NANGKA is the 78th name in the tropical cyclone name list. It was contributed by Malaysia, meaning jackfruit. This name was used in 2003 and 2009; the latter necessitated the #3 Strong Wind Signal in Hong Kong.
NANGKA made landfall in Shikoku last night, and is now crossing western Honshu. It has also weakened into a severe tropical storm. At 8 am, NANGKA was centred about 190 km (100 NM) W of Osaka.

NANGKA has crossed the ridge axis, and is expected to turn NE in the Sea of Japan, possibly making another landfall at northern Honshu or southern Hokkaido near t+48.

NANGKA has weakened over the past 24 hours. It will continue to weaken as it crosses Japan and enters the much cooler Sea of Japan. Extratropical transition is expected by t+72.
NANGKA is moving north steadily. At 8 am, NANGKA was centred about 540 km (290 NM) WNW of Iwo Jima.

NANGKA's eye expanded but is still ragged. As sea temperatures and shear conditions remain favourable, the storm is forecast to intensify in the next 12 hours. It will weaken as it approaches Japan and enters the cooler Sea of Japan, and will turn extratropical by t+96.
NANGKA is the 78th name in the tropical cyclone name list. It was contributed by Malaysia, meaning jackfruit. This name was used in 2003 and 2009; the latter necessitated the #3 Strong Wind Signal in Hong Kong.
NANGKA is currently moving north along the western periphery of the subtropical ridge. A finger of ridge extension at higher latitudes will provide slight westward track component in the next 72 hours, allowing NANGKA to move NNW. The storm is expected to move poleward again and recurve as it reaches Japan.
NANGKA underwent an eyewall replacement cycle yesterday as its inner eyewall became detached and shrank in size, which contributed to a temporary halt in its development. The storm is expected to intensify in the next 36 hours in an area of reduced shear and good divergence aloft. As ocean heat content decreases, NANGKA will weaken beyond t+48.

The subtropical ridge has weakened. NANGKA is about to turn north and will maintain such motion through t+36. The ridge is expected to strengthen again after t+36, and the storm should turn NW to NNW towards Japan.
NANGKA is maintaining a well-defined central dense overcast. The storm is expected to re-intensify in the next 72 hours as its outflow channel improves and vertical wind shear drops. It should weaken thereafter due to reduced ocean heat content.
NANGKA has weakened into category 3. At 8 am, NANGKA was centred about 730 km (400 NM) S of Iwo Jima.

As the subtropical ridge weakens, NANGKA will move slowly and turn north in the next 48 hours. The ridge is expected to strengthen again afterwards; a finger of extension will guide NANGKA towards the NW.
NANGKA's eye becomes cloud-filled. It is expected to weaken slightly in the next 24 hours due to elevated vertical wind shear. The storm may re-strengthen after the poleward turn as shear eases again.
NANGKA has intensified into a super typhoon. At 8 am, NANGKA was centred about 750 km (400 NM) S of Iwo Jima.

NANGKA will decelerate over the next 24 hours as the subtropical ridge weakens sharply. The storm will then turn north, moving slowly in the process. The ridge is expected to strengthen again near t+72; NANGKA should turn west afterwards.

NANGKA will move WNW along the southwestern periphery of the subtropical ridge in the next 48 hours. The ridge will break down rapidly, leading to a sharp deceleration and poleward turn between t+48 and t+72. The ridge is forecast to strengthen again, leading NANGKA towards the NW or NNW towards the end of the forecast period.
NANGKA is expected to strengthen slightly in decent environment in the next 36 to 48 hours, but may weaken later due to an increase in vertical wind shear.

NANGKA is situated in the southwestern periphery of the subtropical ridge, and is expected to move WNW in the next 48 to 72 hours. It will slow down and turn north after that as the ridge retreats.
NANGKA developed a clear eye yesterday, but has since become shallower. It is still expected to intensify slightly in decent environment, but may weaken later due to an increase in vertical wind shear.
