2017 WMHB Pacific hurricane season (Cooper)

The 2017 Pacific hurricane season was an active Pacific hurricane season, with 18 named storms, 9 hurricanes, and 4 major hurricanes forming. The season officially started on May 15 in the eastern Pacific, and on June 1 in the central Pacific, while both ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Pacific basin. However, the formation of tropical cyclones is possible at any time of the year, as shown by the formation of Hurricane Adrian on May 9, becoming the earliest named storm to form in the eastern Pacific on record.
