A hurricane was observed over the South Atlantic, where no tropical cyclone observed at all since 1960s when meteorological satellite observation began on March 27, 2004.
This extremely rare hurricane has observed by the Tropical Rainfall Measuring Mission (TRMM) satellite and the Aqua satellite. It was born east of Brazil on March 25, then moved westward as it grew, eventually hitting Santa Catorina, Brazil.

Figure 1 indicates the rain rate near the surface observed by the Precipitation Radar, PR(*1), on board the TRMM satellite, overlaid with cloud images derived from the Visible Infrared Scanner, VIRS. Red represents intense rain. There is no rain in the center of the hurricane.
