The 1958 Pacific typhoon season was an event in the annual cycle of tropical cyclone formation. The season had no official bounds, but tropical cyclones in the Western Pacific Ocean normally develop between May and October. The season was below average in storms, with only twenty-three forming. However, all but two of those storms developed into typhoons, resulting in a well above-average number of typhoons, and a very high ACE figure of 445.8 units. In addition, there were also nine tropical storms tracked only by the JMA. The season began very early, with a very rare super typhoon in January, Typhoon Ophelia, and ended in early December with Typhoon Olga. It also featured Typhoon Ida, the strongest storm ever recorded at that time.

The scope of this article is limited to the Pacific Ocean, north of the equator and west of the International Date Line. Storms that form east of the date line and north of the equator are called hurricanes; see 1958 Pacific hurricane season. Tropical Storms formed in the entire west pacific basin were assigned a name by the Fleet Weather Center on Guam.

Systems

Typhoon Ophelia

Typhoon (JMA)
Category 5 super typhoon (SSHWS)
Duration	January 6 – January 17
Peak intensity	260 km/h (160 mph) (1-min); 940 hPa (mbar)

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. It rapidly intensified, and reached winds of 140 miles per hour (230 km/h) the next day. Conditions became unfavorable, and steadily weakened to 105 miles per hour (169 km/h) winds. Ponape was struck on January 10, where Ophelia tore off the roof of the United States Weather Bureau office. On January 11, Truk was struck. The Weather Bureau's inflation shelter was destroyed, with other buildings on site severely damaged. On the 12th, favorable conditions allowed Ophelia to reintensify, reaching a peak of 160 miles per hour (260 km/h) on the 13th. Ophelia severely impacted Yap, removing the Weather Bureau office's sheet metal roof and damaging the inflation building, theodolite, and radio antenna. After maintaining that intensity for 18 hours, it quickly weakened as it drifted northward, and dissipated on the 17th. Typhoon Ophelia caused widespread damage on several islands of the Western Pacific. Ophelia also killed nine people when a USAF WB-50 crashed during a recon flight into the storm on January 15.

Peak intensity	325 km/h (200 mph) (1-min); 877 hPa (mbar)

On September 20, Tropical Storm Ida formed in the central Western Pacific. It moved to the west, rapidly strengthening to a 115-mile-per-hour (185 km/h) typhoon by the next day. 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. 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. It became extratropical the next day, and dissipated on the 28th to the east of the country. Ida caused torrential flooding to southeastern Japan, resulting in over 1,900 mudslides. Damage along the coastline was extensive, including two small villages that were washed away completely.
