Dangerous Typhoon Mangkhut Approaches Northern Luzon

Dangerous Typhoon Mangkhut approached northern Luzon on Thursday night.  At 11:00 p.m. EDT on Thursday the center of Typhoon Mangkhut was located at latitude 16.2°N and longitude 126.2°E which put it about 400 miles (645 km) east-northeast of Manila.  Mangkhut was moving toward the northwest at 14 m.p.h.  The maximum sustained wind speed was 170 m.p.h. (280 km/h) and there were wind gusts to 205 m.p.h. (335 km/h).  The minimum surface pressure was 905 mb.

Typhoon Mangkhut has a large powerful circulation.  There is a circular eye with a diameter of about 30 miles (50 km) at the center of circulation.  A number of bands of showers and thunderstorms are revolving around the core of the circulation.  Storms around the core were generating strong upper level divergence which was pumping mass away from the typhoon in all directions.

Winds to typhoon force extended out about 100 miles (160 km) from the center of circulation.  Winds to tropical storm force extended out about 265 miles (425 km) from the center.  The Hurricane Intensity Index (HII) for Typhoon Mangkhut was 38.5.  The Hurricane Size Index (HSI) was 33.7 and the Hurricane Wind Intensity Size Index (HWISI) was 72.2.  Those indices indicate that Typhoon Mangkhut is very similar in size and strength to what Hurricane Katrina was when Katrina was a Category 5 hurricane over the Gulf of Mexico in 2005.

Typhoon Mangkhut will move through an environment that is very favorable for strong typhoons during the next 12 to 18 hours.  Mangkhut will move over water where the Sea Surface Temperature is near 30°C.  It will move through an area where there will be little vertical wind shear.  It is difficult for a typhoon or hurricane to continue to generate enough upper level divergence to stay extremely strong for a long period of time.  However, Typhoon Mangkhut could remain the equivalent of a Category 5 hurricane on the Saffir-Simpson Scale until it reaches northern Luzon.  Mangkhut will weaken when the center moves over northern Luzon.

Typhoon Mangkhut is moving south of a subtropical ridge over the Western North Pacific Ocean.  The ridge is steering Mangkhut toward the northwest and that general motion is forecast to continue.  On its anticipated track Typhoon Mangkhut will reach northern Luzon east of Tuguegarao in about 18 hours.  Mangkhut is capable of causing extensive catastrophic damage.  It will produce extremely strong winds over northern Luzon.  There will be a significant storm surge at the coast.  Locally heavy rain will cause flash floods.

Typhoon Mangkhut Strengthens Into Equivalent of Cat. 5 Hurricane

Typhoon Mangkhut strengthened into the equivalent of a Category 5 hurricane on the Saffir-Simpson Scale on Tuesday.  At 11:00 a.m. EDT on Tuesday the center of Typhoon Mangkhut was located at latitude 13.7°N and longitude 138.0°E which put it about 290 miles (470 km) north of Yap.  Mangkhut was moving toward the west 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 190 m.p.h. (305 km/h).  The minimum surface pressure was 915 mb.

Typhoon Mangkhut is strong and well organized.  It has a symmetrical circulation with a circular eye at the center.  A ring of strong thunderstorms surround the eye and the strongest winds are occurring in the ring of storms.  Several bands of showers and thunderstorms were revolving around the core of Typhoon Mangkhut.  Storms near the core were generating strong upper level divergence which was pumping large quantities of mass away from the typhoon in all directions.

Typhoon Mangkhut has a large circulation.  Winds to typhoon force extend out about 65 miles (105 km) from the center of circulation.  Winds to tropical storm force extend out about 210 miles (375 km) from the center.  The Hurricane Intensity Index (HII) for Typhoon Mangkhut is 35.0.  The Hurricane Size Index (HSI) is 22.1 and the Hurricane Wind Intensity Size Index (HWISI) is 57.1.  Typhoon Mangkhut is capable of causing extensive catastrophic damage.

Typhoon Mangkhut will be moving through an environment very favorable for powerful typhoons.  Mangkhut will be moving over water where the Sea Surface Temperature is near 30°C.  It will move through an area were the upper level winds are weak and there will be little vertical wind shear.  Typhoon Mangkhut could maintain its intensity for several more days unless eyewall replacement cycles cause fluctuations in the wind speed.

Typhoon Mangkhut is moving south a ridge of high pressure over the Western North Pacific Ocean.  The ridge will steer Mangkhut in a general west-northwesterly direction during the next few days.  On its anticipated track Typhoon Mangkhut could approach northern Luzon in about three days.  Mangkhut could be near Hong Kong in about five days.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Barijat was moving southeast of Hong Kong.  At 11:00 a.m. EDT on Tuesday the center of Tropical Storm Barijat was located at latitude 20.5°N and longitude 116.5°E which put it about 215 miles (345 km) southeast of Hong Kong.  Barijat was moving toward the west-southwest at 12 m.p.h. (19 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 1000 mb.

Typhoon Mangkhut Strengthens to Equivalent of a Major Hurricane

Typhoon Mangkhut strengthened into the equivalent of a major hurricane as it moved west of Guam on Monday.  At 11:00 p.m. EDT on Monday the center of Typhoon Mangkhut was located at latitude 14.0°N and longitude 140.6°E which put it about 230 miles (375 km) west of Guam.  Mangkhut was moving toward the west at 16 m.p.h. (26 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. (270 km/h).  The minimum surface pressure was 939 mb.  Typhoon Mangkhut was the equivalent of a Category 4 hurricane on the Saffir-Simpson Scale.

Typhoon Mangkhut intensified rapidly on Monday.  A circular eye was 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 Mangkhut.  Storms around the core were generating upper level divergence which was pumping mass away from the typhoon.

Winds to typhoon force extended out about 50 miles (80 km) from the center of circulation.  Winds to tropical storm force extended out about 210 miles (335 km) from the center.  The Hurricane Intensity Index (HII) for Typhoon Mangkhut was 28.2.  The Hurricane Size Index (HSI) was 18.9 and the Hurricane Wind Intensity Size Index (HWISI) was 47.1.

Typhoon Mangkhut will move through an environment capable of supporting very strong typhoons during the next two or three days.  Mangkhut 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 Mangkhut is likely to remain very strong for the next few days.  Eyewall replacement cycles could cause fluctuations in intensity.

Typhoon Mangkhut will move south of a ridge over the Western North Pacific Ocean.  The ridge will steer Mangkhut to the west during the next day or two.  Typhoon Mangkhut will move more toward the west-northwest later this week.  On its anticipated track Typhoon Mangkhut could be near northern Luzon in about four days.

Typhoon Mangkhut Brings Wind and Rain to the Marianas

Typhoon Mangkhut brought wind and rain to the Marianas on Sunday night.  At 11:00 p.m. EDT on Sunday the center of Typhoon Mangkhut was located at latitude 14.4°N and longitude 146.6°E which put it about 175 miles (285 km) east-northeast of Guam.  Mangkhut was moving toward the west at 19 m.p.h. (31 km/h).  The maximum sustained wind speed was 90 m.p.h. (145 km/h) and there were wind gusts to 115 m.p.h. (185 km/h).  The minimum surface pressure was 955 mb.  Typhoon Warnings were in effect for Saipan, Tinian, Rota and Guam.  The airport on Saipan was reporting sustained winds of 41 m.p.h. (66 km/h) and wind gusts to 61 m.p.h. (98 km/h).

Typhoon Mangkhut had a well organized circulation.  There was a circular eye at the center of Mangkhut.  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 Mangkhut.  Storms near the core were generating upper level divergence which was pumping mass away from the typhoon.

Winds to typhoon force extended out about 40 miles (65 km) from the center of circulation.  Winds to tropical storm force extended out about 150 miles (240 km) from the center.  The Hurricane Intensity Index (HII) for Typhoon Mangkhut was 13.9.  The Hurricane Size Index (HSI) was 13.5 and the Hurricane Wind Intensity Size Index was 27.4.  Typhoon Mangkhut was capable of causing regional significant damage.

Typhoon Mangkhut will move through an environment favorable for intensification.  Mangkhut will move over water where the Sea Surface Temperature is near 30°C.  An upper level ridge north of Mangkhut will cause easterly winds which will blow toward the top of the circulation.  Those winds will cause some vertical wind shear, but the shear will not be strong enough to prevent intensification.  Typhoon Mangkhut could intensify into the equivalent of a major hurricane later this week.

The ridge north of Typhoon Mangkhut will steer the typhoon in a westerly direction.  The core of Typhoon Mangkhut will move over the Marianas during the next few hours.  It will bring strong winds and it will drop locally heavy rain.  On its anticipated track Typhoon Mangkhut could be east of Luzon later this week.

Tropical Storm Mangkhut Causes Typhoon Watch for Marianas

Tropical Storm Mangkhut caused a Typhoon Watch to be issued for the Marianas on Saturday.  A Typhoon Watch was in effect for Guam, Rota, Saipan and Tinian.  At 5:00 p.m. EDT on Saturday the center of Tropical Storm Mangkhut was located at latitude 14.9°N and longitude 156.0°E which put it about 760 miles (1225 km) east of Guam.  Mangkhut was moving toward the west at 24 m.p.h. (39 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 983 mb.

The circulation of Tropical Storm Mangkhut became much better organized on Saturday despite its rapid westward movement.  A primary band of thunderstorms wrapped around the southern side of the center of circulation and an eye appeared to be forming.  Winds near the core of Mangkhut were generating upper level divergence which was pumping mass away from the tropical storm.  Several other bands of showers and thunderstorms were revolving around the core of Tropical Storm Mangkhut.  The strongest rainbands were in the western half of the circulation.  Bands in the eastern half of the tropical storm consisted primarily of showers and lower clouds.  An upper level ridge north of Mangkhut was producing easterly winds which were blowing toward the top of the circulation.  Those winds were causing vertical wind shear and they were probably the reason why the strongest rainbands were west of the center of circulation.

Tropical Storm Mangkhut will move through an environment favorable for intensification.  Mangkhut will move over water where the Sea Surface Temperature is near 30°C.  It will move into an area where the upper level winds are weaker and there will be less vertical wind shear.  Tropical Storm Mangkhut will intensify into a typhoon on Sunday and it could intensify rapidly once the inner core and eye are fully formed.

Tropical Storm Mangkhut will move south of a ridge over the Western North Pacific Ocean.  The ridge will steer Mangkhut in a general westerly direction during the next few days.  On its anticipated track Tropical Storm Mangkhut could reach the Marianas in about 36 hours.  It is likely to be a typhoon at that time.  Mangkhut could bring strong winds and locally heavy rain to Guam, Rota, Saipan and Tinian.

Large Typhoon Soulik Nears Ryukyu Islands, Cimaron Brushes Northern Marianas

Large Typhoon Soulik neared the Ryukyu Islands on Monday night, while Typhoon Cimaron brushed the Northern Mariana Islands.  At 11:00 p.m. EDT on Monday the center of Typhoon Soulik was located at latitude 28.0°N and longitude 131.7°E which put it about 160 miles (260 km) south-southeast of Yaku Shima, Japan.  Soulik was moving toward the northwest at 14 m.p.h. (22 km/h).  The maximum sustained wind speed was 115 m.p.h. (185 km/h) and there were wind gusts to 135 m.p.h. (215 km/h).  The minimum surface pressure was 952 mb.

A large circular eye with a diameter of 50 miles (80 km) developed at the center of Typhoon Soulik.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in the ring of storms.  Several bands of showers and thunderstorms were revolving around the core of Typhoon Soulik.  The strongest rainbands were occurring in the eastern half of the circulation.  Winds around the core Soulik were generating strong upper level divergence which was pumping mass away from the typhoon.

Typhoon Soulik has a large circulation.  Winds to typhoon force extend out about 70 miles (110 km) from the center of circulation.  Winds to tropical storm force extend out about 230 miles (370 km) from the center.  The Hurricane Intensity Index (HII) for Typhoon Soulik was 20.6.  The Hurricane Size Index (HSI) was 23.5 and the Hurricane Wind Intensity Size Index (HWISI) was 44.1.

The large symmetrical structure of Typhoon Soulik will allow it to maintain its intensity for a longer period than a smaller tropical cyclone.  Soulik will move through an environment during the next 24 to 36 hours that will support a strong typhoon.  It will move over water where the Sea Surface Temperature is near 28°C.  It will move through an environment where the vertical wind shear will not be too strong.

Typhoon Soulik will move around the western end of ridge centered north of Japan.  The ridge will steer Soulik toward the northwest for another 24 to 36 hours.  On its anticipated track Typhoon Soulik will move over the northern Ryukyu Islands on Tuesday.  Soulik could approach South Korea within 36 hours.

Typhoon Cimaron brushed the northernmost Mariana Islands on Monday.  At 11:00 p.m. EDT on Monday the center of Typhoon Cimaron was located at latitude 20.5°N and longitude 144.5°E which put it about 90 miles (145 km) north-northwest of Agrihan.  Cimaron was moving toward the west-northwest at 14 m.p.h. (22 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 978 mb.

Typhoon Cimaron is forecast to be near Iwo To in about 24 hours.  Cimaron could approach Honshu within 48 hours.  Upper level divergence from Typhoon Soulik is inhibiting the divergence on the western side of Cimaron.  The effects of Soulik will reduce the potential intensification of Typhoon Cimaron, but Cimaron could strengthen slowly during the next day or two.

Typhoon Soulik Strengthens Near Iwo To

Typhoon Soulik strengthened near Iwo To on Friday.  At 5:00 p.m. EDT on Friday the center of Typhoon Soulik was located at latitude 24.4°N and longitude 140.0°E which put it about 90 miles (145 km) west-southwest of Iwo To.  Soulik was moving toward the north at 6 m.p.h. (10 km/h).  The maximum sustained wind speed was 100 m.p.h. (160 km/h) and there were wind gusts to 125 m.p.h. (200 km/h).  The minimum surface pressure was 963 mb.

Typhoon Soulik strengthened quickly on Friday.  An eye appeared at the center of circulation on satellite imagery.  A ring of strong thunderstorms surrounded the eye and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of the circulation.  The strongest rainbands were occurring in the eastern half of Typhoon Soulik.  Storms around the core were generating strong upper level divergence which was pumping large quantities of mass away from the typhoon.  Winds to typhoon force extended out about 40 miles (65 km) from the center of circulation.  Winds to tropical storm force extended out about 150 miles (240 km) from the center.

Typhoon Soulik will move through an environment favorable for intensification during the next 48 hours.  Soulik will move over water where the Sea Surface Temperature is 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 Soulik will continue to intensify and it will become the equivalent of a major hurricane during the weekend.

Typhoon Soulik will be in an area where the winds at steering level are weak during next 12 to 24 hours.  Soulik is likely to move slowly northward during that time.  A subtropical ridge northeast of Typhoon Soulik is forecast to strengthen in a day or so.  When that happens, the ridge will steer Soulik in a general northwesterly direction.  On its anticipated track Typhoon Soulik will slowly away from Iwo To on Saturday.  Soulik will continue to produce gusty winds and to drop heavy rain over Iwo To until it moves away.  Typhoon Soulik will move in the general direction of Kyushu and the Ryukyu Islands during the next several days.

Tropical Storm Rumbia Makes Landfall Near Shanghai, Bebinca Hits Vietnam

Tropical Storm Rumbia made landfall on the east coast of China just south of Shanghai on Thursday, and Tropical Storm Babinca hit Vietnam.  At 5:00 p.m. EDT on Thursday the center of Tropical Storm Rumbia was located at latitude 30.5°N and longitude 121.0°E which put it about 60 miles (95 km) southwest of Shanghai, China.  Rumbia 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 987 mb.

Tropical Storm Rumbia strengthened before it made landfall.  Thunderstorms developed near the center of circulation and a band wrapped around the center.  The circulation became more circular and storms near the center began to generate upper level divergence.  In the western half off the circulation where the winds were blowing toward the land, increased friction enhanced rising motion and heavier rain fell.

Tropical Storm Rumbia caused some gusty winds near the coast, but the greater risks were the locally heavy rain and the potential for floods.  Tropical Storm Rumbia is forecast to move slightly north of due west as it moves inland over eastern China.  Rumbia will drop locally heavy rain over the area around Shanghai, and over parts Zhejiang, Jiangsu and Anhui provinces.  Some of those regions have received heavy rain from previous storms and the potential for serious flooding exists.

Tropical Storm Bebinca made landfall on the coast of Vietnam on Thursday.  At 5:00 p.m. EDT on Thursday the center of Tropical Storm Bebinca was located at latitude 19.9°N and longitude 106.3°E which put it about 70 miles (110 km) southeast of Ninh Binh, Vietnam.  Bebinca was moving toward the west-southwest 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 979 mb.

Tropical Storm Bebinca also strengthened before it made landfall.  An eye started to form at the center of circulation and Bebinca was on the threshold of becoming a typhoon when it made landfall.  Tropical Storm Bebinca produced gusty winds and a storm surge near the coast.  However, the greatest risks are locally heavy rain and the potential for floods.  Tropical Storm Bebinca is forecast to move in a general westerly direction.  Bebinca will drop locally heavy rain over parts of Vietnam, northern Laos and extreme northern Thailand.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Soulik moved quickly toward Iwo To and strengthened.  At 5:00 p.m. EDT on Thursday the center of Tropical Storm Soulik was located at latitude 20.9°N and longitude 141.3°E which put it about 315 miles (510 km) south of Iwo To.  Soulik was moving toward the north at 20 m.p.h. (32 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 981 mb.

Tropical Storm Rumbia Nears Shanghai, Bebinca Strengthens East of Vietnam

Tropical Storm Rumbia moved closer to Shanghai on Wednesday, while Tropical Storm Bebinca strengthened east of Vietnam and Tropical Storm Soulik formed west of Guam.  At 11:00 p.m. EDT on Wednesday the center of Tropical Storm Rumbia was located at latitude 30.1°N and longitude 124.2°E which put it about 160 miles (260 km) southeast of Shanghai, China.  Rumbia was moving toward the west-northwest at 7 m.p.h. (11 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 999 mb.

Tropical Storm Rumbia has about 12 to 18 hours before it makes landfall near Shanghai.  It will move through an environment somewhat favorable for intensification.  Rumbia will move over water where the Sea Surface Temperature is near 28°C.  The circulation of Rumbia is broad.  There is a distinct center of circulation, but there are few thunderstorms close to the center.  Most of the stronger thunderstorms were occurring in rainbands revolving around the center of Rumbia.  The broad circulation will limit the potential for intensification, but Tropical Storm Rumbia could get stronger before it reaches the east coast of China on Thursday.

Tropical Storm Bebinca strengthened on Wednesday while it moved south of China.  At 11:00 p.m. EDT on Wednesday the center of Tropical Storm Bebinca was located at latitude 19.9°N and longitude 108.2°E which put it about 125 miles (200 km) east-southeast of Hai Phong, Vietnam.  Bebinca was moving toward the west-southwest at 15 m.p.h. (24 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 980 mb.

Tropical Storm Bebinca intensified quickly on Wednesday after it moved west of Hainan Island.  A primary rainband wrapped around the center of circulation and an eye appeared to be forming.  Several bands of showers and thunderstorms were revolving around the core of Bebinca.  Tropical Storm Bebinca has about 18 hours before it reaches the coast of Vietnam.  It will move through an environment favorable for intensification.  Bebinca will move over water where the Sea Surface Temperature is near 29°C.  It will move through an area where the upper level winds are weak and there is little vertical wind shear.  Bebinca could strengthen into a typhoon before it reaches Vietnam.

Tropical Storm Bebinca could make landfall on the coast of  Vietnam between Hai Phong and Vinh within 24 hours.  It could be a typhoon when it makes landfall.  Bebinca will bring strong winds capable of causing damage.  it could generate a storm surge of 6 to 9 feet (2 to 3 meters) at the coast.  Bebinca will drop heavy rain over parts of Vietnam and it could cause serious flooding.

Tropical Storm Soulik formed west of Guam on Wednesday.  At 11:00 p.m. EDT on Wednesday the center of Tropical Storm Soulik was located at latitude 15.9°N and longitude 142.7°E which put it about 165 miles (265 km) northwest of Guam.  Soulik was moving toward the north-northwest at 20 m.p.h. (32 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 999 mb.

Tropical Storm Soulik will move through an environment favorable for intensification.  Soulik will move over water where the Sea Surface Temperature is near 29°C.  It will move east of an upper level low that will produce southerly winds.  Those winds will move blow toward the top of the circulation and they will cause some vertical wind shear, but they will not be strong enough to prevent intensification.  Soulik could strengthen into a typhoon within 48 hours.  The upper low will pull Tropical Storm Soulik toward Iwo To.

Tropical Storm Leepi Approaches Kyushu

Tropical Storm Leepi approached Kyushu late on Monday.  At 11:00 p.m. EDT on Monday the center of Tropical Storm Leepi was located at latitude 29.8°N and longitude 135.3°E which put it about 335 miles (545 km) east-southeast of Kagoshima, Japan.  Leepi was moving toward the northwest at 17 m.p.h. (28 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 983 mb.

The circulation of Tropical Storm Leepi became much better organized on Monday.  A large circular clear area formed at the center of circulation, which represented the formation of an eye.  A primary band of showers and thunderstorms wrapped most of the way around the formative eye and the strongest winds were occurring in that band of storms.  Several bands of showers and thunderstorms in the eastern half of the circulation were revolving around the core of Tropical Storm Leepi.  Bands northwest of the center consisted mostly of showers and lower clouds.  Winds to tropical storm force extend out about 110 miles (170 km) from the center of circulation.  Storms around the center of Tropical Storm Leepi were generating upper level divergence that was pumping mass away from the tropical storm.

Tropical Storm Leepi will move through an environment that will become less favorable on Tuesday.  Leepi will move over water where the Sea Surface Temperature is near 28°C which means there will be enough energy to support a strong tropical storm.  However, an upper level ridge northwest of Japan will produce northeasterly winds which will cause significant vertical wind shear.  The wind shear will cause Tropical Storm Leepi to start to weaken when it nears Japan.

The ridge northwest of Japan will steer Tropical Storm Leepi toward the northwest on Tuesday.  On its anticipated track the center of Tropical Storm Leepi will reach southeastern Kyushu in about 18 hours.  Leepi will bring gusty winds and locally heavy rain to Kyushu late on Tuesday.  The locally heavy rain could create the potential for flash floods.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Bebinca meandered southwest of Hong Kong and Tropical Storm Hector move westward across the International Date Line.  At 11:00 p.m. EDT on Monday the center of Tropical Storm Bebinca was located at latitude 21.1°N and longitude 113.8°E which put it about 100 miles (160 km) south-southwest of Hong Kong.  Bebinca was moving toward the north-northeast at 5 m.p.h. (8 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. (95km/h).  The minimum surface pressure was 989 mb.

At 11:00 p.m. EDT on Monday the center of Tropical Storm Hector was located at latitude 26.2°N and longitude 176.2°E which put it about 760 miles (1225 km) east-northeast of Wake Island.  Hector was moving toward the west at 18 m.p.h. (29 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 1003 mb.
