The Regional Meteorological Centre (RMC), Chennai, has issued a weather alert forecasting widespread rainfall across Tamil Nadu for the next four days, due to the formation of a low-pressure area over the southeast Bay of Bengal and the adjoining South Andaman Sea.
As per the RMC, the low-pressure system is currently situated over the South Andaman Sea and nearby southeast Bay of Bengal. It is expected to intensify into a well-marked low-pressure area by October 21, moving in a west-northwestward direction and gradually strengthening as it nears the Tamil Nadu coast.
Consequently, light to moderate rain accompanied by thunder and lightning is likely in many parts of Tamil Nadu and Puducherry.
Isolated heavy rainfall is also expected, especially in the hilly areas of Coimbatore district, as well as in The Nilgiris, Erode, Tiruppur, Theni, Tenkasi, Tirunelveli, and Kanniyakumari districts.
For Monday, the forecast indicates heavy rainfall at isolated locations in Chengalpattu, Villupuram, Cuddalore, Mayiladuthurai, Nagapattinam, Tiruvarur, Thanjavur, Pudukottai, Ramanathapuram, Kallakurichi, and parts of Coimbatore and Erode districts.
Moderate rainfall is also likely in Madurai, Dindigul, and Virudhunagar districts, along with the union territories of Puducherry and Karaikal.
On October 21, heavy rain is anticipated in a few areas of Villupuram, Chengalpattu, Cuddalore, Mayiladuthurai, Nagapattinam, and Puducherry-Karaikal.
As the system intensifies, rainfall is expected to increase in both coastal and interior districts. A red alert has been issued for October 22 for northern coastal Tamil Nadu.
Districts such as Tiruvallur, Chennai, Chengalpattu, Kancheepuram, Villupuram, and Ranipet are likely to experience heavy to very heavy rainfall. Other districts including Cuddalore, Kallakurichi, Tiruvannamalai, Tirupattur, and Vellore may also witness heavy downpours.
