Flooding in the Midwest

NASA has provided us with a couple of images that speak volumes about the extent of the flooding in the midwest, particularly where the Mississippi River joins the Ohio.  Take a look here:  http://earthobservatory.nasa.gov/IOTD/view.php?id=50475&src=eorss-iotd on their Earth Observatory site.  The article that follows the pictures is also interesting, and helps shed light on what has happened there in the past two weeks.
