Low avalanche danger but isolated danger zones due to drifts
Older drifts lie deposited atop a generally stable and melt-freeze encrusted snowpack surface, mostly on E/W facing slopes. The bonding to the old snowpack is generally good and inside the fresh snow are only isolated weak layers. The base is moist, tends to glide over smooth ground.
On Thursday barrier clouds will lodge against the northern flank of the Alps, minor snowfall from them is possible, but intermittent sunshine is still expected. On the southern flank of the Alps, sunnier in the morning than in the north; in afternoon from the west, clouds will move in. The NW winds will be brisk on the eastern rim of the Alps, elsewhere only moderate. At 2000 m: +1 degree.
Low avalanche danger but isolated danger zones due to drifts
Low avalanche danger, but above the treeline on E/S facing slopes isolated snowdrift masses in transitions from steep gullies and bowls and behind discontinuities can trigger as slab avalanches. Isolated naturally triggered glide-snow avalanches possible. Avoid zones below glide cracks.
On Friday, milder, moderate westerly winds, clouds passing through. The snowdrift problem will gradually recede, avalanche danger level will remain low.
