Cyclone Ivan was a powerful tropical cyclone that struck Madagascar in February 2008. Forming from a persistent area of convection on February 7, Ivan initially tracked southeastward, before looping to the west-southwest. Encountering favourable conditions, it strengthened to attain peak winds on February 17 before striking northeastern Madagascar. It degenerated into a remnant low pressure area as it crossed the island, and briefly re-organized into a weak tropical depression before dissipating on February 22.
