Tar balls wash ashore Gulf coastline after Isaac

LOUISIANA -- People continue to return home in Louisiana a week after Hurricane Isaac hit.

They're battling sweltering temperatures and no air conditioning.

Some 100,000 people along the gulf coast are still without power. The Louisiana governor's office said at least 13,000 homes were damaged during the storm and that number is expected to rise.

Two years after the Deepwater Horizon oil spill, tar balls are littering beaches, along Louisiana’s Gulf Coast.

Officials are closing off a section of coastline. All commercial and recreational fishing is prohibited within the closed area, except for recreational and charter boat angling.

Samples will be analyzed to determine if the tar is connected to the 2010 oil spill.
