Tropical Storm Fung-wong clipped the southern part of Taiwan on Wednesday.  At 4:00 p.m. EST on Wednesday the center of Tropical Storm Fung-wong was located at latitude 23.5°N and longitude 122.5°E which put the center about 140 miles (225 km) south of Taipei, Taiwan.  Fung-wong was moving toward the northeast at 13 m.p.h. (21 km/h).  The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 1001 mb.

The center of Tropical Storm Fung-wong moved across southern Taiwan on Wednesday.  Fung-wong brought gusty winds and locally heavy rain as it moved across Taiwan.

Tropical Storm Fung-wong continued to weaken as it moved across southern Taiwan on Wednesday.  Drier air from Asia was pulled into many parts of Fung-wong’s circulation.  A few thunderstorms were occurring near the center of Tropical Storm Fung-wong.  Other thunderstorms were located northeast of the center where Fung-wong’s circulation was interacting with a frontal boundary.  There was little upper level divergence.  Since mass was not being transported away from Tropical Storm Fung-wong, the surface pressure was increasing.

The distribution of wind speeds around Tropical Storm Fung-wong was very asymmetrical.  The pressure gradient between a high pressure system over eastern Asia and Tropical Storm Fung-wong was causing a large area of tropical storm winds to the north of Fung-wong.  Winds to tropical storm force extended out 320 miles (520 km) in the northern side of Fung-wong’s circulation.  Winds to tropical storm force extended out 90 miles (145 km) in the southern side of Tropical Storm Fung-wong.

Tropical Storm Fung-wong will move through an environment that will be unfavorable for intensification during the next 24 hours.  Fung-wong will move over water where the Sea Surface Temperatures are near 27°C.  It will move under the southeastern part of an upper level trough that is over eastern China.  The upper level trough will produce southwesterly winds that will blow across the top of Fung-wong’s circulation.  Those winds will cause strong vertical wind shear.  In addition, the drier air that is already in the circulation around Fung-wong will suppress the formation of new thunderstorms.  Strong vertical wind shear and the drier air will cause Tropical Storm Fung-wong to continue to weaken during the next 24 hours.

Tropical Storm Fung-wong will move around the western end of a high pressure system that is over the Western North Pacific Ocean.  The high pressure system will steer Fung-wong toward the northeast during the next 24 hours.  On its anticipated track, Tropical Storm Fung-wong will move over the southern Ryukyu Island.

Tropical Storm Fung-wong will bring gusty winds and rain showers to the southern Ryukyu Islands.
