.
The disturbance had a broad low-level circulation center with convection starting to consolidate and was developing along the monsoon trough in favorable conditions.
Later that day both the
(PAGASA) and the
Japan Meteorological Agency
The Japan Meteorological Agency (JMA; ''気象庁, Kishō-chō'') is a division of the Ministry of Land, Infrastructure, Transport and Tourism dedicated to the Scientific, scientific observation and research of natural phenomena. Headquartered ...
(JMA) reported that the disturbance had become a tropical depression with PAGASA assigning the name of Maring to the depression as the low-level circulation center became more developed.
The next morning, the JTWC designated the tropical depression as 14W after the system had rapidly consolidated with deep convective bands forming in the low-level circulation center.
The depression was steered by a low to mid-level ridge to the northeast, however, a deeper secondary ridge was expected to assume steering the system to the northeast as it moved out of PAGASA's area of responsibility.
During that day, the depression rapidly developed, being changed to a tropical storm status by the JMA early on 10 September. JMA assigned the international number of 0913 and the name Mujigae to the storm.
However, at that time, Mujigae's low-level circulation center was partially exposed with convection confined to the western portion of the low-level circulation center due to a moderate amount of vertical wind shear associated with an anticyclone to the northeast of Mujigae. This affected the system which prevented Mujigae from further intensifying.
Mujigae then made landfall early the next day and passed over Northern

with observations from
Meilan, Hainan, showing that Mujigae was a Tropical depression.
However, the JMA did not downgrade Mujigae to a tropical depression at this time. As Mujigae moved into the

, the low-level circulation center became less organized with the JTWC forecasting that Mujigae would dissipate within six hours of making landfall on Vietnam.
Mujigae then made landfall on Vietnam early on 12 September.
The JTWC then issued their last advisory with the JMA downgrading Mujigae to a tropical depression and their final advisory as Mujigae's remnants had dissipated.

Abra under the Public Storm Warning Signal One before cancelling all of the signals later that morning. PAGASA also warned residents living in low-lying areas and near mountain slopes to take all the necessary precautions against possible flash floods and landslides.
In western Luzon, including Manila, a 48-hour rainfall was recorded when the depression was just forming. The depression enhanced the southwest monsoon that brought torrential rains to the area. In Laguna, two children were killed due to landslides caused by torrential rains brought by ''Maring''. Late on 8 September, both the JMA and the PAGASA declared the system was a minor tropical depression. On 9 September, all classes in Manila were suspended due to incessant rain and flooding. The National Disaster Coordinating Council reported that at least three villages in Malabon were submerged in 18 inch deep floodwaters. At least four streets in the area were impassable for light vehicles. Six provinces were given Public Storm Signal Number One.
In

, 15 low-lying barangays located in the city's first district were submerged. In Bulacan, five towns and two cities were flooded with water levels reaching four feet. In Bataan, the town of Dinalupihan was placed under the state of calamity after 22 barangays were affected by flash floods. In Pampanga, the NDCC placed the towns of Santa Ana, San Luis, Minalin, Mexico, Macabebe, Masantol, Apalit, Guagua, Sasmuan, Lubao, and Bacolor in state of calamity due to swelling rivers in Tarlac.
More than 300,000 residents of four northern provinces were affected by floods, including about 3,300 people who fled to evacuation centers and more than 41,000 who moved in with their relatives and friends. Overall, damages were estimated at 25 million
Philippine Peso in agricultural land.
Hainan Island
As Mujigae made its landfall over the Hainan island, the storm had caused economic losses of 56.43 million yuan (8.3 million U.S. dollars), with more than 50,000 people evacuated and some farmland, fish ponds, roads, and water conservation systems submerged. Flights at the Meilan Airport in the province's capital of Haikou were suspended on Thursday afternoon because of strong winds and heavy rains. All inbound and outbound train services in Hainan were suspended.

Early the next day, the standby signal was replaced with
Storm Signal Number 3, which meant that strong winds were expected to affect the city.
Signal 3 stayed in force for 13 hours, until it was replaced with the Storm Signal 1, then was cancelled two hours later.
