Tropical Storm Dianmu On September 21 at 18:00 UTC, the JMA noted a westward-moving low-pressure area over the South China Sea near the Philippines. Three hours later, the JTWC recognized this system. By 15:00 UTC the next day, the JTWC upgraded it to a tropical depression without issuing a TCFA for the system, as it rapidly improved its convective structure and developed a low-level circulation center; the JMA did the same three hours later. On September 23 at 06:00 UTC, the JMA upgraded it to a tropical storm and named it as Dianmu as it continued to move westward and come closer to the Vietnamese coastline. The JTWC did the same thing, three hours later.
