Timeline of the 1997 Pacific hurricane season

From Wikipedia, the free encyclopedia
Track map of the storms during the season

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. Of these, 19 were in the east Pacific; 8 peaked at tropical storm intensity, while 10 reached hurricane status. Seven of these reached Category 3 intensity or higher on the Saffir–Simpson Hurricane Scale, including central Pacific cyclones Super Typhoons Oliwa and Paka, which became typhoons after crossing into the Western Pacific.

Activity in the Central Pacific was above average; two tropical storms formed in addition to several tropical depressions. Some of the storms entered the region from the east. The 1997 season was the fourth-most active in the Central Pacific since satellite observations began. Nine tropical cyclones entered or formed in the region during that period.[1]
