Joint Typhoon Warning Center [SEP] History
The origins of the Joint Typhoon Warning Center can be traced back to June 1945, when the Fleet Weather Center/Typhoon Tracking Center was established on the island of Guam, after multiple typhoons, including Typhoon Cobra of December 1944 and Typhoon Connie in June 1945, had caused a significant loss of men and ships. At this time the centre was one of three Navy and two Air Force units responsible for tropical cyclone reconnaissance and warnings in the Pacific. Over the next few years the coordination of tropical warnings between the centres was at times difficult or impossible due to various communication problems.
