Avalanche Activity

Caution urged towards gliding snow

Dangers focus on very steep grass-covered slopes, where small-to-medium sized glide-snow avalanches can release. Caution urged also in gullies and steep bowls, where slabs can trigger in isolated cases, particularly with additional loading above 2000 m.

Snowpack Structure

Prior to 25 November the ground was bare. Snow further up was 30-60 cm deep in several layers, the most compact on the upper surface. Striking weak layers were not evident. Exposed zones are utterly windblown. Over warm and smooth ground surfaces, the snowpack is gliding.

Weather Synopsis

Wednesday will begin with heavy cloud cover and some snowfall (snowfall level at 1200 m). Soon, dry weather will set in, visibility will improve, some sunshine is expected for a few hours. Westerly winds will be blowing at 20 km/hr. At 1500 m, +2 degrees; at 2000 m, 0 degrees.

Tendency

On Friday little change, with dropping temperatures and some fresh snowfall, but moderate gliding snow activity will persist.
