Fresh snow and snowdrifts prone to triggering at high altitudes

Fresh snow and snowdrifts prone to triggering at high altitudes

Fresh snowdrift accumulations at high altitudes can trigger small-to-medium sized slab avalanches by large additional loading. Danger zones occur esp. in steep ridgeline terrain in W/N/E aspects and in wind-loaded gullies and bowls. As daytime temperatures rise and solar radiation intensifies, small loose-snow avalanches are possible on very steep sunny slopes. On steep smooth grassy slopes, small glide-snow avalanches are possible.

The fresh snow which has fallen since Monday has been able to settle and bond with the compact old snowpack surface. At high altitudes the recent bout of fresh snow and drifts is still prone to triggering in places. Solar radiation and daytime warming on sunny slopes has caused the snowpack to forfeit its firmness. At low altitudes there is only little snow on the ground.

Nocturnal hours: heavy cloud, intermittent minor snow showers. In the morning, clouds will disperse. Thursday: extensive cloudbanks will hamper the sunshine intermittently. All in all, conditions will be pleasant, visibility adequate but diffuse. At 2000 m: rising from -4 to +2 degreers. Moderate W/NW winds.

Friday will be very sunny and warm: at 2000 m: from +6 to +9 degrees. At high altitudes and in foehn lanes, strong southerly winds will be noticeably. Danger of dry-snow avalanches will gradually recede. Danger of wet-snow avalanches will increase again.
