In sintesi

Watch out for isolated wind slabs in the alpine. The surface snow may moisten quickly and form loose wet avalanches during sunny periods.

Problemi valanghivi

  • Wind Slabs

    Probabilità

    Dimensione

    Recent snow in the alpine has been redistributed by strong westerly wind. Use caution in lee terrain features adjacent to ridges, where deposits may be most reactive.

  • Loose Wet

    The recent snow will moisten quickly on southerly aspects under sunny skies. Loose wet avalanches can become dangerous quickly, so use added caution when the sun is out and during the heat of the day.

Avalanche Summary

Explosives triggered small cornice chunks on northerly ridges on Monday. The chunks did not trigger slabs on the slopes below.If you have any recent observations during your travels, we would greatly appreciate it if you posted a photo or any other information to the Mountain Information Network (MIN). Thanks!

Snowpack Summary

Around 15 cm of recent snow fell with strong westerly wind, forming wind slabs in lee terrain features at alpine elevations. This snow may overly weak and feathery surface hoar in isolated areas. Heat from the sun and an increasing freezing level will likely moisten alpine snow on southerly aspects. Below around 1800 m, the snowpack is consolidated and rapidly melting.
