In sintesi

The region is split, with fresh storm slab and loose wet avalanche problems in the south of the region and a well-consolidated snowpack in the north. Saturday's danger ratings are biased to the south of the region.

  • Storm Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Likely
    Dimensione
    1–2
    Fresh storm slabs recently formed on the surface in the south of the region and light new snow inputs are forecast to contribute to the problem. Storm slab danger increases with elevation. This problem is largely absent in the north of the region.

  • Loose Wet

    Probabilità

    Continued potential for loose wet avalanches exists at lower elevations where the surface remains moist from rain and where new snow is moist. This problem is largely absent in the north of the region.

Snowpack Summary

A shift from rain to snow on Thursday saw new snow accumulating above about 1300 metres in the south of the region. The depth of this new snow is heavily elevation dependant, with up to 30 cm accumulated at the highest elevations in the south of the region. The north of the region saw only a trace of new snow accumulate on the surface after the rain subsided. Below the new snow, recent heavy rain eroded snowpack depths significantly, leaving behind a rain-soaked and relatively uniform 90 cm at treeline elevations throughout the region.
