 while the NPMOC issued warnings for tropical cyclones forming between 180° and the American coast. RSMC Nadi and TCWC Wellington both used the Australian tropical cyclone intensity scale, and measured windspeeds over a 10-minute period, while the JTWC and the NPMOC measured sustained windspeeds over a 1-minute period. For the first time this season, RSMC Nadi assigned a number and the letter F to each significant tropical disturbance that moved within the South Pacific basin, while the JTWC and NPMOC continued to assign a number and the letter P to significant tropical cyclones throughout their area of responsibility.

Tropical Disturbance 01F

On December 4, RSMC Nadi reported that Tropical Disturbance 01F had developed near Tuvalu, about 540 km northwest of Apia in American Samoa. The disturbance was weak and the final advisory was issued later that day.
