by September 14 only a band of cirrus clouds remained in association with Uleki. The JTWC issued their final warning on the system at 00:00 UTC that day accordingly. The JMA maintained the system as a tropical depression as the former typhoon began turning to the east. Uleki later transitioned into an extratropical cyclone on September 16 as it accelerated to the east. The system dissipated the following day near the International Date Line, far from any major landmasses. Typhoon Hal An area of disturbed weather developed to the west of Wake Island. Over the next two days, Hal slowly organized as it tracked westward, with both the JTWC and JMA declaring the disturbance a tropical depression on September 8 well to the southeast of Japan. Moving to the northwest, Hal intensified into a tropical storm on September 9, according to both the JTWC and JMA, and then turned to the southeast on September 10. The JTWC declared Hal a typhoon that day, with the JMA following suit the following day. Midday on September 11, Hal attained peak intensity. There was significant difference between the two agencies, however, as the JTWC reported winds of and the JMA estimated winds of . Early on September 12, Hal sharply recurved, first turning to the north-northwest and eventually northeast on September 15. Accelerating northeastward, Hal became an extratropical cyclone on September 17, and the JMA stopped tracking it the next day. As an extratropical cyclone, Hal restrengthened before moving through the eastern Bering Sea on September 19 and into Alaska on September 20. The weakening low moved on an anticyclonic path through southern Alaska before emerging into the Gulf of Alaska on September 23. The cyclone drifted erratically southward, dissipating in the Gulf of Alaska on September 25. During its formative stages, Hal brought winds of up to to Guam, which caused minor property damage and scattered power outages. Severe Tropical Storm Irma Part of a mid-September tropical cyclone outbreak, Tropical Storm Irma originated from an area of disturbed weather developed on September 11. The same day, an increase in convection prompted the JTWC to issue a TCFA while the JMA upgraded it to a tropical depression. Based on objective intensity estimates of , the system was classified as a tropical storm by the JTWC and JMA at 00:00 UTC on September 12. Aided by outflow from Typhoon Hal, Irma steadily deepened.
