The 1991 Pacific hurricane season was an ongoing event in tropical cyclone meteorology, producing 16 tropical depressions, 14 of which became tropical storms or hurricanes. The season officially started on May 15, 1997 in the Eastern Pacific—designated as the area east of 140°W—and on June 1, 1997 in the Central Pacific, which is between the International Date Line and 140°W. The season officially ended in both basins on November 30, 1997. These dates typically limit the period of each year when most tropical cyclones form in the eastern Pacific basin. This timeline documents all the storm formations, strengthening, weakening, landfalls, extratropical transitions, as well as dissipation. The timeline also includes information which was not operationally released, meaning that information from post-storm reviews by the National Hurricane Center, such as information on a storm that was not operationally warned on, has been included.
The first storm formed on May 16 and the final storm dissipated on November 12, thus ending the season. There were 16 cyclones in both the eastern and central Pacific, including 2 unnamed tropical depressions. All of these formed in the eastern Pacific. Of this season's cyclones, 4 peaked at tropical storm intensity, while 10 reached hurricane status. Five of these reached Category 3 intensity or higher on the Saffir-Simpson hurricane scale, thereby becoming major hurricanes.
