Further, thundershowers have been occurring over Chennai since morning hours.
The experts reported that the rainfall is being caused by a cyclone formation over the Bay of Bengal off Sri Lankan coast and along the Tamil Nadu coast.
Dr S Balachandran, Director, Area Cyclone Warning Centre said, "We are expecting heavy rainfall in areas like Chennai, Tiruvallur, Nagapattinam, Kanchipuram, Tanjore, Tiruvarur and Ramanathapuram. The cyclone continues to be at the same place off the Sri Lankan coast. While the interior districts of Tamil Nadu will experience moderate rainfall, the coastal districts will receive heavy rainfall."
