Intense rain likely in coastal districts on November 10, 11

The low-pressure area will intensify into a depression; red alert in coastal districts

The coastal parts of Tamil Nadu may have to prepare for another spell of intense rain. The low-pressure area, which formed on Monday, will intensify into a depression and trigger extremely heavy rain over parts of the State. The India Meteorological Department has issued a red alert in several coastal and adjoining districts, including Chennai, for Wednesday and Thursday.

The low-pressure area is likely to become a depression over south-west and adjoining south-east Bay of Bengal by Wednesday. It may move west-northwestwards, reach near north Tamil Nadu coast in the early hours of November 11 and bring another spell of widespread rain in the State. The rain is expected to be extremely heavy in some parts.

While rain will cover most places of the State till November 13, the IMD has forecast heavy to very heavy rainfall — up to 20.4 cm — at a few places on Wednesday in nearly 11 districts, including Chennai and its neighbouring districts, Madurai, Tenkasi and Perambalur. The weather system may trigger an extremely heavy rainfall of above 20.4 cm at one or two places in the Cauvery delta districts and Cuddalore, Villupuram, Pudukottai, Sivaganga, Ramanathapuram, Puducherry and Karaikal. Heavy rain is possible in other districts like the Nilgiris and Vellore.
