The India Meteorological Department (India Meteorological Department) on Tuesday issued a heavy rainfall alert for 10 districts of Tamil Nadu as a low-pressure area over the southwest Bay of Bengal near the Sri Lankan coast is expected to intensify over the next 48 hours. The system is likely to bring increased rainfall activity across parts of the state in the coming days.
According to the Regional Meteorological Centre (Regional Meteorological Centre Chennai), the weather system formed over the southwest Bay of Bengal is gradually strengthening and may evolve into a more active system. Officials, however, clarified that there is no immediate threat of severe weather conditions for Tamil Nadu at present.
The IMD has forecast moderate rainfall at isolated locations across southern coastal and delta districts over the next four days. The system is expected to enhance moisture inflow from the Bay of Bengal, resulting in intermittent showers and cloudy conditions in several regions. Meteorologists said the evolving conditions could influence weather patterns across both coastal and interior districts.

A heavy rain warning has been issued for May 15 and 16 for Nilgiris, Coimbatore, Erode, Tiruppur, Thanjavur, Tiruvarur, Nagapattinam, Pudukkottai, Ramanathapuram, and Sivaganga districts. The weather office has also warned of thunderstorms accompanied by heavy rainfall in these areas, with the possibility of intensified activity due to local convection and moisture build-up.
Authorities have advised fishermen to avoid venturing into the sea and to closely monitor weather updates, as rough sea conditions are likely in parts of the Bay of Bengal adjoining the Tamil Nadu coast. In Chennai, skies are expected to remain partly cloudy to generally cloudy over the next two days, with maximum temperatures likely staying below 37 degrees Celsius.
The latest weather developments come amid increasing pre-monsoon activity across southern India, with several regions already experiencing scattered rainfall, gusty winds, and thunderstorms. The IMD continues to monitor the low-pressure system closely as it tracks its movement and potential intensification over the Bay of Bengal.
