The Regional Meteorological Centre predicts rainfall in parts of Tamil Nadu from Sunday to January 9. Recent weather-related disruptions have affected the state, with scattered rainfall recorded in some locations. Nalumukku in Tirunelveli district received the highest rainfall at 5 cm in the past 24 hours.
Meteorologists attribute the expected rainfall to prevailing atmospheric systems over the surrounding seas. A low-level atmospheric trough persists over the southeast Arabian Sea, near the southern Kerala coast. Additionally, an upper-air cyclonic circulation is active over the southeast Bay of Bengal and adjoining southwest Bay regions, likely causing intermittent light rain in isolated pockets of Tamil Nadu, Puducherry, and Karaikal.
In addition to rainfall, a decrease in night temperatures is anticipated. The IMD warns of a 2 to 4 degrees Celsius drop in minimum temperatures across Tamil Nadu, Puducherry, and Karaikal until January 7. This may lead to cooler early mornings than usual for this time of the year.
The forecast follows a challenging weather phase for Tamil Nadu in recent months. Heavy rainfall episodes due to cyclonic systems and northeast monsoon activity caused waterlogging, flooding, and crop damage in various districts. While the current forecast indicates light rainfall, authorities advise caution, especially during early morning and late evening hours when temperatures may further decrease.
