context_page_description: The Philippine Area of Responsibility is an area in the Northwestern Pacific where PAGASA, the Philippines' national meteorological agency monitors weather occurrences. Significant weather disturbances, specifically tropical cyclones, that enter or develop in the PAR are given Philippine-specific names.
context_section_description: Aside from the PAR, PAGASA forecasters have two other areas of responsibilities for tropical cyclone monitoring: the Tropical Cyclone Advisory Domain (TCAD) and the Tropical Cyclone Information Domain (TCID). Together with the PAR, these three areas of the Northwest Pacific Basin are collectively called domains. Since most tropical cyclones come from the broad expanse of ocean east of the country, the eastern boundaries of the PAR, TCAD and TCID are farther from the archipelago than the western boundaries.
  The TCAD, considered to be the "middle domain," is located between the PAR and the TCID. TCAD tropical cyclones are too far to have any direct effect to the country but are close enough for monitoring by the PAGASA and prompts the agency to issue a Tropical Cyclone Advisory (a less serious form of tropical cyclone bulletin than the SWB). The TCAD includes the area bounded by the imaginary lines connecting the coordinates: 4°N 114°E, 28°N 114°E, 28°N 145°E, 4°N 145°E. Note that though the TCAD completely encloses the PAR, it does not include the area within the PAR.
  On the other hand, the TCID is the largest and the outermost domain of PAGASA. TCID tropical cyclones are of least concern for PAGASA but are still necessary enough for monitoring and public awareness. The TCID is the area enclosed by the imaginary lines connecting the coordinates: 0°N 110°E, 35°N 110°E, 35°N 155°E, 0°N 155°E. Similarly, the TCID excludes the area enclosed by the PAR and the TCAD.
