 The Intertropical Convergence Zone (ITCZ) over the eastern Indian Ocean was the origin of what would become Tropical Storm Adelinina. On October 30, the JTWC began monitoring the system to the south of Diego Garcia, and classified it as Tropical Cyclone 01S on November 1. On the next day, the MFR began issuing advisories on the system and quickly upgraded it to Moderate Tropical Storm Adelinina. The agency estimated 10 ‑ minute winds of 65 km / h (40 mph) as the storm moved to the southeast. By contrast, the JTWC assessed that Adelinina rapidly intensified into the equivalent of a minimal hurricane on November 2, estimating peak 1 ‑ minute winds of 140 km / h (85 mph) the next day. Without strengthening further, Adelinina began weakening on November 4, turning to the east and later turning back to the northwest; the track was influenced by a ridge to the south. Adelinina completed its five-day loop on November 7 as it crossed westward over its former track. That day, the MFR re-upgraded the system to tropical storm status, but discontinued advisories on November 8.
