This report is published annually and summarizes Western North Pacific Tropical Cyclones. Annex A summarizes Tropical Cyclones from 180 degrees eastward to the North American Coast.

When directed by CINCPAC in May 1959, CINCPACFLT redesignated Fleet Weather Central Guam as Fleet Weather Central/Joint Typhoon Warning Center (FWC/JTWC) Guam with the following responsibilities:

1. To provide warnings to U. S. Government agencies for all tropical cyclones north of the equator and west of 180 degrees longitude to the coast of Asia and Malay Peninsula.

2. To determine tropical cyclone reconnaissance requirements and assign priorities.

3. To conduct investigative and post-analysis programs including preparation of the Annual Typhoon Report.

4. To conduct tropical cyclone forecasting and detection research as practicable.

Air Force Asian Weather Central at Fuchu, coordinating with U. S. Navy Fleet Weather Facility Yokosuka was designated as alternate JTWC in case of failure of FWC/JTWC Guam.

The JTWC is an integral section of FWC/JTiVC Guam and is authorized to be manned by three Air Force and three Navy officers and five enlisted men from each service. The senior Air Force Officer is designated as Director, JTWC.

The Western Pacific Tropical Cyclone Warning System consists of the Joint Typhoon Warning Center (JTWC), the U. S. Air Force 54th Weather Reconnaissance Squadron stationed at Andersen Air Force Base, Guam and U. S. Navy Airborne Early Warning Squadron One (VW-1) stationed at Naval Air Station, Agana, Guam.

The Joint Hurricane Warning Center in Hawaii, a coordinated agency composed of the U. S. Weather Bureau, Honolulu, the Air Force Central Pacific Forecast Center, and Fleet Weather Central Pearl Harbor, is responsible for tropical cyclone surveillance and issuance of warnings in the Central North Pacific area between 180 degrees and 140 degrees west.

U. S. Navy Fleet Weather Central, Alameda, California, is responsible for issuance of warnings from 140 degrees west longitude to the North American Coast.
