Tropical Storm Nanmadol Brings Wind and Rain to Japan

Tropical Storm Nanmadol brought wind and rain to Japan on Sunday. At 11:00 p.m. EDT on Sunday the center of Tropical Storm Nanmadol was located at latitude 34.5°N and longitude 131.9°E which put it about 30 miles (50 km) west of Hiroshima, Japan. Nanmadol was moving toward the north-northeast at 13 m.p.h. (20 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 976 mb.

Former Typhoon Nanmadol weakened to a strong tropical storm as it moved inland over Kyushu on Sunday. The circulation around Tropical Storm Nanmadol was still large. Winds to tropical storm force extended out 275 miles (445 km) from the center of Nanmadol. The strongest winds and heaviest rain were occurring in band in the eastern and northern parts of Nanmadol. Bands in the southern and western parts of Tropical Storm Nanmadol consisted primarily of showers and lower clouds.

The eye of then Typhoon Nanmadol moved over Kagoshima earlier on Sunday. A weather station in Kagoshima measured a surface pressure of 940.8 mb. The same weather station also measured 7.10 inches (180 mm) of rain. Heavy rain fell over many other locations in Kyushu and there were reports of flash floods in some locations.

An upper level trough northwest of Japan will steer Tropical Storm Nanmadol quickly toward the northeast during the next 36 hours. On its anticipated track Tropical Storm Nanmadol will move over much of Honshu. Nanmadol will bring gusty winds and locally heavy rain to Shikoku and Honshu. Heavy rain could cause flash floods in some locations.

Typhoon Nanmadol Brings Strong Wind and Heavy Rain to Kyushu

Typhoon Nanmadol brought strong winds and heavy rain to Kyushu on Sunday morning. At 5:00 a.m. EDT on Sunday the center of Typhoon Nanmadol was located at latitude 31.1°N and longitude 130.6°E which put it about 40 miles (65 km) south of Kagoshima, Japan. Nanmadol 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 969 mb.

The center of Typhoon Nanmadol was moving inland over Kyushu on Sunday morning. Nanmadol was a large an powerful typhoon. Winds to typhoon force extended out 75 miles (120 km) from the center of Nanmadol. Winds to tropical storm force extended out 250 miles (400 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Nanmadol was 19.2. The Hurricane Size Index (HSI) was 30.2 and the Hurricane Wind Intensity Size Index (HWISI) was 51.1. Typhoon Nanmadol was capable of causing extensive serious damage.

Typhoon Nanmadol will move around the western end of a high pressure system over the Western North Pacific Ocean during the next 12 hours. The high pressure system will steer Nanmadol toward the north during that time. On its anticipated track the center of Typhoon Nanmadol will continue to move farther inland over Kyushu. Nanmadol will continue to produce strong gusty winds and locally heavy rain to Kyushu. Heavy rain is likely to cause flash floods in some locations. The westerly winds in the middle latitudes will Nanmadol toward the northeast later today. Typhoon Nanmadol will move over Honshu tomorrow. Nanmadol will bring strong winds and heavy rain to much of Honshu and Shikoku, when it moves northeastward.

Typhoon Nanmadol Near Yakushima

The center of Typhoon Nanmadol was near Yakushima on Saturday night. At 11:00 p.m. EDT on Saturday the center of Typhoon Nanmadol was located at latitude 30.2°N and longitude 130.8°E which put it about 90 miles (145 km) south of Kagoshima, Japan. Nanmadol was moving toward the north-northwest at 14 m.p.h. (22 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 951 mb.

The eye of Typhoon Nanmadol was just southeast of Yakushima on Saturday night. The northwestern part of the eyewall was over Yakushima. Bands on the northern side of Typhoon Nanmadol were producing gusty winds and locally heavy rain over Kyushu.

Nanmadol was a large typhoon. Winds to typhoon force extended out 70 miles (110 km) from the center of Typhoon Nanmadol. Winds to tropical storm force extended out 275 miles (445 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Nanmadol was 22.1. The Hurricane Size Index (HSI) was 29.0 and the Hurricane Wind Intensity Size Index (HWISI) was 51.1. Typhoon Nanmadol was capable of causing widespread serious damage.

Typhoon Nanmadol will move around the western end of a high pressure system over the Western North Pacific Ocean during the next 24 hours. The high pressure system will steer Nanmadol toward the north during the next 24 hours. On its anticipated track the center of Typhoon Nanmadol will reach southwestern Kyushu in a few hours. Nanmadol will bring strong gusty winds and locally heavy rain to Kyushu. Heavy rain is likely to cause flash floods in some locations. The westerly winds in the middle latitudes will Nanmadol toward the northeast in a day or so. Typhoon Nanmadol will move over Honshu early next week. Nanmadol will bring strong winds and heavy rain to Honshu and Shikoku.

Powerful Typhoon Nanmadol Is East of Okinawa

Powerful Typhoon Nanamadol was east of Okinawa on Friday night. At 11:00 p.m. EDT on Friday the center of Typhoon Nanmadol was located at latitude 26.4°N and longitude 132.7°E which put it about 330 miles (530 km) east of Okinawa. Nanmadol was moving toward the northwest at 9 m.p.h. (15 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 926 mb.

Powerful Typhoon Nanmadol was churning over the Western North Pacific Ocean east of Okinawa on Friday night. A circular eye with a diameter of 23 miles (37 km) was present at the center of Nanmadol. The 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 core of Typhoon Nanmadol. Storms near the core generated upper level divergence that pumped mass away from the typhoon in all directions.

The size of the circulation around Typhoon Nanmadol increased on Friday when Nanmadol intensified. Winds to typhoon force extended out 100 miles (160 km) from the center of Nanmadol. Winds to tropical storm force extended out 260 miles (420 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Nanmadol was 31.6. The Hurricane Size Index (HSI) was 28.0 and the Hurricane Wind Intensity Size Index (HWISI) was 59.6. Typhoon Nanmadol was capable of causing widespread severe damage.

Typhoon Nanmadol will move through an environment capable of supporting a powerful typhoon during the next 24 hours. Nanmadol will move over water where the Sea Surface Temperatures are near 29˚C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Typhoon Nanmadol could maintain much of its intensity during the next 24 hours. If the inner end of a rainband wraps around the existing eye and eyewall, then concentric eyewalls could form. That would be the start of an eyewall replacement cycle that would cause Nanmadol to weaken.

Typhoon Nanmadol will move around the southwestern part of a high pressure system over the Western North Pacific Ocean. The high pressure system will steer Nanmadol toward the northwest during the next 24 hours. On its anticipated track the center of Typhoon Nanmadol will be east of Minami Daito Jima within 12 hours. Nanmadol could be east of Amami Oshima in 24 hours. Typhoon Nanmadol will bring strong, gusty winds and heavy rain to parts of the northern Ryukyu Islands during the weekend. Nanmadol could be near western Kyushu in 36 hours.

Tropical Storm Chanthu Brings Gusty Winds and Rain to Japan

Tropical Storm Chanthu brought gusty winds and rain to parts of Japan on Friday. At 6:00 a.m. EDT on Friday the center of Tropical Storm Chanthu was located at latitude 33.7°N and longitude 130.6°E which put it about 10 miles (15 km) east of Fukuoka, Japan. Chanthu was moving toward the east-northeast at 17 m.p.h. (28 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 990 mb.

Tropical Storm Chanthu brought gusty winds to northern Kyushu and western Honshu on Friday. Winds to tropical storm force extended out 115 miles (185 km) from the center of Chanthu. The strongest winds were occurring in the parts of Chanthu’s circulation that were over water and in the mountains of western Japan. The heaviest rain was falling on the eastern side of Tropical Storm Chanthu.

Tropical Storm Chanthu will be steered quickly toward the east-northeast by the westerly winds in the middle latitudes. Tropical Storm Chanthu will move across Honshu during the next two days. The center of Tropical Storm Chanthu could be near Kyoto in 24 hours and near Tokyo in 36 hours. The upper level westerly winds will cause moderate vertical wind shear. The wind shear and movement across land will cause Chanthu to weaken gradually during the next 48 hours.

Tropical Storm Chanthu Spins between Japan and China

Tropical Storm Chanthu spun between Japan and China on Wednesday. At 5:00 p.m. EDT on Wednesday the center of Tropical Storm Chanthu was located at latitude 30.5°N and longitude 125.2°E which put it about 360 miles (585 km) west-southwest of Kagoshima, Japan. Chanthu was moving toward the northwest at 4 m.p.h. (6 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 991 mb.

Tropical Storm Chanthu remained nearly stationary on Wednesday as it spun over the East China Sea between Japan and China. The atmospheric environment around Chanthu became more favorable for intensification when an upper level ridge moved over the tropical storm. Chanthu strengthened when the upper level ridge enhanced the upper level divergence that pumped more mass away from the tropical storm. The enhanced upper level divergence also contributed to the formation of more thunderstorms in the bands revolving around the center of Tropical Storm Chanthu. A rainband wrapped most of the way around the center of Chanthu and a new eye appeared to be forming at the center of the tropical storm. Winds to tropical storm force extended out 190 miles (305 km) on the northern side of Chanthu. Winds to tropical storm force extended out 90 miles (145 km) in the southern half of the circulation.

Tropical Storm Chanthu will move through an environment somewhat favorable for intensification during the next 24 hours. Chanthu will move over water where the Sea Surface Temperature is near 27˚C. Chanthu could mix cooler water to the surface while it remains nearly stationary, which could inhibit intensification. The upper level ridge will continue to enhance divergence, which will be favorable for intensification. Tropical Storm Chanthu is likely to intensify during the next 24 hours and it could strengthen back to a typhoon.

The steering winds are weak in the middle of the upper level ridge and Tropical Storm Chanthu may not move much during the next 12 to 18 hours. An upper level trough over eastern Asia will move eastward on Thursday. The upper level trough will start to steer Chanthu toward the west in 12 to 18 hours. On its anticipated track Tropical Storm Chanthu could approach Kyushu in 30 hours. Chanthu could be a typhoon when it reaches Kyushu. It will bring strong, gusty winds and locally heavy rain. Heavy rain could cause flash floods in some locations.

Tropical Storm Lupit Brings Rain to Japan

Tropical Storm Lupit brought rain to Japan on Sunday. At 11:00 a.m. EDT on Sunday the center of Tropical Storm Lupit was located at latitude 32.3°N and longitude 131.6°E which put it about 20 miles (30 km) southwest of Miyazaki, Japan. Lupit was moving toward the east-northeast at 26 m.p.h. (42 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 990 mb.

Tropical Storm Lupit made landfall on the coast of Kyushu near Kagoshima on Sunday. Lupit was being steered quickly toward the east-northeast by an upper level trough near the Korean Peninsula. The trough was producing strong southwesterly winds that were blowing toward the top of Lupit’s circulation. Those winds were causing strong vertical wind shear and they were affecting the distribution of rain in Tropical Storm Lupit. Most of the heavier rain was falling in bands north and east of the center of Lupit. The heavier rain was falling over Shikoku, northern Kyushu and southwestern Honshu. Bands south and west of the center of circulation consisted primarily of showers and lower clouds. The strongest winds were occurring in the southern half of Tropical Storm Lupit. Winds to tropical storm force extended out 160 miles (260 km) on the south side of Lupit. The winds in the northern half of the circulation were blowing at less than tropical storm force.

The trough near the Korean Peninsula will steer Tropical Storm Lupit quickly toward the northeast during the next 36 hours. On its anticipated track the center of Lupit will move over the southern Sea of Japan. The center of Tropcial Storm Lupit could be near northern Honshu in 36 hours. Rain will spread over the rest of Honshu and Hokkaido during the next two days. Locally heavy rain could cause flash floods in some locations.

Tropical Storm Lupit will move through an environment only marginally favorable for intensification. Lupit will move over water in the Sea of Japan where the Sea Surface Temperatures are near 28°C. However, the upper level trough will continue to cause strong vertical wind shear. The lower part of Lupit’s circulation will also be disrupted while it passes over land. Tropical Storm Lupit is not likely to strengthen significantly and it could weaken if the center does not move over the Sea of Japan.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Mirinae was moving eastward away from Japan. At 11:00 a.m. EDT on Sunday the center of Tropical Storm Mirinae was located at latitude 36.6°N and longitude 144.7°E which put it about 230 miles (370 km) east-northeast of Tokyo, Japan. Mirinae was moving toward the northeast at 18 m.p.h. (30 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 990 mb.

Typhoon Chan-hom Turns Toward Japan

Typhoon Chan-hom turned toward Japan on Wednesday.  At 5:00 p.m. EDT on Wednesday the center of Typhoon Chan-hom was located at latitude 27.5°N and longitude 132.9°W which put it about 515 miles (825 km) south-southwest of Osaka, Japan.  Chan-hom was moving toward the 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 973 mb.

Typhoon Chan-hom strengthened slowly on Wednesday.  An eye with a diameter of 35 miles (55 km) formed at the center of Chan-hom.  The eye was surrounded by a broken 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 Chan-hom.  Storms near the core generated upper level divergence which pumped mass away to the northeast of the typhoon.

The circulation around Typhoon Chan-hom was large.  Winds to typhoon force extended out 60 miles (95 km) from the center of circulation.  Winds to tropical storm force extended out 200 miles (320 km) from the center of Chan-hom.

Typhoon Chan-hom will move through an environment somewhat favorable for intensification during the next 24 hours.  Chan-hom will move over water where the Sea Surface Temperature is near 28°C.  It will move under the western end of an upper level ridge.  The ridge will produce southerly winds which will blow toward the top of Typhoon Chan-hom.  Those winds will cause moderate vertical wind shear, which will inhibit intensification.  The wind shear will limit intensification, but Chan-hom could get stronger during the next 24 hours.  An upper level trough over eastern Asia will cause stronger southwesterly winds to blow toward Typhoon Chan-hom in a day or so.  Those winds will cause stronger vertical wind shear and they will cause Chan-hom to start to weaken.

Typhoon Chan-hom will move around the western end of a subtropical high pressure system over the Western North Pacific Ocean during the next 48 hours.  The high will steer Chan-hom toward the north during that time period.  The upper trough over eastern Asia will turn Typhoon Chan-hom toward the northeast during the weekend.  On its anticipated track Typhoon Chan-hom will be southeast of Kyushu and south of Shikoku in about 48 hours.

Typhoon Haishen Drops Heavy Rain over South Korea

Typhoon Haishen dropped heavy rain over South Korea on Sunday night. Haishen weakened to a tropical storm after it made landfall on South Korea.   At 11:00 p.m. EDT on Sunday the center of Tropical Storm Haishen was located at latitude 36.6°N and longitude 128.8°E which put it about 30 miles north-northwest of Busan, South Korea.  Haishen was moving toward the north at 27 m.p.h. (43 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 969 mb.

The center of Typhoon Haishen passed just to the west of Kyushu earlier on Sunday.  A weather station at Makurazaki, Japan reported a wind speed of 65 m.p.h. (105 km/h) and a pressure of 966.6 mb.

Typhoon Haishen began dropping heavy rain over parts of South Korea hours before the center made landfall west of Busan.  Heavy rain was falling on some of the same places that also received heavy rain from Typhoon Maysak a few days ago.  The additional rain will cause flash floods in some locations.  Tropical Storm Haishen will continue to weak as it moves rapidly toward the north.

Typhoon Haishen Brings Wind and Rain to Northern Ryukyu Islands

Typhoon Haishen brought wind and rain to the northern Ryukyu Islands on Saturday.  At 11:00 p.m. EDT on Saturday the center of Typhoon Haishen was located at latitude 28.3°N and longitude 130.4°E which put it about 170 miles (280 km) east-northeast of Okinawa.  Haishen was moving toward the north-northwest at 15 m.p.h. (24 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 945 mb.

The center of Typhoon Haishen passed west of Minami-Daito Jima on Saturday.  A weather station there measured a wind speed of 72 m.p.h. (116 km/h) and a pressure of 943.6 mb.

The circulation around around Typhoon Haishen developed concentric eyewalls on Saturday.  The smaller original eyewall started to weaken as low level convergence became more concentrated into the much larger outer eyewall.  The strongest winds were originally found in the inner eyewall, but those wind speeds decreased.  The stronger winds were blowing in the larger outer eyewall on Saturday night.

The concentric eyewall structure produced an increase in the size of the circulation around Typhoon Haishen.  Winds to typhoon force extended out 100 miles (160 km) from the center of circulation.  Winds to tropical storm force extended out 325 miles (530 km) from the center.  The Hurricane Intensity Index (HII) for Typhoon Haishen was 19.2.  The Hurricane Size Index (HSI) was 37.2 and the Hurricane Wind Intensity Size Index (HWISI) was 56.4.  Typhoon Haishen was capable of causing widespread serious damage.

Typhoon Haishen will move into a less favorable environment during the next 24 hours.  Haishen will move over water where the Sea Surface Temperature is near 28°C.  Drier air over Asia will get pulled into the circulation.  Wind shear will increase when Typhoon Haishen moves farther north because it will get closer to the upper level westerly winds in the middle latitudes.  The effects of the concentric eyewalls, drier air and more wind shear will cause Typhoon Haishen to gradually weaken.

Typhoon Haishen will move around the western end of a subtropical high pressure system over the Western North Pacific Ocean.  The high will steer Haishen toward the north.  On its anticipated track the center of Typhoon Haishen will pass near the western part of Kyushu in about 12 hours.  Haishen will reach South Korea in about 24 hours.  Typhoon Haishen will bring strong winds and heavy rain to parts of Kyushu and South Korea.  Heavy rain could cause flash floods, especially in places that received heavy rain from Typhoon Maysak a few days ago.
