On September 3, the JMA started to track a tropical depression that had developed to the east of Luzon, Philippines. During the next day, the PAGASA initiated advisories and gave the local name Kiko,[94] while the JTWC followed suit by giving it the designation 19W.[95] However due to increased wind shear along with an exposed circulation, the JTWC issued its final advisory on 03:00 UTC September 5.[96] Several hours later, deep convection was depicted and despite moderate to high shear, the JTWC re-initiated advisories,[97] while the JMA had upgraded the system to a tropical storm, naming it as Guchol early on the next day. On 21:00 UTC of that day, the JTWC stopped issuing warnings on the system after convection significantly weakened.[98]

On March 19, a tropical depression formed close to the northeast of Mindanao, Philippines, and dissipated over the Sibuyan Sea two days later.[100][101] Early on June 29, the JMA initiated advisories on a newly formed tropical depression located about 138 km (86 mi) south of Okinawa Island.[102] The system re-curved and started moving in a northeastward direction until it dissipated to the southwest of Tokyo on July 1.[103] Early on July 4, the JMA indicated that a tropical depression had formed about 505 km (314 mi) south of Okinotorishima.[104] During the next day, the JTWC issued a Tropical Cyclone Formation Alert (TCFA) on the system, although it was canceled several hours later.[105] After moving northward, the depression rapidly weakened as it was absorbed by a stationary front on July 7.[106]

Early on July 13, the JMA reported that a non-tropical low had transitioned into a tropical depression about 72 km (45 mi) north-northeast of Iwo Jima.[107] The depression moved in a generally northeasterly direction until weakening to a low-pressure area by 06:00 UTC on July 16.[108] A tropical depression formed about 691 km (429 mi) northeast of Wake Island late on July 25, though the JTWC indicated it as a subtropical system with estimated recorded winds of 65 km/h (40 mph).[109][110] After several days, the system had already transitioned into an extratropical cyclone on July 29, without becoming a tropical storm.[111] Early on August 25 the JMA started to track a tropical depression over in the South China Sea,[112] although it was last monitored during the next day when it got absorbed by the outflow of Tropical Storm Pakhar.[113] On August 28, the JMA started to issue advisories on a tropical depression that had developed about 1,217 km (756 mi) east-northeast of Tuguegarao City.[114] The JMA predicted that the system would become a tropical storm within the next 24 hours, although because the system did not develop further, the JMA issued their final advisory on 03:00 UTC of August 29 when the system had weakened into a low-pressure area.[115] The remnants of the system helped with formation of Tropical Storm Mawar.[116]
