In sintesi

Observations from the region have been extremely limited recently. If you are out in the mountains, please consider posting your observations to the Mountain Information Network and help us improve the bulletin. Click here for more details.

Problemi valanghivi

  • Storm Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Likely - Very Likely
    Dimensione
    1–3
    New snow combined with wind at upper elevations will build reactive storm slabs. Forecast rain to mountaintop on this new snow will make slabs very touchy.

  • Loose Wet

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Likely
    Dimensione
    1–2
    Rain at lower elevations will gradually break down surface crusts and contribute to wet snow sluffing and gathering mass in steep terrain.

Confidence

Low - Due to the number of field observations

Weather Forecast

THURSDAY: Periods of rain, accumulation 16mm / Moderate southeast wind / Alpine temperature 4 / Freezing level 1800mFRIDAY: Rain heavy at times, accumulation 30mm / Moderate to strong southeast wind / Alpine temperature 8 / Freezing level 2000mSATURDAY: Snow, accumulation 20-25cm / Moderate to strong south wind / Alpine temperature 0 / Freezing level 1000m

Avalanche Summary

No new avalanches have been reported recently but observations have been very limited. On Thursday, the main concern is storm and wind slab avalanches where the precipitation is falling as snow. At lower elevations expect small loose snow avalanches to be running in steep terrain on all aspects.

Snowpack Summary

Recent snowpack observations have been very limited and confidence is low. The latest storm Tuesday night through Wednesday brought a mix of rain and snow. In the highest elevations within the region there may be as much as 50cm of snow accumulation. This more than likely sits on a widespread crust on all aspects and elevations except for north facing terrain in the alpine. At lower elevations, rain has saturated an already wet snowpack.
