This is not new news, but rather a month old one:

Note: the simulations had been done with ink, not oil. To check for oil
they would have to change the code, I think.
(...)
"I've had a lot of people ask me, 'Will the oil reach Florida?'" Synte
Peacock, one of the NCAR researchers who did the simulation, said in a
report on the early findings released by NCAR. "Actually, our best
knowledge says the scope of this environmental disaster is likely to reach
far beyond Florida, with impacts that have yet to be understood."
(...)
The simulations show that once the dye (and hence the oil slick) hits the
Loop Current, a fast-moving, clockwise whirl linking the tip of the
Yucatan Peninsula to the western edge of the Florida Panhandle, it can
quickly run up the Atlantic Coast as far north as Cape Hatteras in North
Carolina before being sucked out into the Atlantic where it disperses
across a wide area. So not only will the BP slick reach Florida, it will
absolutely engulf it. The Loop Current runs at about 40 miles per day, but
the Gulf Stream current in the Atlantic can do 100 miles per day, so the
oil could really move fast once it rounds the Panhandle, heading east.
The BP slick could have a dramatic effect on Europe as well. Martin
Visbeck, of the University of Kiel in Germany, is part of the team trying
to figure that out using these simulations. "Our assumption is that the
enormous lateral mixing in the ocean together with the biological
disintegration of the oil should reduce the pollution to levels below
harmful concentrations." Visbeck explained in the NCAR statement. "But we
would like to have this backed up by numbers from some of the best ocean
models."
