Timeline of the 1990 Pacific hurricane season

The Central Pacific hurricane season began on June 1, covering tropical cyclone formation in the region between 140°W and International Dateline.

[2] The season produced twenty-seven tropical depressions, of which twenty-one became named storms, and sixteen strengthened into hurricanes.

[nb 1] Despite high levels of activity, Rachel was the only system to make landfall, bringing floods to Northwestern Mexico and the Southwestern United States.

[1] One tropical storm formed in the Central Pacific Hurricane Center's warning zone and eventually crossed the International Dateline before dissipating.

This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, and dissipations during the season.
