Problemi valanghivi

    Wind slabs may be lurking near, or well below, ridge crests. Conditions are highly variable, so be alert to hollow, drummy sounds and changes in the feel of the snow as you travel.

Avalanche Summary

No recent avalanches have been reported.

Snowpack Summary

There is anywhere from 30-150 cm on the ground. Recent northerly outflow winds have scoured upwind slopes back to a firm crust, and created wind slabs on lee aspects. The snowpack is highly variable across different aspects and elevations.Wind slabs could be triggered by the weight of a person, especially where they overlie surface hoar, crusts or facets. The other big story is unusual warming at alpine elevations, which may weaken surface layers, or even wake up deeper snowpack weaknesses. Id take a cautious approach to big/ exposed terrain until winter temperatures return to normal.
