By Keith Evans / Assistant Marketplace EditorThree years after Hurricane Katrina devastated New Orleans, Mother Nature pulled another fast one on the Gulf Coast - 150 mph fast. Gustav, the second major hurricane of the 2008 Atlantic hurricane season, formed as a tropical depression on the morning of Aug. 25 off the coast of Haiti. Rapidly strengthening into a tropical storm that afternoon, Gustav survived a brief period of disorganization to develop a well-defined eye wall that same night. In the early hours of Aug. 26, multiple hurricane-hunter aircrafts confirmed that, with winds topping 90 mph, Gustav had become a full-fledged hurricane.
