Lingering effects of Hurricane Isaac in Louisiana include more than 20,000 electric customers still without power, an estimated 700 people still in shelters and gobs of weathered oil washing ashore along a stretch of coastline.
The Federal Emergency Management Agency said it has approved more than $10 million in individual and housing assistance for more than 4,800 families as of Wednesday morning.
Power outages were down from more than 900,000.
Entergy Corp. listed most of the outages in Jefferson Parish, with more than 6,000, and in hard-hit Plaquemines Parish, with more than 5,000.
Tar balls and broad mats of tar have been reported along several miles of Louisiana beaches. State officials are working to determine whether Isaac had churned up oil from the 2010 BP spill or another source.
Oil company BP PLC said it was too early to say if the tar came from oil that spewed into the Gulf of Mexico when the Deepwater Horizon rig exploded.
