Typhoon MA-ON had weakened to a strong tropical storm with wind speeds of about 60 kts (69 mph) when the TRMM satellite again flew over on 19 July 2011 at 2348 UTC. The rainfall analysis above using TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) data was overlaid on a daylight visible/infrared image from TRMM's Visible and InfraRed Scanner (VIRS) instrument. It reveals that although weaker MA-ON was dropping heavy rainfall over southern areas of the Japanese Island of Honshu. A red tropical storm symbol shows the location of MA-ON's center of circulation at that time. Click here to see earlier TRMM information about MA-ON.
