Severe Tropical Cyclone Isaac was a South Pacific tropical cyclone that severely affected Tonga in 1982. On February 27, the Fiji Meteorological Service started to monitor an area of low pressure within the South Pacific Convergence Zone to the southwest of Tokelau. It continued to develop northeast of Samoa while travelling southwest and was named Isaac after becoming a tropical cyclone on March 1. Isaac moved through the Haʻapai island group and only 50 km (31 mi) northwest of Tongatapu.
