NEW ORLEANS, La. - With a state of emergency in effect in Louisiana, the tropical threat in the Gulf of Mexico continues. The system gained strength overnight.
Louisiana officials have closed over 200 floodgates on the river in preparation as they face the levee system's biggest test since Katrina.
Meanwhile, residents are taking no chances. Mandatory evacuations are underway near the mouth of the Mississippi River and residents are stocking up on supplies and sandbags.
Oil companies are also pulling workers off rigs in the Gulf of Mexico.
