Cyclonic storm Mandous which crossed the coast at Mamallapuram has weakened into a deep depression but the weather system impacted the city and its neighbourhoods, uprooting a number of trees.
Civic agencies, including the Greater Chennai Corporation were involved in removing the fallen trees. Power remained suspended in many parts of the city and the surroundings.
"The cyclonic storm Mandous (meaning treasure box) weakened into a deep depression over north Tamil Nadu coast. To move nearly west-northwestwards and gradually weaken into a depression by noon of 10th december," the IMD Chennai said in a tweet.
Tamil Nadu Revenue and Disaster Management Minister KKSSR Ramachandran, citing initial estimates, said there was no major damage as expected.
