This satellite image shows Tropical Depression Isaac as it moved from the Gulf Coast towards the central United States. It was collected on August 31, 2012, at about 2:00 a.m. Central Daylight Time by the Visible Infrared Imaging Radiometer Suite (VIIRS) aboard Suomi-NPP. In addition to clouds illuminated by a nearly-full moon, the lights of cities and towns stand out from the darker landscape. A similar image taken after moonset on August 27 shows the area as it appeared before the storm.
NASA Earth Observatory image by Jesse Allen and Robert Simmon, using VIIRS Day-Night Band data from the Suomi National Polar-orbiting Partnership (Suomi NPP). Suomi NPP is the result of a partnership between NASA, the National Oceanic and Atmospheric Administration, and the Department of Defense.
