Messing with hurricanes might not be a good idea anyway.
Be nice if you could steer them, but like most weather, hurricanes are nature's way of smoothing the heat out on our planet.
If you interrupted the cycle, like by somehow blocking evaporation from the Gulf, you'd screw something up. Odds are the Gulf would get even hotter, and either mess up its ecosystem, or brew up some kind of super-hurricane. It's kind of like economics.
