Fleet Weather Central/Joint Typhoon Warning Center (FWC/JTWC), Guam has the responsibility to:
1. Provide warnings to U.S. Government agencies for all tropical cyclones north of the equator and west of 180° longitude to the coast of Asia and the Malay Peninsula;
2. Provide warnings for the area from the Malay Peninsula west to 90°E;

Asian Tactical Forecast Center, Fuchu (formerly Air Force Asian Weather Central), coordinating with the Naval Weather Service Environmental Detachment, Yokosuka, is designated as the alternate JTWC in case of the incapacitation of FWC/JTWC Guam.
The JTWC is an integral part of FLEWEACEN Guam and is manned by four officers and five enlisted men each from the Navy and Air Force. The senior Air Force officer is designated as Director, JTWC.
The Western Pacific Tropical Cyclone Warning System consists of the Joint Typhoon Warning Center and the U.S. Air Force 54th Weather Reconnaissance Squadron stationed at Andersen Air Force Base, Guam.
The Central Pacific Hurricane Center, Honolulu, is responsible for the area from 180° eastward to 140”W and north of the equator. Warnings are issued in coordination with FLEWEACEN Pearl Harbor and the Air Force Central Pacific Forecast Center, Hickam Air Force Base, Hawaii.
The Eastern Pacific Hurricane Center, San Francisco, is responsible for the area east of 140”w and north of the equator. Warnings are issued in coordination with FLEWEAFAC Alameda and the Air Force Hurricane Liaison Officer, McClellan Air Force Base, California. FLEWEACEN Pearl Harbor replaced FLEWEAFAC Alameda in this coordinating role on 1 November 1972.
The coordinating agencies under CINCPACFLT and CINCPACAF are responsible for further dissemination and, if necessary, local modification of tropical cyclone warnings to U.S. military agencies.
