The Japanese Meteorological Agency did not track Colleen as a tropical storm. Tropical Depression 32W/33W (Sendang) Tropical Depressions 32W and 33W, though operationally treated as two separate cyclones, were in actuality one system; a relative rare event that shows the difficulties of tracking poorly organized storms. 32 developed on November 30 east of the Philippines. Operationally it was said to have tracked to the northeast and dissipated, with a second area of convection to the west becoming 33W. 32's convection became disorganized with the shower activity heading northeastward, but the low level circulation remained behind and headed westward to be called 33. The depression headed west-southwest, where it brought heavy rain to the Philippines on the 4th and 5th, killing 14 people. The most recent example prior to this system that had two names was Tropical Storm Ken-Lola in the 1989 Pacific typhoon season. Tropical Depression 34W 34W stayed at sea. Severe Tropical Storm Dan (Trining) Dan did not affect land. Storm names During the season 24 named tropical cyclones developed in the Western Pacific and were named by the Joint Typhoon Warning Center, when it was determined that they had become tropical storms. These names were contributed to a revised list from mid-1989. However this is the last season using this naming list since the JTWC revised a new naming list in 1996. Philippines The Philippine Atmospheric, Geophysical and Astronomical Services Administration uses its own naming scheme for tropical cyclones in their area of responsibility. PAGASA assigns names to tropical depressions that form within their area of responsibility and any tropical cyclone that might move into their area of responsibility. Should the list of names for a given year prove to be insufficient, names are taken from an auxiliary list, the first 10 of which are published each year before the season starts. Names not retired from this list will be used again in the 1999 season. This is the same list used for the 1991 season. PAGASA uses its own naming scheme that starts in the Filipino alphabet, with names of Filipino female names ending with "ng" (A, B, K, D, etc.). Names that were not assigned/going to use are marked in . Retirement Due to an extreme death toll caused by Typhoon Rosing in the Philippines, PAGASA later retired the name Rosing and was replaced by Rening for the 1999 season.
