Weather Forecast

Nocturnal hours: The foehn wind will come to an end, it will be cloudy but dry. Monday daytime: Dry weather, variably cloudy, some sunshine, some fog. At 2000 m: -1 to +2 degrees. Light to moderate easterly winds.

Tendency

Tuesday will be variably cloudy with some precipitation, somewhat cooler. Danger of wet-snow avalanches will recede slightly, otherwise avalanche danger levels are not expected to change significantly.

Avalanche Activity

Main danger: wet-snow/glide-snow avalanches

Small-to-medium glide-snow avalanches are still possible. Caution urged below glide cracks. In very steep terrain, small loose wet-snow avalanches can be expected, these can also be triggered by 1 person in steep terrain. Danger of being swept along and being forced to take a fall should be taken into consideration.

Snowpack Structure

At low and intermediate altitudes the snowpack is thoroughly wet down to the ground. Clouds passing through will hamper nocturnal longwave outgoing radiation, a crust capable of bearing loads cannot form easily. Warmth is making the snowpack weaker, esp. in wind-protected terrain. Warm ground and the wet snowpack base reinforce the gliding movements of the entire snowpack. Very little snow on the ground below 1400 m.
