Avalanche Activity

Some fresh snow and storm winds have created moderate avalanche danger due to snowdrifts extending down to wooded zones.

Above about 1400 m avalanche danger is moderate. Avalanche prone locations are where fresh snowdrifts have accumulated behind protruberances, particularly in N/E/S aspects, where slab avalanches can be triggered. Also in forest lanes and open spaces distant from ridgelines, there are danger zones. Freshly formed cornices are instable.

Snowpack Structure

Due to fresh snow and stormy NW winds, trigger-sensitive snowdrifts have accumulated. Weak layers are the soft layers inside the freshly generated drifts and, on shady slopes, there are weak layers in the old snow. The snowpack is highly varied: windblown spots are often adjacent to wind-loaded cavities full of drifts.

Weather Synopsis

Whereas in the Northern Alps there will still be dense clouds accumulating, south of the Mur-Mürz rift there will be sunshine and it will be dry. Winds will persist at strong to storm strength from the northwest. Temperatures will rise. At 2000 m: -4 degrees at midday.

Tendency

On Wednesday, sunny mountain weather by and large, and higher temperatures. Due to the warmth, increasingly frequent naturally triggered avalanches can be expected. The snowdrift problem will diminish.
