A well-marked low pressure area over southeast Bay of Bengal is expected to concentrate into a depression by Wednesday evening and bring in more rainfall to Tamil Nadu and south Andhra Pradesh that have been inundated with copious rains already for the past three days, the India Meteorological Department (IMD)said on Wednesday.

Ramanakumaran Theyyambet, a city resident and businessman who lives at Teynampet in Chennai while speaking to IANS said, "In 2015 there were heavy rains and we have all faced the repercussions of the deluge and in 2021 also if waterlogging and deluge is happening it means some serious introspection is necessary for those who are in the revenue and planning department as to why this is happening. It shows the utter callousness of our government bodies and the officials and the Chief Minister must take steps to have an action plan with a time frame ready to settle this issue forever."
