Lower Tauern South

Avalanche danger is MODERATE. Due to solar radiation and diffuse light, natural releases (loose dry and loose moist) are to be expected in extremely steep terrain (>40°). Small releases by 1 person are possible. Where snow is sufficient below 2600 m, small glide-snow avalanches can release naturally, esp. where recent snowfall fell on bare ground. Avoid zones below glide cracks. Fresh ridgeline snowdrifts can be triggered as a small slab even by 1 person. Danger zones occur on steep slopes (over 35°) on north facing slopes.

Loose snow on the surface can lose bonding through solar radiation, but radiation also helps the snowpack to settle. Weak layers in the uppermost part of the snowpack (blanketed fresh snow and graupel). In transitions from the old snowpack to the fresh snow there are graupl and facted layers above 2400 m, not easily triggerable. Reserves of cold are limited to shady slopes above 2600 m. Atop snowy steep rocks and grassy slopes the snowpack is wet at ground level and can glide away.

Nighttime skies will be clear. On Friday, initially good visibility and sunshine, but heavy cloud layers will move in during the morning from the southwest, making the light diffuse. Peaks should remain in the clear, foehn-generated bright intervals are possible. In the Northern Alps more pleasant. Winds light. At 2000 m: -2 degrees; at 3000 m: -9 degrees.

Due to higher temperatures the snowpack will moisten, the wet-snow problem will increase.
