 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 .
