  3. Day 5·Oct 31·Watching·57cm(+4)

    Forecast: 57cm for Kirkwood, 25.6–90.8cm window Nov 3–11

    Day 5: totals up 12cm since the previous entry and the window held.

    Window Nov 3–11 · Kirkwood

  4. Day 4·Oct 30·Watching·53cmFirst prediction

    Forecast: 53cm for Mt. Washington, 0–123.4cm window Nov 5–9

    The prediction for the early-November Pacific system indicates a total of 53cm for Mt. Washington, with a range of 0–123.4cm. Current patterns suggest a favorable setup for snowfall across parts of North America, but confidence levels vary. Mt. Washington stands to benefit the most, while Alyeska Resort and Shames Mountain may see less accumulation, with trends weakening for both. Alyeska is projected to receive 39cm, and Shames Mountain 38cm, but these totals could shift as the event approaches. A change in the storm's trajectory or intensity could significantly alter these forecasts.

Above the summit line it rains on the whole mountain; below the base line it snows all the way down. Blue bars are snow in cm, amber bars rain in mm; the totals above are their sums.
