The 1999 Pacific hurricane season was one of the least active Pacific hurricane seasons on record. The season officially began on May 15 in the Eastern Pacific, and on June 1 in the Central Pacific; in both basins, it ended on November 30. These dates conventionally delimit the period during which most tropical cyclones form in the northeastern Pacific Ocean. The first tropical cyclone of the season, Hurricane Adrian, developed on June 18, while the final storm of the season, Tropical Storm Irwin, dissipated on October 11. No storms developed in the Central Pacific during the season. However, two storms from the Eastern Pacific, Dora and Eugene, entered the basin, with the former entering as a hurricane.
The season produced fourteen tropical cyclones and nine named storms, which was well below the average of sixteen named storms per season; this was largely due to a strong La Niña taking over much of the Pacific. However, the total of six hurricanes and two major hurricanes during the season was near the averages of eight and three, respectively. Although it remained offshore, Hurricane Adrian caused 6 deaths from flooding and rough surf in Mexico. Hurricane Dora was a long-lived and intense cyclone, which had the second longest track of a Pacific hurricane on record. The storm brought minor impacts to the island of Hawaii; however, no deaths or damage was reported. The deadliest tropical cyclone, Hurricane Greg, killed 10 people from flooding in Mexico.
The 1999 Pacific hurricane season officially started on May 15, 1999 in the eastern Pacific, and on June 1, 1999, in the central Pacific, and lasted until November 30, 1999. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean. The 1999 Pacific hurricane season was well below average, due to the strong La Niña that was occurring at the time, which causes wind shear to be increased and water temperatures to decrease, resulting in conditions less conductive for tropical cyclones in the East Pacific. There were 14 cyclones in total, including 5 unnamed tropical depressions. Of these, 9 became a tropical storm, while 6 reached hurricane status. Further, 2 of these became major hurricanes, which is Category 3 intensity or higher on the Saffir-Simpson hurricane scale.
