  5. Day 1·Oct 17·Watching·57cmFirst prediction

    Confidence grows: 57.2cm for Galdhopiggen Oct 24–28

    The prediction for the late-October North Atlantic system indicates a total of 57.2cm for Galdhopiggen over the window from October 24 to October 28, with a range of 16.5–128.6cm. Current data suggests a strengthening trend, which could lead to significant snowfall during this period. Galdhopiggen is likely to see the most snow, particularly on October 27, when we anticipate the biggest day with 20.6cm. Other resorts may not experience the same levels of accumulation, as the focus appears to be on Galdhopiggen. Should the models shift or show a different pattern, we could reassess the totals.
