The 1945 Pacific typhoon season was the first official season to be included in the West Pacific typhoon database. It has no official bounds; it ran year-round in 1945, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.

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 1945 Pacific hurricane season. Tropical Storms formed in the entire west pacific basin were assigned a name by the Joint Typhoon Warning Center. Tropical depressions in this basin have the "W" suffix added to their number. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two names.

Tropical Storm Ann

Tropical storm (SSHWS)
DurationApril 19 – April 26
Peak intensity95 km/h (60 mph) (1-min)  995 hPa (mbar)

Tropical Storm Ann was the first storm of the 1945 Pacific typhoon season and was formed on April 19. The storm made no landfall. It dissipated on April 26.

Tropical Storm Betty

Tropical storm (SSHWS)
DurationMay 13 – May 16
Peak intensity100 km/h (65 mph) (1-min)  994 hPa (mbar)

Tropical Storm Betty formed on May 13, 1945, and began to move in a northeastern direction. It strengthened into a tropical storm only 18 hours later, and continued on its path. However, the storm eventually moved further north, and into colder waters. Betty weakened into a tropical depression and dissipated on May 16th, having not threatened land at all.

Typhoon Connie

Category 1 typhoon (SSHWS)
DurationJune 1 – June 7
Peak intensity130 km/h (80 mph) (1-min)  980 hPa (mbar)

A small, yet powerful typhoon, Connie, was first spotted on June 1 by the Weather Central Guam, moving northeast. Winds were reported to have been as high as 140 mph. But by June 7, it began to weaken. Its final fate is unknown. The U.S. Navy's Third Fleet was hit by Connie. The same fleet had previously been hit, with great loss of life, by Typhoon Cobra, in 1944. Connie being lesser, only one officer and five USN men were lost or killed because of Connie, and around 150 airplanes on its carriers were either lost or damaged.

In Japan, Typhoon Ida is called Makurazaki Typhoon. It was the strongest typhoon to hit Kyushu on record, with a minimum sea-level pressure of 916.1 hPa (27.05 inHg) and a maximum wind gust of 62.7 metres per second (140 mph), which was recorded at a weather station in Makurazaki.[2] More than 2,000 people were killed in the Hiroshima Prefecture after heavy rains brought by a weakening Ida caused severe landslides.[3]

Louise was first seen developing on October 2, 1945, in the Caroline Islands. It unexpectedly veered north and slowed down, only to intensify as it passed over Okinawa on October 9 with 90 mph wind gusts and a minimum central pressure of 968.5 mbar. Shortly after, Louise began to weaken, and hit Japan as a strong tropical storm. The tropical cyclone became extratropical shortly after on October 12. In Okinawa, 36 people died, 47 people were reported missing, and 100 people were seriously injured.

In Buckner Bay, where the US military were occupying a temporary base, 30 ft (9.1 m) to 35 ft (11 m) waves were reported to have crashed ashore, tearing into Quonset huts and other buildings. At the time, Buckner Bay was being used as a port by the US military. Fifteen merchant ships were driven ashore, with a few wrecked. Three US Navy destroyers were grounded and declared beyond salvage. Over 200 other US military vessels, including six LSTs, a number of special purpose boats, patrol boats, and amphibious landing craft were grounded, severely damaged, or wrecked beyond repair. Eighty percent of the buildings in the bay were completely wiped out, while all 60 airplanes at the local airports were damaged.[4]
