What advantage does this gives over the graphics given by NOAA/NWS/NHC: <a href="http://www.nhc.noaa.gov/graphics_at3.shtml?5-daynl?large#contents" rel="nofollow">http://www.nhc.noaa.gov/graphics_at3.shtml?5-daynl?large#con...</a> ? The information provided is a proper subset of that given by NHC (obviously, since NHC is almost certainly the source), it doesn't seem to be as recent, and the presentation is somewhat unbalanced - why give a high-resolution map if the margin of error covers maryland, delaware, and half of virginia?
