Typhoon Bualoi Brings Wind and Rain to Vietnam

Typhoon Bualoi brought wind and rain to northern Vietnam on Sunday.  At 11:00 a.m. EDT on Sunday the center of Typhoon Bualoi was located at latitude 18.0°N and longitude 106.5°E which put the center about 25 miles (40 km) southeast of Ky Anh, Vietnam.  Bualoi was moving toward the northwest at 14 m.p.h. (22 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 977 mb.

The center of Typhoon Bualoi made landfall on the coast of Vietnam southeast of Ky Anh on Sunday.  An eye formed that the center of Bualoi’s circulation just before it made landfall.  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 center of Typhoon Bualoi.

The strongest winds were occurring in the parts of Typhoon Bualoi that were still over the South China Sea.  Winds to typhoon force extended out 45 miles (75 km) in the northern side of Bualoi’s circulation.  Winds to tropical storm force extended out 145 miles (235 km) from the center of Typhoon Bualoi.

Typhoon Bualoi will move around the southern side of a high pressure system over China.  The high pressure system will steer Bualoi toward the west-northwest during the next 24 hours.  On its anticipated track, Typhoon Bualoi will move inland over northern Vietnam.  Bualoi will weaken steadily as it moves farther inland.

Typhoon Bualoi will bring strong winds and locally heavy rain to parts of northern Vietnam.  Heavy rain is likely to cause flash floods in some locations.  Bualoi could cause a storm surge of up to 10 feet (3 meters) along portions of the coast.  Bualoi could also drop heavy rain over parts of northern Laos on Monday.

Elsewhere over the Western North Pacific Ocean, Typhoon Neoguri  was racing toward the northeast.  At 11:00 a.m. EDT on Sunday the center of Typhoon Neoguri was located at latitude 38.9°N and longitude 168.6°E which put the center about 1320 miles (2120 km) north of Wake Island.  Neoguri was moving toward the northeast at 35 m.p.h. (55 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 953 mb.

Typhoon Bualoi Approaches Northern Vietnam

Typhoon Bualoi was approaching the coast of northern Vietnam on Saturday evening.  At 11:00 p.m. EDT on Saturday the center of Typhoon Bualoi was located at latitude 16.7°N and longitude 108.8°E which put the center about 80 miles (130 km) east-northeast of Da Nang Vietnam.  Bualoi was moving toward the west-northwest at 15 m.p.h. (24 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 982 mb.

Typhoon Bualoi was maintaining its intensity as it approached the coast of northern Vietnam on Saturday evening.  Thunderstorms continued to form near the center of Bualoi’s circulation.  Bands of showers and thunderstorms were revolving around the center of Typhoon Bualoi.  Storms near the center of Bualoi generated upper level divergence that pumped mass away to the south and west of the typhoon.   The removal of mass in the upper levels were balanced by the inflow of mass in the lower levels of the atmosphere.  The balance of outflow and inflow caused the surface pressure to remain nearly constant.

The strongest winds were occurring in the northern side of Typhoon Bualoi.  Winds to typhoon force extended out 35 miles (55 km) in the northern side of Bualoi’s circulation.  Winds to tropical storm force extended out 160 miles (260 km) from the center of Typhoon Bualoi.

Typhoon Bualoi will move through an environment somewhat favorable for intensification during the next few hours.  Bualoi will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the southern part of an upper level ridge over China.  The upper level ridge will produce easterly winds that will blow toward the top of Bualoi’s circulation.  Those winds will cause moderate vertical wind shear.  The vertical wind shear will inhibit intensification, but the moderate shear may not be enough to prevent intensification. Typhoon Bualoi could intensify before it reaches the coast of northern Vietnam.

Typhoon Bualoi will move around the southern side of a high pressure system over China.  The high pressure system will steer Bualoi toward the west-northwest during the next 24 hours.  On its anticipated track, the center of Typhoon Bualoi will make landfall on the coast of northern Vietnam in a few hours.  The center of Bualoi Is likely to make landfall between Hue and Vinh.

Typhoon Bualoi will bring strong winds and locally heavy rain to parts of northern Vietnam.  Heavy rain is likely to cause flash floods in some locations.  Bualoi could cause a storm surge of up to 10 feet (3 meters) along portions of the coast.

Elsewhere over the Western North Pacific Ocean, Typhoon Neoguri intensified far to the west of Japan.  At 11:00 p.m. EDT on Saturday the center of Typhoon Neoguri was located at latitude 35.2°N and longitude 163.6°E which put the center about 1065 miles (1720 km) north-northwest of Wake, Island.  Neoguri was moving toward the northeast at 22 m.p.h. (35 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 957 mb.

Bualoi Strengthens to Typhoon over South China Sea

Former Tropical Storm Bualoi strengthened to a typhoon as it moved over the South China Sea on Friday evening.  At 11:00 p.m. EDT on Friday the center of Typhoon Bualoi was located at latitude 15.1°N and longitude 114.2°E which put the center about 400 miles (645 km) east of Da Nang Vietnam.  Bualoi was moving toward the west-northwest at 28 m.p.h. (45 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 982 mb.

Former Tropical Storm Bualoi strengthened to a typhoon on Friday evening.  Even though Bualoi strengthened to a typhoon, the distribution of thunderstorms was asymmetrical.  Thunderstorms were occurring in bands in the eastern and southern parts of Typhoon Bualoi.  Bands in the western and northern parts of Bualoi consisted primarily of showers and lower clouds.  Storms near the center of Bualoi generated upper level divergence that pumped mass away to the south and west of the typhoon.  The removal of mass caused the surface pressure to decrease.

The circulation around Typhoon Bualoi was relatively small.  Winds to typhoon force extended out 35 miles (55 km) from the center of Bualoi’s circulation.  Winds to tropical storm force extended out 105 miles (165 km) from the center of Typhoon Bualoi.

Typhoon Bualoi will move through an environment somewhat favorable for intensification during the next 24 hours.  Bualoi will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the southern part of an upper level ridge over China.  The upper level ridge will produce easterly winds that will blow toward the top of Bualoi’s circulation.  Those winds will cause moderate vertical wind shear.  The vertical wind shear will inhibit intensification, but the moderate shear may not be enough to prevent intensification.  Typhoon Bualoi could intensify during the next 24 hours.

Typhoon Bualoi will move around the southern side of a high pressure system over China.  The high pressure system will steer Bualoi toward the north-northwest during the next 24 hours.  On its anticipated track, Typhoon Bualoi will move toward the coast of northern Vietnam.  Bualoi could reach the coast in 36 hours.

Typhoon Bualoi will bring strong winds and locally heavy rain to parts of northern Vietnam.  Heavy rain is likely to cause flash floods in some location.  Bualoi could cause a storm surge of up to 10 feet (3 meters) along portions of the coast.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Neoguri was still meandering far to the east of Japan.  At 11:00 p.m. EDT on Friday the center of Tropical Storm Neoguri was located at latitude 31.8°N and longitude 156.3°E which put the center about 925 miles (1490 km) east of Tokyo, Japan.  Neoguri was moving toward the east at 11 m.p.h. (17 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 Bualoi Brings Wind and Rain to Central Philippines

Tropical Storm Bualoi brought wind and rain to the central Philippines on Thursday.  At 5:00 p.m. EDT on Thursday the center of Tropical Storm Bualoi was located at latitude 12.4°N and longitude 124.6°E which put the center about 5 miles (10 km) west of Catarman, Philippines.  Bualoi was moving toward the west-northwest at 13 m.p.h. (21 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. (13 km/h).  The minimum surface pressure was 993 mb.

Tropical Storm Bualoi brought wind and rain to the central Philippines on Thursday.  The strongest winds and heaviest rain were occurring in Samar.  Bualoi was also bringing wind and rain to southeastern Luzon and Masbate.

Tropical Storm Bualoi strengthened as it approached the central Philippines.  More thunderstorms formed near the center of Bualoi’s circulation.  Bands of showers and thunderstorms were revolving around the center of Tropical Storm Bualoi.  Storms near the center of Bualoi generated upper level divergence that pumped mass away from the tropical storm.  The removal of mass caused the surface pressure to decrease.

The distribution of wind speeds in Tropical Storm Bualoi became more symmetrical on Thursday.  Winds to tropical storm force extended out 105 miles (165 km) from the center of Bualoi’s circulation.

Tropical Storm Bualoi will move through an environment somewhat favorable for intensification during the next 24 hours.  Bualoi will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the southern part of an upper level ridge over the Western North Pacific Ocean.  The upper level ridge will produce easterly winds that will blow toward the top of Bualoi’s circulation.  Those winds will cause some vertical wind shear.  The vertical wind shear will inhibit intensification.  Even though Tropical Storm Bualoi will move through a somewhat favorable environment, the center of Bualoi will be over land at times as it moves across the central Philippines.  The times when the center of Tropical Storm Bualoi is over land will also inhibit intensification.

Tropical Storm Bualoi will move around the southern side of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Bualoi toward the west-northwest during the next 24 hours.  On its anticipated track, the center of Tropical Storm Bualoi will move across the Sibuyan Sea.  Bualoi will move over the South China Sea during the weekend.

Tropical Storm Bualoi will bring strong winds and heavy rain to the central Philippines.  The strongest winds and heaviest rain will occur in southern Luzon, Masbate, Sibuyan Island, Tablas Island, Burias Island, Marinduque, and Mindoro.  Heavy rain is likely to cause flash floods in some locations.  Bualoi could also cause a storm surge of up to 7 feet (2 meters) along the coasts where the wind blows the water toward the shore.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Neoguri continued to meander far to the east of Japan.  At 5:00 p.m. EDT on Thursday the center of Tropical Storm Neoguri was located at latitude 32.0°N and longitude 154.1°E which put the center about 855 miles (1380 km) east of Tokyo, Japan.  Neoguri was moving toward the west-southwest at 6 m.p.h. (10 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 982 mb.

Typhoon Ragasa Makes Landfall in Southern China

Typhoon Ragasa made landfall on the coast of southern China east of Yangjiang on Wednesday morning.  At 11:00 a.m. EDT on Wednesday the center of Typhoon Ragasa was located at latitude 21.9°N and longitude 110.5°E which put the center about 30 miles (50 km) northeast of Yangjiang, China.  Ragasa was moving toward the west at 16 m.p.h. (26 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 96 mb.

The center of Typhoon Ragasa made landfall on the coast of southern China east of Yangjiang on Wednesday morning.  Ragasa was a large and powerful typhoon at the time of landfall.  Winds to typhoon force extended out 60 miles (95 km) from the center of Ragasa’s circulation.  Winds to tropical storm force extended out 190 miles (305 km) from the center of Typhoon Ragasa.

The Hurricane Intensity Index (HII) for Typhoon Ragasa was 13.9.  The Hurricane Size Index (HSI) was 20.8 and the Hurricane Wind Intensity Size Index (HWISI) was 34.7.

Typhoon Ragasa will move around the southern side of a high pressure system over China.  The high pressure system will steer Ragasa toward the west during the next 24 hours.  On its anticipated track, the center of Typhoon Ragasa will move westward near the coast of southern China.  Ragasa will move over northern Vietnam on Thursday.

Typhoon Ragasa will bring strong winds and heavy rain to Guangxi, western Guangdong, and northern Hainan.  Heavy rain is likely to cause floods in some locations.  Typhoon Ragasa could cause a storm surge of up to 10 feet (3 meters) along portions of the coast.  Ragasa could also drop heavy rain on parts of northern Vietnam and northern Laos.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Bualoi was strengthening east of the Philippines and Tropical Storm Neoguri was spinning far to the east of Japan.

At 11:00 a.m. EDT on Wednesday the center of Tropical Storm Bualoi was located at latitude 10.6°N and longitude 130.5°E which put the center about 375 miles (605 km) east-southeast of Tacloban, Philippines.  Bualoi was moving toward the west-northwest at 11 m.p.h. (17 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 994 mb.

At 11:00 a.m. EDT on Wednesday the center of Tropical Storm Neoguri was located at latitude 31.2°N and longitude 156.8°E which put the center about 1060 miles (1710 km) east-southeast of Tokyo, Japan.  Neoguri was moving toward the east-northeast at 16 m.p.h. (26 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 980 mb.

Typhoon Ragasa Brings Wind and Rain to Hong Kong

Typhoon Ragasa brought wind and rain to Hong Kong on Tuesday night.  At 11:00 p.m. EDT on Tuesday the center of Typhoon Ragasa was located at latitude 21.3°N and longitude 113.2°E which put the center about 80 miles (130 km) south-southwest of Hong Kong.  Ragasa 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 155 m.p.h. (250 km/h).  The minimum surface pressure was 944 mb.

The center of Typhoon Ragasa passed south of Hong Kong on Tuesday night.  A weather station at the airport in Hong Kong (VHHH) reported a sustained wind speed of 47 kt (54 m.p.h. or 87 km/h) and a wind gust of 66 kt (76 m.p.h. or 122 km/h).

The inner end of a rainband wrapped around the existing eye and eyewall in Typhoon Ragasa as it was passing south of Hong Kong.  A second outer eyewall appeared to be developing.  The formation of concentric eyewalls could start another eyewall replacement cycle.  Bands of showers and thunderstorms were revolving around the core of Typhoon Ragasa.  Storms near the core generated upper level divergence that pumped mass away from the typhoon.

The circulation around Typhoon Ragasa was large.  Winds to typhoon force extended out 60 miles (95 km) from the center of Ragasa’s circulation.  Winds to tropical storm force extended out 190 miles (305 km) from the center of Typhoon Ragasa.

The Hurricane Intensity Index (HII) for Typhoon Ragasa is 25.1.  The Hurricane Size Index (HSI) is 20.8 and the Hurricane Wind Intensity Size Index (HWISI) is 45.9.  Typhoon Ragasa is similar in intensity to Hurricane Harvey when Harvey hit Texas in 2017.  Ragasa is larger than Harvey was.

Typhoon Ragasa will move through an environment that will be favorable for a powerful typhoon during the next few hours.  Ragasa 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.  Even though Typhoon Ragasa will move through a favorable environment, another eyewall replacement cycle would cause Ragasa to weaken.

Typhoon Ragasa will move around the southern side of a high pressure system over China.  The high pressure system will steer Ragasa toward the west during the next 24 hours.  On its anticipated track, the center of Typhoon Ragasa will make landfall on the coast of southern China west of Macau in 12 hours.

Typhoon Ragasa will bring strong winds and heavy rain to Guangxi and to western Guangdong.  Heavy rain is likely to cause floods in some locations.  Typhoon Ragasa could cause a storm surge of up to 13 feet (4 meters) along portions of the coast.  Ragasa could also drop heavy rain over northern parts of Vietnam and Laos.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Bualoi formed east of the Philippines and former Typhoon Neoguri weakened to a tropical storm far to the east of Japan.

At 11:00 p.m. EDT on Tuesday the center of Tropical Storm Bualoi was located at latitude 9.5°N and longitude 133.4°E which put the center about 535 miles (865 km) east of Surigao, Philippines.  Bualoi was moving toward the west-southwest at 11 m.p.h. (17 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 1002 mb.

At 11:00 p.m. EDT on Tuesday the center of Tropical Storm Neoguri was located at latitude 30.6°N and longitude 154.6°E which put the center about 910 miles (1465 km) east-southeast of Tokyo, Japan.  Neoguri was moving toward the east at 6 m.p.h. (10 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 978 mb.

Typhoon Usagi Hits Northern Luzon

Typhoon Usagi hit northern Luzon on Wednesday night.  At 10:00 p.m. EST on Wednesday the center of Typhoon Usagi was located at latitude 17.6°N and longitude 122.7°E which put the center about 1205 miles (195 km) southeast of Aparri, Philippines.  Usagi was moving toward the northwest at 14 m.p.h. (22 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 915 mb.

Typhoon Usagi rapidly intensified to the equivalent of a Category 4 hurricane on the Saffir-Simpson Scale east of Luzon on Wednesday.  A small circular eye with a diameter of 5 miles (8 km) was at the center of Usagi’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 revolved around the core of Typhoon Usagi.  Storms near the core of Usagi generated strong upper level divergence that pumped large quantities of mass away from the typhoon in all directions.  The removal of large amounts of mass caused the surface pressure to decrease rapidly.  The inner end of a rainband wrapped around the existing eye and eyewall at the center of Usagi’s circulation during Wednesday evening and concentric eyewalls could be forming.

The circulation around Typhoon Usagi was small.  Winds to typhoon force extended out 30 miles (50 km) from the center of Usagi’s circulation.  Winds to tropical storm force extended out 85 miles (135 km) from the center of Typhoon Usagi.

The Hurricane Intensity Index (HII) for Typhoon Usagi was 31.6.  The Hurricane Size Index (HSI) was 9.4 and the Hurricane Wind Intensity Size Index (HWISI) was 41.0 . Typhoon Usagi was similar in size to Hurricane Ida when Ida hit Louisiana in 2021.  Usagi was not as big as Ida was.

Typhoon Usagi will move around the southern side of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Usagi toward the northwest during the next 24 hours.  On its anticipated track, the center of Typhoon Usagi will move across northeast Luzon during the next few hours.

Typhoon Usagi will bring strong winds and heavy rain to northern Luzon.  Heavy rain could cause flash floods and mudslides in some locations.  Usagi could cause a storm surge of up to 13 feet ( 4 meters) on the coast of northeastern Luzon.  The area likely to be hit by Usagi was just hit by Typhoon Toraji a few days ago.  Typhoon Usagi will complicate recovery efforts in Luzon.

Elsewhere over the Western North Pacific Ocean, former Tropical Storm Toraji weakened to a tropical depression south of Hong Kong, and Tropical Storm Man-yi was moved north of Yap.

At 10:00 p.m. EST on Wednesday the center of Tropical Depression Toraji was located at latitude 21.0°N and longitude 113.9°E which put the center about 90 miles (145 km) south of Hong Kong.  Toraji was moving toward the west-southwest at 5 m.p.h. (8 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 1005 mb.

At 10:00 p.m. EST on Wednesday the center of Tropical Storm Man-yi was located at latitude 11.1°N and longitude 137.0°E which put the center about 120 miles (195 km) north of Yap. Man-yi was moving toward the west-southwest at 20 m.p.h. (32 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 1000 mb.

Typhoon Usagi Rapidly Intensifies to Equivalent of a Major Hurricane

Typhoon Usagi rapidly intensified to the equivalent of a major hurricane over the Western North Pacific Ocean east of Luzon on Wednesday.  At 10:00 a.m. EST on Wednesday the center of Typhoon Usagi was located at latitude 16.5°N and longitude 124.8°E which put the center about 485 miles (780 km) east-southeast of Aparri, Philippines.  Usagi was moving toward the west-northwest at 15 m.p.h. (24 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 949 mb.

Typhoon Usagi rapidly intensified to the equivalent of a Category 4 hurricane on the Saffir-Simpson Scale east of Luzon on Wednesday.  A small circular eye with a diameter of 5 miles (8 km) formed at the center of Usagi’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 revolved around the core of Typhoon Usagi.  Storms near the core of Usagi generated strong upper level divergence that pumped large quantities of mass away from the typhoon in all directions.  The removal of large amounts of mass caused the surface pressure to decrease rapidly.

The circulation around Typhoon Usagi was small.  Winds to typhoon force extended out 30 miles (50 km) from the center of Usagi’s circulation.  Winds to tropical storm force extended out 80 miles (130 km) from the center of Typhoon Usagi.

The Hurricane Intensity Index (HII) for Typhoon Usagi was 25.1.  The Hurricane Size Index (HSI) was 9.4 and the Hurricane Wind Intensity Size Index (HWISI) was 34.5.  Typhoon Usagi was similar in size to Hurricane Harvey when Harvey hit Texas in 2017.  Usagi was not as big as Harvey was.

Typhoon Usagi will move through an environment favorable for intensification during the next 24 hours.  Usagi will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the axis of an upper level ridge over the Western North Pacific Ocean.  The upper level winds are weak near the axis of the ridge and there will be little vertical wind shear.  Typhoon Usagi could continue to intensify during the next 24 hours.  However, since the core of Usagi’s circulation is so small, the inner end of a rainband could wrap around the core.  If concentric eyewalls form, an eyewall replacement cycle would halt the intensification of Typhoon Usagi.

Typhoon Usagi will move around the southern side of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Usagi toward the west-northwest during the next 24 hours.  On its anticipated track, the center of Typhoon Usagi will move near northeast Luzon in 18 hours.

Typhoon Usagi will bring strong winds and heavy rain to northern Luzon.  Heavy rain could cause flash floods and mudslides in some locations.  Usagi could cause a storm surge of up to 13 feet ( 4 meters) on the coast of northeastern Luzon.  The area likely to be hit by Usagi was just hit by Typhoon Toraji a few days ago.  Typhoon Usagi will complicate recovery efforts in Luzon.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Toraji was approaching the coast of China east of Hong Kong, and Tropical Storm Man-yi was moving away from the Marianas.

At 10:00 a.m. EST on Wednesday the center of Tropical Storm Toraji was located at latitude 21.9°N and longitude 114.9°E which put the center about 65 miles (105 km) east-southeast of Hong Kong.  Toraji was moving toward the north at 14 m.p.h. (22 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 995 mb.

At 10:00 a.m. EST on Wednesday the center of Tropical Storm Man-yi was located at latitude 11.7°N and longitude 140.4°E which put the center about 280 miles (450 km) west-southwest of Guam.  Man-yi was moving toward the west-southwest at 16 m.p.h. (26 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 1002 mb.

Tropical Storm Man-yi Brings Gusty Winds to Guam

Tropical Storm Man-yi brought gusty winds to Guam on Tuesday.  At 4:00 p.m. EST on Tuesday the center of Tropical Storm Man-yi was located at latitude 12.5°N and longitude 144.4°E which put the center about 40 miles (65 km) southeast of Guam.  Man-yi was moving toward the southwest 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 994 mb.

Tropical Storm Warnings were in effect for Guam, Rota, Tinian, and Saipan.

Tropical Storm Man-yi brought gusty wind to Guam and the Marianas on Tuesday.  A weather station at the Guam International Airport reported a sustained wind speed of 30 m.p.h. (50 km/h) and a wind gust of 48 m.p.h. (77 km/h) on Tuesday.

The circulation around Tropical Storm Man-yi was somewhat disorganized.  There were not many thunderstorms near the center of Man-yi’s circulation.  Thunderstorms were occurring in bands in the southern side of the center of Tropical Storm Man-yi.  Bands in the northern side of Man-yi’s circulation consisted primarily of showers and lower clouds.

The circulation around Tropical Storm Man-yi was small.  Winds to tropical storm force extended out 85 miles (135 km) from the center of Man-yi’s circulation.

Tropical Storm Man-yi will move through an environment somewhat favorable for intensification during the next 24 hours.  Man-yi will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the southern side of an upper level ridge over the Western North Pacific Ocean.  The upper level ridge will produce easterly winds that will blow toward the top of Man-yi’s circulation.  Those winds will cause some vertical wind shear. The wind shear will inhibit intensification, but the shear may not be enough to prevent intensification. Tropical Storm Man-yi could intensify during the next 24 hours.

Tropical Storm Man-yi will move around the southern side of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Man-yi toward the west during the next 24 hours.  On its anticipated track, Tropical Storm Man-yi will move away from the Marianas.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Usagi strengthened east of the Philippines, Tropical Depression Yinxing moved inland over Vietnam, and Tropical Storm Toraji was spinning over the South China Sea southeast of Hong Kong.

(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 987 mb.

At 10:00 a.m. EST on Tuesday the center of Tropical Depression Yinxing was located at latitude 14.0°N and longitude 108.2°E which put the center about 145 miles (235 km) south of Da Nang, Vietnam.  Yinxing was moving toward the west at 9 m.p.h. (15 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 1004 mb.

At 4:00 p.m. EST on Tuesday the center of Tropical Storm Toraji was located at latitude 20.1°N and longitude 116.8°E which put the center about 245 miles (395 km) southeast of Hong Kong.  Toraji was moving toward the west-northwest at 5 m.p.h. (8 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 997 mb.

Tropical Storm Usagi Forms East of the Philippines

Tropical Storm Usagi formed over the Western North Pacific Ocean east of the Philippines on Monday.  At 4:00 p.m. EST on Monday the center of Tropical Storm Usagi was located at latitude 13.0°N and longitude 134.2°E which put the center about 945 miles (1525 km) east of Manila, Philippines.  Usagi was moving toward the west at 17 m.p.h. (28 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 991 mb.

Another tropical storm formed east of the Philippines on Monday.  Former Tropical Depression Twentyseven-W strengthened and the Japan Meteorological Agency designated the system as Tropical Storm Usagi.  More thunderstorms formed near the center of Usagi’s circulation.  However, the distribution of thunderstorms in Tropical Storm Usagi was asymmetrical.  Many of the thunderstorms were occurring in bands in the western half of Usagi’s circulation.  Bands in the eastern half of Tropical Storm Usagi consisted primarily of showers and lower clouds.  Storms near the center of Usagi generated upper level divergence that pumped mass away to the west of the tropical storm.

The circulation around Tropical Storm Usagi was small.  Winds to tropical storm force extended out 50 miles (80 km) from the center of Usagi’s circulation.

Tropical Storm Usagi will move through an environment favorable for intensification during the next 24 hours.  Usagi will move over water where the Sea Surface Temperatures are near 30°C.   It will move under the southern side of an upper level ridge over the Western North Pacific Ocean.  The upper level ridge will produce easterly winds that will blow toward the top of Usagi’s circulation.  Those winds will cause some vertical wind shear.  The wind shear will inhibit intensification, but the shear will not be enough to prevent intensification.  Tropical Storm Usagi will intensify during the next 24 hours.  Usagi could strengthen to a typhoon on Tuesday.

Tropical Storm Usagi will move around the southern side of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Usagi toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Usagi will move toward the Philippines.

Elsewhere over the Western North Pacific Ocean, former Typhoon Toraji weakened as it moved away from the Philippines, Tropical Storm Yinxing approached the coast of Vietnam, Tropical Storm Watches were issued in the Marianas for Tropical Storm Man-yi.

At 4:00 p.m. EST on Monday the center of Tropical Storm Toraji was located at latitude 18.5°N and longitude 118.7°E which put the center about 420 miles (675 km) southeast of Hong Kong.  Toraji was moving toward the west-northwest at 10 m.p.h. (16 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 985 mb.

At 4:00 p.m. EST on Monday the center of Tropical Storm Yinxing was located at latitude 14.6°N and longitude 109.6°E which put the center about 130 miles (210 km) southeast of Da Nang, Vietnam.  Yinxing was moving toward the south-southwest 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 999 mb.

At 4:00 p.m. EST on Monday the center of Tropical Storm Man-yi was located at latitude 14.0°N and longitude 150.5°E which put the center about 430 miles (695 km) east of Guam.  Man-yi was moving toward the west-southwest at 8 m.p.h. (13 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 992 mb.

Tropical Storm Watches were in effect for Guam, Rota, Tinian and Saipan.
