of , allowing it to develop a deep and symmetric core surrounded by deep convection. At this time, the JMA stated that Nanmadol had intensified into a severe tropical storm. The PAGASA also upgraded Nanmadol to a severe tropical storm in their final advisory on the system as it exited the Philippine Area of Responsibility. Nanmadol continued to intensify while moving northward just to the east of Taiwan, with satellite imagery capturing a small, developing eye. At 06:00 UTC on July 3, Nanmadol reached its peak intensity with the JTWC assessing the cyclone to have 1-minute sustained winds of 110 km/h (70 mph); the JMA estimated 10-minute sustained winds of 100 km/h (65 mph) and a minimum barometric pressure of . However, the JTWC assessed that Nanmadol reached its peak intensity as a Category 1-equivalent typhoon with 1-minute sustained winds of 120 km/h (75 mph) six hours later in a post-analysis report. Nanmadol maintained its peak intensity for several hours until just before July 4, when the system began curving eastwards and its satellite presentation deteriorated. Around that time, Nanmadol made landfall approximately 40 km (25 mi) to the east of Nagasaki in Kyushu. Despite the system still displaying a well-defined center, cloud tops began to warm, in line with the rapid weakening trend of the system. After several hours, Nanmadol began to interact with the mid-latitude westerlies; the JTWC downgraded the system further to a low-end of tropical storm intensity, though the JMA still maintained it at severe tropical storm intensity. By 21:00 UTC on the same day, the JTWC issued its final advisory on Nanmadol, mentioning that the system was embedded within the cold baroclinic zone, and had thus lost its tropical characteristics and transitioned into a cold-core low. The JMA soon followed suit with their final warning, declaring that Nanmadol had fully become an extratropical cyclone at 00:00 UTC on July 5. Its extratropical remnants later left the basin on July 8. Preparations, impact, and aftermath The JMA issued a heavy rain warning for Shimane Prefecture and neighboring areas, in which the government had urged 20,000 residents to evacuate. On July 3, the Sasebo City Emergency Management Bureau activated a total of 30 emergency shelters. The government dispatched a total of 12,000 rescuers, including police officers, firefighters and the Self-Defense Forces troops, in preparation for post-storm relief. On July 10, the Kyushu Railway Company began a bus
