Avalanche Activity

Generally favorable conditions, low-to-moderate avalanche danger

Small-area avalanche prone locations in the form of fresh and older snowdrift accumulations, esp. in wind-loaded steep terrain, in gullies and bowls, and behind protruberances in the landscape. These tend to increase with ascending altitude. In addition, on steep shady slopes at high altitudes where the snow is shallow and in transitions from shallow to deep snow, slab avalanches can be triggered. A cautious route selection is imperative. At lower altitudes, isolated small avalanches are possibly triggered in extremely steep terrain. Naturally triggered small loose-snow avalanches are possible on extremely steep sunny slopes.

Snowpack Structure

Amid mild temperatures, the snowpack is settling and stabilizing to an increasing extent. The uppermost snowpack layers are generally still loose (except in wind-impacted terrain). In high-altitude wind-impacted zones and ridgelines, small fresh snowdrift accumulations have been generated. Some older drifts are now blanketed and layers of graupel embedded. More deeply embedded layers inside the snowpack are unlikely to trigger, at most where the snow is shallow and on very steep shady slopes.

Weather Forecast

A high-pressure front is st bringing stable weather conditions with outstanding visibility. Relative mild for this juncture of the season, the zero-degree level will ascend to nearly 3000m. At 2000m: +5 degrees. Moderate to brisk southeasterly winds at high altitudes, foehn impact from Rätikon to Hochtannenberg.

Tendency

Favorable avalanche situation will continue for the most part
