- Day 1·Oct 14·Watching·51cmFirst prediction
Watch issued: 0–85cm for Galdhopiggen, 2026-10-24 to 2026-10-27
THE PREDICTION: 0–85cm for Galdhopiggen between 2026-10-24 and 2026-10-27, 51cm our central figure. The biggest day is 2026-10-26 at 36cm. Galdhopiggen is the only resort clearing our threshold so far. We are watching a significant system for the Alps and wider Europe, 10 days out. Confidence is watching: the signal has crossed our threshold but the models still disagree on how much. 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.
