Caution: increasing danger in daytime cycle of avalanche danger

Caution: increasing danger in daytime cycle of avalanche danger

Avalanche danger will increase slightly above 1600m. The small amounts of fresh snow will often fall on ground which is bare of snow. At high altitudes, it consolidated well with the moist old snowpack surface. In regions with rain-impact, small wet-snow avalanches are possible on steep slopes in all aspects which have not yet discharged. In isolated cases, small glide-snow avalanches are possible.

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 and weakens further.

A cold front will bring dense cloud cover and initially heavy rainfall, snowfall level dropping to 1500m. In the latter part of the night, precipiation will slacken off significantly. Clouds and intermittent precipitation on Thursday will limit visibility in the mountains. Snowfall level at 1700m. At 2000m: -1 degree. Light to moderate westerly winds.

On Friday, conditions will be variable, cool, with intermittent snowfall down to 1600m. Regionally, avalanche danger can increase somewhat at high altitudes.
