summary

Observations have been limited. There have been no recent reports of avalanches in the region.

If you are getting out in the backcountry, consider sharing your observations on the Mountain Information Network (MIN)!

Snowpack Summary

A new storm arrives with cold, low density snow and strong wind. It falls over 50 to 70 cm from earlier this week. In wind-sheltered areas, this recent snow sits over a weak layer of feathery surface hoar crystals, making for a poor bond.

The mid snowpack contains a crust with small facets above it, but does not present a problem at this time.

The snowpack is around 1 m deep at treeline, tapering quickly with elevation.

Weather Summary

Friday night
Increasing cloud. 30 km/h southeast ridgetop wind. Treeline temperature -15 °C.

Saturday
Cloudy. 10 to 15 cm of snow. 60 to 80 km/h southwest ridgetop wind. Treeline temperature -9 °C.

Sunday
Mostly cloudy. 10 to 15 cm of snow. 60 to 70 km/h southwest ridgetop wind. Treeline temperature -1 °C.

Monday
Mostly cloudy. 15 to 20 mm of mixed precipitation. 50 km/h southwest ridgetop wind. Treeline temperature +1 °C. Freezing level 1800 m.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Be aware of the potential for large avalanches due to buried surface hoar.
  • Any steep opening in the trees should be treated as suspect right now.
  • Choose simple, low-angle terrain without steep convex rolls.
