Heavy showers to be triggered by cyclonic circulation
Area cyclone warning centre director S Balachandran said the rainfall would be triggered by an upper air cyclonic circulation over the Bay of Bengal off the Sri Lanka coast.
As a result, coastal districts like Chennai, Cuddalore, Kancheepuram, Nagapattinam, Ramanathapuram, Thanjavur, Thiruvallur and Tiruvarur will get heavy to very heavy rains.
Some interior districts would witness downpour too.
