Coastal Tamil Nadu and Puducherry are bracing for Cyclone Nivar, which has intensified into a "severe cyclonic storm", expected to intensify further and is barrelling towards the southeast coast. The powerful cyclone is likely to hit the coast this evening between Mamallapuram in Tamil Nadu (which is around 56 km from state capital Chennai) and Karaikal in Puducherry. The cyclone has brought with it heavy rain and strong winds in coastal Tamil Nadu and Puducherry. On Tuesday, Prime Minister Narendra Modi tweeted to assure the Tamil Nadu and Puducherry governments - both have said today is a public holiday - of all possible support.
