New Orleans, La. – The sheen is being tracked by the National Oceanic and Atmospheric Administration. Spokesman Charlie Henry says the oil is moving slowly and could break apart before hitting land.
"The bulk of the oil is still way away to the northeast - I'm sorry - to the northwest of the loop current, and that oil is not in the immediate future a threat to be feeling the influence of the loop current and move down."
Tar balls that washed ashore in the Florida Keys have been tested and officials says they did NOT come from the Deepwater Horizon well that's still gushing at the seabed.
