Army and Air Force teams have been deployed in Tamil Nadu to aid the district administration in relief and rescue work.
Severe torrential rains have led to flooding that has killed more than 70 people in the state and left more than 2000 people stranded.
Personnel from the Madras 4 Regiment of the Indian Army have been pressed into service at Mudichur in Kancheepuram . The Army is also aiding the evacuation process, as the India Meteorological Department (IMD) has warned of more rains in the next 24 hours.
The Air Force too has deployed sorties to rescue citizens, Defence officials said. IAF helicopters from the Air Force station at Tambaram carried out six sorties and evacuated 22 persons on Monday night. The sorties airdropped food packets and water in the severely inundated areas.
Normal life in as many as 25 districts has been hit. Schools, colleges and offices in all the water-logged areas continue to remain shut.
Several locals are still said to be stranded in Tiruvallur and Kancheepuram where heavy rains have inundated a large part of suburban Tambaram area. Adding to the woes, surplus water from lakes and tanks in Mudichur has also entered Tambaram.
Apart from Army and Air Force teams, a 160-member NDRF team, and 3 teams from the State Disaster Response Force are also carrying out relief work in Kancheepuram. Cuddalore too is said to be one of the worst-affected areas.
Locals are also being evacuated from Kotturpuram and nearby low-lying areas in Chennai, as the Adyar river continues to overflow after surplus water from Chembarambakkam lake was let into the river.
In Chennai, corporation workers are said to be working over-time to clear water-logged areas. Most subways, except for six, were cleared by Monday evening, according to authorities.
