the JTWC declared Holly an extratropical cyclone on September 15, with the JMA following suit two days later. The remnants of the typhoon lost its identity late on September 17. Throughout its lifetime, Typhoon Holly had no effects on land. Typhoon Ian Typhoon Ian began as broad and poorly organized tropical disturbance situated roughly east-northeast of Guam. At the time, the disturbance was embedded in the Western Pacific monsoon trough, which re-established itself after being disrupted by the previous tropical cyclone outbreak. Pressures in the area gradually fell start on September 21. Based on Dvorak classifications of T2.0/, the JMA and JTWC both classified the disturbance as a tropical depression early on September 23. At 18:00 UTC that day, both agencies upgraded the depression into Tropical Storm Ian. Tracking westward, Ian strengthened at a climatological rate of one T number per day. After Ian turned to the northwest, the JMA upgraded Ian into a severe tropical storm at 00:00 UTC on September 25. Despite lacking an inner core, Ian was believed to have attained typhoon intensity that same day by both the JTWC and JMA, and subsequently, entered a period of rapid deepening. The JTWC estimated that Ian deepened by over the next 24 hours. Data from the JTWC indicated that Ian peaked in intensity at 00:00 UTC on September 26, with winds of . The JMA suggested, however, the Ian's peak was much lower, with winds of . While leveling off in intensity, Ian's forward motion decreased as it tracked northward. The storm's slow motion caused the typhoon to upwell cold water, which contributed to a decrease in cloud top temperatures around the eye. On September 29, Ian began to recurve out to sea, in response to a shortwave trough passing north of the typhoon. The JMA downgraded Ian to a severe tropical storm that evening. The JTWC estimated that Ian transitioned into a subtropical cyclone on October 1, and the next day, Ian was downgraded into a tropical storm by the JMA. On October 4, Ian finally dissipated over to the east of Japan. Tropical Depression 17W Typhoon Peke On September 28, Hurricane Peke crossed the International Date Line and was thus re-designated as Typhoon Peke at 00:00 UTC that day. At the time of crossing, the JMA estimated winds of while the JTWC estimated winds of . In response to improved circus outflow, Peke steadily intensified, and
