That's why low-lying areas are being asked to leave. Mississippi's gulf coast is bracing for the onslaught. On monday, some roads north, clogged. As gas lines lengthened. Long line, huh? Yeah, it is.

Reporter: Anything that can't be boarded up is being tied down or moved inside. This is a huge storm. Estimated to be 800 miles wide. That's huge. Reporter: In gulfport, the county has activated its 24-hour operational center. The national guard is now on stand-by. And electric companies are positioning trucks for anticipated outages. We're preparing for the worst and hoping for the best. Reporter: Seven years ago, katrina demolished gulfport. The casinos, the restaurants, almost everything that lines this coast.
