A tropical cyclone called Rusty developed in the Indian Ocean north of north-western Australia's coast on February 24, 2013. The TRMM satellite viewed the intensifying tropical cyclone when it flew over on February 25, 2013 at 0750 UTC. A rainfall analysis from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) with that orbit is shown overlaid on a visible/infrared image from TRMM's Visible and InfraRed Scanner (VIRS). This analysis showed that Rusty had an extensive area of rainfall surrounding Rusty's very large eye. TRMM PR and TMI instruments found that rain within wide bands of

Tropical cyclone Rusty's winds had increased to hurricane intensity when the TRMM satellite flew directly above on February 26, 2013 at 0654 UTC. A rainfall analysis derived from TRMM data is shown with the first image. Rain rates in the center of the swath are from the TRMM PR, while those in the outer swath are from the TRMM Microwave Imager (TMI). The rain rates are overlaid on a combination infrared (IR) visible (vis) image derived from the TRMM Visible Infrared Scanner (VIRS). TRMM PR found that the heaviest surface rain was coming down at a rate of over 138mm/hr (~5.4 inches). This
