Tropical Storm Rumbia Makes Landfall Near Shanghai, Bebinca Hits Vietnam

Tropical Storm Rumbia made landfall on the east coast of China just south of Shanghai on Thursday, and Tropical Storm Babinca hit Vietnam.  At 5:00 p.m. EDT on Thursday the center of Tropical Storm Rumbia was located at latitude 30.5°N and longitude 121.0°E which put it about 60 miles (95 km) southwest of Shanghai, China.  Rumbia was moving toward the west at 14 m.p.h. (22 km/h).  The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 75 m.p.h. (120 km/h).  The minimum surface pressure was 987 mb.

Tropical Storm Rumbia strengthened before it made landfall.  Thunderstorms developed near the center of circulation and a band wrapped around the center.  The circulation became more circular and storms near the center began to generate upper level divergence.  In the western half off the circulation where the winds were blowing toward the land, increased friction enhanced rising motion and heavier rain fell.

Tropical Storm Rumbia caused some gusty winds near the coast, but the greater risks were the locally heavy rain and the potential for floods.  Tropical Storm Rumbia is forecast to move slightly north of due west as it moves inland over eastern China.  Rumbia will drop locally heavy rain over the area around Shanghai, and over parts Zhejiang, Jiangsu and Anhui provinces.  Some of those regions have received heavy rain from previous storms and the potential for serious flooding exists.

Tropical Storm Bebinca made landfall on the coast of Vietnam on Thursday.  At 5:00 p.m. EDT on Thursday the center of Tropical Storm Bebinca was located at latitude 19.9°N and longitude 106.3°E which put it about 70 miles (110 km) southeast of Ninh Binh, Vietnam.  Bebinca was moving toward the west-southwest at 8 m.p.h. (13 km/h).  The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h).  The minimum surface pressure was 979 mb.

Tropical Storm Bebinca also strengthened before it made landfall.  An eye started to form at the center of circulation and Bebinca was on the threshold of becoming a typhoon when it made landfall.  Tropical Storm Bebinca produced gusty winds and a storm surge near the coast.  However, the greatest risks are locally heavy rain and the potential for floods.  Tropical Storm Bebinca is forecast to move in a general westerly direction.  Bebinca will drop locally heavy rain over parts of Vietnam, northern Laos and extreme northern Thailand.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Soulik moved quickly toward Iwo To and strengthened.  At 5:00 p.m. EDT on Thursday the center of Tropical Storm Soulik was located at latitude 20.9°N and longitude 141.3°E which put it about 315 miles (510 km) south of Iwo To.  Soulik was moving toward the north at 20 m.p.h. (32 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 981 mb.

Tropical Storm Rumbia Nears Shanghai, Bebinca Strengthens East of Vietnam

Tropical Storm Rumbia moved closer to Shanghai on Wednesday, while Tropical Storm Bebinca strengthened east of Vietnam and Tropical Storm Soulik formed west of Guam.  At 11:00 p.m. EDT on Wednesday the center of Tropical Storm Rumbia was located at latitude 30.1°N and longitude 124.2°E which put it about 160 miles (260 km) southeast of Shanghai, China.  Rumbia was moving toward the west-northwest at 7 m.p.h. (11 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 999 mb.

Tropical Storm Rumbia has about 12 to 18 hours before it makes landfall near Shanghai.  It will move through an environment somewhat favorable for intensification.  Rumbia will move over water where the Sea Surface Temperature is near 28°C.  The circulation of Rumbia is broad.  There is a distinct center of circulation, but there are few thunderstorms close to the center.  Most of the stronger thunderstorms were occurring in rainbands revolving around the center of Rumbia.  The broad circulation will limit the potential for intensification, but Tropical Storm Rumbia could get stronger before it reaches the east coast of China on Thursday.

Tropical Storm Bebinca strengthened on Wednesday while it moved south of China.  At 11:00 p.m. EDT on Wednesday the center of Tropical Storm Bebinca was located at latitude 19.9°N and longitude 108.2°E which put it about 125 miles (200 km) east-southeast of Hai Phong, Vietnam.  Bebinca was moving toward the west-southwest at 15 m.p.h. (24 km/h).  The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 75 m.p.h. (120 km/h).  The minimum surface pressure was 980 mb.

Tropical Storm Bebinca intensified quickly on Wednesday after it moved west of Hainan Island.  A primary rainband wrapped around the center of circulation and an eye appeared to be forming.  Several bands of showers and thunderstorms were revolving around the core of Bebinca.  Tropical Storm Bebinca has about 18 hours before it reaches the coast of Vietnam.  It will move through an environment favorable for intensification.  Bebinca will move over water where the Sea Surface Temperature is near 29°C.  It will move through an area where the upper level winds are weak and there is little vertical wind shear.  Bebinca could strengthen into a typhoon before it reaches Vietnam.

Tropical Storm Bebinca could make landfall on the coast of  Vietnam between Hai Phong and Vinh within 24 hours.  It could be a typhoon when it makes landfall.  Bebinca will bring strong winds capable of causing damage.  it could generate a storm surge of 6 to 9 feet (2 to 3 meters) at the coast.  Bebinca will drop heavy rain over parts of Vietnam and it could cause serious flooding.

Tropical Storm Soulik formed west of Guam on Wednesday.  At 11:00 p.m. EDT on Wednesday the center of Tropical Storm Soulik was located at latitude 15.9°N and longitude 142.7°E which put it about 165 miles (265 km) northwest of Guam.  Soulik was moving toward the north-northwest at 20 m.p.h. (32 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 999 mb.

Tropical Storm Soulik will move through an environment favorable for intensification.  Soulik will move over water where the Sea Surface Temperature is near 29°C.  It will move east of an upper level low that will produce southerly winds.  Those winds will move blow toward the top of the circulation and they will cause some vertical wind shear, but they will not be strong enough to prevent intensification.  Soulik could strengthen into a typhoon within 48 hours.  The upper low will pull Tropical Storm Soulik toward Iwo To.
