The TRMM satellite passed above weakening typhoon Guchol on 18 June 2012 at 2322 UTC as it moved toward Japan's main island of Honshu. Guchol's past and predicted locations are shown overlaid in white. A precipitation analysis from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments show that the Japanese islands of Kyushu and Shikoku were getting rainfall from Guchol at the time of that orbit. Guchol was shown by TRMM to be enhancing rainfall in parts of Japan over 500 km (~310.7 miles) from the typhoon's center.
