Image made August 13 and released September 1 by the National Aeronautics and Space Administration of then Tropical Storm Katia, which has since become a hurricane as seen from the International Space Station and photographed by one of the Expedition 28 crew. The storm, which is the second hurricane of the 2011 Atlantic hurricane season, is currently a category 1 storm but is expected to strengthen considerably but it is too early to determine what landfall the storm will make if any. Two Russian spacecraft, a Progress and a Soyuz, can be seen parked at the orbital outpost on the left side of the image.
