Typhoon Haikui Hits Taiwan

Typhoon Haikui hit Taiwan on Sunday morning. At 5:00 a.m. EDT on Sunday the center of Typhoon Haikui was located at latitude 22.9°N and longitude 121.1°E which put it about 20 miles (30 km) northeast of Taitung, Taiwan. Haikui was moving toward the west at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 120 m.p.h. (195 km/h) and there were wind gusts to 150 m.p.h. (240 km/h). The minimum surface pressure was 947 mb.

The center of Typhoon Haikui made landfall on the southeast coast of Taiwan just to the northeast of Taitung on Sunday morning. Haikui intensified to the equivalent of a major hurricane as it approached the coast of Taiwan. The Hurricane Intensity Index (HII) for Typhoon Haikui was 22.1. The Hurricane Size Index (HSI) was 13.0 and the Hurricane Wind Intensity Size Index (HWISI) was 35.1. Typhoon Haikui was similar in size and intensity to Hurricane Dennis when Dennis hit Northwest Florida in 2005.

Typhoon Haikui brought strong, gusty winds and heavy rain to Taiwan. Winds to typhoon force extended out 40 miles (65 km) from the center of Haikui’s circulation. Winds to tropical storm force extended out 115 miles (185 km) from the center of circulation.

The center of Typhoon Haikui will move across southern Taiwan during the next few hours. Haikui’will produce strong, gusty winds in much of Taiwan. Typhoon Haikui is capable of causing regional major damage. Widespread outages of electricity are likely. Heavy rains will cause flash floods, especially near mountains.

The center of Typhoon Haikui will be near Kaohsiung in a few hours. Haikui will weaken as it moves across southern Taiwan. Mountains in Taiwan could will disrupt the circulation in the lower levels of Typhoon Haikui. The circulation in the middle and upper troposphere will remain move relatively intact. Haikui will move over the South China Sea later on Sunday. Typhoon Haikui could approach the coast of China near Shantou in less than 36 hours.

Typhoon Haikui Nears Taiwan

Typhoon Haikui neared Taiwan on Saturday. At 5:00 p.m. EDT on Saturday the center of Typhoon Haikui was located at latitude 22.6°N and longitude 122.7°E which put it about 100 miles (160 km) east-southeast of Taitung, Taiwan. Haikui was moving toward the west at 13 m.p.h. (21 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 958 mb.

Typhoon Haikui intensified as it neared Taiwan on Saturday. A small circular eye was at the center of Haikui’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 Haikui. Storms near the core generated upper level divergence that pumped mass away from the typhoon.

The Taiwan Central Weather Bureau’s radar images indicated that Typhoon Haikui was very symmetrical. Winds to typhoon force extended out 35 miles (55 km) from the center of Haikui’s circulation. Winds to tropical storm force extended out 115 miles (185 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Haikui was 17.8. The Hurricane Size Index (HSI) was 9.7 and the Hurricane Wind Intensity Size Index (HWISI) was 27.5. Typhoon Haikui was similar in size and intensity to Hurricane Zeta when Zeta hit Louisiana in 2020.

Typhoon Haikui will move through an environment favorable for intensification during the next few hours. Haikui will move over water where the Sea Surface Temperatures are near 30°C. It will move under the southern part of an upper level ridge centered north of Taiwan. The ridge will produce easterly winds that will blow toward the top of Haikui’s circulation. The winds in the lower levels of the atmosphere will also blow from the east. So, there will be little vertical wind shear. Typhoon Haikui is likely to continue to intensify during the next few hours until it makes landfall on Taiwan.

Typhoon Haikui will move around the southern part of a high pressure system over the Western North Pacific Ocean. The high pressure system will steer Haikui toward the west- northwest during the next 24 hours. On its anticipated track, the center of Typhoon Haikui will move landfall on the coast of southeast Taiwan near Taitung in nine hours.

Typhoon Haikui will bring strong winds and heavy rain to Taiwan. Haikui will be capable of causing regional serious damage. The heaviest rain will fall on the eastern sides of mountains where the wind will push air up the slopes. Heavy rain is likely to cause flash floods.

Elsewhere over the Western North Pacific Ocean, former Typhoon Saola weakened to a tropical storm along the coast of southern China and former Tropical Storm Kirogi weakened to a tropical depression south of Japan. At 5:00 p.m. EDT on Saturday the center of Tropical Storm Saola was located at latitude 21.6°N and longitude 109.5°E which put it about 35 miles (55 km) east-northeast of Beihai, China. Saola was moving toward the west-southwest at 7 m.p.h. (11 km/h). The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h). The minimum surface pressure was 991 mb.

At 5:00 p.m. EDT on Saturday the center of Tropical Depression Kirogi was located at latitude 29.6°N and longitude 142.0°E which put it about 370 miles (595 km) south-southeast of Tokyo, Japan. Kirogi was moving toward the northwest at 22 m.p.h. (35 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 1000 mb.

Typhoon Saola Brings Wind and Rain to Hong Kong

Typhoon Saloa brought strong winds and heavy rain to Hong Kong on Friday morning. At 11:00 p.m. EDT on Friday the center of Typhoon Saola was located at latitude 22.1°N and longitude 114.0°E which put it about 20 miles (30 km) southeast of Hong Kong. Saola was moving toward the west at 11 m.p.h. (17 km/h). The maximum sustained wind speed was 130 m.p.h. (210 km/h) and there were wind gusts to 160 m.p.h. (260 km/h). The minimum surface pressure was 938 mb.

Powerful Typhoon Saloa brought strong winds and heavy rain to Hong Kong on Friday morning. The Hong Kong International Airport (VHHH) reported a sustained wind speed of 63 m.p.h. (102 km/h) and a wind gust of 85 m.p.h. (139 km/h). The strongest winds in Typhoon Saola were occurring in the South China Sea just to the south of Hong Kong.

Typhoon Saloa started to weaken just as it approached Hong Kong. Northerly winds blowing around the western side of Saola’s circulation pulled drier air over China into the typhoon. The drier air caused Typhoon Saola to start to weaken. Even though Saola started to weaken, it remained a powerful typhoon. Winds to typhoon force extended out 50 miles (80 km) from the center of Typhoon Saola. Winds to tropical storm force extended out 115 miles (185 km) from the center of circulation.

The Hurricane Intensity Index (HII) for Typhoon Saola was 25.1. The Hurricane Size Index (HSI) was 16.5 and the Hurricane Wind Intensity Size Index (HWISI) was 41.6. Typhoon Saola was capable of causing region major damage.

Typhoon Saola will move south of a high pressure system over China. The high pressure system will steer Saola toward the west-southwest during the next 24 hours. On its anticipated track, Typhoon Saola will move along the coast of Guangdong province.

Typhoon Saola will continue to produce strong winds and heavy rain in Hong Kong during the next few hours. The strong winds could cause widespread outages of electricity. The heavy rain is likely to cause flash floods in some locations. Typhoon Saloa will weaken as it pulls in more drier air. Even though Saola will weaken, strong winds and heavy rain will spread along the coastal part of Guangdong province west of Hong Kong as Typhoon Saola moves toward the west-southwest during the next 24 hours. Strong winds and heavy rain could reach Macau in a few hours.

Elsewhere over the Western North Pacific Ocean, Typhoon Haikui was moving toward Taiwan and Tropical Storm Kirogi weakened east of Iwo To. At 11:00 a.m. EDT on Friday the center of Typhoon Haikui was located at latitude 22.1°N and longitude 127.3°E which put it about 415 miles (670 km) east of Taiwan. Haikui was moving toward the west at 8 m.p.h. (13 km/h). The maximum sustained wind speed was 85 m.p.h. (135 km/h) and there were wind gusts to 105 m.p.h. (165 km/h). The minimum surface pressure was 971 mb. Typhoon Haikui could approach Taiwan in 36 hours.

At 11:00 a.m. EDT on Friday the center of Tropical Storm Kirogi was located at latitude 23.9°N and longitude 149.0°E which put it about 475 miles (765 km) east of Iwo To. Kirogi was moving toward the northwest at 20 m.p.h. (32 km/h). The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h). The minimum surface pressure was 999 mb.

Typhoon Saola Nears Hong Kong

Powerful Typhoon Saola neared Hong Kong on Thursday night. At 11:00 p.m. EDT on Thursday the center of Typhoon Saola was located at latitude 21.9°N and longitude 115.9°E which put it about 140 miles (225 km) east-southeast of Hong Kong. Saola was moving toward the west-northwest at 6 m.p.h. (10 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 935 mb.

Powerful Typhoon Saola moved steadily closer to Hong Kong on Thursday night. A circular eye with a diameter of 25 miles (40 km) was at the center of Saola’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 Saola’s circulation. Storms near the core generated strong upper level divergence that pumped large quantities of mass away from the typhoon.

The size of the circulation around Typhoon Saola remained relatively constant on Thursday. Winds to typhoon force extended out 50 miles (80 km) from the center of Saola’s circulation. Winds to tropical storm force extended out 115 miles (185 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Saola was 28.3. The Hurricane Size Index (HSI) was 17.2 and the Hurricane Wind Intensity Size Index (HWISI) was 45.5. Typhoon Saola was similar in size and intensity to Hurricane Ida when Ida hit Louisiana in 2021.

Typhoon Saola will move through an environment that will become less favorable for intensification during the next 24 hours. Saola will move over water where the Sea Surface Temperatures are near 30°C. It will move through a region where the upper level ridge winds are weak and there will be little vertical wind shear. However, the circulation around Typhoon Saola could pull in some drier air over China when Saola gets closer to Hong Kong. In addition, if the inner end of a rainband wraps around the existing eye and eyewall, then concentric eyewalls could form. Typhoon Saola is likely to weaken during the next 24 hours, when drier air gets pulled into its circulation.

Typhoon Saola will move around the southern side of a high pressure system over China. The high pressure system will steer Saola toward the west-northwest during the next 24 hours. On its anticipated track, the center of Typhoon Saola will be near Hong Kong in 12 hours.

Typhoon Saola could be the equivalent of a major hurricane when it reaches Hong Kong. Saola will bring strong, gusty winds and locally heavy rain to the area around Hong Kong. Widespread electricity outages are likely. Heavy rain will cause flash floods in some locations. There will also be a significant storm surge where the wind blows the water toward the coast.

Elsewhere over the Western North Pacific Ocean, Typhoon Haikui was moving toward Taiwan and Tropical Storm Kirogi was spinning east-southeast of Iwo To. At 11:00 p.m. EDT on Thursday the center of Typhoon Haikui was located at latitude 22.1°N and longitude 129.1°E which put it about 535 miles (865 km) east of Taiwan. Haikui was moving toward the west at 8 m.p.h. (13 km/h). The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 95 m.p.h. (150 km/h). The minimum surface pressure was 975 mb.

At 11:00 p.m. EDT on Thursday the center of Tropical Storm Kirogi was located at latitude 21.0°N and longitude 150.9°E which put it about 715 miles (1155 km) east-southeast of Iwo To. Kirogi was moving toward the northwest at 18 m.p.h. (30 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.

Typhoon Saola Moves Toward Hong Kong

Powerful Typhoon Saola moved across the South China Sea toward Hong Kong on Wednesday night. At 11:00 p.m. EDT on Wednesday the center of Typhoon Saola was located at latitude 21.1°N and longitude 117.8°E which put it about 265 miles (430 km) east-southeast of Hong Kong. Saola was moving toward the west at 8 m.p.h. (13 km/h). The maximum sustained wind speed was 155 m.p.h. (250 km/h) and there were wind gusts to 190 m.p.h. (305 km/h). The minimum surface pressure was 922 mb.

Typhoon Saola maintained its intensity near the threshold of the equivalent of a Category 5 hurricane on the Saffir-Simpson Scale in Tuesday. A circular eye with a diameter of 18 miles (30 km) was at the center of Saola’ circulation. The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms. Numerous bands of showers and thunderstorms were revolving around the core of Saola’s circulation. Storms near the core generated strong upper level divergence that pumped large quantities of mass away from the typhoon.

The size of the circulation around Typhoon Saola remained relatively constant on Wednesday. Winds to typhoon force extended out 45 miles (75 km) from the center of Saola’s circulation. Winds to tropical storm force extended out 115 miles (185 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Saola was 33.3. The Hurricane Size Index (HSI) was 15.9 and the Hurricane Wind Intensity Size Index (HWISI) was 49.2. Typhoon Saola was similar in size and intensity to Hurricane Ian when Ian hit southwest Florida in 2022.

Typhoon Saola will move through an environment favorable for a powerful typhoon during the next 24 hours. Saola will move over water where the Sea Surface Temperatures are near 30°C. It will move through a region where the upper level ridge winds are weak and there will be little vertical wind shear. Typhoon Saola has been in equilibrium with its environment and Saola could maintain much of its intensity during the next 24 hours unless concentric eyewalls form. If concentric eyewalls form, then an eyewall replacement cycle would cause Saola to weaken.

Typhoon Saola will move around the southern side of a high pressure system over China. The high pressure system will steer Saola toward the west-northwest during the next 24 hours. On its anticipated track, Typhoon Saola will closer to Hong Kong. The center of Saola could be near Hong Kong in 36 hours.

Haikui 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 989 mb.

At 11:00 p.m. EDT on Wednesday the center of Tropical Storm Kirogi was located at latitude 15.9°N and longitude 154.2°E which put it about 650 miles (1050 km) east of Guam. Kirogi was moving toward the north at 14 m.p.h. (22 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 996 mb.

Powerful Typhoon Saola Moves Between Taiwan and Luzon

Powerful Typhoon Saola moved between Taiwan and Luzon on Tuesday night. At 11:00 p.m. EDT on Tuesday the center of Typhoon Saola was located at latitude 20.3°N and longitude 120.7°E which put it about 160 miles (260 km) south-southeast of Kaohsiung, Taiwan. Saola was moving toward the west-northwest at 9 m.p.h. (15 km/h). The maximum sustained wind speed was 155 m.p.h. (250 km/h) and there were wind gusts to 190 m.p.h. (305 km/h). The minimum surface pressure was 922 mb.

Typhoon Saola intensified to the threshold of the equivalent of a Category 5 hurricane on the Saffir-Simpson Scale in Tuesday. A circular eye with a diameter of 15 miles (24 km) was at the center of Saola’ 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 Saola’s circulation. Storms near the core generated strong upper level divergence that pumped large quantities of mass away from the typhoon.

The size of the circulation around Typhoon Saola increased when Saola intensified on Tuesday. Winds to typhoon force extended out 45 miles (75 km) from the center of Saola’s circulation. Winds to tropical storm force extended out 115 miles (185 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Saola was 33.3. The Hurricane Size Index (HSI) was 16.2 and the Hurricane Wind Intensity Size Index (HWISI) was 49.5. Typhoon Saola was similar in size and intensity to Hurricane Ian when Ian hit southwest Florida in 2022.

Typhoon Saola will move through an environment favorable for a powerful typhoon during the next 24 hours. Saola will move over water where the Sea Surface Temperatures are near 29°C. It will move through a region where the upper level ridge winds are weak and there will be little vertical wind shear. Typhoon Saola could maintain much of its intensity during the next 24 hours unless concentric eyewalls for again. If concentric eyewalls form again, then an eyewall replacement cycle would cause Saola to weaken.

Typhoon Saola will move around the southern side of a high pressure system over China. The high pressure system will steer Saola toward the west-northwest during the next 24 hours. On its anticipated track, Typhoon Saola will move over the South China Sea. Saola could be near Hong Kong later this week.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Haikui was southwest of Iwo To. At 11:00 p.m. EDT on Tuesday the center of Tropical Storm Haikui was located at latitude 20.2°N and longitude 135.7°E which put it about 457 miles (755 km) southwest of Iwo To. Haikui 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 990 mb.

Tropical Storm Khanun Spins East of the Philippines

Tropical Khanun was spinning east of the Philippines on Friday. At 5:00 p.m. EDT on Friday the center of Tropical Storm Khanun was located at latitude 16.0°N and longitude 134.4°E which put it about 870 miles (1405 km) south-southeast of Okinawa. Khanun was moving toward the northwest at 13 m.p.h. (20 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 996 mb.

Tropical Storm Khanun gradually became more organized as it spun east of the Philippines on Friday. The distribution of thunderstorms in Khanun’s circulation was asymmetrical. Many of the thunderstorms were occurring in bands in the southern half of Tropical Storm Khanun. The strongest winds were occurring in those rainbands. Winds to tropical storm force extended out 200 miles (320 km) in the southern side of Khanun. Bands in the northern half of Khanun consisted primarily of showers and lower clouds. The winds in the northern side of Tropical Storm Khanun were blowing at less than tropical storm force. Storms near the center of Khanun’s circulation generated upper level divergence that pumped mass away to the south of the tropical storm.

Tropical Storm Khanun will move through an environment that will be somewhat favorable for intensification during the next 24 hours. Khanun will move over water where the Sea Surface Temperatures are near 30˚C. It will move under the eastern side of an upper level ridge over eastern China. The ridge will produce northerly winds that will blow toward the top of Khanun’s circulation. Those winds will cause moderate vertical wind shear. The wind shear will inhibit intensification. Tropical Storm Khanun is likely to intensify gradually during the next 24 hours.

Tropical Storm Khanun will move around the southwestern side of a subtropical high pressure system over the Western North Pacific Ocean. The high pressure system will steer Khanun toward the northwest during the next 24 hours. On its anticipated track, Tropical Storm Khanun will move toward the Ryukyu Islands. Khanun could approach Okinawa in less than 72 hours.

Elsewhere, Tropical Storm Doksuri weakened as it moved farther inland over eastern China. Doksuri was still dropping heavy rain over parts of eastern China. At 2:00 p.m. EDT on Thursday the center of Tropical Storm Doksuri was located at latitude 28.9°N and longitude 117.0°E which put it about 25 miles (40 km) south of Jingdezhen, China. Doksuri was moving toward the north-northwest at 18 m.p.h. (30 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 996 mb.

Typhoon Doksuri Hits Eastern China

Typhoon Doksuri hit eastern China on Thursday night. At 11:00 p.m. EDT on Thursday the center of Typhoon Doksuri was located at latitude 24.8°N and longitude 118.5°E which put it about 35 miles (55 km) northeast of Xiamen, China. Doksuri was moving toward the north-northwest at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 110 m.p.h. (175 km/h) and there were wind gusts to 130 m.p.h. (210 km/h). The minimum surface pressure was 940 mb.

The center of Typhoon Doksuri made landfall on the east coast of China between Xiamen and Quanzhou on Thursday night. Doksuri was bringing strong winds and heavy rain to Fujian. Winds to typhoon force extended out 40 miles (65 km) from the center of Doksuri’s circulation. Winds to tropical storm force extended out 140 miles (225 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Doksuri was 19.2. The Hurricane Size Index (HSI) was 13.6 and the Hurricane Wind Intensity Size Index (HWISI) was 32.8. Typhoon Doksuri was similar in size and intensity to Hurricane Sally when Sally hit Alabama in 2020.

Typhoon Doksuri will continue to move toward the north-northwest during the next 36 hours. On its anticipated track, Typhoon Doksuri will move inland over eastern China. Doksuri will weaken as it moves inland. The core of Typhoon Doksuri will bring strong winds to Fujian. Doksuri will also drop heavy rain over parts of Fujian. Heavy rain could cause flash floods in some locations. Doksuri will bring gusty winds and locally heavy rain to parts of Zhejiang and Jiangxi.

Elsewhere over the Western North Pacific Ocean, former Tropical Depression 06W strengthened to Tropical Storm Khanun east of the Philippines. At 11:00 p.m. EDT on Thursday the center of Tropical Storm Khanun was located at latitude 13.4°N and longitude 135.7°E which put it about 1060 miles (1710 km) south-southeast of Okinawa. Khanun was moving toward the west at 10 m.p.h. (16 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. Tropical Storm Khanun is forecast to move toward the Ryukyu Islands and to strengthen to a typhoon.

Typhoon Doksuri Moves over Taiwan Strait

Typhoon Doksuri moved over the Taiwan Strait on Thursday morning. At 11:00 a.m. EDT on Thursday the center of Typhoon Doksuri was located at latitude 22.3°N and longitude 119.0°E which put it about 170 miles (275 km) south-southeast of Xiamen China. Doksuri was moving toward the north-northwest at 8 m.p.h. (13 km/h). The maximum sustained wind speed was 120 m.p.h. (195 km/h) and there were wind gusts to 150 m.p.h. (240 km/h). The minimum surface pressure was 943 mb.

Radar images from Taiwan’s Central Weather Bureau showed clearly that there were concentric eyewalls at the core of Typhoon Doksuri. A small circular eye with a diameter of 7 miles (11 km) was at the center of Doksuri’s circulation. The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms. The inner eyewall was surrounded by a relatively clear area, sometimes called a moat. A much larger, outer eyewall with a diameter of 60 miles (95 km) surrounded the inner eyewall and the moat. Bands of showers and thunderstorms were revolving around the concentric eyewalls. Storms in the concentric eyewalls generated upper level divergence that pumped mass away from the typhoon.

Both the inner and outer eyewalls of Typhoon Doksuri were over the Taiwan Strait. Mountains in Taiwan were deflecting some of the wind circulating around the eastern side of Doksuri, and the core of circulation tightened up a little. Winds to typhoon force extended out 45 miles (75 km) from the center of Doksuri’s circulation. Winds to tropical storm force extended out 160 miles (260 km) from the center. The Hurricane Intensity Index (HII) for Typhoon Doksuri was 22.1. The Hurricane Size Index (HSI) was 17.1 and the Hurricane Wind Intensity Size Index (HWISI) was 39.2. Typhoon Doksuri was bigger and stronger than Hurricane Delta when Delta hit Louisiana in 2020. Doksuri was capable of causing regional severe damage.

Typhoon Doksuri will move through an environment very favorable for intensification during the next 12 hours. Doksuri will move over water where the Sea Surface Temperatures are near 31˚C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. However, the concentric eyewalls at the center of Typhoon Doksuri will inhibit intensification. Doksuri could weaken if the inner eye and eyewall dissipate. If the inner eye and eyewall remain intact, then Typhoon Doksuri could strengthen during the next 12 hours.

Typhoon Doksuri will move around the western side of a subtropical high pressure system over the Western North Pacific Ocean. The high pressure system will steer Doksuri toward the north-northwest during the next 24 hours. On its anticipated track, Typhoon Doksuri will approach the east coast of China near Xiamen in 24 hours. Doksuri will bring strong winds and heavy rain to Fujian. Heavy rain could cause flash floods in some locations. Typhoon Doksuri could also cause a storm surge of up to 13 feet (4 meters) along the coast of Fujian.

Bands in the eastern side of Typhoon Doksuri will continue to drop heavy rain on parts of Taiwan during the next 24 hours. The heaviest rain will fall initially on the eastern side of mountains where the winds around Doksuri will push air up the slopes. Heavy rain could fall on the western sides of mountains when Typhoon Doksuri moves farther north and the wind over Taiwan blows from the south. Heavy rain is likely to cause flash floods in some locations.

Elsewhere over the Western North Pacific Ocean, a new tropical depression formed east of the Philippines. At 11:00 a.m. EDT on Thursday the center of Tropical Depression 06W was located at latitude 12.7°N and longitude 137.5°E which put it about 170 miles (275 km) northwest of Yap. The tropical depression was moving toward the west-northwest at 16 m.p.h. (26 km/h). The maximum sustained wind speed was 30 m.p.h. (50 km/h) and there were wind gusts to 40 m.p.h. (65 km/h). The minimum surface pressure was 1003 mb. Tropical Depression 06W is forecast to move toward the Ryukyu Islands and to strengthen to a typhoon.

Typhoon Doksuri Drops Heavy Rain on Taiwan

Typhoon Doksuri dropped heavy rain on parts of Taiwan on Wednesday. At 5:00 p.m. EDT on Wednesday the center of Typhoon Doksuri was located at latitude 20.3°N and longitude 119.9°E which put it about 150 miles (240 km) south-southwest of Kaohsiung Taiwan. Doksuri was moving toward the west at 7 m.p.h. (11 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 947 mb.

Bands in the northern side of Typhoon Doksuri dropped heavy rain on parts of Taiwan on Wednesday. The heaviest rain was falling in eastern Taiwan, where the wind was pushing the air up the eastern slopes of mountains.. There were reports of flooding in the northern Philippines after the southern part of Doksuri dropped heavy rain in that region. There were also reports of casualties and electricity outages in the northern Philippines.

Typhoon Doksuri exhibited more organization on Wednesday after the core of Doksuri’s circulation started to move away from northern Luzon. Radar images from Taiwan’s Central Weather Bureau showed what appeared to concentric eyewalls at the core of Typhoon Doksuri. A small circular eye was at the center of Doksuri’s circulation. The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms. The inner eyewall was surrounded by a relatively clear area, sometimes called a moat. A much larger, outer eyewall surrounded the inner eyewall and moat. Bands of showers and thunderstorms were revolving around the concentric eyewalls. Storms in the concentric eyewalls generated upper level divergence that pumped mass away from the typhoon.

Doksuri was still a large typhoon. Winds to typhoon force extended out 70 miles (110 km) from the center of Doksuri’s circulation. Winds to tropical storm force extended out 200 miles (320 km) from the center. The Hurricane Intensity Index (HII) for Typhoon Doksuri was 17.8. The Hurricane Size Index (HSI) was 23.1 and the Hurricane Wind Intensity Size Index (HWISI) was 40.9. Typhoon Doksuri was similar in size and intensity to Hurricane Gustav when Gustav Hit Louisiana in 2008. Doksuri was capable of causing widespread serious damage.

Typhoon Doksuri will move through an environment favorable for intensification during the next 24 hours. Doksuri 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, the concentric eyewalls at the center of Typhoon Doksuri will inhibit intensification. Doksuri could weaken until the inner eye and eyewall dissipate. The strength of Typhoon Doksuri may not change much during the next 24 hours.

Typhoon Doksuri will move around the southwestern side of a subtropical high pressure system over the Western North Pacific Ocean. The high pressure system will steer Doksuri toward the northwest during the next 36 hours. On its anticipated track, the core of Typhoon Doksuri will pass southwest of Taiwan. Typhoon Doksuri will continue to drop heavy rain on parts of Taiwan during the next 24 hours. The heaviest rain will fall on the eastern side of mountains where the winds around Doksuri will push air up the slopes. Heavy rain is likely to cause flash floods in some locations.

Typhoon Doksuri will approach the east coast of China near Xiamen in 24 hours. Doksuri will bring strong winds and heavy rain to Fujian. Heavy rain could cause flash floods in some locations. Typhoon Doksuri could also cause a storm surge of up to 10 feet (3 meters) along the coast of Fujian.
