According to the report:

Overflights in the past week have found only scattered patches of light sheen near the Mississippi Delta – an indication that aggressive efforts to capture and disperse the oil have been effective and that the remaining oil is naturally dispersing and biodegrading.

Around May 24, a large loop current eddy, called Eddy Franklin, started to “pinch off” and detach, from the loop current. For a number of weeks, Eddy Franklin and the loop current showed varying levels of connectivity. The eddy is now clearly disconnected from the loop current and will likely migrate to the west over the next few months. As of July 25, 2010, Eddy Franklin was more than 100 miles from the nearest surface oil associated with the Deepwater Horizon/BP source.

There is no clear way for oil to be transported to Southern Florida, the Florida Keys or along the East Coast of the United States unless the loop current fully reforms with Eddy Franklin, or moves northward, neither of which is likely to happen for several months. At that point, essentially all of the remaining surface oil will have dissipated.
