Nock Mountains

First fine-weather day after heavy snowfall

First fine-weather day after heavy snowfall

Avalanche danger is considerable. On very steep slopes, naturally triggered small-to-medium loose-snow and slab avalanches are possible. Most danger zones occur in W/S/E facing terrain, both near to and distant from ridgelines and in steep gullies in all aspects. Avalanche prone locations are often difficult to recognize on-site. Backcountry freeriders and skiers require ample experience to assess these dangers in outlying terrain.

Heavy snowfall Monday afternoon plus strong E/NE winds have generated snowdrifts, deposited on S/W facing slopes. On Tuesday the drifts were blanketed by fresher snow, without wind. All in all, since Monday and Tuesday’s fresh snowfall there has been up to 40 cm of fresh snow registered. Gullies and leeward bowls are filled to the brim with drifts. Bonding between the fresh snow (fell at mild temperatures) and the cold snow beneath it is poor.

Wednesday will be very sunny following early morning fogbanks on the valley floors. Excellent visibility in the dry winter air. Winds will be light. At 2000 m: -1 degree. On Thursday, initially still sunshine, but visibility will deteriorate from the north gradually. In the Lungau Nockberge, brisk NW winds will arise. At 2000 m: -7 degrees.

Rising northerly foehn wind will transport the snow anew.
