Widespread rain to continue

Intensity of rain will relatively reduce after Thursday: IMD

Widespread rain with moderate intensity will continue over the State till Deepavali day. Some areas in four districts are likely to receive very heavy rain on Wednesday, according to the India Meteorological Department.

The low-pressure area, persisting over the Comorin area and its neighbourhood, is likely to move north-northwestwards. Its movement is likely to influence rainfall over the State and Puducherry. Moreover, a trough from the weather system runs to west-central Bay of Bengal, off the south Andhra Pradesh coast, across the Gulf of Mannar and the Tamil Nadu coast.

The weather systems will help the rain spell last till Saturday. However, the intensity of rain would relatively reduce after Thursday, officials said. According to IMD, very heavy rain is likely to occur in isolated places of Tiruvallur, Kancheepuram, Chengalpattu and Tiruvannamalai districts on Wednesday. Several other districts may experience heavy rain in one or two places. Most other places, including Chennai, may receive moderate rainfall.
