The Regional Meteorological Centre (RMC) in Chennai has predicted rains in parts of Tamil Nadu, including Chennai. Light to moderate rain is likely to occur in Tamil Nadu and Puducherry between Sunday and Wednesday, the weather agency said.
According to a bulletin from the India Meteorological Department (IMD) on Sunday morning, the low-pressure area over Southeast Arabian Sea and adjoining the equatorial Indian Ocean now lies as a well-marked low-pressure area over the southeast and adjoining southwest Arabian Sea. It is likely to move west-northwestwards and concentrate into a depression (low-pressure system) during the next 24 hours, which means the weather will be cloudy and wet. Thunderstorm with lightning is likely to occur in isolated places over the state.
As far as Chennai is concerned, the Met Department said the sky condition is likely to be generally cloudy. Light rain is likely to occur in some areas. While the maximum and minimum temperatures will be between 29 and 25 degree Celsius respectively on Sunday, this is likely to vary between 30 and 26 degree Celsius on Monday.
Popular city-based weather blogger Pradeep John, who runs the Facebook page Tamil Nadu Weatherman, observed on Saturday that December is the weakest of the three northeast monsoon months.
According to the weatherman, apart from KTC (Kanchi, Tiruvallur and Chennai) belt, all across Tamil Nadu coast, right from Chennai to Tirunelveli coast, is likely to experience moderate rains from Sunday morning and also the next three days (Sunday to Tuesday).
“In the day time, the interior parts near the coast such as Vellore, Tiruvannamalai, Villupuram, Ariyalur, Thanjavur, Pudukottai and Sivaganga will get moderate rains here and there. In south Tamil Nadu, Tirunelveli, Theni, Virudhunagar and Dindigul will get some rains, too. In western Tamil Nadu, again Coonoor belt will get rains in the early mornings. Heavy rains, chance is less but if it has to happen, it has to be areas close to the sea in Ramanathapuram, Thoothukudi, ghats in Tirunelveli and the Coonoor belts,” he wrote.
