On Saturday, furthermore, a low will form over northern Italy and bring much less stable and cooler air masses to Tirol. Mountain weather today: a very beautiful and very warm day in Tirol’s mountains. As of late afternoon, large scale convective cloud, possibly an occasional thunderstorm are expected. Temperature at 2000m: plus 8 to plus 10 degrees; at 3000m: plus 1 degree. Moderate northwesterly winds, later shifting to southwesterly. A wide-ranging exploration in a military helicopter yesterday brought the following results: an extemely high number of naturally triggered loose snow avalanches were counted, also isolated full depth snowslides and slab avalanches. Since snow depths have receded significantly due to the mild weather conditions, only a few of the avalanches reached the valley. Last night was slightly cloudy, enabling the snow cover to give off nocturnal outgoing long wave radiation so that a thin melt-freeze crust could form. Through today’s daytime warming and solar radiation, this crust will rapidly soften over the course of the morning and the snowpack forfeit its firmness. The avalanche danger in Tirol’s backcountry touring regions is subject to a daytime cycle. During the morning hours the danger level is generally moderate, then rises swiftly as the snowpack loses its firmness to level "considerable". Particularly on slopes which have not yet discharged, naturally triggered wet avalanches, full depth snowslides and slab avalanches can be expected. In isolated cases they can attain medium size, even large size. Skiing and freeriding tours in outlying terrain need to be brought to an end early in the day.
