within the northwestern pacific ocean, there are two separate agencies who assign names to tropical cyclones which often results in a cyclone having two names. the japan meteorological agency names tropical cyclones should they be judged to have 10-minute sustained windspeeds of 65 km/h, (40 mph), to the north of the equator between the 180° and 100°e. whilst the philippine atmospheric, geophysical and astronomical services administration assigns names to tropical cyclones which move into or form as a tropical depression in their area of responsibility between 135°e and 115°e and between 5°n-25°n even if the cyclone has had a name assigned to it by the japan meteorological agency.
