Leave a reply

Typhoon Bang-lang was spinning over the Western North Pacific Ocean north of Wake Island on Saturday morning.  At 5:00 a.m. EDT on Saturday the center of Typhoon Bang-lang was located at latitude 24.8°N and longitude 168.4°E which put the center about 335 miles (535 km) north-northeast of Wake Island.  Bang-lang was moving toward the north-northeast at 18 m.p.h. (30 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 971 mb.

Typhoon Bang-lang intensified during Friday night.  Thunderstorms were occurring in bands in the eastern and northern parts of Bang-lang’s circulation.  Bands in the southwestern part of Typhoon Bang-lang consisted primarily of showers and lower clouds.  Storms near the center of Bang-land generated upper level divergence that pumped mass away to the northeast of the typhoon.  The removal of mass caused the surface pressure to decrease.

The strongest winds were occurring in the eastern part of Typhoon Bang-lang.  Winds to typhoon force extended out 20 miles (30 km) in the eastern half of Bang-lang’s circulation.  Winds to tropical storm force extended out 80 miles (130 km) from the center of Typhoon Bang-lang.

Typhoon Bang-lang will move through an environment that will become unfavorable for intensification during the next 24 hours.  Bang-lang will move over water where the Sea Surface Temperatures are near 27°C.  It will move under the eastern side of an upper level trough that is east of Japan.  The upper level trough will produce southerly winds that will blow toward the top of Bang-lang’s circulation.  Those winds will cause the vertical wind shear to increase.  Typhoon Bang-lang will start to weaken when the vertical wind shear increases.  Bang-lang will move over colder water on Sunday.  It will start to weaken more quickly when it moves over the colder water.  Typhoon Bang-lang will also start to make a transition to an extratropical cyclone during the weekend because of the effects of the vertical wind shear and the colder water.

The upper level trough east of Japan will steer Typhoon Bang-lang toward the north during the next 24 hours.  On its anticipated track, Typhoon Bang-lang will move farther away from Wake Island.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Etau was north of Typhoon Bang-lang.  At 5:00 a.m. EDT on Saturday the center of Ttopical Storm Etau was located at latitude 28.7°N and longitude 165.6°E which put the center about 615 miles (995 km) north of Wake Island.  Etau was moving toward the north at 21 m.p.h. (33 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 991 mb.

Tropical Storm Saudel Brings Wind and Rain to Eastern China

Tropical Storm Saudel brought wind and rain to eastern China on Thursday night.  At 11:00 p.m. EDT on Thursday the center of Tropical Storm Saudel was located at latitude 28.0°N and longitude 120.3°E which put the center about 25 miles (40 km) west of Wenzhou, China.  Saudel was moving toward the west at 16 m.p.h. (26 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 982 mb.

The center of Typhoon Saudel made landfall on the east coast of China east of Wenzhou on Thursday evening.  Saudel weakened to a tropical storm after it made landfall on the coast.

The circulation around Tropical Storm Saudel was still well organized.  Bands of showers and thunderstorms were revolving around the center of Saudel’s circulation.

Winds to tropical storm force extended out 155 miles (250 km) from the center of Tropical Storm Saudel.

Tropical Storm Saudel will move around the southern side of a high pressure system that is over the Western North Pacific Ocean and eastern China.  The high pressure system will steer Saudel toward the west during the next 24 hours.  On its anticipated track, Tropical Storm Saudel will move inland over Zhejiang.

Tropical Storm Saudel will bring strong winds and heavy rain to Zhejang while it moves farther inland.  Heavy rain is likely to cause floods in some locations.

Tropical Storm Saudel will also bring gusty winds locally heavy rain to southern parts of Anhui and northern sections of Jiangxi.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Etau formed north of Wake Island.

At 11:00 p.m. EDT on Thursday the center of Tropical Storm Etau was located at latitude 24.5°N and longitude 167.3°E which put the center about 335 miles (540 km) north of Wake Island.   Etau was moving toward the north-northwest at 13 m.p.h. (21 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 Chan-hom Brings Wind and Rain to Honshu

Tropical Storm Chan-hom brought wind and rain to central Honshu on Tuesday morning.  At 11:00 a.m. EDT on Tuesday the center of Tropical Storm Chan-hom was located at latitude 36.0°N and longitude 139.0°E which put the center about 25 miles (40 km) north of Tokyo, Japan.  Chan-hom was moving toward the west-southwest 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 994 mb.

The center of Tropical Storm Chan-hom crossed the coast of Honshu northeast of Tokyo on Tuesday morning.

The strongest winds were occurring in the northern side of Tropical Storm Chan-hom.  Winds to tropical storm force extended out 45 miles in the northern half of Chan-hom’s circulation.  The winds in the southern half of Tropical Storm Chan-hom were blowing at less than tropical storm force.

An upper level low south of Japan will steer Tropical Storm Chan-hom toward the west during the next 24 hours.  On its anticipated track, the center of Tropical Storm Chan-hom will move across central Honshu.

Tropical Storm Chan-hom will bring gusty winds and locally heavy rain to parts of central Honshu.  Heavy rain could cause floods in some locations.

Elsewhere over the Western North Pacific Ocean, Tropical Depression Peilou continued to weaken slowly northwest of Wake Island.  At 11:00 a.m. EDT on Tuesday the center of Tropical Depression Peilou was located at latitude 26.7°N and longitude 160.1°E which put the center about 645 miles (1035 km) northwest of Wake Island.  Peilou was moving toward the east-northeast at 17 m.p.h. (28 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 999 mb.

Typhoon Dolphin Moves West of Wake Island

Typhoon Dolphin moved west of Wake Island on Thursday.  At 11:00 p.m. EDT on Thursday the center of Typhoon Dolphin was located at latitude 18.6°N and longitude 161.5°E which put the center about 315 miles (510 km) west-southwest of Wake Island.  Dolphin was moving toward the west-northwest at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 155 m.p.h. (250 km/h) and there were wind gusts to 190 m.p.h. (305 km/h).  The minimum surface pressure was 924 mb.

Typhoon Dolphin appeared to go through another eyewall replacement cycle.  A circular eye with a diameter of 30 miles (50 km) was present at the center of Dolphin’s circulation on Thursday evening.  The eye was surrounded by a ring of thunderstorms.  The strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms revolved around the core of Typhoon Dolphin.  Storms near the core of Dolphin generated strong upper level divergence that pumped large amounts of mass from the typhoon.  The removal of large amounts of mass in the upper levels was nearly equal to the convergence of mass in the lower levels of the atmosphere.  So, the surface pressure  did not change much on Thursday.

The completion of another eyewall replacement cycle increased the size of the circulation around Typhoon Dolphin.  Winds to typhoon force extended out 60 miles (95 km) from the center of Dolphin’s circulation.  Winds to tropical storm force extended out 175 miles (280 km) from the center of Typhoon Dolphin.

The Hurricane Intensity Index (HII) for Typhoon Dolphin is 33.3.  The Hurricane Size Index (HSI) is 21.0 and the Hurricane Wind Intensity Size Index (HWISI) is 54.3.  Typhoon Dolphin is similar in intensity to Hurricane Ian when Ian hit Southwest Florida in 2022.  Typhoon Dolphin is larger than Ian was.

Typhoon Dolphin will move through an environment favorable for a powerful typhoon during the next 24 hours.  Dolphin will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the middle of an upper level ridge that is over the Western North Pacific Ocean.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Typhoon Dolphin is likely to maintain its intensity on Friday.  Eyewall replacement cycles are likely to cause fluctuation in the intensity of Typhoon Dolphin during the next few days.

Typhoon Dolphin will move around the southern side of a high pressure system that is over the Western North Pacific Ocean.  The high pressure system will steer Dolphin toward the west-northwest during the next 24 hours.  On its anticipated track, the center of Typhoon Dolphin will move toward Iwo To.

Typhoon Dolphin Strengthens to Equivalent of Cat. 5 Hurricane

Typhoon Dolphin strengthened to the equivalent of a Category 5 hurricane on the Saffir-Simpson Scale as it moved over the Western North Pacific Ocean south of Wake Island on Wednesday.  At 5:00 p.m. EDT on Wednesday the center of Typhoon Dolphin was located at latitude 16.0°N and longitude 166.3°E which put the center about 240 miles (390 km) south of Wake Island.  Dolphin was moving toward the northwest at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 165 m.p.h. (265 km/h) and there were wind gusts to 200 m.p.h. (320 km/h).  The minimum surface pressure was 915 mb.

Typhoon Dolphin strengthened to the equivalent of a Category 5 hurricane on Wednesday.  A  circular eye with a diameter of 20 miles (32 km) was present at the center of Dolphin’s circulation.  The eye was surrounded by a ring of thunderstorms. The strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms revolved around the core of Typhoon Dolphin.  Storms near the core of Dolphin generated strong upper level divergence that pumped large amounts of mass from the typhoon. The removal of large amounts of mass caused the surface pressure to decrease.

The distribution of wind speeds in Typhoon Dolphin was symmetrical.  Winds to typhoon force extended out 40 miles (65 km) from the center of Dolphin’s circulation.  Winds to tropical storm force extended out 125 miles (200 km) from the center of Typhoon Dolphin.

The Hurricane Intensity Index (HII) for Typhoon Dolphin is 36.7.  The Hurricane Size Index (HSI) is 15.5 and the Hurricane Wind Intensity Size Index (HWISI) is 52.2.  Typhoon Dolphin is similar in intensity to Hurricane Otis when Otis hit Mexico in 2023.  Typhoon Dolphin is larger than Otis was.

Typhoon Dolphin will move through an environment favorable for a powerful typhoon during the next 24 hours.  Dolphin will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the middle of an upper level ridge that is over the Western North Pacific Ocean.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Typhoon Dolphin could continue to intensify during the next few hours.  Eyewall replacement cycles are likely to cause fluctuation in the intensity of Typhoon Dolphin during the next few days.

Typhoon Dolphin will move around the southern side of a high pressure system that is over the Western North Pacific Ocean.  The high pressure system will steer Dolphin toward the northwest during the next 24 hours.  On its anticipated track, the center of Typhoon Dolphin will be east of Iwo To by the end of the weekend.

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.
