In late October, Hurricane Roslyn became the fourth major hurricane of the season and was the strongest landfalling Pacific hurricane since Hurricane Patricia in 2015. Also, Hurricane Julia became the second storm of the season to cross over from the Atlantic basin intact, and made landfall in El Salvador soon thereafter. In early October, Hurricane Orlene became a Category 4 hurricane before weakening and making landfall in Sinaloa as a Category 1 hurricane, resulting in heavy rainfall and flooding. Hurricane Kay also formed that month, and struck the Baja California Peninsula before bringing gale-force winds to the west coast of the continental United States, becoming the first Pacific hurricane to do so since Hurricane Nora 25 years earlier. In September, tropical storms Javier, Lester, and Madeline all caused flooding across the Pacific coast of Mexico, though none left severe damage. The season's first major hurricane, Hurricane Bonnie, entered into the basin from the Atlantic on July 2, after crossing Nicaragua as a tropical storm, becoming the first storm to survive the crossover from the Atlantic to the Pacific since Hurricane Otto in 2016. In June, Hurricane Blas and Tropical Storm Celia caused heavy rainfall over southwestern Mexico despite remaining offshore. The first named storm of the season, Hurricane Agatha, formed on May 28, and made landfall two days later at Category 2 strength on the Saffir–Simpson scale, making it the strongest hurricane on record to make landfall during the month of May in the Eastern Pacific basin. These dates historically describe the period each year when most tropical cyclogenesis occurs in these regions of the Pacific and are adopted by convention.
The season officially began on May 15 in the Eastern Pacific (east of 140°W), and on June 1 in the Central Pacific both ended on November 30. Also, it was the third consecutive season in which no tropical cyclones formed in the Central Pacific Ocean (from 140°W to the International Date Line, north of the equator). The 2022 Pacific hurricane season was a fairly active Pacific hurricane season, with nineteen named storms (including two that crossed over from the Atlantic), ten hurricanes, and four major hurricanes forming.
