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.http://www.usno.navy.mil/NOOC/nmfc-ph/RSS/jtwc/TCC/docs/JTWC_50th.ppt Joint Typhoon Warning Center 50th Anniversary May 1959 – May 2009 November 14, 2014 April 29, 2009 July 17, 2016 https://web.archive.org/web/20160717070350/http://www.usno.navy.mil/NOOC/nmfc-ph/RSS/jtwc/TCC/docs/JTWC_50th.ppt deadhttp://home1.gte.net/anstett/Jthist02.htm History of the Joint Typhoon Warning Center up to 1998 November 14, 2014 dead World War II Era https://web.archive.org/web/20120224205356/http://home1.gte.net/anstett/Jthist02.htm Anstett, Richard April 30, 1998 February 24, 2012 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.Landsea, Christopher W Dorst, Neal M June 1, 2014 Tropical Cyclone Frequently Asked Question Subject: Tropical Cyclone Names: B1) How are tropical cyclones named?

Systems Tropical Storm Ann WPac Ann 1945 track.png April 19 April 26 50 995 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 26.1945 Severe Tropical Storm ANN (1945110N09160) IBTrACS - International Best Track Archive for Climate Stewardship https://ncics.org/ibtracs/index.php?name=v04r00-1945110N09160 North Carolina Institute for Climate Studies May 16, 2023 Asheville, North Carolina Tropical Storm Betty WPac Tropical Storm Betty weather map, May 16, 1945.jpg Betty 1945 track.png May 13 May 16 55 994 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 WPac USS SHANGRI-LA - Rep of air opers against Kyushu, Japan & the Ryukyu Islands, 5-28-45-6-10-45 - DPLA - aa6fb89f128c233a548230309727a07f (page 18).jpg Connie 1945 track.png June 1 June 7 70 980 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 flip. But by June 7, it began to weaken. Its final fate is unknown. The United States Navy's Third Fleet was hit by Connie, which is also referred to as Typhoon Viper.https://www.usni.org/magazines/naval-history-magazine/2015/october/pittsburghs-typhoon-battle The Pittsburgh's Typhoon Battle Naval History United States Naval Institute 29 5 Barr Roger October 2015 11 July 2025 The same fleet had previously been hit, with great loss of life, by Cobra the previous year. Connie was not as powerful as Cobra, but the fleet was still damaged by the storm, with six men killed or lost overboard and four seriously hurt. The ships Hornet CV-12 6, Bennington CV-20 6, Windham Bay, Salamaua, Pittsburgh CA-72 6, Baltimore CA-68 6, and Duluth CL-87 6 suffered major damage and 26 vessels suffered minor damage. 76 planes were destroyed and 70 suffered damage. The damage sustained during Cobra and Connie led to improvements in design such as faster pumping arrangement for fuel and ballast tanks, better protection from the elements for electrical panels, and an effort to make ships less top heavy. They also sped up the development of storm forecasting and led to the development of hurricane hunters.Baldwin Hanson W. 1956 Sea Fights and Shipwrecks: True Tales of the Seven Seas Garden City, New York Hanover House 33 Tropical Storm Doris WPac Tropical Storm Doris analysis 19 Jun 1945.png Doris 1945 track.png June 18 June 21 45 997 Tropical Storm Doris existed from June 18 to 21 and did not make landfall.
