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. The heaviest known rainfall from a tropical cyclone on the state of Hawaii occurred with Hiki, when over 52 inches/1320 mm fell at Kanalohuluhulu Ranger Station.[1] Moderate damage was seen on Hawaii, and one person died.

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 (210 km/h) winds. It turned to the northeast, and became extratropical on the 17th.

On October 1, a hurricane was seen in the Eastern Pacific. It moved northeastward, hitting Baja California and Mexico before dissipating over New Mexico on the 6th.

Another hurricane moved up the western Mexican coast before hitting and dissipating on the 21st.

Main article: Hurricane Nina (1957)

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.

On June 14, a tropical storm hit southern Mexico.

A tropical storm developed rapidly just east of Hawaii on August 7. It moved westward into Hilo, where its circulation was greatly disrupted. A weakened depression persisted for 2 more days before dissipating. While weak, the storm caused very heavy flooding resulting in $500,000 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.

Gwen is not present in the best track file, but it is not known if it had been found not to have been a tropical cyclone, or if it was reduced to a depression.

The remnants of Tropical Storm Eleanor caused 2 inches (51 mm) of rain over Hawaii on July 22.

A tropical vortex out of the Intertropical Convergence Zone brought 3 more inches of rain to the rain-flogged state of Hawaii in mid-August.

Hurricane Katrina moved up Baja California and dissipated over Arizona on September 3. The remnants brought 2 inches of rain to the southwest of the United States. In Mexico, Katrina caused significant damage to parts of San Felipe. A total of 2500 people were left homeless and 60 ships were sunk. At least one person was killed.[3]
