 A tropical disturbance originated just east of St. Brandon on March 23 , initially consisting of a disorganized area of convection without a distinct center . Moving briskly westward , it slowly organized , becoming Moderate Tropical Storm Jinabo on March 25 . That day , the JTWC classified the system as Tropical Cyclone 19S .

On March 26 , the JTWC upgraded Jinabo to the equivalent of a minimal hurricane , and early the next day , the MFR estimated peak 10 ‑ minute winds of 115 km / h ( 70 mph ) .

Quickly weakening , Jinabo was only a minimal tropical storm by March 29 . On the next day , it turned back to the south . Jinabo weakened to tropical depression status on March 31 and dissipated the next day , having become extratropical and joining the <unk> .
