URBAN FLOOD MANAGEMENT
- Record amounts of rain have hit Chennai and other parts of northern Tamil Nadu. A low-pressure area over the Bay of Bengal has meant that Tamil Nadu, coastal Andhra Pradesh and parts of Sri Lanka have been battered by rainfall.
- Among the reasons being given for the flooding in Chennai is the volume of rainfall: during the first 24 hours of heavy rain, Chennai received 246.5 mm rainfall, breaking the record of November 2005 which saw 142.4 mm. The highest rainfall during the north-east monsoon was in November 1976, when the city recorded a rainfall of 452.4 mm
