Hurricane Patsy (was also Typhoon Patsy, international designation: 5912) was a tropical cyclone of both the 1959 Pacific typhoon season and the 1959 Pacific hurricane season. Moving erratically near the international dateline, the tropical cyclone never made landfall; it came close to Midway as a Category 3 hurricane, but caused no known impact, perhaps due to its small size. It is notable for being the earliest known Category 5 hurricane, and the hurricane was an uncommon west-to-east International dateline crosser.
