Melt-freeze, corn snow, slushy snow: marked daytime cycle
Avalanche danger is LOW (1) and rises to MODERATE (2) due to radiation warmth. In the morning, conditions are very favourable, subsequently followed by corn snow. As of midday, naturally triggered avalanche activity rises: wet-snow avalanches on steep sun-drenched slopes and glide-snow avalanches on steep grassy slopes below 2800 m. Foehn wind is braking the transformation to corn snow on the Main Tauern Ridge.
Danger of avalanches is LOW in the morning, then increases as a result of the strong spring sun to MODERATE. Due to loss of firmness, wet-snow avalanches (most small, some medium) are possible in extremely steep, sunny terrain.
After a night of clear skies and adequate outgoing radiation, the melt-freeze crust on sunny slopes is capable of bearing loads on Easter Monday. During the day the crust softens with varying swiftness depending on altitude, exposition and steepness of the slope. Stark opposites often prevail between sunny and shady slopes: on sunny slopes the snow becomes quite deep below 2200 m, intermediate altitudes are increasingly bare of snow altogether; on shady slopes the crust often remains hard above 2500 m. In wind-exposed terrain, particularly on the Main Tauern Ridge, foehn wind is slowing down the transformation to corn snow in the morning.
Alpine Weather Forecast (ZAMG Salzburg)
After a night of star-studded skies, lots of sunshine with some high altitude cloud on Monday. Light conditions will be somewhat diffuse near the Tauern, the peaks will remain free. Southerly winds will intensify, blowing at 30-50 km/hr in the Tauern. At 2000 m: +7 degrees; at 3000 m. 0 degrees.
Short Term Development
On Tuesday in Tauern and Nockberge, breakable crusts, not many reserves of cold remain and the rain will further weaken the snowpack, raise the danger of wet-snow avalanches. Further to the north, melt-freeze crusts capable of bearing loads; corn snow is possible, depending on the sun.
