At 12:00 UTC on July 3, the PAGASA started to monitor a low-pressure area that developed near Torrijos, Marinduque or 149 kilometers to the south of Manila, followed by the Joint Typhoon Warning Center (JTWC)'s advisory at 01:00 UTC on the next day, citing the system's development as "low". In the latter's analysis on the disturbance, multispectral and microwave image scans on the system showed a weak low-level circulation center over the eastern part of Mindoro with flaring convection in the western periphery. Traveling northwestwards, the storm was located in an environment conductive for further intensification, with warm sea surface temperatures of , low wind shear around the region and good equatorial outflow; however, model forecasts were split regarding the disturbance's strengthening trend. Also that day at 15:00 UTC, the low-pressure area exited the Philippine Area of Responsibility (PAR), which was followed by the Japan Meteorological Agency (JMA) upgrading the storm to a tropical depression roughly three hours later. Eventually, the JTWC upgraded the system's potential intensification trend to "high" and subsequently issued a Tropical Cyclone Formation Alert at 00:30 UTC on June 6 as a circulation became well-defined. It then changed its motion towards the west along the periphery of a subtropical ridge on the north and northwest as it approached the Hainan Island. By 06:00 UTC on the next day, the disturbance moved inland on the region near Lingshui Li Autonomous County before emerging on the Gulf of Tonkin, in an area of low to moderate wind shear. Later, the disturbance began to reorganize; however, strong wind gradient suppressed its intensification, with flaring convection displaced to the west. Nine hours later, the JTWC upgraded the system to a weak tropical depression with maximum sustained winds of 45 km/h (30 mph); the JMA analysed the storm to be at 55 km/h (35 mph) and a minimum barometric pressure of 1000 hPa (29.53 inHg). By the night of that day, the depression, with the identifier 08W from the JTWC made landfall on Thanh Hoa, Vietnam on that intensity, before subsequently issuing their final warning as the agency confirmed that the system dissipated inland, with the evidences of radar and satellite imagery. The JMA continued to monitor the system until it dissipated at 00:00 UTC on July 8 over Laos.
