Tropical Storm Ma-on Makes Landfall in Southeast China

Tropical Storm Ma-on made landfall in southeast China on Thursday morning. At 5:00 a.m. EDT on Thursday the center of Tropical Storm Ma-on was located at latitude 22.0°N and longitude 109.2°E which put it about 80 miles (130 km) east of Qinzhou. Ma-on was moving toward the west-northwest at 20 m.p.h. (32 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 994 mb.

Tropical Storm Ma-on made landfall on the coast of southeastern China between Dianbai and Zhanjiang on Thursday morning. The center of Ma-on made landfall near Wuchuan. Ma-on was a strong tropical storm at the time of landfall. The maximum sustained wind speed was 65 m.p.h. (105 km/h). The distribution of thunderstorms and heavy rain in Tropical Storm Ma-on was asymmetrical. Many of the thunderstorms with heavy rain were occurring in the southern half of Ma-on’s circulation. The strongest winds were occurring over the South China Sea. Winds to tropical storm force extended out 130 miles (210 km) from the center of Tropical Storm Ma-on.

Tropical Storm Ma-on will move around the southwestern part of a high pressure system over the Western North Pacific during the next 36 hours. The high pressure system will steer Ma-on toward the west-northwest. On its anticipated track Tropical Storm Ma-on will move inland over southeastern China and northern Vietnam. Ma-on will drop locally heavy rain over parts of southeastern China and northern Vietnam. Heavy rain could cause flash floods in some locations.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Tokage was weakening as it sped away from Japan. At 5:00 a.m. EDT on Thursday the center of Tropical Storm Tokage was located at latitude 41.3°N and longitude 153.9°E which put it about 610 miles (985 km) east of Misawa, Japan. Tokage was moving toward the northeast at 25 m.p.h. (40 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 987 mb.

Tropical Storm Ma-on Moves over South China Sea

Tropical Storm Ma-on moved over the South China Sea southeast of Hong Kong on Wednesday morning. At 5:00 a.m. EDT on Wednesday the center of Tropical Storm Ma-on was located at latitude 20.0°N and longitude 116.1°E which put it about 245 miles (395 km) southeast of Hong Kong. Ma-on was moving toward the west-northwest at 12 m.p.h. (19 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 984 mb.

Tropical Storm Ma-on maintained its intensity as it moved over the South China Sea southeast of Hong Kong on Wednesday morning. The inner end of a rainband wrapped around the southern and eastern sides of the center of Ma-on’s circulation. However, the distribution of thunderstorms in the rest of Tropical Storm Ma-on was asymmetrical. The strongest thunderstorms were occurring in bands in the southern and western parts of Ma-on. Bands in the eastern and northern parts of the circulation consisted primarily of showers and lower clouds. An upper level ridge over China was producing east-northeasterly winds that were blowing toward the top of Tropical Storm Ma-on. Those winds were causing moderate vertical wind shear and the wind shear was causing the asymmetrical distribution of thunderstorms.

Tropical Storm Ma-on will move through an environment somewhat favorable for intensification during the next 24 hours. Ma-on will move over water where the Sea Surface Temperatures are 29˚C. The upper level ridge over China will continue to cause vertical wind shear. If the vertical wind shear does not increase, then Tropical Storm Ma-on could strengthen during the next 24 hours. There is a chance Ma-on could strengthen to a typhoon.

Tropical Storm Ma-on will move around the southwestern part of a high pressure system over the Western North Pacific Ocean. The high pressure system will steer Ma-on toward the west-northwest during the next 36 hours. On its anticipated track Tropical Storm Ma-on could be south of Hong Kong in 12 hours. The center of Ma-on could make landfall on the south coast of China near Yangjiang and Dianbai in 24 hours. Tropical Storm Ma-on will bring gusty winds and locally heavy rain to southern China. Heavy rain could cause flash floods in some locations.

Elsewhere over the Western North Pacific Ocean, Typhoon Tokage was passing east of Japan. At 5:00 a.m. EDT on Wednesday the center of Typhoon Tokage was located at latitude 35.8°N and longitude 149.4°E which put it about 475 miles (770 km) east of Tokyo, Japan. Tokage was moving toward the north-northeast at 13 m.p.h. (20 km/h). The maximum sustained wind speed was 105 m.p.h. (165 km/h) and there were wind gusts to 125 m.p.h. (200 km/h). The minimum surface pressure was 961 mb.

Typhoon Chaba Hits Southern China

Typhoon Chaba hit southern China on Saturday morning. At 5:00 a.m. EDT on Saturday the center of Typhoon Chaba was located at latitude 21.5°N and longitude 111.0°E which put it about 25 miles (40 km) east of Wuchuan, China. Chaba was moving toward the north-northwest at 8 m.p.h. (13 km/h). The maximum sustained wind speed was 80 m.p.h. (130 km/h) and and there were wind gusts to 95 m.p.h. (150 km/h). The minimum surface pressure was 978 mb.

The center of Typhoon Chaba made landfall on the south coast of China near Wuchuan and Dianbai in Guangdong on Saturday morning. Typhoon Chaba was strengthening when it made landfall. A small circular eye was as the center of Chaba’s circulation. Winds to typhoon force extended out 60 miles (95 km) from the center of Chaba. Winds to tropical storm force extended out 190 miles (305 km) from the center of circulation.

Typhoon Chaba will move around the western end of a high pressure system over the Western North Pacific Ocean. The high pressure system will steer Chaba toward the north-northwest during the next 24 hours. On its anticipated track Typhoon Chaba will move inland over southern China. Chaba will weaken gradually as it moves inland. Typhoon Chaba will bring strong winds and locally heavy rain to southwestern Guangdong. Heavy rain could cause flash floods in some locations. There were reports a ship broke in two in heavy seas in the South China Sea.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Aere brought gusty winds and heavy rain to the center Ryukyu Islands. At 5:00 p.m. EDT on Saturday the center of Tropical Storm Aere was located at latitude 26.3°N and longitude 129.1°E which put it about 115 miles (185 km) east-southeast of Okinawa. Aere was moving toward the north-northwest at 17 m.p.h. (19 km/h). The maximum sustained wind speed was 50 m.p.h. (80 km/h) and and there were wind gusts to 65 m.p.h. (105 km/h). The minimum surface pressure was 994 mb.

Weakening Tropical Depression Nuri Makes Landfall West of Hong Kong

A weakening Tropical Depression Nuri made landfall on the coast of China west of Hong Kong on Saturday night.  At 11:00 p.m. EDT on Saturday the center of Tropical Depression Nuri was located at latitude 22.2°N and longitude 111.5°E which put it about 170 miles (280 km) west of Hong Kong.  Nuri was moving toward the northwest at 18 m.p.h. (29 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 1001 mb.

Former Tropical Storm Nuri weakened to a tropical depression as it approached the coast of China on Saturday night.  An upper level ridge centered over China produced northeasterly winds which blew toward the top of former Tropical Storm Nuri.  Those winds caused moderate vertical wind shear and they blew the tops off thunderstorms in the eastern half of Nuri.  The wind shear blocked upper level divergence to the east of the tropical storm and the surface pressure increased.  The wind speed decreased and Nuri was downgraded to a tropical depression as it neared the coast of China.

Tropical Depression Nuri moved around the southwestern part of a subtropical high pressure system over the Western North Pacific Ocean.  The high steered Nuri toward the northwest.  Tropical Depression Nuri made landfall on the coast of China west of Hong Kong.  The center of Nuri crossed the coast between Dianbai and Yangjiang.  The circulation around Tropical Depression Nuri will continue to weaken as it moves farther inland.  Nuri will bring some heavy rain showers to parts of southeastern China before it dissipates.
