Northern Lepontine Alps

The wind slabs of the last few days must be evaluated with care and prudence in high Alpine regions. Moist and wet avalanches are possible as a consequence of warming.

Fresh wind slabs are bonding only slowly with the old snowpack in particular on steep shady slopes above approximately 2500 m. Snow depths vary greatly at intermediate and high altitudes, depending on the infuence of the wind. Sunshine and high temperatures will give rise as the day progresses to increasing moistening of the snowpack in particular on sunny slopes at low and intermediate altitudes.

The wind slabs of the last few days must be evaluated with care and prudence in high Alpine regions. Moist and wet avalanches are possible as a consequence of warming.

The wind slabs can be released by a single winter sport participant. The avalanche prone locations are to be found in particular in gullies and bowls above approximately 2500 m and at transitions from a shallow to a deep snowpack. In particular in steep rocky terrain and on very steep grassy slopes moist and wet avalanches are possible as a consequence of warming during the day. The avalanche prone locations for wet avalanches are to be found in particular below approximately 2300 m.
