Typhoon Koinu Brings Wind and Rain to Taiwan

Typhoon Koinu brought wind and rain to Taiwan on Wednesday night. At 11:00 p.m. EDT on Wednesday the center of Typhoon Koinu was located at latitude 22.1°N and longitude 120.6°E which put it about 10 miles (15 km) west of Hengchun, Taiwan. Koinu was moving toward the west-northwest at 5 m.p.h. (8 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 945 mb.

Typhoon Koinu brought strong winds and heavy rain to southern Taiwan on Wednesday night. The eye of Koinu passed over the southern tip of Taiwan. The northern half of the eyewall moved across southern Taiwan. Typhoon Koinu was the equivalent of a major hurricane when it moved across Taiwan. Winds to typhoon force extended out 70 miles (110 km) from the center of Koinu’s circulation. Winds to tropical storm force extended out 230 miles (370 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Koinu was 23.6. The Hurricane Size Index (HSI) was 21.6 and the Hurricane Wind Intensity Size Index (HWISI) was 45.2. Typhoon Koinu was stronger than Hurricane Rita was when Rita hit southwest Louisiana in 2005. Koinu was a little smaller than Rita was.

Easterly winds blowing around the northern side of Typhoon Koinu will rise up the eastern slopes of mountains in Taiwan. The enhanced rising motion will produce very heavy rainfall on those eastern slopes. The heavy rain is likely to cause flash floods in some locations.

Typhoon Koinu will move will move around the southern part of a high pressure system over eastern Asia and the Western North Pacific Ocean. The high pressure system will steer Koinu toward the west during the next 24 hours. On its anticipated track the center Typhoon Koinu will move over the South China Sea on Thursday.

The core of Typhoon Koinu was partially disrupted when the eye and northern part of the eyewall moved across southern Taiwan. The disruption of the inner core of Koinu’s circulation is likely to cause Typhoon Koinu to weaken during the next 24 hours even though Koinu will move through an environment favorable for intensification. Koinu will move over water where the Sea Surface Temperatures are near 28°C. It will move under the southern part of an upper level ridge over China. The ridge will produce easterly winds that will blow toward the top of Koinu’s circulation. Those winds will cause some little vertical wind shear, but the wind shear will not be too strong. Typhoon Koinu is likely to weaken gradually during the next 24 hours because of the disruption of its inner core.

Typhoon Koinu Approaches Taiwan

The minimum surface pressure was 966 mb.

Typhoon Haikui brought strong winds and heavy rain to Taiwan on Sunday. A weather station at the airport in Taipei (RCTP) reported a sustained wind speed of 35 m.p.h. (55km/h) and a wind gust of 49 m.p.h. (79 km/h). A weather station in Taitung (RCFN) reported a sustained wind speed of 56 m.p.h. (91 km/h) and a wind gust of 87 m.p.h. (140 km/h). A weather station in Kaohsiung (RCKH) reported a sustained wind speed of 39 m.p.h. (63 km/h) and a wind gust of 62 m.p.h. (100 km/h). Bands in the eastern part of Typhoon Haikui were still dropping heavy rain over parts of Taiwan on Sunday night.

The lower levels of the circulation of Typhoon Haikui were disrupted when Haikui moved over the mountains on Taiwan. There was no longer an eye at the center of Haikui’s circulation. The circulation in the middle and upper level of Typhoon Haikui remained relatively intact. Bands of showers and thunderstorms were revolving around the center of Haikui’s circulation. Winds to typhoon force extended out 30 miles (50 km/h) from the center of circulation. Winds to tropical storm force extended out 165 miles (265 km) from the center of Typhoon Haikui.

Typhoon Haikui will move around the southern side 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 approach the east coast of China between Shantou and Xiamen within 24 hours.

Typhoon Haikui will move through an environment favorable for intensification during the next 24 hours. Haikui will move over water where the Sea Surface Temperatures are near 30°C. It will move under an upper level ridge centered northwest of Taiwan. The upper level winds are weak in the ridge and the will be little vertical wind shear. Typhoon Haikui may not intensify during the next 24 hours even though it will move through a favorable environment. The lower levels of Haikui’s circulation will gradually reorganize now that the center of circulation is back over water. However, there may not be enough time for an eye to develop again before Haikui reaches the east coast of China. If the inner core of Typhoon Haikui does not develop again, then it will be unlikely to strengthen.

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.

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.

(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.

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.
