2019 Pacific hurricane season (Harvey)


 * Phase 1: Alvin - Lorena
 * Phase 2: Mario - Alpha

The 2019 Pacific hurricane season was an extraordinarily active season that became the most active Pacific hurricane season ever, producing 29 named storms. Due to above-normal sea temperatures, low wind shear and a strong 2019-20 El Nino event, activity in both the Western and Eastern Pacific basins were record-breaking. This same El Nino influenced a very quiet Atlantic hurricane season.

The season officially started on May 15 in the eastern Pacific, and on June 1 in the central Pacific, and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean.

Hurricane Lorena
Lorena was a powerful, long lived storm that became the strongest storm of the season, as well as the second-most intense Pacific hurricane on record. It existed in all three Pacific basins, reaching category 5 status in all basins. Despite the extreme intensity, the name was not retired as it only caused minimal damage.

Its precursor did leave heavy rainfall in El Salvador, but caused minimal to no damage and no deaths.

Storm names
The following names will be used for named storms that form in the northeastern Pacific Ocean during 2019. All of the names were used this year, the names Wallis, York and Zelda were used for the first time this year, and Alpha was used in the eastern Pacific for the first time. This is the same list used in the 2013 season, with the exception of the name Mario, which replaced Manuel.

Retirement
On (date), at the 42nd session of the RA IV Hurricane Committee, the World Meteorological Organization retired the names Kiko, name and name due to the damage and deaths that they caused, and they will not be used again for another Pacific hurricane. They will be replaced with Replacement name for the 2025 Pacific hurricane season.
