History

Historical Context

In November 2015, the Chennai floods, triggered by unprecedented monsoon rains, inundated the city and claimed over 500 lives across the metropolitan area. The India Meteorological Department recorded 1,200 mm of rainfall in Chennai during those three days, while the state government allocated INR10 billion for emergency relief. Today's yellow alert for seventeen Tamil Nadu districts mirrors the 2015 crisis, as low-pressure systems again threaten the Bay of Bengal and coastal communities. Repeated flood episodes underscore the need for upgraded drainage, stricter zoning, and sustained investment to prevent future humanitarian and economic losses.
