Upper Passeier Valley

Wind slabs require caution.

Wind slabs require caution.

The somewhat older wind slabs can be released by a single winter sport participant on very steep shady slopes above approximately 2400 m. Avalanches can reach medium size. In high Alpine regions the avalanche prone locations are a little more prevalent. Avalanche prone locations are to be found in gullies and bowls, and behind abrupt changes in the terrain. The wind slabs are to be bypassed as far as possible.

In some cases the various wind slabs have bonded still only poorly together, in particular on shady slopes above approximately 2400 m. In very isolated cases weak layers exist in the old snowpack on very steep shady slopes. This applies in particular on the Main Alpine Ridge. The weather conditions will give rise to gradual moistening of the snowpack over a wide area below approximately 2600 m.

Increase in avalanche danger as a consequence of the precipitation. Over a wide area 10 to 20 cm of snow, and up to 40 cm in some localities, will fall.
