As the surge from Tropical Storm Barry piles up Gulf of Mexico waters off the mouth of the river, forecasters say the river will have nowhere to drain, and unseasonably-high water will start to back up in the river channel.

This is a foot lower than the previous forecast. Like the previous forecast, the river level is expected to increase dramatically Saturday morning, peak around 1:00 p.m., then fall just as quickly.

The river levees in the New Orleans area average around 20' high in some downriver areas, and in some spots it dips even lower.
