Tropical Cyclone Bebe was a pre-season storm that impacted the Gilbert, Ellice, and Fiji island groups.[1] First spotted on October 20, the system intensified and grew in size through October 22. Its course began along a south-southwest trajectory before recurving near the 14th parallel south, which resulted in a south-southeast motion through the western portion of the Fiji island group.[1] It became the first cyclone to impact Fiji since 1952. On October 24, winds of 150 knots (280 km/h) or more were reported on Rotuma and Viti Levu. Cyclone Bebe passed through Funafuti on Saturday 21st and Sunday 22 October 1972. At about 4 p.m. on the 21st, sea water was bubbling through the coral on the airfield with the water reaching a height of about 4 –5 feet high. The Ellice Islands Colony's ship Moanaraoi was in the lagoon and survived, however 3 tuna boats were wrecked. Waves broke over the atoll. Five people died, two adults and a 3 month old child were swept away by waves, and two sailors from the tuna boats were drowned.[2] Cyclone Bebe knocked down 90% of the houses and trees. The storm surge created a wall of coral rubble along the ocean side of Funafuti and Funafala that was about ten to twelve miles long, and about ten to twenty feet thick at the bottom.[2] The cyclone submerged Funafuti and sources of drinking water were contaminated as a result of the system's storm surge and fresh water flooding. After passing by the archipelago, Bebe transitioned into an extratropical cyclone, with the remnants last noted on October 28.[1] A total of 28 people died and thousands were left homeless. Damages totaled $20 million (1972 USD).[3]
