Avalanche Activity

Moderate avalanche danger at higher altitudes

Older and small-sized freshly generated snowdrift accumulations are often still prone to triggering at high altitudes. Winter sports enthusiasts can trigger small, in isolated cases medium sized slab avalanches in wind-loaded zones, particularly on steep W-N-SE facing slopes and in gullies and bowls. At lower altitudes, wet snowslides and small avalanches will be possible.

Snowpack Structure

The fresh fallen snow and drifts from the most recent period of precipitation have settled further as a result of higher temperatures. Bonding to the often loosely-packed, faceted, expansively metamorphosed old snowpack surface, and inside the unfavorably structured layers of the old snow, continues to be moderate-to-poor in places. As a result of mild temperatures, the snow at low and intermediate altitudes is moistened and the snowpack surface is melt-freeze encrusted in early morning. At low altitudes there is little snow on the ground.

Weather Forecast

Slight foehn-wind impact. Sun will shine most of the time in the mountains, only in the Rätikon-Silvretta zone will dense cloudbanks move in from the south. Mild temperatures will prevail. At 2000m: +1 degree; at 3000m: -5 degrees. Moderate southerly winds at high altitudes and in foehn lanes, later intensifying to brisk.

Tendency

No significant change is anticipated.
