Severe Tropical Storm Delfina was a damaging tropical cyclone that affected southeastern Africa in January 2003. The fourth named storm of the 2002–03 South-West Indian Ocean cyclone season, Delfina formed off the northwest coast of Madagascar on December 30, 2002. It quickly intensified while moving westward, becoming a strong tropical storm before hitting northeastern Mozambique on December 31. Delfina weakened while moving inland, and it was no longer classifiable as a tropical cyclone by January 1, 2003. However, its remnants moved across the country and into Malawi, later looping around and crossing back over Mozambique; the remnants of Delfina were last observed on January 9.
