The JTWC soon followed, upgrading it into a Category 1-equivalent typhoon. At this time, a Champi turned north and north-northwestwards, and subsequently reached its peak intensity of 120 km/h (75 mph) ten-minute maximum sustained winds with a minimum barometric pressure of by 21:00 UTC on June 25, however it was downgraded to a tropical storm a day later. The storm continued to weaken as it move towards the Japanese islands, until on June 27, the JMA issued its last advisory at 12:00 UTC as the system became an extratropical low. The JTWC also issued its last warning for Champi at 09:00 UTC, same day. In the wake of the tropical depression, the National Weather Service in Guam issued a tropical storm watch for Rota in the Northern Mariana Islands and a tropical storm warning for the whole island of Guam on June 21. Marine and flash flood warnings were also posted on the former and on Saipan, Tinian, and other islands in the east and south, while classes on an elementary and a high school in the latter were suspended on the next day due to a reported power outage. Electrical disruptions were also experienced on Chalan Pago, Toto/Canada, and Santa Rita in Guam due to the system's near approach.

Tropical Depression 07W (Emong) On July 2, the JTWC started to monitor a tropical disturbance to the southwest of Guam. Moving northwestwards, the disturbance was located in an environment conducive for intensification in the Philippine Sea, with warm sea surface temperatures, and low wind shear, in addition to good poleward outflow, being induced by an upper-level trough to the northwest. The JMA upgraded the broad and weak system to a tropical depression at 18:00 UTC on the next day, followed by a TCFA being issued by the JTWC an hour and a half later.
