Though the Cyclone Ditwah has triggered heavy downpour across Tamil Nadu and neighbouring Puducherry, weather experts have some good news. Cyclone Ditwah has weakened.
According to private meteorologist Pradeep John, the Ditwah cyclone has turned into an empty vortex without any cloud cover. “The top clouds have been shaved off with only the low-level circulation (empty shell) remaining,” he said in an X post, adding that some clouding is likely to come back at night to tomorrow morning. “Chennai and the surrounding district and Ranipet will have some chance of rain as the cyclone moves closer to Chennai later at night,” he said, adding that the dying cyclone can give some more rains before fizzling out in open seas.

In an earlier post, he predicted that dry air and vertical wind shear had killed the cyclone, weakening the depression. “The depression circulation is still there as an empty shell without any clouds. Models expect clouding to come back later in the day around the KTCC (Chennai belt), Vellore, Ranipet, etc, in North Tamil Nadu,” he said.
Other weather bloggers, too, have predicted that the cyclone would weaken into a deep depression. "The cyclone will weaken further into a deep depression and then to a depression inching northward. It is expected that the system to stay in the open water for one more day, dissipating on the Chennai coast without making landfall," another private blogger said.
Meanwhile, the latest update by the Regional Meteorological Department issued on Sunday said the cyclone moved nearly northwards with a speed of 5 kmph and it is located about 80 km east of Karaikal, 100 km northeast of Vedaraniyam, 160 km southeast of Puducherry, and 250 km south of Chennai. It is likely to move northwards parallel to the North Tamil Nadu-Puducherry coasts during the next 24 hours.
It is expected that the storm will be centered over the southwest Bay of Bengal within a minimum distance of 50 km and 25 km from the Tamil-Nadu-Puducherry coastline by Sunday.
