The 2015 Chennai floods resulted from heavy rainfall generated by the annual northeast monsoon in November–December 2015. They affected the Coromandel Coast region of the South Indian states of Tamil Nadu and Andhra Pradesh, and the union territory of Puducherry, with Tamil Nadu and the city of Chennai particularly hard-hit. More than 500 people were killed and over 1.8 million people were displaced. With estimates of damages and losses ranging from ₹50000 crore (US$7 billion) to ₹100000 crore (US$15 billion),the floods were the costliest to have occurred in 2015, and were among the costliest natural disasters of the year. The flooding has been attributed to the El Niño phenomenon and unannounced opening of Chembarambakkam reservoir, which is the water lifeline of Chennai. Irony is that Chennai suffers from water scarcity for most part of the year. Coovum, the major river of Chennai has breached its restricted boundaries and entered encroachments and slums built on its banks.Somewhere somebody is watching over us, observing our greed, desires, politics, carelessness towards nature and irresponsibleness. Only to correct us and guide us to prevent detours. Hope we learn from our mistakes and stop taking nature for granted!
