If you read the article you will see that it entirely failed to predict what just happened in Houston. The article goes on and on about Storm Surges, and building Dikes - neither of which had anything to do with what just happened.
ghshepard, true. The article focused on seawalls and surges, but still managed to get the damage correct: 600,000 residents effected, $100 Billion in damage, 145 mph winds. Regardless, knowing the effects of the storm -shown through the simulation - there could have been a plan for the ensuing catastrophe, e.g. evacuating the city, relief efforts; which seem ad hoc.
