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.

Typhoon Kajiki Hits Northern Vietnam

Typhoon Kajiki hit the coast of northern Vietnam near Vinh early on Monday.  At 5:00 a.m. EDT on Monday the center of Typhoon Kajiki was located at latitude 18.6°N and longitude 105.7°E which put the center about 10 miles (15 km) southeast of Vinh, Vietnam.  Kajiki was moving toward the west at 13 m.p.h. (21 km/h).  The maximum sustained wind speed was 105 m.p.h. (165 km/h) and there were wind gusts to 125 m.p.h. (200 km/h).  The minimum surface pressure was 967 mb.

The center of Typhoon Kajiki hit the coast of northern Vietnam near Vinh early on Monday.  The circulation around Typhoon Kajiki was relatively small.  Winds to typhoon force extended out 40 miles (65 km/h) from the center of Kajiki’s circulation.  Winds to tropical storm force extended out 90 miles (145 km) from the center of Typhoon Kajiki.

The Hurricane Intensity Index (HII) for Typhoon Kajiki is 17.8.  The Hurricane Size Index (HSI) is 11.9 and the Hurricane Wind Intensity Size Index (HWISI) is 29.7.  Typhoon Kajiki is similar in size and intensity to Hurricane Sally when Sally hit South Alabama in 2020.

Typhoon Kajiki will move around the southern side of a high pressure system over China.  The high pressure system will steer Kajiki toward the west-northwest during the next 24 hours.  On its anticipated track, Typhoon Kajiki will move inland over northern Vietnam.  Kajiki will move over northern Laos in 12 to 18 hours.

Typhoon Kajiki will bring strong winds and locally heavy rain to northern Vietnam.  Heavy rain is likely to cause flash floods in some locations.  Kajiki will weaken steadily as it moves inland, but it could also drop heavy rain over parts of northern Laos and northern Thailand.

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.
