The India Meteorological Department (IMD) has issued a warning for heavy rainfall across 16 districts in Tamil Nadu, including hilly and coastal areas. Intense showers are forecast to continue till October 19, with possible disruptions in transport and agriculture. Authorities have urged residents to remain vigilant.

The Regional Meteorological Centre (RMC) of the India Meteorological Department (IMD) in Chennai has issued an alert for widespread heavy rainfall in 16 districts of Tamil Nadu over the coming week. The forecast highlights intense rainfall activity affecting the Western Ghats, interior regions, and the city of Chennai, signaling a continuation of recent rain disturbances.

On October 14 and 15, heavy downpours are expected in the hilly areas of Coimbatore, Nilgiris, Theni, and Tenkasi. Additionally, the hill belts of Tiruppur, Erode, Dharmapuri, Salem, Namakkal, Karur, Dindigul, Madurai, Virudhunagar, Tiruchirappalli, Kallakurichi, and Tiruvannamalai districts will experience strong rain spells.

The heavy rain warning extends to the coastal districts of Kanniyakumari, Thoothukudi, Ramanathapuram, and Sivaganga, as well as various other districts, with isolated heavy showers forecast across Pudukkottai, Thanjavur, Tiruvarur, Nagapattinam, and Mayiladuthurai. Chennai itself may see moderate rain accompanied by thunder and lightning.

The persistent heavy rainfall is attributed to a low-pressure system over the southwest Bay of Bengal and easterly wind activity amplifying precipitation. Recent weeks have already witnessed flooding and landslides in several areas, prompting authorities to release water from reservoirs as precautionary measures.
