Beware wet-snow

Beware wet-snow

Wet-snow avalanches can in isolated cases be triggered by one winter sports enthusiast and grow to medium size. These avalanche prone locations are located particularly on W/N/E-facing slopes. Rainfall is anticipated in the afternoon, thereby the likelihood of triggerings will increase.

Weather conditions have led to the snowpack becoming thoroughly wet, forfeiting firmness of the snowpack. Many wet-snow avalanches have already released, many starting zones have completely discharged, the snowpack is thoroughly wet. Nocturnal outgoing longwave radiation is severely reduced, the snowpack hardly freezes, then soften rapidly in the morning hours. On steep sunny slopes below 1700m there is hardly any snow on the ground.

On Wednesday, instable weather conditions. Following sunny phases during the morning, convective cloud build-up will rapidly generate rain showers, often thunderstorms, during the afternoon. Southerly winds will be mostly light. At 1000m: 16 degrees; at 2000m: +5 degrees. Source: GeoSphere Austria
