Tropical Storm Hagupit Almost a Typhoon

Tropical Storm Hagupit intensified to almost typhoon strength east of Taiwan on Sunday.  At 11:00 p.m. EDT on Sunday the center of Typhoon Hagupit was located at latitude 25.4°N and longitude 123.2°E which put it about 130 miles (215 km) east of Taipei, Taiwan.  Hagupit was moving toward the north-northwest at 10 m.p.h. (16 km/h).  The maximum sustained wind speed was 70 m.p.h. (110 km/h) and there were wind gusts to 85 m.p.h. (135 km/h).  The minimum surface pressure was 985 mb.

The circulation around Tropical Storm Hagupit exhibited much greater organization on Sunday night.  The inner end of a rainband wrapped around the center of circulation and an eye emerged on visible satellite imagery.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Hagupit.  The strongest rainbands were in the eastern half of the circulation.  Bands in the western half of the tropical storm consisted primarily of showers and lower clouds.  Winds to tropical storm force extended out 115 miles (185 km) from the center of circulation.

Tropical Storm Hagupit will move through an environment favorable for intensification during the next 24 hours.  Hagupit will move over water where the Sea Surface Temperature is near 29°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Tropical Storm Hagupit will intensify into a typhoon during the next 6 to 12 hours.

Tropical Storm Hagupit will move around the western end of a subtropical high pressure system over the Western North Pacific Ocean.  The high will steer Hagupit toward the north-northwest during the next 24 to 36 hours.  On its anticipated track Hagupit will approach the coast of China south of Shanghai near Wenzhou in about 24 hours.  It will bring gusty winds and locally heavy rain to the east coast of China.  Heavy rain could cause flash floods in some locations.

Elsewhere, former Tropical Storm Sinlaku dropped locally heavy rain on northern Vietnam and Laos.  At 2:00 p.m. EDT on Sunday the center of Tropical Depression Sinlaku was located at latitude 19.7°N and longitude 103.6°E which put it about 150 miles (240 km) north of Vientiane, Laos.  Sinlaku was moving toward the west at 10 m.p.h. (16 km/h).  The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h).  The minimum surface pressure was 996 mb.

Tropical Storm Yagi Makes Landfall on East Coast of China

Tropical Storm Yagi made landfall on the east coast of China between Wenzhou and Taizhou on Sunday.  At 11:00 a.m. EDT on Sunday the center of Tropical Storm Yagi was located at latitude 28.4°N and longitude 121.7°E which put it about 35 miles (55 km) south of Taizhou, China.  Yagi was moving toward the northwest at 16 m.p.h. (26 km/h).  The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 65 m.p.h. (105 km/h).  The minimum surface pressure was 987 mb.

Tropical Storm Yagi was moving steadily inland over Zhejiang province between Wenzhou and Taizhou.  The strongest winds were occurring in bands of thunderstorms east of the center of circulation that were over the coastal waters of the East China Sea.  The wind in those areas will diminish when Yagi moves farther inland.  The greatest risk will be locally heavy rain falling over parts of Zhejiang province.  Rainfall could be enhanced where the wind blows up the slopes of mountains and steep terrain increases the potential for flash floods.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Leepi moved closer to Iwo To and Tropical Depression 20W formed southwest of Hong Kong.  At 11:00 a.m. EDT on Sunday the center of Tropical Storm Leepi was located at latitude 24.1°N and longitude 141.2°E which put it about 85 miles (135 km) south-southeast of Iwo To.  Leepi was moving toward the north-northwest at 11 m.p.h. (17 km/h).  The maximum sustained wind speed was 55 m.p.h. (90 km/h) and there were wind gusts to 70 m.p.h. (110 km/h).  The minimum surface pressure was 992 mb.

At 11:00 a.m. EDT on Sunday the center of Tropical Depression 20W was located at latitude 20.7°N and longitude 112.4°E which put it about 85 miles (135 km) southwest of Macao.  It was moving toward the east-southeast at 3 m.p.h. (5 km/h).  The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h).  The minimum surface pressure was 996 mb.
