Tropical Cyclone Indusa passed east of Rodrigues on Saturday. At 5:00 p.m. EDT on Saturday the center of Tropical Cyclone Indusa was located at latitude 24.7°S and longitude 70.4°E which put the center about 575 miles (930 km) east-southeast of Port Mathurin, Rodrigues. Indusa was moving toward the south at 23 m.p.h. (37 km/h). The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 100 m.p.h. (160 km/h). The minimum surface pressure was 982 mb.
Tropical Cyclone Indusa strengthened on Saturday as it passed well to the east of Rodrigues. Thunderstorms continued to form near the center of Indusa’s circulation. Bands of showers and thunderstorms were revolving around the center of Tropical Cyclone Indusa. Storms near the center of Indusa generated upper level divergence that pumped mass away from the tropical cyclone. The removal of mass caused the surface pressure to decrease.
The distribution of wind speeds around Tropical Cyclone Indusa became a little more asymmetrical on Saturday. Winds to hurricane/typhoon force extended out 25 miles (40 km) from the center of Indusa’s circulation. Winds to tropical storm force extended out 100 miles (160 km) in the eastern side of Tropical Cyclone Indusa. Winds to tropical storm force extended out 60 miles (95 km) in the western half of Indusa’s circulation.
Tropical Cyclone Indusa will move into an environment that will become unfavorable for intensification during the next 24 hours. Indusa will move over water where the Sea Surface Temperatures are near 24°C. It will move under the eastern part of an upper level trough that is southeast of Madagascar. The upper level trough will produce northwesterly winds that will blow toward the top of Indusa’s circulation. Those winds will cause the vertical wind shear to increase. Cooler Sea Surface Temperatures and more vertical wind shear will cause Tropical Cyclone Indusa to weaken on Sunday.
The upper level trough that is southeast of Madagascar will steer Tropical Cyclone Indusa toward the south-southeast during the next 24 hours. On its anticipated track, Tropical Cyclone Indusa will move rapidly farther away from Rodrigues.
