Beware snowdrifts in steep shady terrain
Avalanche danger is moderate at higher altitudes, elsewhere danger is low. Older snowdrift accumulations require caution. They occur primarily on ridgeline north-facing slopes and in wind-loaded gullies and bowls. In addition. isolated avalanches can be triggered by large additional loading. Apart from the risks of being buried in snow masses, the danger of being swept along and forced to take a fall require caution. Due to solar radiation, wet slides and small avalanches are possible on very steep sunny slopes.
The fresh snow from the weekend and small snowdrifts generated over the last few days have bonded well with the old snowpack surface. On steep shady slopes, bonding is often only moderate. On steep south-facing slopes there is often a melt-freeze crust capable of bearing loads. The old snowpack is generally well-settled and compact.
Clear and frosty night on Thursday. On Friday, quite sunny with some high-altitude cloudbanks and small convective clouds. Temperature at 2000m: -6 to -1 degree; at 3000m: -11 to -6 degrees. Light-to-moderate northeasterly winds at high altitudes.
Avalanche danger expected to continue diminishing
