The India Meteorological Department (IMD) on Wednesday issued a red alert in Chennai even as the rainwater from the weekend spell has not receded from many parts of the city.
According to the weather forecast, Chennai and its neigbouring districts would see thunderstorms with heavy to very heavy rains on Wednesday and Thursday triggered by a weather system brewing in the southeast Bay of Bengal.
Meanwhile, the regional meteorological centre said the well-marked low-pressure area over the bay is likely to concentrate into a depression over the next 12 hours and move west–northwestwards and reach near north Tamil Nadu coast by the early morning of November 11.
"Thereafter, it is likely to continue to move west-northwestwards and cross north Tamil Nadu and adjoining south Andhra Pradesh coast between Karaikal and Sriharikota around Cuddalore by the evening November 11."
