For several days during the week building up to Christmas 1977, a tropical disturbance persisted about 925 km (575 mi) to the northeast of Fiji and to the northwest of Samoa.[1] A distinct cyclonic circulation subsequently started to develop during December 23, while it was located about 740 km (460 mi) to the northeast of Vanua Levu. Over the next day the system moved south-westwards and passed within 75 km (45 mi) of Futuna, before it was named Anne by the FMS during December 24, as satellite pictures showed that a tropical cyclone was developing. During December 25, the winds were indirectly estimated to be off gale-force, as it passed south-westwards through the Fijian Islands.
