Northern Lepontine Alps

The wind slabs of the last few days must be evaluated with care and prudence in high Alpine regions.

The wind slabs of the last few days must be evaluated with care and prudence in high Alpine regions.

Wind slabs are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain. They remain for the foreseeable future prone to triggering in particular on steep shady slopes. The wind slabs can be released by large loads in particular. The avalanche prone locations are to be found especially in gullies and bowls above approximately 2400 m and at transitions from a shallow to a deep snowpack.

As a consequence of high temperatures and solar radiation the snowpack settled during the last few days. Snow depths vary greatly at intermediate and high altitudes, depending on the infuence of the wind. Fresh wind slabs have settled a little. Gradual decrease in avalanche danger as the temperature drops.

The avalanche danger will persist. Evening: Some new snow to intermediate altitudes.
