Beware wet-snow and snowdrifts in high-alpine terrain

Beware wet-snow and snowdrifts in high-alpine terrain

Naturally triggered wet-snow avalanches will increase with the daytime danger cycle. Wet-snow avalanches can be triggered by one winter sports enthusiast and grow to medium size. These avalanche prone locations are located particularly on very steep slopes below 2800m. Fresh snowdrift accumulations can be triggered by one sole skier on very steep shady slopes above 2800m. Such danger zones occur esp. in ridgeline terrain, in gullies and in bowls.

Weather conditions below 2800m are leading 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. High-alpine zones: Due to fresh fallen snow and often strong southerly winds, small new snowdrift accumulations will be generated. Nocturnal outgoing longwave radiation is severely reduced, the snowpack hardly freezes, then soften rapidly in the morning hours. On steep sunny slopes below 1900m there is hardly any snow on the ground.

Apart from high-altitude cirrus clouds, frequent sunshine, summits in the clear. During the daytime hours, convective cloud build-up, with tendency towards showers and thunderstorms. Light W/S high-altitude winds. At 2000m: +7 degrees.Source: GeoSource Austria
