List of off-season Pacific hurricanes : ウィキペディア英語版 | List of off-season Pacific hurricanes
There have been 20 recorded tropical and subtropical cyclones in the east Pacific basin outside the official Pacific hurricane season. The boundaries of the east Pacific stretch from North America westward to 140°W, while the central Pacific is from 140°W to the International date line, north of the equator. The National Oceanic and Atmospheric Administration (NOAA) currently defines the season as starting May 15 in the eastern Pacific and June 1 for the central Pacific and ending on November 30 for both regions in each calendar year.〔 Occasionally, however, storms develop in late November and persist until December, such as Hurricane Nina of 1957. Few off-season tropical cyclones in the east Pacific have affected land, and none of them have made landfall. Only Hurricane Nina caused both property damage and fatalities. The strongest hurricane between December and May was Hurricane Ekeka in 1992, which reached winds of . However, after Tropical Storm Paka crossed the International Date Line, it intensified into a typhoon with winds equivalent to a Category 5 hurricane on the Saffir-Simpson hurricane wind scale. The most recent off-season storm was Tropical Storm Aletta in May 2012. The beginning of HURDAT, the official east Pacific hurricane database, is 1949. Since then, ten storms have occurred〔〔 between January 1 and May 14, or December 1–31, outside the official bounds of hurricane season in the eastern and central north Pacific, respectively. In addition, the Central Pacific Hurricane Center reports seven off-season storms from 1900–1952 with another off-season tropical cyclone occurring in 1832. There have been documents published in the Monthly Weather Review reporting additional off-season storms within off the Mexican coastline, including one in December. ==Chronology==
The wind speeds listed are maximum one-minute average sustained winds. The category refers to the intensity on the Saffir–Simpson hurricane wind scale; TS stands for tropical storm, and TD for tropical depression.
