Timeline of the 2020 Pacific hurricane season
The 2020 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 began on June 1 in the Central Pacific—the region 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 according to the National Hurricane Center. However , tropical cyclones sometimes form outside the bounds of an official season, as was evidenced by the formation of Tropical Depression One-E on April 25. The season ended with the dissipation of its final storm, Tropical Storm Polo, on November 19. The formation of One-E on April 25 marked the earliest start to a Pacific hurricane season on record. However, seasonal activity as a whole was generally below average. The season featured 16 named storms, in line with the 1981–2010 long-term average of 15. It featured just four hurricanes, or half the average. Three of those hurricanes intensified  into major hurricanes, which compares to the average of four. The accumulated cyclone energy (ACE) of the season, an index that measures the longevity and intensity of tropical cyclones, was more than 40 percent below the long-term average. A few storms produced substantial impact to land in 2020. In May, Tropical Storm Amanda caused widespread damage and killed numerous people in El Salvador, Guatemala, and Honduras. In August, the remnants of Tropical Storm Fausto sparked devastating wildfires across Northern California, while Genevieve produced hurricane-force winds and caused additional fatalities in the Baja California peninsula. Lesser but still deadly  effects were produced there by Tropical Storm Hernan as well. A month prior, Hurricane Douglas passed very close to Oahu, though it caused only minor impact. Timeline. 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 in Coordinated Universal Time (UTC) first with the respective local time included in parentheses. This timeline includes information  that was not released while the storm was active, meaning that data from post-storm reviews by the National Hurricane Center is included. This timeline documents the formation of tropical cyclones as well as the strengthening, weakening, landfalls, extratropical transitions, and dissipations during the season. April.
