Typhoon Bavi Intensifies to Equivalent of a Major Hurricane

Typhoon Bavi intensified to the equivalent of a major hurricane on Thursday night.  The threat posed by Bavi prompted the issuance of Typhoon Watches and Tropical Storm Watches for the Marianas.  At 5:00 a.m. EDT on Friday the center of Typhoon Bavi was located at latitude 12.9°N and longitude 153.8°E which put the center about 625 miles (1010 km) east of Guam.  Bavi was moving toward the west at 13 m.p.h. (21 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 955 mb.

Typhoon Watches are in effect for Guam, Rota, Tinian, and Saipan.

Tropical Storm Watches are in effect for Alamagan, Pagan, and Agrihan.

A circular eye with a diameter of 21 miles (33 km) was at the center of Typhoon Bavi.  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 core of Bavi’s circulation.  Storms near the core of Bavi generated strong upper level divergence that pumped large quantities of mass away from typhoon.  The removal of large quantities of mass caused the surface pressure to decrease rapidly.

The circulation around Typhoon Bavi was fairly symmetrical.  Winds to typhoon force extended out 50 miles (80 km) from the center of Bavi’s circulation.  Winds to tropical storm force extended out 150 miles (240 km) from the center of Typhoon Bavi.

The Hurricane Intensity Index (HII) for Typhoon Bavi is 22.1.  The Hurricane Size Index (HSI) is 18.6 and the Hurricane Wind Intensity Size Index (HWISI) is 40.7.  Typhoon Bavi is similar in intensity to Hurricane Jeanne when Jeanne hit South Florida in 2004.  Bavi is not quite as large as Jeanne was.

Typhoon Bavi will more through an environment that will be very favorable for intensification during the next 24 hours.  Bavi 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.  Typhoon Bavi will intensify during the next 24 hours.  Bavi could intensify rapidly at times.  Typhoon Bavi could strengthen to the equivalent of a Category 5 hurricane on the Saffir-Simpson Scale during the next 24 hours.

Typhoon Bavi 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 Bavi toward the west during the next 24 hours.  On its anticipated track, Typhoon Bavi could reach the Marianas in less than 60 hours.

Typhoon Bavi will bring strong winds and heavy rain to the Marianas.  Bavi could be capable of causing catastrophic damage.  Heavy rain will cause flash floods in some locations.

Flood Watches are in effect for Guam, Rota, Tinian, and Saipan.

Typhoon Bavi could cause a storm surge of up to 16 feet (5 meters) along the coast of the Marianas.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Maysak was bringing gusty winds and locally heavy rain to Hainan.  At 5:00 a.m. EDT on Friday the center of Tropical Storm Maysak was located at latitude 17.9°N and longitude 109.4°E which put the center about 25 miles (40 km) south of Sanya, China.  Maysak was moving toward the northwest at 6 m.p.h. (10 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.

Bavi Strengthens to a Typhoon

Former Tropical Storm Bavi strengthened to a typhoon over the Western North Pacific Ocean east of the Marianas on Thursday.  At 5:00 p.m. EDT on Thursday the center of Typhoon Bavi was located at latitude 12.7°N and longitude 156.1°E which put the center about 790 miles (1275 km) east of Guam.  Bavi was moving toward the west-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 982 mb.

Former Tropical Storm Bavi strengthened to a typhoon on Thursday.  The inner end of a rainband wrapped around the center of Bavi’s circulation.  A circular eye formed at the center of Typhoon Bavi.  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 Bavi’s circulation.  Storms near the center of Bavi generated upper level divergence that pumped mass away from the typhoon.  The removal of mass caused the surface pressure to decrease.

The size of the circulation around Typhoon Bavi increased on Thursday as Bavi intensified.  Winds to typhoon force extended out 50 miles (80 km) from the center of Bavi’s circulation.  Winds to tropical storm force extended out 160 miles (260 km) from the center of Typhoon Bavi.

Typhoon Bavi will more through an environment that will be very favorable for intensification during the next 24 hours.  Bavi 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.  Typhoon Bavi will intensify during the next 24 hours.  Bavi could intensify rapidly at times. Typhoon Bavi could strengthen to the equivalent of a major hurricane during the next 24 hours.

Typhoon Bavi 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 Bavi toward the west-northwest during the next 24 hours.  On its anticipated track, Typhoon Bavi could reach the Marianas in less than 72 hours.

Typhoon Bavi will bring strong winds and heavy rain to the Marianas.  Bavi could be capable of causing catastrophic damage.  Heavy rain will cause flash floods in some locations.

Elsewhere over the Western North Pacific Ocean, former Tropical Depression 10W strengthened to Tropical Storm Maysak southeast of Hainan.  At 5:00 p.m. EDT on Thursday the center of Tropical Storm Maysak was located at latitude 17.6°N and longitude 110.2°E which put the center about 50 miles (80 km) southeast of Sanya, China.  Maysak was moving toward the west 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 1002 mb.

Tropical Storm Bavi Intensifies

Tropical Storm Bavi was intensifying over the Western North Pacific Ocean east of the Marianas on Wednesday night.  At 11:00 p.m. EDT on Wednesday the center of Tropical Storm Bavi was located at latitude 11.2°N and longitude 159.7°E which put the center about 1050 miles (1690 km) east of Guam.  Bavi was moving toward the west-northwest 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 996 mb.

Former Tropical Depression 09W intensified on Wednesday and the Japan Meteorological Agency designated the system as Tropical Storm Bavi.

The circulation around Tropical Storm Bavi exhibited much more organization on Wednesday evening.  The inner end of a rainband wrapped around the western side of the center of Bavi’s circulation.  Other bands of showers and thunderstorms were revolving around the center of Tropical Storm Bavi.  Storms near the center of Bavi generated more upper level divergence that pumped mass away from the tropical storm.  The removal of more mass caused the surface pressure to decrease.

The distribution of wind speeds in Tropical Storm Bavi became more symmetrical on Wednesday.  Winds to tropical storm force extended out 80 miles (130 km) from the center of Bavi’s circulation.

Tropical Storm Bavi will more through an environment that will be very favorable for intensification during the next 24 hours.  Bavi 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.  Tropical Storm Bavi is likely to intensify to a typhoon during the next 24 hours.  Bavi could intensify rapidly at times.  Tropical Storm Bavi is likely to strengthen to the equivalent of a major hurricane by the weekend.

Tropical Storm Bavi 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 Bavi toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Bavi could reach the Marianas in less than four days.

Tropical Storm Bavi is likely to intensify to the equivalent of a major hurricane before it reaches the Marianas.

Elsewhere over the Western North Pacific Ocean, Tropical Depression 10W formed over the South China Sea.  At 11:00 p.m. EDT on Wednesday the center of Tropical Depression 10W was located at latitude 17.7°N and longitude 112.6°E which put the center about 250 miles (400 km) east-southeast of Sanya, China.  The tropical depression was moving toward the west at 21 m.p.h. (33 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 1003 mb.

Tropical Depression 10W is forecast to strengthen to a tropical storm before it reaches Hainan.  It will bring strong winds and locally heavy rain to Hainan.  Heavy rain could cause flash floods in some locations.

Tropical Depression Forms East-southeast of Marianas

Tropical Depression 09W formed over the Western North Pacific Ocean east-southeast of the Marianas on Tuesday evening.  At 11:00 p.m. EDT on Tuesday the center of Tropical Depression 09W was located at latitude 8.9°N and longitude 162.9°E which put the center about 175 miles (280 km) east-southeast of Ujelang.  The tropical depression was moving toward the west at 12 m.p.h. (19 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 1003 mb.

A low pressure system over the Western North Pacific Ocean east-southeast of the Marianas strengthened on Tuesday evening.  Both the Japan Meteorological Agency and the U.S. Joint Typhoon Warning Center classified the system as a tropical depression.

More thunderstorms formed near the center of Tropical Depression 09W on Tuesday evening.  Thunderstorms were also developing in bands in the northern and western parts of the tropical depression.  Bands in the southern and eastern parts of Tropical Depression consisted primarily of showers and lower clouds.  Storms near the center of circulation began to generate upper level divergence that pumped mass away to the west of the tropical depression.  The removal of mass caused the surface pressure to start to decrease.

Tropical Depression 09W will move through an environment favorable for intensification during the next 24 hours.  The tropical depression will move over water where the Sea Surface Temperatures are near 30°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Tropical Depression 09W will intensify to a tropical storm during the next 24 hours.  It is likely to strengthen to a typhoon by the end of the week.

Tropical Depression 09W will move around the southern part of a high pressure system that is over the Western North Pacific Ocean.  The high pressure system will steer the tropical depression toward the west-northwest during the next 24 hours.  On its anticipated track, the center of Tropical Depression 09W will pass near Ujelang in 12 hours.  Tropical Depression 09W could approach the Marianas in four days.  It is likely to be a typhoon when it approaches the Marianas.

Tropical Depression 09W will bring gusty winds and heavy rain to Ujelang.  Heavy rain could cause flash floods.

Tropical Storm Wipha brought wind and rain to northern Vietnam on Monday.  At 5:00 p.m. EDT on Monday the center of Tropical Storm Wipha was located at latitude 20.8°N and longitude 107.2°E which put the center about 30 miles (50 km) east of Haiphong, Vietnam.  Wipha was moving toward the west-southwest at 8 m.p.h. (13 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 984 mb.

Tropical Storm Wipha brought wind and rain to parts of northern Vietnam on Monday.  The strongest winds were occurring in the part of Wipha’s circulation that was over the Gulf of Tonkin.

Winds to tropical storm force extended out 150 miles (240 km) in the southern side of Tropical Storm Wipha.  Winds to tropical storm force extended out 85 miles (135 km) in the northern side of Wipha’s circulation.

Tropical Storm Wipha will move around the southern part of a high pressure system over China.  The high pressure system will steer Wipha toward the west-southwest during the next 24 hours.  On its anticipated track, Tropical Storm Wipha will move across northern Vietnam.  The center of Wipha’s circulation will pass south of Hanoi in about 12 hours.  Wipha will move over northern Laos on Tuesday night.

Tropical Storm Wipha will weaken gradually as it moves across northern Vietnam.  Wipha will weaken to a tropical depression on Tuesday.

Tropical Storm Wipha will continue to produce strong winds and to drop heavy rain as it moves across northern Vietnam.  Heavy rain is likely to cause floods in some locations.  Wipha will also drop heavy rain over parts of northern Laos.  Additional floods could occur in that region.

Tropical Storm Wipha Brings Wind and Rain to Southern China

Tropical Storm Wipha brought wind and rain to southern China on Sunday.  At 11:00 a.m. EDT on Sunday the center of Tropical Storm Wipha was located at latitude 21.6°N and longitude 111.2°E which put the center about 70 miles (110 km) east-northeast of Zhanjiang, China.  Wipha was moving toward the west 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.

Former Typhoon Wipha weakened to a tropical storm after it made landfall on the coast of southern China west of Hong Kong.  Tropical Storm Wipha was bringing strong winds and heavy rain to parts of southern China on Sunday.

A weather station at Hong Kong airport (VHHH) reported a sustained wind speed of 46 knots (53 m.p.h. or 85 km/h) as the center of then Typhoon Wipha passed south of the station.  The same weather station also reported a wind gust of 65 knots (75 m.p.h. or 120 km/h).

The circulation around Tropical Storm Wipha remains well organized even though the center of Wipha’s circulation has been overland for a few hours.  A broken ring of thunderstorms surrounds the center of Tropical Storm Wipha.  The strongest winds are occurring in that ring of storms.  Thunderstorms are occurring in bands in the western side of Wipha’s circulation.  Bands in the northern and eastern parts of Tropical Storm Wipha consist primarily of showers and lower clouds.

The strongest winds in Tropical Storm Wipha are occurring in the part of Wipha’s circulation that is over the northern South China Sea.  Winds to tropical storm force extended out 155 miles (250 km) from the center of Tropical Storm Wipha.

Tropical Storm Wipha will move around the southern part of a high pressure system over eastern China.  The high pressure system will steer Wipha toward the west-southwest during the next 24 hours.  On its anticipated track, the center of Tropical Storm Wipha will move along the coast of southern China during the next 12 hours.  The center of Wipha’s circulation could move over the northern Gulf of Tonkin on Monday.

Tropical Storm Wipha will bring strong winds and locally heavy rain to southwestern Guangdong.  Heavy rain could cause flash floods in some location.  Tropical Storm Wipha will also produce strong winds and heavy rain in southern Guangxi and in Hainan.  Tropical Storm Wipha could bring strong winds and locally heavy rain to northern Vietnam early next week.

Tropical Storm Wipha will weaken slowly as long as the center of circulation remains over land.  If the center of Wipha’s circulation  moves over the Gulf of Tonkin on Monday, then Wipha would move through an environment somewhat favorable for intensification.  Tropical Storm Wipha would move over water where the Sea Surface Temperatures are near 29°C.  It would move under the southern side of an upper level ridge that is over China.  The upper level ridge will produce northeasterly winds that will blow toward the top of Wipha’s circulation. Those winds will cause some vertical wind shear.  The vertical wind shear will inhibit intensification but the wind shear may not be enough to prevent intensification. Tropical Storm Wipha could intensify a little  on Monday if the center of Wipha’s circulation moves over the Gulf of Tonkin.

Wipha Intensifies to a Typhoon Near Hong Kong

Former Tropical Storm Wipha intensified to a typhoon near Hong Kong on Saturday night.  At 11:00 p.m. EDT on Saturday the center of Typhoon Wipha was located at latitude 21.6°N and longitude 113.9°E which put the center about 55 miles (95 km) south-southeast of Hong Kong.  Wipha was moving toward the west at 15 m.p.h. (24 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 970 mb.

Former Tropical Storm Wipha intensified to a typhoon on Saturday night near Hong Kong.  The center of Typhoon Wipha was still over water just to the south-southeast of Hong Kong.  The inner end of a rainband wrapped most of the way around the center of Wipha’s circulation. Thunderstorms were occurring in bands in the southern and eastern parts of Typhoon Wipha. Bands in the northern part of Wipha’s circulation  consisted primarily of showers and lower clouds.  Storms near the center of Wipha generated upper level divergence that pumped mass away to the southwest of the tropical storm.  The removal of mass caused the surface pressure to decrease.

The strongest winds were occurring in the southern side of Typhoon Wipha.  Winds to typhoon force extended out 30 miles (50 km) in the southern half of Wipha’s circulation.  Winds to tropical storm force extended out 155 miles (250 km from the center of Typhoon Wipha.

Typhoon Wipha will move through an environment favorable for intensification during the next 12 hours . Wipha will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the southeastern side of an upper level ridge that is over China.  The upper level ridge will produce northeasterly winds that will blow toward the top of Wipha’s circulation.  Those winds will cause some vertical wind shear.  The vertical wind shear will inhibit intensification but the wind shear may be enough to prevent intensification. Typhoon Wipha could intensify a little more during the next 12 hours.

Typhoon Wipha will move around the southern part of a high pressure system over eastern China.  The high pressure system will steer Wipha toward the west during the next 24 hours.  On its anticipated track, the center of Typhoon Wipha will pass just south of Hong Kong during the next few hours.  The center of Wipha’s circulation will also pass just south of Macau.  The center of Typhoon Wipha could be near Yangjiang in 18 hours.

Tropical Storm Wipha Passes Near Northern Luzon

The center of Tropical Storm Wipha passed just to the north of northern Luzon on Friday.  At 11:00 a.m. EDT on Friday the center of Tropical Storm Wipha was located at latitude 19.6°N and longitude 122.0°E which put the center about 80 miles (130 km) north-northeast of Aparri, Philippines.  Wipha was moving toward the northwest at 13 m.p.h. (21 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 991 mb.

The center of Tropical Storm Wipha was passing between northern Luzon and Taiwan on Friday.  More thunderstorms formed near the center of Wipha’s circulation on Friday.  Numerous bands of showers and thunderstorms were revolving around the center of Tropical Storm Wipha.  Storms near the center of Wipha generated upper level divergence that pumped mass away to the south and west of the tropical storm.  The removal of mass caused the surface pressure to decrease.

The circulation around Tropical Storm Wipha was very large.  Winds to tropical storm force extended out 205 miles (330 km) from the center of Wipha’s circulation.

Tropical Storm Wipha will move through an environment favorable for intensification during the next 24 hours.  Wipha will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the southern side of an upper level ridge that is north of the Philippines.  The upper level ridge will produce easterly winds that will blow toward the top of Wipha’s circulation.  Those winds will cause some vertical wind shear, but the wind shear will not be enough to prevent intensification.  Tropical Storm Wipha will intensify during the next 24 hours.  Wipha could strengthen to a typhoon during the weekend.

Tropical Storm Wipha will move around the southwestern part of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Wipha toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Wipha could approach Hong Kong in 36 hours.

Tropical Storm Wipha will produce gusty winds and locally heavy rain in northern Luzon and southern Taiwan during the rest of today.  Heavy rain could produce flash floods in some locations.

Typhoon Haikui Nears Taiwan

Typhoon Haikui neared Taiwan on Saturday. At 5:00 p.m. EDT on Saturday the center of Typhoon Haikui was located at latitude 22.6°N and longitude 122.7°E which put it about 100 miles (160 km) east-southeast of Taitung, Taiwan. Haikui 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 958 mb.

Typhoon Haikui intensified as it neared Taiwan on Saturday. A small circular eye was at the center of Haikui’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 were revolving around the core of Typhoon Haikui. Storms near the core generated upper level divergence that pumped mass away from the typhoon.

The Taiwan Central Weather Bureau’s radar images indicated that Typhoon Haikui was very symmetrical. Winds to typhoon force extended out 35 miles (55 km) from the center of Haikui’s circulation. Winds to tropical storm force extended out 115 miles (185 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Haikui was 17.8. The Hurricane Size Index (HSI) was 9.7 and the Hurricane Wind Intensity Size Index (HWISI) was 27.5. Typhoon Haikui was similar in size and intensity to Hurricane Zeta when Zeta hit Louisiana in 2020.

Typhoon Haikui will move through an environment favorable for intensification during the next few hours. Haikui will move over water where the Sea Surface Temperatures are near 30°C. It will move under the southern part of an upper level ridge centered north of Taiwan. The ridge will produce easterly winds that will blow toward the top of Haikui’s circulation. The winds in the lower levels of the atmosphere will also blow from the east. So, there will be little vertical wind shear. Typhoon Haikui is likely to continue to intensify during the next few hours until it makes landfall on Taiwan.

Typhoon Haikui will move around the southern part of a high pressure system over the Western North Pacific Ocean. The high pressure system will steer Haikui toward the west- northwest during the next 24 hours. On its anticipated track, the center of Typhoon Haikui will move landfall on the coast of southeast Taiwan near Taitung in nine hours.

Typhoon Haikui will bring strong winds and heavy rain to Taiwan. Haikui will be capable of causing regional serious damage. The heaviest rain will fall on the eastern sides of mountains where the wind will push air up the slopes. Heavy rain is likely to cause flash floods.

Elsewhere over the Western North Pacific Ocean, former Typhoon Saola weakened to a tropical storm along the coast of southern China and former Tropical Storm Kirogi weakened to a tropical depression south of Japan.
