Persistent weak layers
- Above 2,200 m
Caution: weak layers in old snowpack can trigger in isolated cases
Caution: weak layers in old snowpack can 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 mostlyn on W/N/E facing slopes in transitions from shallow to deeper snow, e.g. at entry points into gullies and bowls, a on very steep shady slopes above 2200m. Attention must be given to the dangers of being swept along and forced to take a fall.
W/N/E facing slopes above 2200m: in the lowermost part of the snowpack are faceted expansively metamorphosed weak layers evident. The uppermost part of the snowpack is expansively metamorphosed, there is surface hoar and also faceted crystals. Sunny slopes below 2800m: the snowpack is largely stable, with a crust on the surface. Over small areas it is highly diverse. Below 1700m there is hardly any snow on the ground.
On Wednesday, generally gray skies, cloud and fog, some light snow snowers in the mountains, only minor amounts expected. Sunshine will be rare. Light to moderate southerly winds (30 km/hr). At 1000m: 0 degrees; at 2000m: -3 degrees; at 3000m: -8 degrees. Source: GeoSphere Austria
Weak layers in the old snowpack demand caution
