The season had no official bounds, but tropical cyclones in the Western Pacific Ocean normally develop between May and October.

The scope of this article is limited to the Pacific Ocean, north of the equator and west of the International Date Line.

Tropical Storms formed in the entire west pacific basin were assigned a name by the Fleet Weather Center on Guam.

At noon on December 31, a vortex was noted along the Intertropical Convergence Zone about 1,300 miles (2,100 km) south of Hawaii.

On January 7, the relatively small tropical storm struck Jaluit Atoll within the southern Marshall Islands, killing 14 people.

Ponape was struck on January 10, where Ophelia tore off the roof of the United States Weather Bureau office.

Ophelia severely impacted Yap, removing the Weather Bureau office's sheet metal roof and damaging the inflation building, theodolite, and radio antenna.

Typhoon Ophelia caused widespread damage on several islands of the Western Pacific.

[2] Ophelia also killed nine people when a USAF WB-50 crashed during a recon flight into the storm on January 15.

The storm moved generally west-northwestward and northwestward, reaching the Ryukyu Islands before dissipating on July 6.

Tropical Storm Alice developed on July 14 in the open western Pacific Ocean.

[5] Shortly after Typhoon Alice made landfall, storm surges occurred in Tokyo Bay,[7] causing floods in Kōtō and Edogawa on Shitamachi region.

[8][9][10] In the area of Kameido (now a station), storm surge in Tokyo Bay reached 2.89 meters in height.

Flossie peaked at 105 miles per hour (169 km/h) on the 22nd, and weakened to a 70-mile-per-hour (110 km/h) tropical storm just before hitting the southeastern coast of Japan on the 25th.

On the 22nd Ida turned to the north and quickly intensified, reaching super typhoon status on the 23rd and peak winds of 200 miles per hour (320 km/h) on the 24th.

Such winds are speculative, due to the lack of satellite or quality in measurements, but Ida was likely a formidable typhoon with a record low pressure (at the time) of 877 mbar.

[12] Ida weakened as it continued to the north-northeast, and made landfall on southeastern Honshū with winds of 80 miles per hour (130 km/h) on the 26th.

The system strengthened into a super typhoon, peaking with a minimum barometric pressure of 920 mbar (27 inHg).
