    • Todas las altitudes

Weather Synopsis

On Monday the peaks will be veiled in clouds and fog, visibility will be severely limited, but next-to-no snowfall is anticipated. The E/N winds will be light, no longer transport the snow. AT 2000 m: -13 degrees; at 3000 m: -17 degrees.

Tendency

The fresh snow will settle noticeably due to solar radiation and higher temperatures on Tuesday. Mostly favourable conditions, despite local danger zones.

Avalanche Activity

Lots of fresh snow in Northern Alps

Avalanche danger above 1500 m is MODERATE, below that altitude danger is LOW. The risks stem mostly from small-to-medium slab avalanches which can trigger even by minimum additional loading. The snowdrifts are lightly covered, no longer easy to recognize. Frequency of danger zones increases with ascending altitude. Naturally triggered small-to-medium loose-snow avalanches and isolated glide-snow avalanches are possible in extremely steep terrain.

Snowpack Structure

Since Friday 20-40 cm of fresh snow has been registered widespread, as much as 50 cm on the northern Alpine rim (Osterhorn Massif). In open terrain, winds from W/NW, on Sunday from N/E intermittently transported the snow. Stability tests show no heightened likelihood to fracture, although a weak layer has developed (cold on warm) inside the mass of fresh snow. Apart from that, blanketed fresh snow is also a potential fracture point. On steep north-facing slopes there is also blanketed surface hoar. At low altitudes and on steep sunny slopes up to intermediate altiudes, the fresh snow fell on bare ground.
