Tropical Cyclone 01B weakened over the Bay of Bengal on Saturday. At 4:00 p.m. EST on Saturday the center of Tropical Cyclone 01B was located at latitude 11.2°N and longitude 82.8°E which put it about 160 miles (260 km) east-southeast of Chennai India. It was moving toward the west at 4 m.p.h (6 km/h). The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h). The minimum surface pressure was 1003 mb.

Tropical Cyclone 01B weakened over the southwest Bay of Bengal on Saturday. The inflow around the western side of the tropical cyclone pulled drier air that was over India into Tropical Cyclone 01B. The drier air circulated around the tropical cyclone and it caused many of the thunderstorms to dissipate. A few thunderstorms persisted in a band northeast of the center of circulation. The other bands consisted primarily of showers and lower clouds. The dissipation of thunderstorms resulted in a circulation that was present only in the lower atmosphere.

Tropical Cyclone 01B will move through an environment unfavorable for intensification during the next 24 hours. The tropical cyclone will move over water where the Sea Surface Temperatures are near 28˚C. However the drier air will continue to inhibit the formation of new thunderstorms. The tropical cyclone will move under the western part of an upper level ridge centered over southeast Asia. The ridge will produce southeast winds that will blow toward the top of the depression. Those winds will cause moderate vertical wind shear and the shear will also inhibit intensification. Tropical Cyclone 01B is likely to continue to weaken as the circulation spins down. It could bring rain showers to southern India early next week.
