UPDATE 9/23: Via BoingBoing, a GoogleMaps plot of Hurricane Rita, "(Original Map Code by Ken Robinson. Enhancements, Dynamic Forecast Plots, other Modifications by Mike Cornelius Extra Graphics Tom Pratchios, Some ideas from compooter.org, Maps from Google Maps)."
Here's how it is really interesting: first, shift to the satellite view, and then zoom in on the area of the map where Rita shifted from a Category 4 to a Category 5 and back again. You can see that the shift corresponds to the level of the sea floor.
