2021 Pacific hurricane season (Cooper's Version)

The 2021 Pacific hurricane season was the first in a consecutive series of three very active Pacific hurricane seasons, producing 21 named storms, 12 hurricanes, and 7 major hurricanes. The season officially began on May 15, 2021 in the eastern Pacific, and on June 1, 2021 in the central Pacific, while the season ended in both basins on November 30, 2021. These dates historically describe the period each year when most tropical cyclones form in the Pacific basin and are adopted by convention.

Storm names
The following list of names was used for named storms that formed in the Northeastern Pacific in 2021. The names not retired from this list were used again in the 2027 season. This was the same list used in the 2015 season, with the exception of the name Pamela, which replaced Patricia, and was used for the first time this year.

For storms that form in the Central Pacific Hurricane Center's area of responsibility, encompassing the area between 140 degrees west and the International Date Line, all names are used in a series of four rotating lists. The next four names that were slated for use in 2021 are listed below.

Retirement
On April 25, 2022, at the 44th session of the RA IV hurricane committee, the World Meteorological Organization retired the name Marty from its rotating name lists due to the amount of damage and deaths it caused, and it will not be used again for another Pacific hurricane. Marty was replaced with Morton for the 2027 season.
