NOAA, Hurricane Ike Five Day Forecast (Line), World, 9/4/2008

The NHC official track forecast in shapefile format is an experimental products that the National Hurricane Center is testing during the 2008 hurricane season. This product will aid in the visualization of an NHC official track forecast, the forecast points are connected by black line segments. The track line(s) are not a forecast product, however, and because there are an infinite number of ways to connect a set of forecast points, the lines should not be interpreted as representing a specific forecast for the location of a tropical cyclone in between official forecast points. It is also important to remember that tropical cyclone track forecasts are subject to error, and that the effects of a tropical cyclone can span many hundreds of miles from the center.
