    Moderate danger

Windslabs have formed in strong SW-W winds last days. A clear sign of instability was seen in Siglufjörður and Ólafsfj. where slabs are on top of firn which is covered with surface hoar. Also a weak layer of graupel. Increasing instability expected in the warm SW-winds early monday morning.

The avalanche bulletin is at a regional scale. It does not necessarily represent avalanche danger in urban areas.

Avalanche problems in the area

Snow layers and snow cover

Windslabs have formed in strong SW-W winds the last few days. Snowpits from both Siglufjörður and Ólafsfjörður showed buried surface hoar between the old firn and the new wind slab which gave sudden planar failure with easy load and propagation. A thin layer of hail which failed easily was also spotted just below the surface crust. A similar weak layer was found in a snowpit at Öxnadalsheiði on the 8th. The stiff snow on top seemed then to protect it from stress and decrease the likelihood of collapse. Today the snowpit from the same spot in Siglufjörður didn"t show the surface hoar nor the windslab. But a layer of graupel was spotted below two layers of new snow. The graupel failed with easy load. PST gave fracture at 55 cm of 100.

Recent avalanches

Three slabs were spotted in Hlíðarfjall on Saturday after strong SW-W winds lately
