South Atlantic tropical cyclone
A small area of convection developed on a trough of low pressure in mid-January off Brazil. It organized and appeared to become a tropical depression on January 18. The next morning, it had a small amounts of convection near the center and well-defined bands, and the system, either a weak tropical storm or a strong tropical depression, likely reached its peak. Located 150 n miles southeast of Salvador, Brazil, it weakened as upper level shear, normal for the basin, prevailed. The depression moved inland on the 20th as a circulation with no convection, and dissipated the next day over Brazil, where it caused heavy rains and flooding. This would mark the first time in recorded history that two tropical cyclones (Catarina and the January storm) have been seen during the same year in the South Atlantic, and may be considered to make up the 2003-04 South Atlantic hurricane season.
