"The re-formation of the center has caused a big southward change ... and Gustav is now forecast to pass near the south coast of Jamaica," the U.S. National Hurricane Center said.
While the storm's eventual U.S. landfall could be anywhere from the Florida Panhandle to Texas, one of its likely tracks was west of New Orleans, the southern U.S. city devastated by Hurricane Katrina in 2005.
Gustav was projected to hit the U.S. Gulf Coast around Monday, two days after the third anniversary of Katrina, which killed 1,500 people and caused at least $80 billion in damage in several Gulf Coast states.
The NHC basically lost track of this storm overnight. The shift south is a pretty major move. It just reinforces the fact that you have to be prepared for anything when these storms are within a few hundred miles of your location.
