Daytime increase of avalanche danger.

On Thursday, instable weather conditions including precipitation. Regionally, avalanche danger can increase somewhat at high altitudes.

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 showers, the snowpack can freeze only slightly and in some places form a melt-freeze crust capable of bearing loads. Through higher daytime temperatures and solar radiation, the crust then softens rapidly and the snowpack loses its firmness. Especially in the Silvretta region on high-altitude very steep shady slopes there are still unfavorable intermediate layers evident inside the old snowpack.

Tonight skies will be dry and only partically cloudy. Wednesday morning will be sunny, accompanied by some clouds. Later on, convective cloud bulid-up will increase and showers or thunderstorms could occur, snowfall level dropping to nearly 2000m. At 2000m: up to 6 degrees. Moderate S/SW winds, brisker later on in thunderstorms.
