better defined, and Henriette reached its peak intensity of on September 7. The cyclone began weakening due to cold waters and its proximity to Gil. A Fujiwhara interaction between Henriette and Gil occurred on September 8. Henriette soon dissipated after losing its closed low-level circulation. Its remnants were absorbed by Gil. Tropical Storm Ivo Ivo formed from a large tropical wave that moved off the African coast on August 26. The wave was accompanied by a large cyclonic rotation at the low to middle levels and numerous thunderstorms when it entered the eastern Atlantic. On August 28, the wave spawned a northward-moving vortex in the eastern Atlantic, but the wave's southern portion continued westward with very limited convective activity. Once the wave reached the western Caribbean Sea on September 5, the shower activity increased and the whole system continued slowly westward over Central America. The cloud pattern gradually became better organized and by September 9, satellite images showed a low to middle-level circulation centered near Acapulco, Mexico. The next day, a portion of the system moved over water and it became a tropical depression about south-southwest of Acapulco on September 10. The center of the depression moved slowly west and west-northwestward with its circulation hugging the southwest coast of Mexico. There was moderate easterly shear over the depression as indicated by the location of the convection to the west of the center. Satellite images and a report from a ship indicated that the depression reached tropical storm status by 06:00 UTC September 11. Thereafter, there was only slight strengthening and Ivo reached its maximum intensity of and an estimated minimum pressure of 997 mbar (hPa; ) on September 12. The tropical storm moved toward the northwest and then west over increasingly cooler waters, and gradually weakened. It became a low-pressure system devoid of convection by the end of September 14. Tropical Depression One-C Tropical Depression One-C formed on September 11 more than southeast of the Big Island of Hawaii. The system moved west-northwestward to 15°N 153°W initially, and then shifted southwestward shortly thereafter. A poorly organized system, the convection of Tropical Depression One-C dissipated later on September 11, after having been a depression for only 12 hours. Hurricane Juliette An area of disturbed weather associated with the remnants of Atlantic Tropical Depression Nine organized directly into Tropical Storm Juliette in the East Pacific on September 21. Moving generally northwestward under
