depression. The JTWC began monitoring the system by the next day, noting the presence of a consolidated low-level circulation within the system. The system's chances of developing into a tropical cyclone slowly increased, and on December 16 at 17:30 UTC, the JTWC issued a TCFA for the system despite the outflow of Typhoon Rai partially exposing the system's low-level circulation. By 21:00 UTC, the JTWC upgraded the system to a tropical depression, assigning it the designation 29W as it continued over marginally favorable developmental conditions. Shortly after, at 23:00 UTC, the depression made landfall north of Kuantan and began to weaken, prompting the JTWC to issue its final advisory on the system by the next day. The JMA stopped monitoring the system on December 17 at 12:00 UTC. After passing through Peninsular Malaysia, it reached the Straits of Malacca as a low-pressure system. Persistent and continuous heavy rains for more than 24 hours began on December 17, causing the worst flooding in Central Malaysia since 2014. Floods were also reported in the states of Kelantan, Terengganu, Pahang, Perak, Negeri Sembilan and Malacca. Other systems During January 19, the JMA reported that a tropical depression had developed to the east of Luzon, Philippines. The precursor to the depression brought scattered showers and thunderstorms to Mindanao, Palawan, and Visayas on January 18. The JMA, however, discontinued advisories for the system on the next day. The depression also brought stormy weather to Luzon on January 20. The PAGASA warned residents of possible flash flooding and mudslides due to heavy rainfall. The system's precursor was associated with a frontal system, with its combined effects bringing heavy rainfall over much of Visayas, the Bicol Region, and Northern Mindanao, resulting in three deaths and agricultural damages of up to ₱642.5 million (US$13.2 million). On March 9, a low-pressure area entered the Philippine Area of Responsibility, though it was not expected to develop at that time. On March 14, the low-pressure area intensified into a tropical depression over the Sulu Sea before quickly degenerating back into a low-pressure area. The system brought light to moderate rains over parts of the Philippines, with the PAGASA advising residents of the possibility of floods and landslides. On May 29, the JTWC issued a TCFA for a tropical disturbance that was roughly to the southeast of Guam, near the Nomoi Islands. The system gradually developed as it was experiencing warm sea
