Allgäu Alps West

Main danger: persistent weak layer. Heed fresh drifts at high altitudes.

Nocturnal hours: dry and clear skies, winds shifting to NW. Monday: sunny until midday, intensifying NW winds, cloud cover and a cold front moving in during the afternoon, deteriorating conditions by evening: snowfall and strong winds. At 2000 m: -6 degrees. Strong to stormy NW winds.

By early Tuesday morning, 15-20 cm of fresh snow is expected. Strong NW winds will persist, transport the fresh fallen snow. Avalanche danger levels will increase on Monday night.

Main danger: persistent weak layer. Heed fresh drifts at high altitudes.

Amid increasingly strong northwesterly winds, mostly small-sized snowdrift accumulations have been generated which can be triggered even by one sole winter sports enthusiast. Superficial layers in wind-impacted steep terrain, in wind-loaded gullies and bowls and behind abrupt discontinuities in the terrain are often still prone to triggering. Danger zones increase in size and spread with ascending altitude. In addition, on steep, less-tracked shady slopes in high alpine regions or in transitions from shallow to deep snow, deeply embedded layers inside the snowpack are triggerable by large additional loading. As a result of solar radiation and daytime warming, more slides and small-sized loose-snow avalanchs are possible.

As a result of moderate-to-strong NE winds, small snowdrift accumulations have been generated afresh due to moderate-strength NE winds. The new snowdrift masses were often deposited atop surface hoar, particularly at intermediate altitudes. In ridgeline and pass areas, behind abrupt discontinuities in the terrain and in wind-exposed terrain, older snowdrift accumulations occur and are often poorly bonded with the snowpack surface or other intermediate layers. On shady leeward slopes and at low altitudes the fresh snow is often loose. At high altitudes on shady slopes in particular, there are still weak layers inside the snowpack which are not visible to the naked eye. At low and intermediate altitudes the snowpack is generally well consolidated. There is often surface hoar evident, esp. at low and intermediate altitudes.
