Chennai Weather: Cyclone 'Ditwah' Nears Coast; Red & Orange Alerts Across Tamil Nadu, Puducherry

Cyclone Ditwah is intensifying and nearing the coasts of Tamil Nadu, Puducherry, and south Andhra Pradesh, with landfall expected on November 30.

Cyclone Ditwah is now moving steadily along the Sri Lankan coastline and inching closer to the Bay of Bengal, prompting the India Meteorological Department (IMD) to issue red and orange alerts for several districts in Tamil Nadu, Puducherry and south Andhra Pradesh. The system is expected to make landfall on November 30, bringing intense rain, thunderstorms and gusty winds to large parts of the eastern coast.

Cyclone Strengthens as It Tracks Towards Bay of Bengal

According to IMD, Cyclone Ditwah has been steadily intensifying over the past 24 hours. As it moves north-northwest, the storm is likely to enter the southwest Bay of Bengal early on November 30—close to the coasts of north Tamil Nadu, Puducherry and south Andhra Pradesh.

Officials have urged people in coastal belts to stay updated, as conditions may worsen quickly depending on the cyclone's speed and movement. Fishermen have been specifically advised to stay away from the sea until further notice.
