It lay 190 km south-southeast of Karaikal, 300 km south-southeast of Puducherry, and 400 km south of Chennai, and is very likely to continue to move north-northwestwards and reach over southwest Bay of Bengal near North Tamil Nadu, Puducherry and adjoining south Andhra Pradesh coasts by early morning of November 30, the weather bulletin said.

Private weather bloggers said there was no change in the cyclone’s track and that it moved parallel to the Tamil Nadu coast, and it would bring more rain over Chennai, Cuddalore and Puducherry by tonight.

The name, ‘Ditwah’, referring to a lagoon, was suggested by Yemen. It is likely named after Detwah Lagoon, a large, saline lagoon on the northwest coast of the island of Socotra in Yemen.
