Day 6: totals down 4cm at Galdhopiggen, the window slid 1 day later, 1 dropped out. Current prediction: 14–148cm for Galdhopiggen between 2026-10-25 and 2026-10-29, 73cm our central figure. The biggest day is 2026-10-25 at 29cm. Also in the path: Engelberg-Titlis 43cm. Confidence is likely: the models agree on both the window and the magnitude. On day one we said 76cm from 2026-10-24; that is the number we are measured against. What to watch next: whether the models hold the window, whether the low tracks closer to the core resorts, and the freezing level in the days before it arrives. 3 days to go.

Watch issued: 27–127cm for Galdhopiggen, 2026-10-24 to 2026-10-29
THE PREDICTION: 27–127cm for Galdhopiggen between 2026-10-24 and 2026-10-29, 76cm our central figure. The biggest day is 2026-10-25 at 31cm. Also in the path: Engelberg-Titlis 62cm, Kitzsteinhorn - Kaprun 37cm. We are watching a significant system for the Alps and wider Europe, 3 days out. Confidence is likely: the models agree on both the window and the magnitude. Resorts nearest the core of the moisture win; totals fall off away from it, and the lowest bases are the first to see rain mixed in. The prediction changes if model agreement loosens, the window slides later, or the freezing level trends higher. We will update this log every scan until the window opens.
