NEW ORLEANS (AP) - Government scientists say an outer edge of the massive Gulf of Mexico oil has reached a powerful current that could take it to Florida and beyond.
Tar balls have washed ashore as far east as Alabama.
Louisiana Gov. Bobby Jindal declared Wednesday that heavier oil is now soiling his state's coastal marshes.
Earlier waves of the slick had begun as a thin sheen before the thicker stuff starting washing ashore this week.
The governor inspected the Mississippi Delta by boat and swept a fishnet through water, holding up a chocolate-thick ooze.
The region is home to rare birds, mammals and a wide variety of marine life.
The president of coastal Plaquemines Parish, La., says the oil "has laid down a blanket in the marsh that will destroy every living thing there."
