Chennai, Dec 16
The weather department has predicted heavy rain in the coastal districts of Tamil Nadu starting Tuesday.
The Regional Meteorological Centre (RMC) stated that a low-pressure area over the southeast Bay of Bengal is likely to become more pronounced and move west-northwestwards towards the Tamil Nadu coast in the next two days, bringing rainfall from Tuesday.
The low-pressure area is expected to form under the influence of an upper air cyclonic circulation over the south Andaman Sea and adjoining areas, including the southeast Bay of Bengal, the weather department said.
The RMC forecast heavy rain at many places over coastal Tamil Nadu and Puducherry with thunderstorms and lightning at isolated locations.
Heavy to very heavy rain is expected at isolated places over Cuddalore, Mayiladuthurai, Nagapattinam, and Tiruvarur districts, along with the Karaikal area.
The weather department also predicted heavy rain at isolated places in Chengalpattu, Villupuram, Kallakurichi, Ariyalur, Perambalur, Tiruchirappalli, Thanjavur, and Pudukkottai districts, as well as Puducherry.
On Wednesday, light to moderate rain is likely to happen across Tamil Nadu, Puducherry, and Karaikal, with thunderstorms and lightning at isolated locations, according to the RMC.
