**Mount Washington Observatory data show September peak gusts average around 94 mph historically, with a long-term record of 174 mph tied to Hurricane David remnants in 1979 and more typical recent values near 85–93 mph.** As the summit transitions from summer’s lighter winds (July–August medians often below 50 mph) into stronger autumn pressure gradients, the primary drivers of extreme gusts remain late-season tropical systems or their extratropical remnants that can track near the Northeast. With the Atlantic hurricane season peaking in September, National Hurricane Center track and intensity forecasts will be the dominant near-term catalyst. Continuous anemometer readings from the staffed observatory provide the official resolution data, and any early-month storm systems could quickly shift implied probabilities across multi-outcome thresholds.
