The swollen waterways and extensive flooding across the Ohio and Mississippi River valleys was captured from NOAA’s Joint Polar Satellite System (#JPSS) #satellite, #NOAA21. In these before and after images, the darker #flood waters can be easily seen yesterday following days of non-stop #rainfall across the region.
