Hurricane Eugene, also known as Typhoon Eugene, was the longest lasting, and most intense, hurricane of the 2023 Eastern Pacific Hurricane Season. Eugene formed during the hyperactive 2023 Eastern Pacific Hurricane Season, and was the only storm in the season to reach Category 5 intensity on the Saffir-Simpson Hurricane Scale. Hurricane Eugene, during it's lifetime, was present in all three Pacific basins, the East, Central, and West Pacific. Because of Hurricane Eugene's movement into the Western Pacific basin, it was also designated as a typhoon, which is the West Pacific's name for tropical cyclones that are Category 1 and higher, making Eugene a quite unique tropical cyclone in that it has been designated as both a Hurricane and a Typhoon.
