The Philippine Area of Responsibility (PAR) is an area in the Northwestern Pacific where PAGASA, the Philippines' national meteorological agency monitors weather occurrences. Significant weather disturbances, specifically, tropical depressions and tropical cyclones, that enter or develop in the PAR are given Philippine-specific names.


Philippine Area of Responsibility

The area is bounded by six points namely:[1]

This area encompasses almost all of the land territory of the Philippines, except for the southernmost portions of the province of Tawi-Tawi, and some of the country's claimed islands in the Spratlys. The area also includes the main island of Palau, most of Taiwan, as well as portions of the Malaysian state of Sabah and the Japanese prefecture of Okinawa.


The establishing decree of PAGASA mandates the weather agency, particularly its National Weather Office, to monitor weather occurrences occurring within the PAR. This area is defined by the World Meteorological Organization.[2][3]

Tropical depressions and tropical cyclones (typhoons) are only assigned local names by PAGASA when they enter or develop within the PAR.[4][5] These names are provided in parallel with internationally recognized names designated by the Japan Meteorological Agency. The rationale for providing local names is that it is felt that Filipinos will respond more to familiar names and that it helps to underscore that these named weather disturbances pose a direct threat to the country. Furthermore, PAGASA provide names when a low pressure area becomes a tropical depression, in contrast to international names that are only provided for tropical cyclones, due to the fact that tropical depressions can still cause flooding and other damage.[6]

When a named weather disturbance within the PAR has made or is expected to make a landfall in the Philippines, PAGASA is mandated to issue weather bulletins every six hours. If the weather disturbance is not affecting land, the weather agency has to issue bulletins every 12 hours.[7]
