Monregalese Valleys

New snow and wind slabs require caution, in the regions exposed to snowfall in particular on very steep slopes.

New snow and wind slabs require caution, in the regions exposed to snowfall in particular on very steep slopes.

10 to 20 cm of snow, and even more in some localities, will fall until late morning above approximately 2000 m. As a consequence of new snow and strong wind the wind slabs will increase in size additionally. These can be released by a single winter sport participant and reach medium size. This applies in particular adjacent to ridgelines and in gullies and bowls at high altitudes and in high Alpine regions, as well as on wind-loaded slopes. In some places avalanches can be triggered in the old snowpack and reach large size in isolated cases. The current avalanche situation calls for careful route selection.

The fresh snow as well as the wind slabs are bonding poorly with the old snowpack in some places in particular on very steep sunny slopes. Towards its surface, the snowpack is dry; its surface consists of loosely bonded snow. This applies in particular at high altitudes and in high Alpine regions. The spring-like weather conditions gave rise to gradual consolidation of the snowpack in particular on sunny slopes below approximately 2600 m. Weak layers exist in the old snowpack in particular on shady slopes.

Significant increase in danger of moist and wet avalanches as a consequence of warming during the day and solar radiation.
