The 2020 Pacific hurricane season is the ongoing annual season of tropical cyclones forming in the northern Pacific Ocean east of the date line . With the emergence of the first system on April 25th, the 2020 season will have the earliest start of a Pacific hurricane season since reliable records began in this area in 1966: "Eins-E" formed around two weeks earlier than the previous record holder " Adrian " in 2017.

The season officially begins on May 15 in the Eastern Pacific and June 1 in the Central Pacific. It ends on November 30th. These dates, by convention, represent the time of year when most tropical cyclones form; In principle, a tropical storm can form at any time.

On April 23, the National Hurricane Center (NHC) issued a Special Tropical Weather Outlook (STWO) because there was an extensive low pressure area a few hundred kilometers south of the tip of Baja California that showed the potential for tropical cyclogenesis . As a result, this trough developed rapidly and convection formed around the elongated center. The low was enlarged by an extraordinary outflow on the north side and developed slowly during the day and night of April 24th as it broke away from the intertropical convergence zone . Therefore, the NHC assessed the possibility of a tropical system developing within 48 hours as high. Although the thunderstorms began to fade near the center, the center took on a more rounded shape. On April 25, an ASCAT scan indicated that the low pressure area formed a better defined center during the night and that the circulation was completely covered by new thunderstorm activity. At about this time, around 15:00 UTC on April 25, the NHC declared the system to be Tropical Depression One-E. It is thus the earliest formation of a tropical low pressure system in the eastern North Pacific (east of 140 ° west longitude), since 1966 reliable observations began. Previously, the earliest formation was that of Tropical Storm Adrian of the 2017 Pacific Hurricane season , which formed on May 9th. A small convective cell allowed the low pressure area to maintain its intensity, even though dry air entered the circulation. On April 26, dry air, increasing wind shear and a cooler water surface began to affect the small cyclones, so that the deep convection in the center quickly dissolved, leaving a free, poorly defined center with little thunderstorm activity that just met the criteria for a tropical system . A few hours later the system was declared dissolved.

Storm names

The following list of names will be used for naming in the Northeast Pacific in 2020. If the World Meteorological Organization does not announce any name deletions in spring 2021, this list will be used again in 2026. The list is the same as the one used in the 2014 Pacific Hurricane season , with the exception of the name Odalys , which replaced Odile .
