Bhubaneswar, Oct 23: The India Meteorological Department (IMD) on Thursday said that the well-marked low-pressure system over Bay of Bengal, which was earlier expected to intensify into a depression, is now likely to weaken into a low-pressure area within the next 12 hours.

Earlier, the regional weather office had predicted that the system would intensify into a depression. However, it is now expected to move northwestwards into interior Tamil Nadu and then west-northwest, with a likelihood of weakening into a low-pressure area within the next 12 hours.

The wind direction will change due to the low-pressure effect, leading to increased humidity. There is also a possibility of rain accompanied by thunder and lightning at several places across the state, said the Regional Meteorological Centre in Bhubaneswar.

Taking to its X handle, IMD informed, “The well-marked low pressure area over north coastal Tamil Nadu and neighbourhood moved west-northwestwards and lay over north interior Tamil Nadu & neighbourhood at 2330 hrs IST of yesterday, the 22nd October 2025. It is likely to continue to move west-northwestwards across north interior Tamil Nadu weakened into a low-pressure area during next 12 hours.”
