Wilma Late on October 30, the
Japan Meteorological Agency (JMA) reported that a
low-pressure area had formed near
Chuuk. On November 1, a tropical disturbance southeast of
Yap persisted within the low-pressure area, as well as JMA upgraded the system to a tropical depression east of
Palau late on the same day. However, the agency soon downgraded it back to a low-pressure only six hours later, when the system remained poorly organised with
convection confined to the western flank. Shortly after JMA upgraded it to a tropical depression near Palau again early on November 3, the
Joint Typhoon Warning Center (JTWC) issued a
Tropical Cyclone Formation Alert for the system. Only three hours later, the system was upgraded to a tropical depression and designated as
30W by JTWC, estimating it would intensify into a category 1 typhoon in the
South China Sea. In post-analysis, JTWC indicated that 30W had already become a tropical depression on November 2. Late on November 3, the
Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) upgraded the system to a tropical depression and gave it the local name
Wilma. On November 4, Wilma made landfall over
Surigao del Sur,
Philippines before 04:00
UTC, and JMA began to issue tropical cyclone advisories to the tropical depression in the
Bohol Sea since 06:00 UTC, expecting it to intensify into a tropical storm within 24 hours. Soon, PAGASA downgraded Wilma to a low-pressure area at 09:00 UTC. Interacting with the frictional effects by passing through the Philippines, the tropical depression still got slightly organisational improvement, and it began to accelerate westward. Late on the same day, it arrived at the
Sulu Sea, as well as it crossed
Palawan and arrived at the South China Sea early on November 5. According to the JTWC best track data, 30W was a tropical storm at 06Z and 12Z, while the low-level circulation centre was partially exposed with the bulk of deep convection located to the north at noon. Late on the same day, JTWC downgraded 30W back to a tropical depression for becoming increasingly fragmented. on November 8 On November 6, JTWC issued a final warning to 30W at 06:00 UTC, when the tropical depression began to erode further. Prior to making landfall over the area near
Phan Rang–Tháp Chàm,
Vietnam, JMA stopped issuing any tropical cyclone advisory to the tropical depression at noon, although it still remained its 10-minute maximum sustained winds at briefly. According to the JTWC best track data, 30W weakened into a tropical disturbance early on November 7, yet it developed into a tropical depression again at noon, when the system was entering the
Gulf of Thailand from the southernmost border of
Thailand and
Cambodia. Late on the same day, JTWC reported that the organisation and
vorticity of 30W had got better. Early on November 8, the tropical depression made landfall over the area about south-southwest of
Bangkok, Thailand. Since 06:00Z, JMA stopped monitoring because it moved out of the area of responsibility.
BOB 05 The system arrived at the
Andaman Sea by crossing the
Malay Peninsula before noon, but then deep convection over the low-level circulation centre dissipated rapidly. On November 9, the system slowed down, as well as easterly vertical
wind shear had become stronger over the system located southwest of
Yangon,
Burma, making it remain partially exposed and disorganised. The
India Meteorological Department (IMD) started to mention the system as a
low-pressure area on the same day, right before it emerged into the
Bay of Bengal. IMD upgraded it to a well-marked low-pressure area on November 11, yet a microwave imagery showed a broad low-level circulation centre with shallow
convection as well as dry air beginning to wrap around the western quadrants. On November 13, IMD upgraded the system to a depression and designated it as
BOB 05 at 00:00 UTC. The low-level circulation centre became fully exposed but well-defined on November 14, and deep convection was sheared to the northwest by moderate vertical wind shear which was offsetting easterly diffluent
outflow. On November 15, JTWC upgraded the system to a tropical cyclone and continued designating it
30W, when the low-level circulation centre was tightly wrapped but partially exposed with deep convection sheared to the west. It developed radial outflow, but moderate easterly vertical wind shear kept affecting the tropical cyclone. However, 30W was considered as a tropical cyclone only at 18Z in post-analysis. At 07:30 UTC, Depression BOB 05 made landfall over
Tamil Nadu, India, and it weakened into a well-marked low-pressure area overland at 00:00 UTC on the next day, right before emerging into the
Arabian Sea. The remnants became almost stationary and turned west-southwestward on November 20, before finally dissipating near
Socotra,
Yemen on the next day. ==Impact==
