Severe Tropical Cyclone Ofa was considered to be the worst
tropical cyclone to affect
Polynesia since
Cyclone Bebe. The system was first noted on January 27, 1990, near Tuvalu, as a shallow tropical depression that had developed within the South Pacific Convergence Zone. The cloud pattern slowly organized, and on January 31, while located east of Tuvalu, Ofa attained cyclone intensity. Moving slowly southeast, Ofa developed storm-force winds. It attained hurricane-force winds on February 2. Cyclone Ofa reached peak intensity on February 4. Shortly after, its peak Ofa began to weaken over a less favourable environment. Ofa was declared an
extratropical cyclone on February 8, though the system was still tracked by
meteorologists until February 10.
