A low-pressure area has developed over the Bay of Bengal, prompting the Indian Meteorological Department to forecast heavy rainfall across Tamil Nadu over the coming 48 hours.
The Indian Meteorological Department (IMD) reported the formation of a low-pressure area over the Bay of Bengal on Monday, noting that the system is expected to intensify as it moves westward. Meteorologists have highlighted the favourable sea‑surface temperatures and prevailing wind patterns that support rapid development of the disturbance.
IMD’s weather outlook projects widespread heavy to very heavy rain across most districts of Tamil Nadu within the next 48 hours, with the greatest intensity likely along the coastal belt and interior river basins. Rainfall accumulations of 70‑100 mm are possible in places such as Chennai, Cuddalore and Tirunelveli, raising the risk of localized flooding.
Authorities have issued advisories urging residents to stay alert, avoid low‑lying areas, and secure outdoor belongings. The state disaster management agency has placed emergency response teams on standby and is monitoring water‑level rises in rivers and reservoirs.
Travelers are cautioned that road conditions may deteriorate, especially on state highways and bridges prone to waterlogging. The IMD will provide hourly updates as the system evolves, and the public is advised to follow official bulletins for the latest information.
