Mississippi prepares for Isaac

In 2005, Mississippi's Gulf coast took the brunt of Hurricane Katrina, suffering damage estimated at more than a billion dollars, including at the key fuel facilities in Gulfport.

With other storms come and gone, residents are preparing for another: Hurricane Isaac, which reached windspeed powerful enough to become official overnight Tuesday.

Nobody seems to expect a storm with the same strength as Katrina, but residents are boarding up and hunkering down nevertheless.
