Chennai / Tamil Nadu: The Regional Meteorological Centre, Chennai has forecast light to moderate rain at isolated places across Tamil Nadu through January 3, driven by moisture incursion from over the Bay of Bengal and a persistent atmospheric circulation.

IMD warnings indicate a rainfall alert today for parts of the state, with Coimbatore, Theni, Tenkasi and Nilgiris districts most likely to experience heavy showers and thunderstorms due to prevailing lower atmospheric cyclonic conditions.

Weather officials say that this unsettled pattern is linked to two active atmospheric circulations, which have already brought rainfall to some areas — and could continue to influence showers over the next few days.

The state’s forecast expects light to moderate rain continuing through today, especially across southern and western districts, before a gradual decline in rainfall after early January.
