Avalanche Activity

Low avalanche danger

Low avalanche danger prevails. A bit of solar radiation in the favored southern massifs, plus daytime warming, can create isolated sides in steep terrain.

Snowpack Structure

Due to recent weather developments (often mild, intermittent rainfall) the snowpack is either moist or wet. As temperatures drop the snowpack will regain some of its firmness, which will then be forfeited with rising daytime temperatures and brief windows of sunshine, causing isolated slides in isolated cases. There is no longer much snow on the ground.

Weather Synopsis

Cloud cover will move in from the north early on Easter Monday, then spread and become dense. In northern and eastern massifs, repeated bouts of snowpack in the morning (fluctuating snowfall level around 1000m). Temperature curve from NW to SW. At midday at 1500m: -2 degrees; at 2000 m: -6 degrees in NE, much lower than in SW regions where up to +4 degrees at 1500m and 0 degrees at 2000 m are expected.

Tendency

During the nocturnal hours the precipitation will spread throughout Styria. Also on Tuesday, dense intermediate altitude cloud can be expected all day long, plus snowfall, focal point in the northern barrier cloud regions. Snowfall level will fluctuate around 1000m (in NE regions lower, in SW regions higher). A moderate to strong NW wind will be blowing, shift to NE in the evening, then slacken off somewhat. Quite ample snowfall will bring wintery conditions back, accompanied by frequent (but easing) wind impact which will generate fresh snowdrift accumulations which require attentiveness. On Wednesday, weather conditions will improve and naturally triggered avalanches can be expected from the fresh snow on steep sunny slopes.
