Power cut was effected in several regions considering safety. The rains also caused damage to roads and causeways.
The flooding witnessed in Chennai for the past four days threw normal life out of gear as closed, inundated subways and traffic diversions gave people a harrowing time.

Chennai and several other northern regions witnessed heavy rains since Wednesday night and the depression moved close towards the city on Thursday, with showers intensifying in several areas.
Authorities used heavy duty motors, robotic excavators and deployed full manpower to pump out water, de-clog drains, remove trash and clear uprooted trees. As civic, revenue, public works, police and fire personnel slogged to help people and mitigate flood woes, Chief Minister M K Stalin said he bowed before all government workers involved in relief and rescue operations for their services to the people.

The bylanes of Pudupet, near the swollen Cooum river, Choolai, Semmancherry, Kodambakkam, KK Nagar-MGR Nagar and Arumbakkam were among the innumerable neighbourhoods hit by the deluge.
The streets around Hasthinapuram, close to suburban Chrompet resembled an angry speeding river, with water level raising over three-feet.

The inundation hit neighbouhoods like those off Mudichur, Perungalathur and Nandivaram-Guduvancherry appeared like mini islands with little access to essential needs and power supply was disconnected in all such areas considering safety.
A woman who was riding a scooter on the road abutting Raj Bhavan was injured when a tree fell. She was rushed to a hospital by authorities and the fallen tree was cleared.
Besides Chennai and its suburbs which fall under the districts of Chengelpet, Tiruvallur and Kancheepuram, other regions of the state including the northern belt too received heavy rainfall.
