NBC NATIONAL NEWS — Hurricane Isaac is bearing down on the Gulf Coast.
Forecasters expect the storm to make landfall late tonight into early Wednesday morning, with
New Orleans straight in its cross-hairs.
Flood gates have been shut down and pumping stations are at the ready as the newly restored, and in many areas rebuilt, flood protection network waits for its first major test.
One of the primary concerns with this slow moving system is the massive amount of rain it could bring to a city already below sea level.
Ten to 16 inches of rain are forecast in some areas.
National Guard troops have already moved in.
"Whatever the situation may be, we're prepared," says Captain Mark Castillon. "We have a plan and we're waiting to execute that based on what happens."
Wind gusts of up to 125 miles per hour are expected as Isaac moves ashore.
