1989 WMHB Pacific hurricane season (Cooper)

The 1989 Pacific hurricane season was a very active season, although most of the storms were relatively weak and short-lived. 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.

Storm names
The following list of names was used for named storms that formed in the Northeastern Pacific in 1989. The names not retired from this list were used again in the 1995 season. This was the same list used in the 1983 season. Although it was not retired, the name Dalilia was later changed to Dalila for unknown reasons.

Retirement
In the spring of 1990, at the 12th session of the RA IV hurricane committee, the World Meteorological Organization retired the name Ismael from its rotating name lists due to the deaths and damage it caused, and it will not be used again for another Pacific hurricane. Ismael was replaced with Israel for the 1995 season.
