Daytime increase of avalanche danger.

Daytime increase of avalanche danger.

Avalanche danger is low in early morning, then rises during the afternoon above 1600m to moderate. On steep slopes below 2600m which have not yet discharged, medium-sized wet-snow avalanches can trigger naturally or be triggered by persons. Also isolated small-to-medium glide-snow avalanches are possible. In high-alpine zones, fresh snowdrift accumulations require attentiveness, most of them are small but often easily triggered. Danger zones occur in gullies, bowls, behind protruberances in the terrain and on steep shady slopes above 2600m. Isolated small-to-medium avalanches can be triggered by winter sports enthusiasts in the old snow. Avalanche prone locations lie in seldom-tracked shady terrain and are difficult to recognize.

During mild nights of clear skies accompanied by showeres, the snowpack can freeze only slightly and in some places form a melt-freeze crust capable of bearing loads. There is little snow on the ground at high altitudes. Through higher daytime temperatures and solar radiation, the crust then softens rapidly and the snowpack loses its firmness. Beneath the melt-freeze crust the snowpack is thoroughly wet up to high altitudes. Especially in the Silvretta region on high-altitude very steep shady slopes there are still unfavorable intermediate layers evident inside the old snowpack.

Variably cloudy, dry nighttime skies. Easter Monday will be pleasant in the morning, remain dry with high clouds above summit level. In the afternoon, convective cloud build-up, visibility will deteriorate, tendency towards showers will increase (snowfall level for snow showers at 2600m). At 2000m: 0 to 6 degrees. Light to moderate-strength southerly winds.

Avalanche danger will increase inside the daytime danger cycle on Wednesday. Starting Thursday, instable conditions, precipitation. Regionally avalanche danger can increase somewhat.
