In sintesi

Another beautiful day to recreate in the mountains. Expecting some light snow, and gusty upper elevation winds leading into the weekend.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    1–2
    Expect windslabs in the alpine and at open treeline. The cold has reduced slab conductivity, and the probability for long propagations. Caution is still warranted on exposed or extreme terrain features.

  • Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely
    Dimensione
    1.5–3
    A cold, facetting, and structurally weak slab up to 80cm thick overlies faceted crystals (well developed in shallow areas).

Weather Forecast

Weather over the next week should remain a stable pattern. Cool overnight and temps rising to single digits over the day. Chance of scattered flurries with little accumulations. Temps and freezing levels will rise through the week, coupled with increased solar radiation, so expect the need apply some sunscreen over your day.

Snowpack Summary

Surface facetting has weakened the upper snowpack through the forecast region. Where the snow is shallow (like BTL), there is little support underfoot. The upper snowpack is generally 50 to 80 cm, over the seasonally persistent instability. Wind slabs and wind effect in open areas in the alpine and treeline elevations.

Avalanche Summary

No new avalanche activity observed or reported.
