Timeline of the 2016 Pacific hurricane season
The 2016 Pacific hurricane season was an event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the eastern Pacific Ocean. The season officially started on May 15 in the eastern Pacific–east of 140°W–and on June 1 in the central Pacific–between the International Date Line and 140°W–and ended on November 30. These dates typically cover the period of each year when most tropical cyclones form in the eastern Pacific basin. However the first storm, Pali, formed 5 months before the  official start of the season on January 7, which broke the record for having the earliest forming storm within the basin. During the season, 22 tropical depressions developed within the basin, 21 of which became tropical storms. 13 of the tropical storms reached hurricane strength, with six achieving major hurricane intensity. Additionally, Tropical Storm Otto entered the basin after crossing over from the Atlantic, thus further contributing to the season total. Four time zones are utilized in the basin: Central for storms east of 106°W, Mountain between 114.9°W and 106°W, Pacific between 140° W and 115°W, and Hawaii–Aleutian for storms between the International Date Line and 140°W. However, for convenience, all information is listed by Coordinated Universal Time (UTC) first with the respective local time included in parentheses. This timeline includes information that was not operationally released, meaning that data from post-storm reviews by the National Hurricane Center is included. This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, and dissipations during the season. Timeline of events. January.
