As a consequence of new snow and wind a dangerous avalanche situation will prevail. Numerous small and medium-sized dry and wet avalanches are to be expected as a consequence of warming during the day and solar radiation.

As a consequence of new snow and wind a dangerous avalanche situation will prevail. Numerous small and medium-sized dry and wet avalanches are to be expected as a consequence of warming during the day and solar radiation.

Over a wide area 50 to 70 cm of snow fell on Sunday above approximately 1500 m. The northerly foehn wind will transport the new snow significantly. At intermediate and high altitudes the wind slabs will increase in size additionally as the day progresses. High-altitude starting zones will be replenished further. The large quantity of fresh snow as well as the wind slabs can be released easily or naturally. As a consequence of warming during the day and the solar radiation, the likelihood of avalanches being released will increase in particular on very steep sunny slopes. In addition as the day progresses at low and intermediate altitudes, numerous moist and wet avalanches are to be expected. The conditions are unfavourable for ski touring, freeriding and snowshoe hiking.

The new snow remains for the foreseeable future prone to triggering. Sunshine and high temperatures will give rise as the day progresses to rapid moistening of the snowpack in particular on sunny slopes below approximately 2400 m. Especially steep shady slopes high altitudes and the high Alpine regions: Towards its surface, the snowpack is unfavourably layered. Weak layers exist in the old snowpack here. Adjacent to ridgelines and in pass areas as well as at high altitude snow depths vary greatly, depending on the infuence of the wind.

The danger of dry avalanches will decrease gradually. Increase in danger of moist and wet avalanches as a consequence of warming during the day and solar radiation.
