 During a storm on January 24–25, 1956, a rain gauge at Kauai's former Kilauea Sugar Plantation recorded a record of precipitation in just 60 minutes.The value for one hour is an underestimate, since the rain gauge overflowed, which may have resulted in an error by as much as an inch.An accurate measurement may have exceeded Holt, Missouri's world-record rainfall of 12 inches in 42 minutes on June 22, 1947.
