Chennai, March 12 The Regional Meteorological Centre (RMC) on Wednesday issued a heavy rainfall warning for southern Tamil Nadu.
The downpour is attributed to a trough of low pressure over the southwest Bay of Bengal, near the Tamil Nadu coast, extending up to 1.5 km above sea level. As a result, isolated heavy rainfall is expected in the Kanniyakumari, Tirunelveli, and Thoothukudi districts.
The Meteorological (MeT) department has also predicted very heavy rain in these regions, as well as in the Tenkasi district. Fishermen have been advised against venturing into the sea due to the risk of cyclonic storms. Cloudy skies are expected across Tamil Nadu and Puducherry. In Chennai and its surrounding areas, the sky will remain partly cloudy, with light to moderate rain accompanied by thunderstorms and lightning in some parts of the city.
On Tuesday, Tamil Nadu experienced heavy rainfall following an orange alert issued by the RMC. Several districts reported significant showers, affecting normal life while benefiting summer crops such as pulses, peanuts, and maize.
