Avalanche Activity

Caution: increasing danger in daytime cycle of avalanche danger

Avalanche danger in the morning hours is low, rises during the afternoon hours to moderate above 1600m. On steep slopes in all aspects which have not yet discharged, wet-snow avalanches can release naturally or be triggered by winter sports enthusiasts and, in high altitude zones, grow to medium size. In isolated cases small-to-medium glide-snow avalanches are possible.

Snowpack Structure

During partially cloudy nighttime hours, reduced outgoing longwave radiation, the snowpack can freeze only superficially. With higher daytime temperatures and solar radiation the thin crust swiftly softens and the snowpack loses its firmness.

Weather Forecast

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.

Tendency

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