Border Graie Alps

As a consequence of warming, the natural avalanche activity will gradually increase.

As a consequence of warming, the natural avalanche activity will gradually increase.

The fresh wind slabs can still be released in some cases in particular on near-ridge shady slopes and generally at elevated altitudes. Medium-sized avalanches are possible. Avalanches can in isolated cases be triggered in the old snowpack and reach large size. In particular on steep sunny slopes and in starting zones where no previous releases have taken place medium-sized and, in isolated cases, large gliding avalanches and moist snow slides are possible as a consequence of warming during the day. Restraint should be exercised because avalanches can sweep people along and give rise to falls. Backcountry tours and ascents to alpine cabins should be started and concluded early.

Over a wide area 30 to 50 cm of snow, and even more in some localities, fell on Tuesday above approximately 1800 m. The wind slabs are bonding only slowly with the old snowpack on shady slopes at elevated altitudes. The surface of the snowpack will freeze, but a strong crust will not form and will soften during the day. Weak layers exist in the old snowpack in particular on shady slopes.

The spring-like weather conditions will give rise to increasing settling of the snowpack.
