It will remain cool, with repeated light showers. Avalanche danger is not expected to change significantly. Bernhard Anwander Translated by Jeffrey McCabe Trigger-sensitive weak layers at high altitude. Slightly increasing avalanche danger today. 2021-04-17T07:30:00+02:00 2021-04-18T07:30:00+02:00 2 2021-04-17T07:30:00+02:00 2021-04-18T07:30:00+02:00 1 2021-04-17T07:30:00+02:00 2021-04-18T07:30:00+02:00 2200 2 2021-04-17T07:30:00+02:00 2021-04-18T07:30:00+02:00 2200 1 2021-04-17T07:30:00+02:00 2021-04-18T07:30:00+02:00 2200 2 2021-04-17T07:30:00+02:00 2021-04-18T07:30:00+02:00 2200 1 2021-04-17T07:30:00+02:00 2021-04-18T07:30:00+02:00 2200 2 2021-04-17T07:30:00+02:00 2021-04-18T07:30:00+02:00 2200 1 2021-04-17T07:30:00+02:00 2021-04-18T07:30:00+02:00 2200 2 2021-04-17T07:30:00+02:00 2021-04-18T07:30:00+02:00 2200 1 2021-04-17T07:30:00+02:00 2021-04-18T07:30:00+02:00 2200 2 2021-04-17T07:30:00+02:00 2021-04-18T07:30:00+02:00 2200 1 old snow 2200 trigger-sensitive weak layers wet snow warmth, radiation: slight increase of danger Alpine weather forecast (ZAMG-Weather Service Innsbruck) The intermediate high is losing strength. Following a night of clear skies, sunshine and little cloud will reign until midday. In the latter part of the day, heavy cloud cover will move in, veil the peaks. By evening, brief showers can set in. Temperature at 2000 m: -6 degrees. Light to moderate NE winds. Snow cover / General info Intermittently moderate-strength northerly winds have generated new small snowdrifts over the last few days. Older drifts were covered over, making them hard to recognize. Particularly on shady slopes, weak layers in the upper part of the snowpack are prone to triggering. The snowpack on sunny slopes became superficially moist yesterday as a result of solar radiation. During the night due to good outgoing longwave radiation, a melt-freeze crust formed (at intermediate altitudes often capable of bearing loads; at high altitudes mostly breakable) which will soften up during the daytime. On shady slopes the uppermost layers are still powdery. Avalanche danger assessment Avalanche danger is moderate above 2200 m, below that altitude danger is low. Main danger: weak near-surface layers which are prone to triggering. Danger zones occur primarily on shady slopes. Avalanches can trigger especially by large additional loading, e.g. a group not maintaining distances. Also, older (often blanketed) small snowdrift accumulations which formed in the latter part of the week are trigger-sensitive. In high alpine regions the situation is more critical. With daytime warming and solar radiation, small-to-medium moist loose-snow and slab avalanches can be naturally triggered in steep rocky terrain. On steep grassy slopes, especially where recent snowfall has been heaviest, small glide-snow avalanches are possible. Caution is urged near glide cracks.
