the JTWC upgraded from a monsoonal depression to a tropical depression. It was designated as 22W. Satellite imagery found that the LLCC had become exposed but still had a defined warm core. The system's center was also ragged. At 18:00 UTC, the JMA upgraded it to a tropical storm and named it Lionrock. Nine hours later, the JTWC did the same as the convection developed a curved pattern. Lionrock continued its trajectory, and between 09:00 UTC and 15:00 UTC of October 8, it made its first landfall over the island of Hainan. After making landfall, it briefly intensified a bit before weakening to its original intensity at 21:00 UTC. At 09:00 UTC of the next day, it crossed the island completely and entered the Gulf of Tonkin. On October 10, at 09:00 UTC, the JTWC downgraded it to a tropical depression and issued its last warning, as it made landfall near Cat Bi International Airport and its convection became disorganized over land. The JMA also downgraded it to a tropical depression at 06:00 UTC the same day, but continued to monitor it. The JMA last noted at 18:00 UTC of October 10. In its early stages of formation, the system passed through the central Philippines. As of October 7, the NDRRMC recorded three deaths and estimated agricultural damages were topped at ₱12.2 million (US$241,000). Severe Tropical Storm Kompasu (Maring) On October 6 of 18:00 UTC, the JMA noted that a low-pressure area had formed that was embedded in a large monsoonal circulation to the north of Palau. The system developed into a tropical depression at 00:00 UTC of the next day. At 09:00 UTC (17:00 PHT), the PAGASA issued its first bulletin for the first tropical depression and assigned it the name Maring. The JMA also noted the persistence of another, nearby tropical depression to its northeast, later named Nando. As it is embedded in the same monsoonal depression and due to its proximity, Nando began to merge with Maring, and therefore formed a rather broad and large circulation. This prompted the JMA to upgrade the overall system to a tropical storm, and was named Kompasu. However at that time, the JTWC still considered the system as two separate disturbances and issued separate TCFAs later in the day for both depressions, albeit noting the possibility of merging. The JTWC later considered the entire system as merged with their first warning
