As it draws closer to the Gulf Coast, Isaac is bringing back memories of another devastating storm: Hurricane Katrina.
Though Isaac is far less powerful than the 2005 hurricane that crippled New Orleans, it is on an eerily similar path and forecast to make landfall on the seventh anniversary of Katrina. That's raising familiar fears and old anxieties in a city still recovering from a near-mortal blow seven years ago.
During Katrina, Linda Grandison fled her family's flooded home and waited on a bridge for more than three days before being rescued by helicopter. This time, she'll stay with her mother in the New Orleans suburb of Gretna.
New Orleans now has a bigger, better levee system and other improvements designed to endure all but the most destructive storms.
