late on august 22, an area of low pressure developed to the west of guam. at midnight that day, the system became sufficiently well organized that the jma started tracking it as a tropical depression. on august 23, the system moved into an environment of low wind shear and warm sea surface temperatures prompting the jtwc to issued a tcfa on it. by august 25, the system grew strong enough that the jma upgraded it to a tropical storm, naming it "talas". later that day, the jtwc followed suit and initiated advisories on talas. talas continued to strengthen and by midnight that day, it became a severe tropical storm. over the next few days, talas continued to drift north very slowly until late on august 29, when the jma upgraded talas to a typhoon. soon, a subtropical ridge to the west of the storm weakened and the subtropical ridge to the east of the system pushed talas to the west. as a result, talas accelerated towards the west maintaining strength and outflow. an upper-level cyclone over the system suppressed the convection and kept it from reaching the center. therefore, talas remained weak and did not strengthen further. convection never managed to consolidate the center and convective banding remained well away from the fully exposed low-level circulation center. the convective banding continued to expand more and more with the outer rainbands already brushing parts of japan. coastal areas in the nation have already reported gale-force winds several hours before landfall, while the omega block continued to drive talas towards the nation. land interaction weakened talas, prompting the jma to downgrade talas from a typhoon to a severe tropical storm with winds of under . early on september 3, talas made landfall over aki, japan. after landfall, talas accelerated north at over and its central convection became significantly eroded and was displaced to the northeast as talas was exposed to a very strong wind shear of over that made the llcc very distorted and difficult to pin-point. talas was embedded in a baroclinic zone and the jtwc anticipated an extratropical transition, which prompted them to issue their final warning on the system. on september 5, the jma issued their final warning on the system, reporting that talas has become extratropical on the sea of japan.
