The India Meteorological Department (IMD) has predicted extremely heavy rainfall for some parts of Tamil Nadu and the adjoining Andhra Pradesh on November 10 and 11. As per the warning, the downpour is expected to inundate roads and may cause riverine flooding due to the depression forming over the Bay of Bengal.
