In sintesi

10-15cm of snow is forecast over the next few days with generally seasonal temperatures.  Areas of hard slabs should be expected in Alpine areas.  Already one near miss on a popular ice climb so be heads up.

Problemi valanghivi

  • Wind Slabs

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

    Hard windslabs should be expected in alpine areas due to recent winds.  If these slabs fail there will not likely be a large avalanche but consequences could be high if one is carried over a cliff or along the rough ground.

Avalanche Summary

A few smaller slabs were observed along east aspects in alpine terrain.  None of these slabs were bigger than sz 1.

Confidence

Poor - Due to the number and quality of field observations

Weather Forecast

Forecasts are calling for 10-18cm of snow over the next 36hours with cooling temperatures and moderate to light winds.  If we get the forecasted snow, the pockets of harder slabs may be tougher to located.

Snowpack Summary

Still below threshold amounts below treeline but as you get closer to treeline and above (mainly above) we are seeing snow begin to accumulate.  Winds over the past few days have created pockets of dense windslabs in alpine areas that are concentrated in gullies, crossloaded features and along ridgelines.  These slabs if they were to be triggerred would likely fail at the interface with the ground.  Unsupported features such as steps between pitches of ice climbs, we well as gullies above and below ice climbs should be treated with caution.  Scramblers should also pay close attention to these pockets of hard slabs along routes.
