Background of Tamil Nadu flood 2015:

On 9–10 November 2015, Neyveli received 483 mm (19.0 in) of rainfall; rains continued to lash Cuddalore, Chidambaram and Chennai. Continuing rains led to low-lying parts of Chennai becoming inundated by 13 November, resulting in the evacuation of over 1000 people from their homes. On 15–16 November, Chennai received 246.5 mm (9.70 in) of rainfall, the highest amount recorded since November 2005, flooding most areas of the city.

The worst affected areas are located on the Coromandel Coast region of the South Indian states of Tamil Nadu, Andhra Pradesh and the union territory of Puducherry. Tamil Nadu the capital city of Chennai was particularly hard hit.

For the first time since its founding in 1878, the major newspaper The Hindu did not publish a print edition on 2 December, as workers were unable to reach the press building. The Southern Railways cancelled major train services and Chennai International Airport was closed until 6 December. The floods had killed nearly 600 people and displaced over 1.8 million people. 

Geographical analysis of  "2015 South Indian floods" :

What is Northeast monsoon ?

Around September, with the sun fast retreating south, the northern land mass of the Indian subcontinent begins to cool off rapidly. With this air pressure begins to build over northern India, the Indian Ocean and its surrounding atmosphere still holds its heat. 

This causes cold wind to sweep down from the Himalayas and Indo-Gangetic Plain towards the vast spans of the Indian Ocean south of the Deccan peninsula. This is known as the Northeast Monsoon or Retreating Monsoon.

Northeast monsoon the cause of Chennai Floods :

From October through December each year, a very large area of South India, including Tamil Nadu, the coastal regions of Andhra Pradesh and the union territory of Puducherry, receives up to 30 percent of its annual rainfall from the northeast monsoon (or winter monsoon).

Unlike during the regular monsoon, rainfall during the northeast monsoon is sporadic, but typically far exceeds the amount produced by the regular monsoon by up to 90 percent.

The coastal districts of Andhra Pradesh bear the brunt of really heavy rains during the northeast monsoon; with numerous river systems and wetlands, Puducherry and eastern Tamil Nadu are prone to flooding.

The city of Chennai alone experienced five major floods between 1943 and 2005, with the 1943, 1978 and 2005 floods causing particularly severe damage
