Danger Sign
• Recent avalanches • 2 Avalanches on the east facing slope at the lower end of Todalen. Size 1-2, spontaneous release.
Weather
• No precipitation • 3 m/s • Sunny, no clouds, 1 cm of snowfall in the last 24 h, stable air temp.
Tests
• ECTP3@7cm • Poor • Propagation not expected over longer distances.
Snow Profile
• 2 tests connected to snow profile • Persistent weak layer: thin layer, below slab, near surface
Avalanche Problems
• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • The weak layer collapses easily and clean (easy propagation). The collapsing weak layer is thin < 3 cm. • Easy to trigger • 1 - Small • Many steep slopes N, NE, E, SE, S, SW, W, NW • Slab too weak for extended Propagation, little avalanche activity expected
Avalanche Danger Assessment
• Weak layer present but too thick to collapse and the top layer to thin to cause extended fracture propagation. • The situation stabilizing from the previous week. • 1 Low • Forecast too high
Notes
• Group 1: Simon Grueter, Gabriele Bramati, Milot Malaj
