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.

Typhoon Kajiki Brings Wind and Rain to Hainan

Typhoon Kajiki brought wind and rain to Hainan on Sunday.  At 5:00 a.m. EDT on Sunday the center of Typhoon Kajiki was located at latitude 17.5°N and longitude 109.8°E which put the center about 50 miles (80 km) south-southeast of Sanya, China.  Kajiki was moving toward the west at 11 m.p.h. (17 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.

Typhoon Kajiki rapidly intensified to the equivalent of a Category 2 hurricane on the Saffir-Simpson Scale during Saturday night.  A circular eye with a diameter of 25 miles (40 km) formed at the center of Kajiki’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 center of Typhoon Kajiki.  Storms near the center of Kajiki generated strong upper level divergence that pumped large quantities of mass away from the typhoon.  The removal of large amounts of mass caused the surface pressure to decrease rapidly.

The circulation around Typhoon Kajiki became more symmetrical when it rapidly intensified.  Winds to typhoon force extended out 30 miles (50 km) from the center of Kajiki’s circulation.  Winds to tropical storm force extended out 115 miles (185 km) from the center of Typhoon Kajiki.

The Hurricane Intensity Index (HII) for Typhoon Kajiki is 17.8.  The Hurricane Size Index (HSI) is 11.3 and the Hurricane Wind Intensity Size Index (HWISI) is 29.1.  Typhoon Kajiki is similar in size and intensity to Hurricane Sally when Sally hit South Alabama in 2020.

Typhoon Kajiki will move through an environment that is favorable for intensification during the next 24 hours.  Kajiki 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 northeasterly winds that will blow toward the top of Kajiki’s circulation.  The winds in the lower levels of the atmosphere will also blow from the northeast.  So, there will be little vertical wind shear.  Typhoon Kajiki will intensify during the next 24 hours as long as the center remains south of Hainan.  Kajiki could strengthen to the equivalent of a major hurricane.

Typhoom Kajiki will move around the southern side of a high pressure system over China.  The high pressure system will steer Kajiki toward the west during the next 24 hours.  On its anticipated track, the center of Typhoon Kajiki will continue to pass south of Hainan during the next 12 hours.  Kajiki will hit the coast of  northern Vietnam in 24 hours.

Typhoon Kajiki will continue bring strong winds and heavy rain to Hainan during the next 12 hours.  Heavy rain is likely to cause flash floods in some locations.

Typhoon Kajiki will also bring strong winds and heavy rain to northern Vietnam.  Heavy rain is likely to cause flash floods there as well.  Typhoon Kajiki could cause a storm surge of up to 10 feet (3 meters) along the coast of northern Vietnam.

Kajiki Strengthens to a Typhoon

Former Tropical Storm Kajiki strengthened to a typhoon over the South China Sea southeast of Hainan on Saturday night.  At 11:00 p.m. EDT on Saturday the center of Typhoon Kajiki was located at latitude 17.3°N and longitude 110.6°E which put the center about 85 miles (135 km) south-southeast of Lingshui, China.  Kajiki was moving toward the west at 13 m.p.h. (21 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 985 mb.

Former Tropical Storm Kajiki strengthened to a typhoon on Saturday night. The inner end of a rainband wrapped around the center of Typhoon Kajiki.  A small circular eye was visible at the center of Kajiki’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 center of Typhoon Kajiki.  Storms near the center of Kajiki 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 Kajiki increased as Kajiki strengthened on Saturday.  Winds to typhoon force extended out 40 miles (65 km) from the center of Kajiki’s circulation.  Winds to tropical storm force extended out 145 miles (235 km) from the center of Typhoon Kajiki.

Typhoon Kajiki will move through an environment that is favorable for intensification during the next 24 hours.  Kajiki 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 northeasterly winds that will blow toward the top of Kajiki’s circulation.  The winds in the lower levels of the atmosphere will also blow from the northeast.  So, there will be little vertical wind shear.  Typhoon Kajiki will intensify during the next 24 hours as long as the center passes south of Hainan.

Typhoom Kajiki will move around the southern side of a high pressure system over China.  The high pressure system will steer Kajiki toward the west during the next 24 hours.  On its anticipated track, the center of Typhoon Kajiki will pass south of Hainan during the next 12 hours.  Kajiki will approach northern Vietnam in 24 hours.

Typhoon Kajiki will bring strong winds and heavy rain to Hainan.  Heavy rain is likely to cause flash floods in some locations.

Typhoon Kajiki will also bring strong winds and heavy rain to northern Vietnam.  Heavy rain is likely to cause flash floods there as well.  Typhoon Kajiki could cause a storm surge of up to 8 feet (2.4 meters) along the coast of northern Vietnam.

Tropical Storm Kajiki Forms Over South China Sea

Tropical Storm Kajiki formed over the South China Sea on Friday night.  At 11:00 p.m. EDT on Friday the center of Tropical Storm Kajiki was located at latitude 17.6°N and longitude 115.9°E which put the center about 365 miles (590 km) south-southeast of Hong Kong.  Kajiki was moving toward the west-northwest at 12 m.p.h. (19 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 1000 mb.

A low pressure system over the South China Sea strengthened on Friday evening and the Japan Meteorological Agency designated the system as Tropical Storm Kajiki.

The circulation around Tropical Storm Kajiki exhibited much more organization on Friday night.  Numerous thunderstorms were forming around the center of Kajiki’s circulation.  Thunderstorms also developed in bands revolving around the center of Tropical Storm Kajiki.  Storms near the center of Kajiki 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 around Tropical Storm Kajiki was asymmetrical.  Winds to tropical storm force extended out 130 miles (210 km) in the northwestern quadrant of Kajiki’s circulation.  Winds to tropical storm force extended out 80 miles (130 km) in the other parts of Tropical Storm Kajiki.

Tropical Storm Kajiki will move through an environment that is favorable for intensification during the next 24 hours.  Kajiki 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 Kajiki’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.  Tropical Storm Kajiki will intensify during the next 24 hours.  Kajiki could strengthen to a typhoon during the weekend.

Tropical Storm 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, Tropical Storm Kajiki will approach southern Hainan in 24 hours.

Tropical Storm Kajiki could be a typhoon when it approaches southern Hainan.  Kajiki will bring strong winds and heavy rain to Hainan.  Heavy rain is likely to cause flash floods in some locations.

Lingling Strengthens to Typhoon South of Ryukyu Islands

Former Tropical Storm Lingling strengthened to a typhoon south of the Ryukyu Islands on Tuesday.  At 11:00 a.m. EDT on Tuesday the center of Typhoon Lingling was located at latitude 21.7°N and longitude 124.3°E which put it about 180 miles (295 km) south of Ishigaki, Japan.  Lingling was moving toward the north at 8 m.p.h. (13 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 979 mb.

Typhoon Lingling exhibited much greater organization on Tuesday.  A circular eye with a diameter of 30 miles (50 km) developed at the center of circulation.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Typhoon Lingling.  The strongest rainbands were occurring in the southeastern half of the circulation.  Storms near the core of Lingling were generating upper level divergence which was pumping mass away from the typhoon.  Winds to typhoon force extended out about 30 miles from the center of circulation.  Winds to tropical storm force extended out about 140 miles (220 km) from the center.

Typhoon Lingling will move through an environment favorable for intensification during the next 24 to 48 hours.  Lingling will move over water where the Sea Surface Temperature is near 28°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Typhoon Lingling is likely to continue to intensify and it could strengthen into the equivalent of a major hurricane in a couple of days.

Typhoon Lingling is moving around the western end of a large subtropical ridge over the Western North Pacific Ocean.  The ridge will steer Lingling toward the north during the next several days.  On its anticipated track Typhoon Lingling could reach the southern Ryukyu Islands within 24 hours.  Lingling will bring strong, gusty winds and heavy rain to those islands.  Typhoon Lingling could approach Kyushu and South Korea in about three days.

Elsewhere over the Western North Pacific Ocean, Tropical Depression Kajiki was dropping heavy rain over parts of Vietnam and Laos.  At 11:00 a.m. EDT on Tuesday the center of Tropical Depression Kajiki was located at latitude 16.4°N and longitude 107.3°E which put it about 65 miles (105 km) west-northwest of Da Nang, Vietnam.  Kajiki was moving toward the west at 8 m.p.h. (13 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 998 mb.

Tropical Storm Kajiki Forms Near Vietnam

Tropical Storm Kajiki formed near the coast of Vietnam on Monday.  At 5:00 p.m. EDT on Sunday the center of Tropical Storm Kajiki was located at latitude 16.6°N and longitude 107.6°E which put it about 50 miles (80 km) northeast of Vinh Linh, Vietnam.  Kajiki was moving toward the 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 996 mb.

The wind speed around a low pressure system just east of the coast of Vietnam increased to 40 m.p.h. (65 km/h) on Monday and the Japan Meteorological Agency designated the system as Tropical Storm Kajiki.  The distribution of thunderstorms around Kajiki was asymmetrical.  Many of the stronger thunderstorms were occurring in bands in the western half of the circulation.  Bands in the eastern half of Tropical Storm Kajiki contained fewer thunderstorms.  Kajiki was moving south of an upper level ridge over eastern Asia.  The ridge was producing northeasterly winds which were blowing toward the top of the tropical storm.  Those winds were causing moderate vertical wind shear and they were the reason for the asymmetrical distribution of thunderstorms.

The upper level ridge will steer Tropical Storm Kajiki toward the southwest during the next 12 to 24 hours.  On it anticipated track Kajiki will reach the coast of Vietnam within 12 hours.  Even though Tropical Storm Kajiki will move over water where the Sea Surface Temperature is near 30°C, it will have only a few hours to strengthen before the center reaches the coast.  Kajiki will bring some gusty winds to the coast, but the greater risk is for heavy rain.  Tropical Storm Kajiki will drop locally heavy rain over parts of central Vietnam and northern Laos.  Heavy rain could cause flash floods in some locations.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Lingling was strengthening as it north toward the southern Ryukyu Islands.  At 5:00 p.m. EDT on Sunday the center of Tropical Storm Lingling was located at latitude 19.5°N and longitude 124.1°E which put it about 565 miles (915 km) south-southwest of Okinawa.  Lingling was moving toward the north-northwest at 13 m.p.h. (20 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 Lingling is forecast to strengthen into a typhoon before it reaches the southern Ryukyu Islands.
