Heavy rainfall expected across Tamil Nadu including Chennai on October 18

The India Meteorological Department has forecast heavy rainfall across numerous districts in Tamil Nadu on October 18, with the state capital Chennai among the areas expected to receive substantial precipitation. The adverse weather is being driven by significant convective cloud activity developing over the north coastal Tamil Nadu region and adjoining sea areas, coupled with a cyclonic circulation system operating in the vicinity.

The combination of these atmospheric conditions has created favourable circumstances for widespread rainfall, prompting meteorological authorities to alert residents and administration officials across affected districts. The convective cloud development, characterized by strong vertical air movements, is expected to generate heavy downpours throughout the day.

Residents have been advised to exercise caution, particularly in low-lying and flood-prone areas. The meteorological department is expected to provide regular updates as the system evolves, with further bulletins likely to clarify the intensity and duration of the rainfall. Authorities in affected districts have been put on alert to manage potential disruptions to transport and civic infrastructure.
