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. 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. 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.

A small yet powerful typhoon, Connie was first spotted on June 1 by the Fleet Weather Center on 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, 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.
