This tuesday witnessed a second devastating hurricane attack after katrina.This huricane attack will actually be testing how foolproof were the flood defences already built. Although not as powerful as that of Katrina but Issac accompanied along with it a 80 mph or 120 kph winds following a heavy rainfall that is expected to flood the entire area. Katrina attack was considered as the costliest natural disaster that took in its lap the lives of nearly 1800 people. The Issac attack marking the 7 anniversaryof Katrina will be an acid test to prove how tight the disaster management system is working out there.Various preventive measures like walls,floodgates,levees and pumps built using $14.5 billion has already been implemented.The massive new floodgate at Lake Borgne which is the world's largest storm surge barrier has already been closed.The lower 9th ward of most of the cities scarred by Katrina memories has already been evacuted.This huricane is not only putting a halt in the lives of common mass but also shuttering the oil production at the US Gulf of Mexico.
