context_page_description: The 1997 Pacific hurricane season was the most active season since the 1994 season, producing 24 tropical depressions, 19 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 June 1 and the final storm crossed into the western Pacific on December 6, thus ending the season. There were 24 cyclones in both the eastern and central Pacific, including 5 unnamed tropical depressions.
