The Jacksonville hurricane warning office moved to Miami, Florida in 1943, and a hurricane warning office was opened in Boston, Massachusetts. After World War II, the United States Navy and United States Air Force had separate warning centers for the military. In the case of tropical cyclones, the civilian and military warning agencies maintained close coordination. Tropical cyclone naming began for Atlantic tropical cyclones using the phonetic alphabet by 1947, switching to female names in 1953. Starting in 1950, the Miami Hurricane Warning Office began to prepare the annual hurricane season summary articles. Tropical cyclone track forecasts for one day in the future began in 1954. After the 1954 Atlantic hurricane season, efforts were made to enhance the hurricane reporting network along the coast by setting up a Cooperative Hurricane Reporting Network (CHURN) by supplying anemometers and barometers to members of the public which left no length of United States coastline along the Atlantic or Gulf coasts greater than uncovered.
