Icy conditions. Snowdrift patches at high altitudes.
Avalanche danger is low, but freshly generated snowdrift patches require attentiveness. Danger zones occur mostly in gullies and bowls, also behind abrupt drops in the terrain in extended easterly aspects. The risks of falling on hardened icy ridgeline surfaces require attentiveness.
In E/S aspects, fresh snow is being transported by stormy NW winds distant from ridgelines and deposited in gullies and bowls in extended eastern aspects where they lie atop melt-freeze crusts or an icy old snowpack surface or snowdrifts from previous days - bonding is poor. Elsewhere the snowpack surface is encrusted, particularly in exposed zones it is hard and icy. Where there was no snow prior to the precipitation, the fresh fallen snow is insufficient for backcountry tours.
On Tuesday the precipitation will lessen but in the barrier cloud regions snow showers and stormy NW winds will still prevail. In the afternoon, tapering off but winds will still be stormy. On the southern flank of the Alps, northerly foehn wind will disperse the clouds, some sunshine is expected. At 2000m: -11 degrres; at 1500m: -6 degrees. On Wednesday a warm front will bring gray skies, some snowfall above 1300 m on the northern flank of the Alps. Winds will slacken off. Also Thursday will be gray, but very mild.
Avalanche danger levels will not change significantly.
