Fresh wind slabs are to be evaluated critically. Gliding avalanches are still possible.
As a consequence of new snow and a sometimes strong northwesterly wind, easily released wind slabs will form. Caution is to be exercised in particular on steep shady slopes in areas close to the tree line and above the tree line. Places where surface hoar has been covered with snow are especially unfavourable. The avalanche prone locations are clearly recognisable to the trained eye. Isolated small and medium-sized gliding avalanches are possible on steep grassy slopes. Areas with glide cracks are to be avoided. Avalanches can additionally in very isolated cases be released in the weakly bonded old snow. These avalanche prone locations are to be found especially on very steep shady slopes above approximately 2400 m, caution is to be exercised in particular at transitions from a shallow to a deep snowpack. Avalanches can reach medium size.
15 to 25 cm of snow has fallen. The wind will be moderate. Shady slopes: The snowpack consists of faceted crystals and has a loosely bonded surface. Steep sunny slopes: The snowpack consists of faceted crystals and its surface has a melt-freeze crust that is strong in many cases.
Fresh wind slabs are to be evaluated critically.
