Typhoon Judy Route Analysis
Track and Movement Characteristics
Typhoon Judy (196817) began its life over the open Northwest Pacific at 08:00 on October 21, 1968, at 9°N, 169°E. During its early formation, the system moved conspicuously westward, rapidly traveling from 169°E to near 154.9°E. Its latitude remained around 13.9°N from October 23 to 24, followed by a brief southward jog to 11.2°N on October 25, showing an initially unstable track. During its rapid development phase, the typhoon continued moving toward the west-northwest, crossing the eastern Mariana Islands.
The track turned significantly after October 30. Before then, the typhoon had moved steadily toward the west or northwest, but after reaching 17.9°N, 135.5°E on October 30, it gradually turned toward the northeast. From October 31 to November 2, its central longitude increased from 136.4°E to 139.7°E and its latitude rose to 22.1°N, indicating that the typhoon had completed a typical recurvature under the steering influence of the westerlies. It finally weakened and dissipated at 18.2°N, 140.7°E at 20:00 on November 4. It never made landfall and followed a typical remote-ocean recurving typhoon track.
Intensity evolution and historical comparison
Judy’s intensity evolved slowly, intensified explosively, and then declined rapidly. From October 21 to 24, the system remained a tropical depression, with pressure between 1004–1008 hPa. On October 25, it abruptly intensified into a typhoon with winds of 35 m/s, then reached super typhoon status within five days. It peaked on October 28–29, with maximum winds of 65 m/s and a minimum central pressure of 929 hPa, remaining a super typhoon for about 48 hours. After it began turning, its intensity dropped sharply. Winds fell to 50 m/s on October 30, and by November 2 it had weakened to a tropical storm. At the end of its life, pressure rose to 1008 hPa.
Compared with previous typhoons bearing the same name, Judy in 1968 reached a relatively high intensity. Its minimum central pressure of 929 hPa was lower than those of the Judys in 1989 (945 hPa), 1982 (956 hPa), and 1986 (970 hPa), indicating stronger core convection. However, its peak intensity remained slightly below the record minimum central pressure of 908 hPa set by Judy in 1979. Overall, although it caused no landfall-related damage, its rapid intensification over the open ocean placed it among the strongest storms in the Judy naming series.

Before then, JMA (Japan), the Joint Typhoon Warning Center (USA), and China's meteorological authorities each used their own numbering systems. Their numbers for the same typhoon may differ and cannot be directly compared.
Where does Typhoon Judy's track data come from?
