Tropical Cyclone Charotte was spinning over the South Indian Ocean northwest of Australia on Tuesday night. At 11:00 p.m. EDT on Tuesday the center of Tropical Cyclone Charlotte was located at latitude 18.5°S and longitude 108.7°E which put it about 435 miles (700 km) northwest of Learmonth, Australia. Charlotte was moving toward the south-southwest at 6 m.p.h (10 km/h). The maximum sustained wind speed was 85 m.p.h. (135 km/h) and there were wind gusts to 105 m.p.h. (165 km/h). The minimum surface pressure was 973 mb.

Tropical Cyclone Charlotte continued to spin over over the South Indian Ocean northwest of Australia on Tuesday night. The environment around Charlotte became less favorable for a tropical cyclone on Tuesday evening and the tropical cyclone was beginning to be affected the different environment. The ring of thunderstorms around the eye weakened and the overall distribution of thunderstorms became asymmetrical. The strongest thunderstorms were occurring in bands in the southern half of the circulation around Tropical Cyclone Charlotte. Bands in the northern half of the tropical cyclone consisted primarily of showers and lower clouds. Storms near the center of circulation were still generating upper level divergence that pumped mass away to the southeast of the tropical cyclone. Winds to tropical storm force extended out 125 miles (200 km) from the center of Tropical Cyclone Charlotte.

Tropical Cyclone Charlotte will continue to be in an environment unfavorable for a tropical cyclone during the next several days. Charlotte will move over water where the Sea Surface Temperatures are near 28˚C. An upper level trough over the South Indian Ocean will approach Charlotte from the west. The trough will produce northwesterly winds that will blow toward the top of Charlotte’s circulation. Those winds will cause moderate vertical wind shear. The flow of air around Tropical Cyclone Charlotte could also pull drier air into the western and northern parts of the circulation. The wind shear and the drier air will cause Tropical Cyclone Charlotte to weaken during the next several days.

Tropical Cyclone Charlotte will move around the western part of a high pressure system over Australia during the next 36 hours. The high pressure system will steer Charlotte toward the south. On its anticipated track Tropical Cyclone Charlotte will move parallel to the coast of Western Australia. Charlotte will remain west of the coast during the next 36 hours.
