depression at 03:00 UTC on the same day, with the JTWC doing the same at 09:00 UTC, designating it as 09W. On July 18 at 00:00 UTC, the JMA upgraded it to a tropical storm assigning it the name In-fa. The JTWC also upgraded it to a tropical storm at 03:00 UTC. The system had deep flaring convection, however its low-level circulation was broad and elongated. On July 18, at 00:00 UTC, the JMA upgraded the system to a severe tropical storm. In-fa started moving westwards, and as it gradually strengthened, In-fa developed a formative eye on July 20, at 03:00 UTC. At 09:00 UTC, the JTWC declared In-fa to have strengthened into a typhoon as it had deep convection and robust outflow. The JMA also followed suit and upgraded In-fa to a typhoon at 12:00 UTC because of good upper-level outflow and higher sea surface temperatures; however, its central dense overcast was still obscure. On the next day at 03:00 UTC, In-fa strengthened into a Category 2-equivalent typhoon as its central convection continued to deepen. The feeder bands became more compact and the eye of the typhoon became clearer and more defined. The JTWC assessed that it peaked as a Category 2-equivalent typhoon with maximum wind speeds of at 03:00 UTC the same day. Because of dry air, the JTWC later downgraded In-fa to a Category 1-equivalent typhoon at 03:00 UTC the next day despite the presence of warm sea surface temperatures and low wind shear. On July 23 at 21:00 UTC, In-fa got further downgraded to a tropical storm by the JTWC, as its eyewall became fragmented and the deep convection was not continuous over the eye; it later re-intensified into a Category 1-equivalent typhoon again at 03:00 UTC the next day as it regained convective depths and it managed to maintain a ragged eye. At 09:00 UTC, PAGASA issued its final advisory as Typhoon In-fa moved northwards and exited the PAR. On July 24, at 06:00 UTC, In-fa peaked as a typhoon with maximum 10-minute sustained wind speeds of and a minimum pressure of , according to the JMA. On the next day, the China Meteorological Administration (CMA) noted In-fa to have made landfall in Putuo Island at around 04:30 UTC. After making landfall, the JTWC downgraded it to a tropical storm at 09:00 UTC as it eye structure began to degrade. JMA later downgraded to a
