Cyclone Hina: Severe Tropical Cyclone Hina in March 1997 was the worst tropical cyclone to affect the South Pacific island nation of Tonga since Cyclone Isaac in 1982.  The system was first noted within the monsoon trough on March 11, 1997, as a weak shallow depression within the vicinity of Rotuma.  Over the next two days, the depression remained near Rotuma with no preferred movement, as it started to develop further within favorable conditions for further development.  The system was subsequently named Hina on March 15, after it had started to move eastwards and had passed to the southeast of Niulakita, Tuvalu.  During that day the system moved south-eastwards and impacted Wallis and Futuna, before it passed over Tonga's southern islands of Tongatapu and 'Eua during March 16.
