Typhoon Bebinca Brings Wind and Rain to Ryukyu Islands

Typhoon Bebinca brought wind and rain to the Ryukyu Islands on Saturday.  At 11:00 a.m. EDT on Saturday the center of Typhoon Bebinca located at latitude 28.5°N and longitude 128.6°E which put the center about 65 miles (105 km) west-northeast of Amami Oshima.  Bebinca was moving toward the northwest at 15 m.p.h. (24 km/h).  The maximum sustained wind speed was 75 m.p.h. (120 km/h) and there were wind gusts to 90 m.p.h. (145 km/h).  The minimum surface pressure was 973 mb.

Former Tropical Storm Bebinca strengthened to a typhoon as it passed over the Ryukyu Islands on Saturday.  The center of Typhoon Bebinca passed over Amami Oshima.  A weather station in Naze, Japan reported 8.76 inches (222.5 mm) of rain.  A weather station in Kasari, Japan reported 4.80 inches (122.0 mm) of rain.  That weather station also reported a sustained wind speed of 52 m.p.h. (84 km/h).  A weather station in Koniya, Japan reported 3.33 inches (84.5 mm) of rain.  That weather station also reported a sustained wind speed of 39 m.p.h. (63 km/h).

Former Tropical Storm Bebinca strengthened to a typhoon on Saturday.  The inner end of a rainband wrapped around the eastern, northern and western sides of the center of Bebinca’s circulation.  Bands of showers and thunderstorms were revolving around the core of Typhoon Bebinca.  Storms near the core generated upper level divergence that pumped mass away from the typhoon.  The removal of mass caused the surface pressure to decrease.

The circulation around Typhoon Bebinca became more symmetrical on Saturday.  Winds to typhoon force extended out 30 miles (50 km) from the center of Bebinca’s circulation.  Winds to tropical storm force extended out 115 miles (185 km) from the center of Typhoon Bebinca.

Typhoon Bebinca will move through an environment favorable for intensification during the next 24 hours.  Bebinca will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the axis of an upper level ridge east of China.  The upper level winds are weak near the axis of the ridge and there will be little vertical wind shear.  Typhoon Bebinca will intensify during the next 24 hours.  Bebinca could intensify rapidly at times.

Typhoon Bebinca will move around the southern side of a high pressure system that extends from China to the Western North Pacific Ocean.  The high pressure system will steer Bebinca toward the west-northwest during the next 24 hours.  On its anticipated track, Typhoon Bebinca will approach the east coast of China near Shanghai.

Typhoon Bebinca will bring strong winds and heavy rain to the region of China near Shanghai.  Typhoon Bebinca will bring strong winds and heavy rain to Jiangsu and Zhejiang.  Heavy rain is likely to cause flash floods in some locations.

Typhoon Yagi Hits Hainan

Typhoon Yagi hit Hainan on Friday morning.  At 11:00 a.m. EDT on Friday the center of Typhoon Yagi was located at latitude 20.2°N and longitude 109.8°E which put the center about 25 miles (40 km) west of Haikou, China.  Yagi was moving toward the west-northwest at 13 m.p.h. (20 km/h).  The maximum sustained wind speed was 140 m.p.h. (220 km/h) and there were wind gusts to 165 m.p.h. (265 km/h).  The minimum surface pressure was 928 mb.

Typhoon Yagi brought strong winds and heavy rain to Hainan on Friday morning.  The core of Typhoon Yagi moved over the northeastern part of Hainan.  A small circular eye was present at the center of Yagi’s circulation.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.  The strongest winds moved over the northern coastal regions of Hainan.  Bands of showers and thunderstorms revolved around the core of Yagi’s circulation.  Storms dropped heavy rain on Hainan and southern China.

The formation of concentric eyewalls on Thursday caused the size of Typhoon Yagi’s circulation to increase.  Winds to typhoon force extended out 70 miles (110 km) from the center of Yagi’s circulation.  Winds to tropical storm force extended out 185 miles (300 km) from the center of Typhoon Yagi.

The Hurricane Intensity Index (HII) for Typhoon Yagi was 28.3.  The Hurricane Size Index (HII) was 24.9 and the Hurricane Wind Intensity Size Index (HWISI) was 53.2.  Typhoon Yagi was similar in size to Hurricane Jeanne when Jeanne hit southeast Florida in 2004.  Yagi was stronger than Jeanne was.

Typhoon Yagi will move through an environment that will be somewhat favorable for intensification during the next 12 hours.  The center of Yagi’s circulation will move over water where the Sea Surface Temperatures are near 30°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  However, Typhoon Yagi may not intensify during the next 12 hours because the core of Yagi’s circulation was somewhat disrupted as it moved across Hainan.

Typhoon Yagi will move around the southern part of a high pressure system over China.  The high pressure system will steer Yagi toward the west-northwest during the next 24 hours.  On its anticipated track, the center of Typhoon Yagi will reach northeastern Vietnam in 12 hours.  Typhoon Yagi could still be the equivalent of a major hurricane when it reaches VIetnam.

Typhoon Yagi will continue to produce strong winds and heavy rain in parts of Hainan during the  next few hours.  Yagi will be capable of causing major damage in Hainan.  Heavy rain is likely to cause floods in some locations. Typhoon Yagi will also produce strong winds and heavy rain in parts of southern China.  Yagi will produce strong winds and heavy rain in southwestern Guangdong and Guangxi.  Typhoon Yagi will bring strong winds and heavy rain to northeastern Vietnam during the weekend.  Yagi is likely to cause floods in northeastern Vietnam.  Typhoon Yagi could also cause a storm surge of up to 10 feet (3 meters) along the coast of northeastern Vietnam.

Typhoon Yagi Passes South of Hong Kong

Powerful Typhoon Yagi passed south of Hong Kong on Thursday.  At 5:00 p.m. EDT on Thursday the center of Typhoon Yagi was located at latitude 19.3°N and longitude 112.5°E which put the center about 230 miles (370 km) south-southwest of Hong Kong.  Yagi was moving toward the west at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 150 m.p.h. (240 km/h) and there were wind gusts to 185 m.p.h. (295 km/h).  The minimum surface pressure was 923 mb.

The inner end of a rainband wrapped around the original eye and eyewall at the core of Typhoon Yagi and concentric eyewalls formed.  The formation of concentric eyewalls ended the intensification of Typhoon Yagi, but Yagi was still the equivalent of a Category 4 hurricane on the Saffir-Simpson Scale.

A circular eye with a diameter of 23 miles (37 km) was at the center of Yagi’s circulation.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.  A second outer ring of thunderstorms surrounded the inner eyewall.  Bands of showers and thunderstorms were revolving around the core of Typhoon Yagi.  Storms near the core of Yagi generated upper level divergence that pumped mass away from the typhoon.

The formation of concentric eyewalls caused the size of Typhoon Yagi’s circulation to increase.  Winds to typhoon force extended out 90 miles (145 km) from the center of Yagi’s circulation.  Winds to tropical storm force extended out 205 miles (330 km) from the center of Typhoon Yagi.

The Hurricane Intensity Index (HII) for Typhoon Yagi was 31.6.  The Hurricane Size Index (HII) was 24.8 and the Hurricane Wind Intensity Size Index (HWISI) was 56.4.  Typhoon Yagi was similar in intensity to Hurricane Laura when Laura hit southwest Louisiana in 2020.  Yagi is bigger than Laura was.

Typhoon Yagi will move through an environment that will be favorable for intensification during the next 12 hours.  Yagi will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the middle of an upper level ridge over the South China Sea.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Even though Typhoon Yagi will move through a favorable environment, the concentric eyewalls may prevent Yagi from intensifying.  If the inner eyewalls weakens, then Typhoon Yagi could weaken as well.  If the inner eyewall remains intact, then Typhoon Yagi could intensify during the next few hours.

Typhoon Yagi will move around the southern part of a high pressure system over China.  The high pressure system will steer Yagi toward the west during the next 24 hours.  On its anticipated track, the center of Typhoon Yagi will reach northeastern Hainan in 12 hours.  Typhoon Yagi is likely to be the equivalent of a major hurricane when it reaches Hainan.

Typhoon Yagi will bring strong winds and heavy rain to Hainan.  Yagi will be capable of causing major damage in Hainan.  Heavy rain is likely to cause floods in some locations.  Typhoon Yagi could also cause a storm surge of up to 14 feet (4.3 meters) along the coast of northeastern Hainan.  Yagi will also bring strong winds and heavy rain to southwestern Guangdong and Guangxi.

 

Typhoon Yagi Rapidly Intensifies to Equivalent of a Major Hurricane

Typhoon Yagi rapidly intensified to the equivalent of a major hurricane over the South China Sea on Wednesday.  At 11:00 a.m. EDT on Wednesday the center of Typhoon Yagi was located at latitude 19.2°N and longitude 116.6°E which put the center about 275 miles (445 km) southeast of Hong Kong.  Yagi was moving toward the west at 6 m.p.h. (10 km/h).  The maximum sustained wind speed was 125 m.p.h. (200 km/h) and there were wind gusts to 155 m.p.h. (250 km/h).  The minimum surface pressure was 968 mb.

Typhoon Yagi rapidly intensified to the equivalent of a majoro hurricane on Wednesday.  A circular eye was visible at the center of Yagi’s circulation.  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 Typhoon Yagi.  Storms near the core generated upper level divergence that pumped large amounts of mass away from the typhoon.  The removal of large amounts of mass caused the surface pressure to decrease rapidly.

The circulation around Typhoon Yagi increased in size as Yagi intensified rapidly.  Winds to typhoon force extended out 60 miles (95 km) from the center of Yagi’s circulation.  Winds to tropical storm force extended out 140 miles (220 km) from the center of Typhoon Yagi.

The Hurricane Intensity Index (HII) for Typhoon Yagi was 23.6.  The Hurricane Size Index (HSI) was 16.2 and the Hurricane Wind Intensity Size Index (HWISI) was 39.8.  Typhoon Yagi was similar in intensity to Hurricane Dennis when Dennis hit Florida in 2005.  Yagi is larger than Dennis was.

Typhoon Yagi will move through an environment that will be very favorable for intensification during the next 24 hours.  Yagi will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the middle of an upper level ridge over the South China Sea. The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Typhoon Yagi will intensify during the next 24 hours.  Yagi could continue to intensify rapidly during the next few hours.  If the inner end of rainband wraps around the eye and eyewall in the core of Yagi’s circulation, then an eyewall replacement cycle could cause Typhoon Yagi to weaken.

Typhoon Yagi will move around the southern part of a high pressure system over China.  The high pressure system will steer Yagi toward the west-northwest during the next 24 hours. On its anticipated track, the center of Typhoon Yagi will be south of Hong Kong in 24 hours.  Yagi will approach Hainan and the coast of southern China in 36 hours.  Typhoon Yagi is likely to be the equivalent of a major hurricane when it approaches Hainan and the coast of southern China.

Typhoon Yagi will bring strong winds and heavy rain to southern China later this week.  Yagi will bring strong winds and heavy rain to Guangdong, Guangxi and Hainan.  Heavy rain is likely to cause floods in some locations.

 

Yagi Strengthens to a Typhoon Southeast of Hong Kong

Former Tropical Storm Yagi strengthened to a typhoon southeast of Hong Kong on Tuesday evening.  At 11:00 p.m. EDT on Tuesday the center of Typhoon Yagi was located at latitude 19.1°N and longitude 117.5°E which put the center about 315 miles (510 km) southeast of Hong Kong.  Yagi was moving toward the west-northwest at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 100 m.p.h. (160 km/h).  The minimum surface pressure was 977 mb.

Former Tropical Storm Yagi intensified rapidly to a typhoon after it moved over the South China Sea.  A circular eye formed at the center of Yagi’s circulation.  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 Typhoon Yagi.  Storms near the core generated upper level divergence that pumped mass away from the typhoon.  The removal of mass caused the surface pressure to decrease.

The circulation around Typhoon Yagi was symmetrical.  Winds to typhoon force extended out 35 miles (55 km) from the center of Yagi’s circulation.  Winds to tropical storm force extended out 110 miles (185 km) from the center of Typhoon Yagi.

Typhoon Yagi will move through an environment that will be very favorable for intensification during the next 24 hours.  Yagi will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the middle of an upper level ridge over the South China Sea. The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Typhoon Yagi will intensify during then next 24 hours.  Yagi could intensify rapidly to the equivalent of a major hurricane.

Typhoon Yagi will move around the southern part of a high pressure system over China.  The high pressure system will steer Yagi toward the west-northwest during the next 24 hours.  On its anticipated track, the center of Typhoon Yagi will be south of Hong Kong in 36 hours.  Yagi will approach Hainan and the coast of southern China in 48 hours.  Typhoon Yagi could be the equivalent of a major hurricane when it approaches Hainan and the coast of southern China.

 

 

Tropical Storm Gaemi Brings Wind and Rain to Eastern China

Tropical Storm Gaemi brought wind and rain to parts of eastern China on Thursday.  At 11:00 a.m. EDT on Thursday the center of Tropical Storm Gaemi was located at latitude 25.9°N and longitude 119.1°E which put the center about 25 miles (40 km) west of Fuzhou, China.  Gaemi was moving toward the northwest at 6 m.p.h. (10 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 973 mb.

Former Typhoon Gaemi weakened to a tropical storm on Thursday before it made landfall on the east coast of China.  The center of Gaemi’s circulation made landfall southeast of Fuzhou near Fuqing.  Showers and thunderstorms in bands in the eastern and southern parts of Tropical Storm Gaemi were dropping heavy rain.  The bands in the northern and western parts of Gaemi’s circulation consisted primarily of showers and lower clouds.

The circulation around Tropical Storm Gaemi was large.  Winds to tropical storm force extended out 220 miles (350 km) from the center of Gaemi’s circulation.  The strongest winds were occurring in bands that were still over water in the eastern and southern parts of Tropical Storm Gaemi.

Tropical Storm Gaemi will move toward the northwest during the next 24 hours.  Gaemi will weaken as it moves farther inland over eastern China.  Tropical Storm Gaemi will drop heavy rain over parts of Fujian, Jiangxi and Zhejiang.  Heavy rain is likely to cause floods in some locations.

Typhoon Gaemi Batters Taiwan

Typhoon Gaemi battered Taiwan on Wednesday.  At 11:00 a.m. EDT on Wednesday the center of Typhoon Gaemi was located at latitude 24.0°N and longitude 121.4°E which put the center about 100 miles (160 km) south of Taipei, Taiwan.  Gaemi was moving toward the northwest at 8 m.p.h. (13 km/h).  The maximum sustained wind speed was 125 m.p.h. (200 km/h) and there were wind gusts to 155 m.p.h. (250 km/h).  The minimum surface pressure was 928 mb.

The inner end of a rainband wrapped around the existing eye and eyewall of Typhoon Gaemi as it approached the east coast of Taiwan.  Concentric eyewalls formed in the core of Gaemi’s circulation.  The diameter of the inner eye was 7 miles (11 km).  The inner 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 Typhoon Gaemi.

The inner eye of Typhoon Gaemi began to make a counterclockwise loop inside the outer eyewall as Gaemi neared the east coast of Taiwan.  Mountains in Taiwan also deflected winds blowing around the western side of Typhoon Gaemi.  The deflection of the winds by the mountains also contributed to the counterclockwise loop of the inner eye.  The inner eye made landfall near Yilan City after it completed the counterclockwise loop.

The circulation around Typhoon Gaemi was large.  Winds to typhoon force extended out 105 miles (165 km) from the center of Gaemi’s circulation.  Winds to tropical storm force extended out 315 miles (510 km) from the center of Typhoon Gaemi.

Typhoon Gaemi was the equivalent of a major hurricane at the time of landfall.  The Hurricane Intensity Index (HII) was 23.6.  The Hurricane Size Index (HSI) was 35.2 and the Hurricane Wind Intensity Size Index (HWISI) was 58.8.  Typhoon Gaemi was as strong as Hurricane Katrina was when Katrina made landfall on the coast of the Gulf of Mexico in 2005.  Gaemi was larger than Katrina was when Katrina made landfall.

Typhoon Gamei was producing strong winds in Taiwan.  Gaemi was also dropping very heavy rain over parts of Taiwan.  Prolonged heavy rain is likely to cause flash floods in many locations.  Typhoon Gaemi was also causing a storm surge of up to 13 feet (4 meters) along the coast of northern Taiwan where the wind was blowing water toward the coast.

Typhoon Gaemi will move toward the northwest during the next 24 hours.  Gaemi will continue to produce strong winds and heavy rain in Taiwan for another 12 to 24 hours.  The center of Typhoon Gaemi will move over the Taiwan Strait in a few hours.  Gaemi will make another landfall on the east coast of China in about 18 hours.

Typhoon Gaemi Strengthens to Equivalent of a Major Hurricane

Typhoon Gaemi strengthened to the equivalent of a major hurricane east of Taiwan on Tuesday.  At 5:00 p.m. EDT on Tuesday the center of Typhoon Gaemi was located at latitude 23.1°N and longitude 123.2°E which put the center about 200 miles (325 km) southeast of Taipei, Taiwan.  Gaemi was moving toward the northwest at 15 m.p.h. (24 km/h).  The maximum sustained wind speed was 140 m.p.h. (225 km/h) and there were wind gusts to 165 m.p.h. (265 km/h).  The minimum surface pressure was 948 mb.

Typhoon Gaemi rapidly intensified to the equivalent of a Category 4 hurricane on the Saffir-Simpson Scale east of Taiwan on Tuesday.  A small circular eye with a diameter of 6 miles (10 km) formed at the center of Gaemi’s circulation.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storm.  Bands of showers and thunderstorms were revolving around the core of Typhoon Gaemi.  Storms near the core generated strong upper level divergence that pumped mass away from the typhoon.  The removal of large amounts of mass caused the surface pressure to decrease rapidly.

The circulation around Typhoon Gaemi was large.  Winds to typhoon force extended out 100 miles (160 km) from the center of Gaemi’s circulation.  Winds to tropical storm force extended out 345 miles (555 km) from the center of Typhoon Gaemi.

The Hurricane Intensity Index (HII) for Typhoon Gaemi was 28.3.  The Hurricane Size Index (HSI) was 31.0 and the Hurricane Wind Intensity Size Index (HWISI) was 59.3.  Typhoon Gaemi was similar in size to Hurricane Wilma when Wilma hit South Florida in 2005.  Gaemi is stronger than Wilma was when it hit South Florida.

Typhoon Gaemi will move through an environment favorable for intensification during the next 12 hours.  Gaemi will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the axis of an upper level ridge over the Western North Pacific Ocean.  The upper level winds are weak near the axis of the ridge and there will be little vertical wind shear.  Typhoon Gaemi could continue to intensify during the next 12 hours.

Typhoon Gaemi will move around the western part of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Typhoon Gaemi toward the northwest during the next 24 hours.  On its anticipated track, Typhoon Gaemi will approach the coast of northeastern Taiwan in 12 hours.

Typhoon Gaemi will bring very strong winds and torrential rain to Taiwan.  Gaemi will be capable of causing extensive severe damage.  Heavy rain is likely to cause widespread flash floods.  Typhoon Gaemi will also be capable of causing a storm surge of up to 13 feet (4 meters) along the east coast of Taiwan.

Typhoon Gaemi will also bring strong winds and heavy rain to the southern Ryukyu Islands.  The strongest part Gaemi’s circulation will pass southwest of the Ryukyu Islands, but the typhoon is likely to some wind damage.  Heavy rain could cause flash floods in some locations.

Typhoon Gaemi will move toward the east coast of China after is crosses northern Taiwan.  Gaemi could approach the coast of China in less than 36 hours.  Typhoon Gaemi will weaken when it moves over Taiwan, but Gaemi could still be a typhoon when it reaches China.

Elsewhere, former Tropical Storm Prapiroon weakened to a tropical depression over northern Vietnam.  At 11:00 a.m. EDT on Tuesday the center of Tropical Depression Prapiroon was located at latitude 22.0°N and longitude 107.0°E which put the center about 25 miles (40 km) northeast of Lang Son, Vietnam.  Prapiroon was moving toward the north-northwest at 5 m.p.h. (8 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 994 mb.

Gaemi Intensifies to Typhoon Southeast of Taiwan

Former Tropical Storm Gaemi intensified to a typhoon over the Western North Pacific Ocean southeast of Taiwan on Monday.  At 5:00 p.m. EDT on Monday the center of Typhoo Gaemi was located at latitude 18.8°N and longitude 124.7°E which put the center about 405 miles (655 km) southeast of Hualien, Taiwan.  Gaemi was moving toward the west at 6 m.p.h. (10 km/h).  The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 100 m.p.h. (160 km/h).  The minimum surface pressure was 977 mb.

Former Tropical Storm Gaemi exhibited more organization on Monday as it strengthened to a typhoon.  The inner end of a rainband wrapped around the center of Gaemi’s circulation.  An eye appeared to be forming at the center of Typhoon Gaemi.  A ring of showers and thunderstorms surrounded the developing eye.  The ring was thickest in the southeastern side of the eye and thinnest in the northwestern side.  Other bands of thunderstorms were occurring southern and eastern parts of Gaemi’s circulation.  Bands in the northern and western parts of Typhoon Gaemi consisted primarily of showers and lower clouds.

Winds to typhoon force extended out 45 miles (75 km) from the center of Typhoon Gaemi.  Winds to tropical storm force extended out 155 miles (250 km) from the center of Gaemi’s circulation.

Typhoon Gaemi will move through an environment favorable for intensification during the next 24 hours.  Gaemi will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the axis of an upper level ridge over the Western North Pacific Ocean.  The upper level winds are weak near the axis of the ridge and there will be little vertical wind shear.  Typhoon Gaemi will continue to intensify during the next 24 hours.

Typhoon Gaemi will move around the western part of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Typhoon Gaemi toward the northwest during the next 24 hours.  On its anticipated track, Typhoon Gaemi will approach the east coast of Taiwan in 36 hours.

Typhoon Gaemi will bring strong winds and heavy rain to Taiwan during the middle of the week.  Heavy rain is likely to cause flash floods.

Elsewhere, Tropical Storm Prapiroon brought wind and rain to northern Vietnam.  At 5:00 p.m. EDT on Monday the center of Tropical Storm Prapiroon was located at latitude 21.2°N and longitude 107.9°E which put the center about 40 miles (65 km) east of Cam Pha, Vietnam.  Prapiroon was moving toward the northwest 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 985 mb.

Tropical Storm Prapiroon Brings Wind and Rain to Hainan

Tropical Storm Prapiroon brought wind and rain to Hainan on Sunday.  At 5:00 p.m. EDT on Sunday the center of Tropical Storm Prapiroon was located at latitude 19.1°N and longitude 109.9°E which put the center about 65 miles (105 km) south-southwest of Haikou, China.  Prapiroon was moving toward the northwest at 13 m.p.h. (21 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 992 mb.

Tropical Storm Prapiroon intensified on Sunday before the center moved over Hainan.  Microwave satellite images indicated that an eye was in the process of forming at the center of Prapiroon’s circulation as the tropical storm made landfall in Hainan.  The formative eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the center of Tropical Storm Prapiroon.

Winds to tropical storm force extended out 70 miles (110 km) from the center of Tropical Storm Prapiroon.

The center of Tropical Storm Prapiroon made landfall on the south coast of Hainan near Lingshui.  The core of Prapiroon’s circulation moved across the center of Hainan.  Storms near the center of Tropical Storm Prapiroon brought heavy rain and strong winds to much of Hainan.  Bands in the northern part of Hainan’s circulation were also bringing gusty winds and heavy rain to parts of southern China.

Tropical Storm Prapiroon will move around the southern side of a high pressure system over southern China.  The high pressure system will steer Prapiroon toward the northwest during the next 24 hours.  On its anticipated track Tropical Storm Prapiroon will move over the Gulf of Tonkin on Monday.  The center of Prapiroon’s circulation could approach the southern coast of China in 24 hours.

Tropical Storm Prapiroon will continue to cause strong winds and locally heavy rain in Hainan during the next few hours.  Heavy rain could cause flash floods in some locations.  Prapiroon will also bring gusty winds and heavy rain to parts of southern China and northeastern Vietnam.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Gaemi strengthened east of Luzon.  At 5:00 p.m. EDT on Sunday the center of Tropical Storm Gaemi was located at latitude 17.2°N and longitude 125.7°E which put the center about 525 miles (845 km) south of Ishigakijima, Japan.  Gaemi was moving toward the north-northwest at 3 m.p.h.
