Gustav overtopping Industrial Canal barrier in New Orleans.

MSNBC is reporting that waters from Hurricane Gustav, now a Category 2 storm, have overtopped the Industrial Canal barrier in New Orleans, and FEMA Deputy Director Harvey E. Johnson has warned that New Orleans will be “at least partially flood[ed].” Officials have evacuated 2 million people from Louisiana, but an estimated 10,000 remain in New Orleans. Hurricane-force winds also “slammed into oil terminals around Port Fourchon,” which is southwest of New Orleans and where “56 percent of the imported and Gulf of Mexico oil entering the United States passes.”

Update:

CNN is reporting that Gustav has made landfall near Cocodrie, LA, southwest of New Orleans.
