1950-1969 Pacific hurricane seasons
From Wikipedia, the free encyclopedia
The 1950-1969 Pacific hurricane seasons all began on May 15, 1950-69 in the northeast Pacific Ocean and on June 1, 1950-69 in the central Pacific. They ended on November 30, 1950-69. These dates conventionally delimit the time of year when most tropical cyclones form in northeast Pacific Ocean.
Before the satellite age started in the 1960s, data on east Pacific hurricanes is extremely unreliable. Most east Pacific storms are of no threat to land. Only ones that made landfall or are notable in some way are mentioned.
[edit] 1950 Season
Seven tropical systems were observed this season.
A tropical depression formed over the Central Pacific on August 12, southeast of Hawaii. It tracked west-northwestward, strengthening to become Tropical Storm Hiki the next day (Hawaiian for Able). Hiki reached hurricane strength while a short distance north of the islands. A small hurricane, it paralleled the islands until the 17th, when a high pressure system forced the storm southwestward. As the high receded, Hiki moved to the northwest and dissipated on the 21st. Moderate damage was seen on Hawaii, and one person died.
[edit] 1951 Season
Nine tropical systems were observed this season.
A tropical storm and a hurricane hit near Acapulco, Mexico early in the season in May and June, respectively.

A tropical storm strengthened to a hurricane north of Hawaii in early August, one of only a few hurricanes to do so in the Eastern Pacific.
A disturbance in the Intertropical Convergence Zone developed into a tropical storm on September 1. Della moved west-northwestward, strengthening to a hurricane while west of Hawaii. There, it brought heavy surf to the western islands. The hurricane continued generally westward, moving to the southwest while crossing the International Date Line. Della turned to the northwest, where she reached her peak of 130 mph winds. It turned to the northeast, and became extratropical on the 17th.

A very late season tropical storm developed from the Intertropical Convergence Zone south of Hawaii on November 29. The storm, named Nina, moved northeastward, reaching hurricane strength on the 30th. Nina turned westward, but a high pressure system to its northwest forced it southward where it dissipated on December 6. High waves resulted in $100,000 in damage.

[edit] 1960-1966 storm names
These two lists were used sequentially. When the bottom of one list was reached, the next name was from the top of the other. List 1 is the same list used in the 1968 Season. List 2 is the same list used in the 1969 season. When the second list was exhausted in 1965, that same list was restarted instead of returning to the first list.

Storms named Madeline in 1961, Hazel in 1963, and Sylvia in 1964 were found to have been tropical depressions and shouldn't have been named. The name Gwen was used for a system in 1960. Gwen is not present in the best track file, but it is not known if it was found not to been a tropical cyclone, or if it was reduced to a depression.
