Danger of wet avalanches even in the morning.

Danger of wet avalanches even in the morning.

Avalanche danger below 2800m is considerable, above that altitude danger is moderate. Danger zones for wet-snow and glide-snow avalanches occur on very steep shady slopes below 2400m, on very steep sunny slopes below 2800m. Due to higher daytime temperatures and solar radiation, the danger of wet-snow and glide-snow avalanches will increase already during the morning hours. Wet-snow avalanches can trigger naturally in all aspects in high-altutude starting zones and grow to medium size. If they sweep along the thoroughly wet old snowpack they can in isolated starting zones where snow is sufficient grow to large size. In addition, the old snowpack can be triggered by large additional loading in extremely steep terrain. Danger zones occur in seldom-skied backcountry touring terrain, esp. on very steep NW/N/NE-facing slopes and are difficult to recognize. Backcountry tours require a cautious route selection.

On E/S/W-facing slopes up to high-alpine regions and on shady slopes up to 2400m, the moist snowpack is able to consolidate somewhat during the nighttime hours, then softens during the morning. On south-facing slopes there is hardly any snow on the ground up to high altitudes. Also on shady slopes, intermediate altitudes are becoming bare of snow. On very steep shady slopes at high altitudes, unfavorable intermediate layers are evident inside the old snowpack.

On Wednesday it will be quite sunny, though with some clouds. Towards evening, local rain showes are possible. At 2000m: 5-10 degrees. Brisk to strong-velocity southerly winds, blowing at storm strength in gusts in the foehn lanes.

Wet-snow and gliding snow remain the major danger.
