The Corps of Engineers Mississippi Valley New Orleans (MVN) continues to address the shoaling on the Crossings Above New Orleans and in the New Orleans Harbor. The MVN is working to restore full channel dimensions on the Crossings with the three dustpan dredges. Federally authorized channel dimensions on the Crossings Above New Orleans are 45 feet by 500 feet.
The graph below is reproduced from NOAA’s National Weather Service website and represents an experimental product to account for the complexity of accurately predicting long-range precipitation. This forecast projects stage levels based on expected precipitation for 2 days (top) and 16 days (bottom) and was developed within the North American Ensemble Forecast System (NAEFS) computer model and highlights Quantitative Precipitation Forecasts (QPF). Along with the forecasts, a shaded area is also provided to indicate uncertainty for the forecast each day in the future. These plots are experimental and not an official forecast product.
