Fresh snowdrifts in foehn lanes. Beware daytime danger cycle.

Avalanche danger is low. On Sunday in foehn lanes, strong-to-stormy high altitude winds will arise, esp. on north-facing slopes small snowdrift accumulations will be generated. Isolated triggerings of small avalanches can be released by persons in extremely steep terrain. Apart from the danger of being buried in snow masses, the risks of being swept along and forced to take a fall require adequate consideration. Due to warmth and solar radiation, moist slids and small wet-snow avalanches are possible esp. on steep sunny slopes during the course of the day. On steep grass-covered slopes with ample snow or on smooth ground, increasingly frequent small glide-snow avalanches are possible.

The below-average old snowpack is all-in-all well consolidate and generally stable. On shady slopes, the uppermost layers are often still powdery. Overnight on sunny slopes and at lower altitudes, a melt-freeze crust forms, often breakable crusts. With daytime warming, the snowpack forfeits its firmness and becomes weaker as it becomes wetter.

High air pressure will generate dry mountain weather, the southerly air current will bring mild temperatures, zero-degree level at just under 3000m. Southerly winds at high altitudes and in the foehn lanes will be a perturbance. In the afternoon, more cloud cover will move in, hamper gradually the sun. On Sunday night some rainfall, snowfall above 1800m. At 2000m: +5 degrees. Moderate to brisk southerly winds, in the well-known foehn lanes blowing at strong to storm strength.

As clouds move in on Sunday night, the snowpack surface may consolidate somewhat. Below 1800m light rainfall will weaken the snowpack.
