The Regional Meteorological Centre, Chennai has issued a red alert warning for Cuddalore, Mayiladuthurai, Thanjavur, Tiruvarur, Nagapattinam and Karaikal on Friday. It has withdrawn its earlier warning issued for Tiruvallur, Kancheepuram and Ranipet districts.
Speaking to presspersons on Friday, Additional Director General of Meteorology, Regional Meteorological Centre (RMC), Chennai, S. Balachandran said that light to moderate rain can be expected at most places with isolated thunderstorms and lightning likely over Tamil Nadu, Puducherry and Karaikal. The State will receive widespread rain for three more days.
Heavy to very heavy rain is likely to occur at isolated places over Tiruvallur, Chennai, Vellore, Ranipet, Kancheepuram, Chengalpattu, Tiruvannamalai, Villupuram, Puducherry, Kallaikurichi, Tirupattur, Krishnagiri, Dharmapuri, Salem, Perambalur, Ariyalur, Tiruchi, Pudukkottai, Sivaganga and Ramanathapuram districts.

This is due to the low-pressure area (LPA) over the Southwest Bay of Bengal off the Sri Lankan coast, which has now become a well-marked LPA over the Southwest Bay of Bengal and adjoining areas of northeast Sri Lanka with an associated upper air circulation extending up to 7.6 km above mean sea level.
The well-marked LPA is very likely to move northwestwards towards Tamil Nadu and Puducherry coasts until Saturday morning. Thereafter, it is likely to move west northwestwards across Tamil Nadu and Puducherry and Kerala during Saturday and Sunday and emerge into the southeast and adjoining east-central Arabian Sea as a Low-Pressure Area/ upper air circulation on Sunday, said Mr. Balachandran.
