Snowdrift accumulations and glide-snow problem up to summit levels: caution

Snowdrift accumulations and glide-snow problem up to summit levels: caution

Fresher and older snowdrift accumulations are still easy to trigger. Danger zones occur on N/SE facing slopes, esp. near ridgelines and in gullies, bowls. Avalanches of medium size can be triggered in some places above 2000 m even by minimum additional loading (1 person). Danger zones increase with ascending altitude, are often blanketed with fresh snow and are difficult to recognize. Glide-snow activity persists. Medium-sized avalanches can trigger at any time on steep grassy slopes and over rock plates. Areas below glide cracks should be avoided.

The fresh snow is bonding well with the old snowpack. Due to light-to-moderate NW winds, small snowdrifts can accumulate anew, are most easily triggered where they are deposited atop loose snow. That means at high altitudes or on shady slopes. On sunny slopes and at low altitudes the snow has settled well in the interim Below 2400 m, the well bonded snowpack can glide down towards the valley on smooth ground.

On Wednesday, reduced visibility due to fog and clouds. Overall 5-10 cm of fresh snow can be expected. The W/NW winds will be moderate (up to 30 km/hr). At 2000 m: -7 degrees.

No significant change is expected.
