The 1970–71 South Pacific cyclone season, in terms of severe tropical cyclones, was the least active season on record, with none of its six storms strengthening above Category 2 tropical cyclone intensity. It was a below average season, beginning late and ending early. The season officially began on November 15 and ended on April 30, but the first storm formed a month after that, on December 15. __TOC__

Tropical Cyclone Priscilla

During December 15, a small tropical depression developed about to the north of Yasawa-i-Rara in Fiji's Yasawa Islands. Over the next day, the system drifted westwards, before it started to move southwards and intensify further. The system subsequently became equivalent to a modern-day category 1 tropical cyclone, with 10-minute sustained wind speeds of 75 km/h (45 mph) during December 17. During that day, the system passed about to the west of Nadi and started to move south-eastwards and passed well to the south of Ono-I-Lau during December 18. The system was last noted during the next day, after it had moved below 25S and out of the tropics. It was thought that the system caused gale-force winds in parts of
