It also time for the other cities to wake up. It took a Tsunami for India to realise that they need a tsunami warning system. Guess it was the first time in History that a tsunami hit INdia, but heavy rainfall is something every place in India can be affected by.
So I feel its high time the government wakes up and do something about drainage and other facilities not only in Mumbai but to the whole of India. Am sure I speak for the people of India when I say, people would get angry if the government gives the same answer next time "The city - X is not capable enough to handle rainfall"!
