The 1945 Pacific typhoon season was the first official season to be included in the West Pacific typhoon database. It was also the first season to name storms. 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. Predecessor agency to the Joint Typhoon Warning Center (JTWC), Fleet Weather Center/Typhoon Tracking Center was established on the island of Guam in June 1945, after multiple typhoons, including Typhoon Cobra in the previous season and Typhoon Connie in this season, had caused a significant loss of men and ships.[1] [2] It would not take major responsibility in the West Pacific basin until 1950 season. Instead, storms in this season are identified and named by the United States Armed Services, and these names are taken from the list that USAS publicly adopted before this season had started earlier this year.[3] [4] Since this is the first season to be included in the West Pacific typhoon database, this would also be the first season where the names of Western Pacific tropical cyclones are preserved publicly.

| Track: | Ann 1945 track.png |
| Formed: | April 19 |
| Dissipated: | April 26 |
| 1-Min Winds: | 50 |
| Pressure: | 995 |
The first named storm of the season, Tropical Storm Ann formed on April 19 at relatively low latitude of 9.5°N. Ann generally tracked westward and later reached its peak intensity on April 21, before weakening to a tropical depression on April 23. The storm began to curve north the next day, and overall did not affect any landmasses and dissipated on April 26.[5]
Tropical Storm Betty

The second named storm of the season, 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 16, having not threatened land at all.
Typhoon Connie

The U.S. Navy's Third Fleet was hit by Connie, and reporting about the storm frequently refers to it as Typhoon Viper. The same fleet had previously been hit, with great loss of life, by Cobra the previous year. Connie being lesser, only one officer and five seamen were lost or killed because of Connie, though multiple ships were damaged, and around 150 airplanes on its carriers were either lost or damaged.

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, 30feet to 35feet 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.[10]
