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.

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.

Powerful Typhoon Hagibis Continues Toward Honshu

Powerful Typhoon Hagibis continue to move toward Honshu on Wednesday.  At 11:00 p.m. EDT on Wednesday the center of Typhoon Hagibis was located at latitude 23.7°N and longitude 139.5°E which put it about 140 miles (225 km) west-southwest of Iwo To.  Hagibis was moving toward the north at 14 m.p.h. (22 km/h).  The maximum sustained wind speed was 160 m.p.h. (260 km/h) and there were wind gusts to 195 m.p.h. (315 km/h).  The minimum surface pressure was 918 mb.

Typhoon Hagibis continued to have a powerful, large circulation on Wednesday.  A circular eye with a diameter of 25 miles (40 km) was at the center of circulation.  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 Hagibis.  The rainbands in the northwestern quadrant of Hagibis were a little weaker than the bands in other parts of the typhoon.  Some drier air may have been being pulled into the the northwestern quadrant of the circulation.  Storms around the core of the typhoon continue to generate strong upper level divergence.

The strength of the winds around Typhoon Hagibis exhibited more asymmetry on Wednesday.  Winds to typhoon force extended out 150 miles (240 km) from the center of circulation in the northeastern part of Hagibis.  Winds to typhoon force were occurring within 100 miles (160 km) of the center in the other parts of Typhoon Hagibis.  Winds to tropical storm force extended out 370 miles (565 km) from the center.  The Hurricane Intensity Index (HII) for Typhoon Hagibis was 35.0.  The Hurricane Size Index (HSI) was 39.9 and he Hurricane Wind Intensity Size Index (HWISI) was 74.9.  Typhoon Hagibis was capable of causing extensive catastrophic damage.

Typhoon Habigis will continue to move through an environment capable of supporting strong  typhoons, but Hagibis is likely to start to weaken on Thursday.  Typhoon Hagibis will move over water where the Sea Surface Temperature is near 29°C, but that is slightly cooler than the water Hagibis has been over.  Typhoon Hagibis will move through a region where the upper level winds are weak during the next 24 hours.  There will be little vertical wind shear on Thursday, and so Hagibis will likely weaken slowly.  Typhoon Hagibis will move closer to upper level westerly winds in the middle latitudes on Friday.  When Hagibis gets closer to the stronger upper level winds, vertical wind shear will increase and the typhoon will weaken more quickly.  The large circulation around Typhoon Hagibis will slow the rate of weakening even when the wind shear increases.

Typhoon Hagibis will move around the western end of a subtropical high pressure system over the Western North Pacific Ocean during the next 24 hours.  The high will steer Hagibis toward the north on Thursday.  Typhoon Hagibis will move toward the northeast on Friday when it reaches the upper level westerly winds.  On its anticipated track the center of Typhoon Hagibis will move west of Iwo To during the next 24 hours.  Hagibis will bring winds to tropical storm force to Iwo To and there is a chance that the winds could reach typhoon force at times.  Rainbands on the eastern side of the typhoon will drop heavy rain on Iwo To.  Typhoon Hagibis could approach the coast of Honshu near Tokyo in a little over 48 hours.  Hagibis will still be a typhoon when it approaches Tokyo.  It will bring strong winds and heavy rain to parts of Honshu.  Typhoon Hagibis could also produce winds to tropical storm force on Shikoku.

Large Powerful Typhoon Hagibis Turns Toward Japan

Large powerful Typhoon Hagibis turned toward Japan on Tuesday.  At 11:00 p.m. EDT on Tuesday the center of Typhoon Hagibis was located at latitude 20.2°N and longitude 140.1°E which put it about 350 miles (565 km) south of Iwo To.  Hagibis was moving toward the northwest at 10 m.p.h. (16 km/h).  The maximum sustained wind speed was 160 m.p.h. (260 km/h) and there were wind gusts to 195 m.p.h. (315 km/h).  The minimum surface pressure was 915 mb.

Typhoon Hagibis appeared to complete an eyewall replacement cycle on Tuesday.  The original tiny pinhole eye was no longer visible on satellite imagery.  A larger circular eye with a diameter of 24 miles (39 km) was at the center of Hagibis.  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 Hagibis.  Storms around the core were generating strong upper level divergence which was pumping mass away from the typhoon in all directions.

Completion of the eyewall replacement cycle increased the size of the circulation around Typhoon Hagibis.  Winds to typhoon force extended out 115 miles (185 km) from the center of circulation.  Winds to tropical storm force extended out 350 miles (565 km) from the center.  The Hurricane Intensity Index (HII) for Typhoon Hagibis was 35.0.  The Hurricane Size Index (HSI) was 38.1 and the Hurricane Wind Intensity Size Index (HWISI) was 73.1.  Hagibis was capable of causing extensive catastrophic damage.

Typhoon Hagibis will move through an environment capable of supporting intense typhoons during the next 24 to 36 hours.  Hagibis will move over water where the Sea Surface Temperature is near 30°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Typhoon Hagibis will move closer to the upper level westerly winds in the middle latitudes in two or three days.  Those winds will cause more vertical wind shear and Hagibis will weaken when the shear increases.

Typhoon Hagibis will move around the western end of a subtropical high pressure system over the Western North Pacific Ocean.  The high will steer Hagibis toward the north-northwest during the next 48 hours.  The upper level westerly winds will steer Typhoon Hagibis quickly toward the northeast later this week.  On its anticipated track the center of Typhoon Hagibis could approach the coast of Honshu near Tokyo in 72 to 84 hours.  Hagibis could bring strong winds and heavy rain to Tokyo.  The large circulation around Typhoon Hagibis will mean that much of central Honshu could experience gusty winds and winds to tropical storm force could affect parts of Kyushu and Shikoku.

Tropical Storm Krosa Brings Wind and Rain to Southwest Japan

Large Tropical Storm Krosa brought wind and rain to parts of southwestern Japan on Wednesday night.  At 11:00 p.m. EDT on Wednesday the center of Tropical Storm Krosa was located at latitude 33.2°N and longitude 132.9°E which put it about 20 miles (30 km) south-southwest of Uwajima, Japan.  Krosa was moving toward the north 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 975 mb.

The center of large Tropical Storm Krosa was near the southwestern coast of Shikoku on Wednesday night.  The strongest winds were blowing in rainbands that were east of the center of circulation.  Winds to tropical storm force extended out about 260 miles (420 km) from the center of circulation.  The wind was weaker in the western half of Krosa.

Heavy rain was falling on the south facing slopes of Shikoku where the wind was blowing up the slopes.  Heavy rain was also falling on south facing slopes in Wakayama, Mie, Nara and Shiga prefectures in Honshu.  Prolonged heavy rainfall could cause flash floods in some locations.

Tropical Storm Krosa is forecast to move north-northeast across Shikoku and southwestern Honshu.  Krosa will weaken when it moves over land, but it will continue to drop heavy rain over parts of southwestern Japan on Thursday.  A weaker Tropical Storm Krosa is forecast to move over the Sea of Japan later on Thursday.

Large Tropical Storm Krosa Moves Toward Southwest Japan;

Large Tropical Storm Krosa moved toward southwestern Japan on Tuesday.  At 5:00 p.m. EDT on Tuesday the center of Tropical Storm Krosa was located at latitude 28.7°N and longitude 133.4°E which put it about 330 miles (530 km) south of Kochi, Japan.  Krosa 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 965.

The circulation around Tropical Storm Krosa was large.  Krosa has a broad center of circulation which spanned almost 120 miles (195 km).  Several bands of showers and thunderstorms appeared to be consolidating into a broken ring around the broad center.  The strongest winds were occurring in the broken ring.  Other bands of showers and thunderstorms were revolving around the broad center of circulation.  Winds to tropical storm force extended out about 265 miles (425 km) from the center of circulation.

Tropical Storm Krosa will move through an environment favorable for intensification during the next 12 to 24 hours.  Krosa will move over water where the Sea Surface Temperature is near 28.5°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Tropical Storm Krosa is under an upper level ridge which is enhancing the upper level divergence.  However, the large, broad center of circulation will limit the rate of any intensification.  Krosa could strengthen into a typhoon before it reaches southwestern Japan.

Tropical Storm Krosa is moving around the western end of a subtropical ridge over the Western North Pacific Ocean.  Krosa will move more toward the north when it reaches the western end of the ridge.  On its anticipated track Tropical Storm Krosa could reach southwestern Japan within 18 to 24 hours.  Krosa could be a typhoon by that time.  Tropical Storm Krosa will bring gusty winds and heavy rain to parts of Kyushu, Shikoku, and western Honshu.  Heavy rain is likely to cause flooding in some location, especially in areas with steeper slopes.

Typhoon Francisco Brings Wind and Rain to Kyushu

Typhoon Francisco brought wind and rain to Kyushu on Monday.  At 5:00 p.m. EDT on Monday the center of Typhoon Francisco was located at latitude 32.2°N and longitude 131.4°E which put it about 20 miles (35 km) north of Miyazaki, Japan.  Francisco was moving toward the west-northwest at 13 m.p.h. (20 km/h).  The maximum sustained wind speed was 85 m.p.h. (135 km/h) and there were wind gusts to 100 m.p.h. (160 km/h).  The minimum surface pressure was 969 mb.

Typhoon Francisco strengthened on Monday as it neared the coast of Kyushu.  A small eye developed at the center of circulation.  A ring of strong thunderstorms surrounded the eye and the strongest winds were occurring in that ring of storms.  Several bands of showers and thunderstorms were revolving around the core of Typhoon Francisco.  The stronger bands were primarily in the eastern half of the circulation.

The core of Typhoon Francisco made landfall on Kyushu just to the north of Miyazaki.  Typhoon Francisco will bring very heavy rain and strong gusty winds to much of Kyushu.  Francisco is forecast to turn toward the northwest and the center of circulation will move across the middle of Kyushu.  Locally heavy rain falling on steep terrain will create the potential for serious flash flooding in some locations.  Rainbands in the eastern half of Typhoon Francisco will also drop locally heavy rain over parts of western Shikoku and western Honshu.

Typhoon Francisco will weaken when it moves across Honshu, but then it will move over the Korea Strait and make another landfall in South Korea.  Francisco will bring gusty winds and locally heavy rain to parts of southern South Korea on Tuesday.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Lekima continue to meander east of Luzon.  At 11:00 a.m. EDT on Monday the center of Tropical Storm Lekima was located at latitude 18.7° and longitude 129.3°E which put it about 670 miles (1085 km) south-southeast of Taipei, Taiwan.  Lekima was moving toward the southwest at 6 m.p.h. (10 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.

Typhoon Kong-rey Brings Wind and Rain to Okinawa

Typhoon Kong-rey was bringing wind and rain to Okinawa on Wednesday night.  At 11:00 p.m. EDT on Wednesday the center of Typhoon Kong-rey was located at latitude 23.6°N and longitude 127.3°W which put it about 230 miles (375 km) south of Okinawa.  Kong-rey was moving toward the northwest at 10 m.p.h. (16 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 964 mb.

Typhoon Kongrey weakened steadily during Wednesday.  The eye became less distinct on satellite imagery.  The ring of strong thunderstorms around the eye broke and stronger thunderstorms were only occurring to the east of the eye.  It appeared that Typhoon Kong-rey was pulling cooler, drier air into the western half of the circulation and that air was wrapping around the southern half of the typhoon.  Kong-rey may have also moved over some cooler water that was mixed to the surface by Typhoon Trami last week.

The circulation around Typhoon Kong-rey was still large.  Winds to typhoon force extended out about 70 miles (110 km) from the center of circulation.  Winds to tropical storm force extended out about 230 miles (375 km) from the center.  The Hurricane Intensity Index (HII) for Typhoon Kong-rey was 11.5.  The Hurricane Size Index (HSI) was 24.7 and the Hurricane Wind Intensity Size Index (HWISI) was 36.2.

Typhoon Kong-rey will move around the western end of a subtropical ridge over the Western North Pacific Ocean.  The ridge will steer Kong-rey toward the north during the next 24 to 36 hours.  Typhoon Kong-rey will turn more toward the northeast in about 36 hours.

The outer rainbands on the northern side of Typhoon Kong-rey are already over Okinawa.  Kong-rey will drop heavy rain and it will produce gusty winds over Okinawa and the Ryukyu Islands on Thursday.  The wind and rain will hinder efforts to recover from damage caused by Typhoon Trami.  Typhoon Kong-rey could be southeast of Kyushu in about 36 hours and it could be near South Korea in about 48 hours.  The soil in much of Japan is already near saturation and more heavy rain could cause flash flooding.  Typhoon Kong-rey could also hinder recovery efforts in Kyushu, Shikoku and Honshu.
