A new low-pressure area developing over the Southwest Bay of Bengal, close to the Sri Lanka coastline, is expected to bring a fresh spell of intense showers to Tamil Nadu over the next two days. As per the latest update from the India Meteorological Department, the weather system, which formed early today, is likely to bring significant moisture from the sea. This will lead to widespread rain, thunderstorms and occasionally heavy downpours across several districts.
The Met Department has warned that heavy to heavy rainfall is predicted at isolated locations in Tamil Nadu on November 16 and 17. The influence of the developing system will be most strongly experienced over the next 48 hours.
