Persistent weak layers
- Above 1,900 m
Caution: weak layers in old snowpack ca trigger in isolated cases
Caution: weak layers in old snowpack ca trigger in isolated cases
Avalanches can be triggered in the weak layers by one sole skier in some places, and grow to medium size. Danger zones occur mostly in transitions from shallow to deeper snow, e.g. at entry points into gullies and bowls, a on very steep shady slopes above 1900m. Attention must be given to the dangers of being swept along and forced to take a fall.
The snowpack is highly diverse over small areas. Below 1600m there is little snow on the ground. Shady slopes: the uppermost part of the snowpack is expansively metamorphosed, there is surface hoar and also faceted crystals. In the lower part of the snowpack there are faceted expansively metamorphosed crystals evident. Sunny slopes: snowpack largely stable, with a crust on the surface.
On Sunday, low-lying high-foglike clouds will persist until midday, reaching to over 2000m. Visibility will be poor. In the Carnic Alps, a bit of snowfall is expected. During the course fo the day clouds will disperse, some sunshine is anticipated in the afternoon hours. At 1000m: +3 degrees at midday; at 2000m: -2 degrees; at 3000m: -7 degrees.

Weak layers in the old snowpack demand caution
