Low Pressure System Over Bay of Bengal Triggers Flood Risk

Meteorologists at the India Meteorological Department have identified a low‑pressure system forming over the north‑western Bay of Bengal as the primary driver behind the heavy rain warning for Koyambalur, Nilgiri and Kanyakumari districts.

The system, still distant from the Tamil Nadu coastline, is expected to draw in moist air and amplify atmospheric circulation within the next 48 hours. This scenario is likely to increase rainfall intensity not only in the three highlighted districts but also across broader parts of the state.

Local administrations have been advised to monitor drainage networks, anticipate possible flash‑floods and prepare emergency response measures. Residents in vulnerable low‑lying or mountainous areas should keep abreast of updated advisories.

Additionally, the IMD forecasted moderate precipitation for the northern districts, Puducherry and Karaikal, while light to moderate rain could spread to other zones, offering some cooling effect.

The weather pattern is also expected to lower daytime temperatures modestly on Saturday and Sunday as cloud cover thickens and the rain‑bearing system exerts its influence.
