Typhoon Danas Brings Wind and Rain to Taiwan

Typhoon Danas brought strong winds and heavy rain to Taiwan on Sunday.  Danas weakened to a tropical storm after it moved across Taiwan.  At 11:00 p.m. EDT on Sunday the center of Tropical Storm Danas was located at latitude 25.9°N and longitude 121.6°E which put the center about 30 miles (50 km) north-northwest of Taipei, Taiwan.  Danas was moving toward the north-northeast at 22 m.p.h. (35 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 989 mb.

The center of former Typhoon Danas moved north-northeast across western Taiwan on Sunday.  Danas produced strong winds and heavy rains as it moved across Taiwan.  The heaviest rain fell in parts of southern Taiwan and in a few mountain areas where the winds were blowing up the slopes.  The Central Weather Administration’s radar estimated that up to a foot (300 mm) of rain fell in some locations.

Former Typhoon Danas weakened to a tropical storm as it moved across western Taiwan.  The center of Danas’ circulation moved over the East China Sea on Sunday night.  Thunderstorms were still occurring near the center of Tropical Storm Danas.  Thunderstorms were also still occurring in bands revolving around the center of Danas’ circulation.

The distribution of wind speeds in Tropical Storm Danas was asymmetrical.  Winds to tropical storm force extended out 175 miles (280 km) in the eastern side of Danas’ circulation.  Winds to tropical storm force extended out 80 miles (130 km) in the western side of Danas.

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

The upper level low over eastern China will steer Tropical Storm Danas toward the north-northeast during the next 24 hours.  On its anticipated track, Danas will move away from Taiwan.  Tropical Storm Danas could approach the east coast of China in 36 hours.

Wind speeds will decrease in Taiwan when Tropical Storm Danas moves farther away.  Heavy rain should also diminish as the circulation around Danas moves away from Taiwan.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Mun weakened east of Japan.  At 11:00 p.m. EDT on Sunday the center of Tropical Storm Mun was located at latitude 35.5°N and longitude 148.7°E which put the center about 520 miles (835 km) east of Tokyo, Japan.  Mun was moving toward the north-northwest at 12 m.p.h. (19 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 986 mb.

Danas Intensifies to a Typhoon Southwest of Taiwan

Former Tropical Storm Danas intensified to a typhoon over the South China Sea southwest of Taiwan on Saturday.  At 5:00 p.m. EDT on Saturday the center of Typhoon Danas was located at latitude 21.4°N and longitude 118.3°E which put the center about 170 miles (275 km) southwest of Kaohsiung, Taiwan.  Danas was moving toward the north-northeast at 4 m.p.h. (6 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 977 mb.

Former Tropical Storm Dana intensified to a typhoon over the South China Sea southwest of Taiwan on Saturday.  The distribution of thunderstorms in Typhoon Danas became more symmetrical as Danas intensified.  More thunderstorms developed near the center of Danas’ circulation.  More thunderstorms also formed in bands revolving around the center of Typhoon Danas.  Storms near the center of Danas 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 Danas increased as Danas intensified.  Winds to typhoon force extended out 35 miles (55 km) from the center of Danas’ circulation.  Winds to tropical storm force extended out 140 miles (220 km) from the center of Typhoon Danas.

Typhoon Danas will move through an environment mostly favorable for intensification during the next 18 hours.  Danas will move over water where where the Sea Surface Temperatures are near 29°C.  It will move under the western part of an upper level ridge over that is centered east of Taiwan.  The upper level ridge will produce southwesterly winds that will blow toward the top of Danas’ 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. Typhoon Danas will intensify during the next 18 hours.  Danas could intensify rapidly at times.

Typhoon Danas will move around the western end of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Danas toward the north-northeast during the next 24 hours.  On its anticipated track, Typhoon Danas will approach the west coast of Taiwan in 18 hours.

Typhoon Danas will bring strong winds and locally heavy rain to Taiwan. Heavy rain is likely to cause flash floods. Typhoon Danas could also cause a storm surge of up to 10 feet (3 meters) along parts of the coast of Taiwan.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Mun continued to churn east-southeast of Japan.  At 5:00 p.m. EDT on Saturday the center of Tropical Storm Mun was located at latitude 32.0°N and longitude 148.9°E which put the center about 575 miles (925 km) east-southeast of Tokyo, Japan.  Mun was moving toward the northeast 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 983 mb.

Tropical Storm Danas Forms Southwest of Taiwan

Tropical Storm Danas formed over the South China Sea southwest of Taiwan on Friday.  At 5:00 p.m. EDT on Friday the center of Tropical Storm Danas was located at latitude 20.2°N and longitude 117.3°E which put the center about 265 miles (430 km) southwest of Kaohsiung, Taiwan.  Danas was moving toward the west at 5 m.p.h. (8 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 994 mb.

A low pressure system over the South China Sea southwest of Taiwan strengthened on Friday and the Japan Meteorological Agency designated the system as Tropical Storm Danas.

The distribution of thunderstorms in Tropical Storm Danas was asymmetrical.  Thunderstorms were occurring in bands in the southern half of Danas’ circulation.  Bands in the northern half of Tropical Storm Danas consisted primarily of showers and lower clouds.  Storms near the center of Danas generated upper level divergence that pumped mass away to the south of the tropical storm.  The removal of mass caused the surface pressure to decrease.

The circulation around Tropical Storm Danas was small.  Winds to tropical storm force extended out 70 miles (110 km) from the center of Danas’ circulation.

Tropical Storm Danas will move through an environment mostly favorable for intensification during the next 24 hours.  Danas will move over water where where the Sea Surface Temperatures are near 29°C.  It will move under the southern part of an upper level ridge over eastern China.  The upper level ridge will produce northeasterly winds that will blow toward the top of Danas’ circulation.  Those winds will cause moderate vertical wind shear.  The wind shear will inhibit intensification, but the shear will not be enough to prevent intensification.  Tropical Storm Danas will intensify during the next 24 hours.  Danas could strengthen to a typhoon during the weekend,

Tropical Storm Danas will move around the western end of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Danas toward the north during the next 24 hours.  On its anticipated track,  Tropical Storm Danas will move toward the Taiwan Strait.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Mun continued to meander southeast of Japan.  At 5:00 p.m. EDT on Friday the center of Tropical Storm Mun was located at latitude 30.8°N and longitude 146.3°E which put the center about 485 miles (780 km) southeast of Tokyo, Japan.  Mun was moving toward the northeast at 9 m.p.h. (15 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.

Tropical Storm Wutip Makes Landfall in Southern China

Tropical Storm Wutip made landfall on the coast of southern China near Lianjiang on Friday night.  At 5:00 a.m. EDT on Saturday the center of Tropical Storm Wutip was located at latitude 21.7°N and longitude 110.3°E which put the center about 15 miles (25 km) southwest of Lianjiang, China.  Wutip was moving toward the northeast 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. (130 km/h).  The minimum surface pressure was 985 mb.

Tropical Storm Wutip strengthened to a typhoon just before it made landfall in southern China on Friday night.  Wutip weakened back to a tropical storm after it made landfall.  The circulation around Tropical Storm Wutip was small.  Winds to tropical storm force extended out 100 miles (160 km) from the center of Wutip’s circulation.

Tropical Storm Wutip will move around the northwestern part of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Wutip toward the northeast during the next 24 hours.  On its anticipated track, Tropical Storm Wutip will move across Guangdong.  Wutip will pass north of Hong Kong.

Tropical Storm Wutip will bring strong winds and heavy rain to southern China.  The strongest winds and heaviest rain will occur in Guangdong . Heavy rain could cause flash floods in some locations.

Tropical Storm Wutip will weaken gradually as it moves across southern China.

Wutip Strengthens to a Typhoon Near Southern China

Former Tropical Storm Wutip strengthened to a typhoon near southern China on Friday evening.  At 11:00 p.m. EDT on Friday the center of Typhoon Wutip was located at latitude 20.8°N and longitude 109.4°E which put the center about 80 miles (130 km) southwest of Lianjiang, China.  Wutip was moving toward the north-northeast at 7 m.p.h. (11 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.

Former Tropical Storm Wutip strengthened to a typhoon as it neared the coast of southern China on Friday evening.  The inner end of a rainband wrapped around the center of Wutip’s circulation.  A small circular eye with a diameter of 15 miles (24 km) formed at the center of Typhoon Wutip.  The eye was surrounded by a thin 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 Wutip’s circulation.  Storms near the center of Wutip 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 Wutip decreased a little on Friday.  Winds to typhoon force extended out 25 miles (40 km) from the center of Wutip’s circulation.  Winds to tropical storm force extended out 100 miles (160 km) from the center of Typhoon Wutip.

Typhoon Wutip will move through an environment favorable for intensification during the next few hours before it makes landfall in China.  Wutip will move over water where where the Sea Surface Temperatures are near 30°C.  It will move under the axis of an upper level ridge over eastern China.  The upper level winds are weak near the axis of the ridge and there will be little vertical wind shear.  However, much of the southeastern part of Wutip’s circulation will pass over Hainan.  The increased friction over land will slow the winds in that part of Tropical Storm Wutip.  Typhoon Wutip could intensify a little more during the next few hours.

Tropical Storm Wutip will move around the western part of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Wutip toward the northeast during the next 24 hours.  On its anticipated track, the center Typhoon Wutip will make landfall on the coast of southern China southwest of Lianjiang.

Typhoon Wutip will bring strong winds and heavy rain to southern China on Saturday.  The strongest winds and heaviest rain will occur in Guangdong and eastern Guangxi.  Heavy rain could cause flash floods in some locations.

Tropical Storm Wutip Brings Wind and Rain to Hainan

Tropical Storm Wutip brought wind and rain to Hainan on Thursday night.  At 11:00 p.m. EDT on Thursday the center of Tropical Storm Wutip was located at latitude 18.6°N and longitude 108.5°E which put the center about 40 miles (65 km) south-southwest of Dongfang, China.  Wutip was moving toward the northwest at 9 m.p.h. (15 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. (105 km/h).  The minimum surface pressure was 983 mb.

Tropical Storm Wutip brought wind and rain to Hainan on Thursday night.  The center of Wutip’s circulation was passing just to the west of Hainan.  Bands in the eastern side of Tropical Storm Wutip were bringing strong winds and locally heavy rain to parts of Hainan.

Tropical Storm Wutip intensified on Thursday.  The inner end of a rainband wrapped around the center of Wutip’s circulation.  A small circular eye appeared to be forming at the center of Tropical Storm Wutip.  Bands of showers and thunderstorms were revolving around the center of Wutip’s circulation.  Storms near the center of Wutip generated upper level divergence that pumped mass away from the tropical storm.  The removal of mass caused the surface pressure to decrease.

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

Tropical Storm Wutip will move through an environment that will be generally favorable for intensification during the next 24 hours.  Wutip will move over water where where the Sea Surface Temperatures are near 30°C.  It will move under the axis of an upper level ridge over eastern China.  The upper level winds are weak near the axis of the ridge and there will be little vertical wind shear.  However, much of the eastern side of Wutip’s circulation will pass over Hainan.  The increased friction over land will slow the winds in that part of Tropical Storm Wutip.  Tropical Storm Wutip could intensify to a typhoon during the next 24 hours if the center of Wutip remains over water..

Tropical Storm Wutip will move around the western part of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Wutip toward the north during the next 24 hours.  On its anticipated track, the center Tropical Storm Wutip will pass just to the west of Hainan.  Wutip will approach the coast of Guangxi in 24 hours.

Tropical Storm Wutip will continue to bring strong winds and heavy rain to Hainan on Friday.  Heavy rain could cause flash floods in some locations.  Wutip will also bring strong winds and heavy rain to Guangxi during the weekend.

Tropical Storm Wutip Forms Over South China Sea

Tropical Storm Wutip formed over the South China Sea south of Hainan on Wednesday.  At 5:00 p.m. EDT on Wednesday the center of Tropical Storm Wutip was located at latitude 16.5°N and longitude 110.6°E which put the center about 150 miles (240 km) south of Lingshui, China.  Wutip was moving toward the west at 6 m.p.h. (10 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 993 mb.

A low pressure system over the South China Sea strengthened on Wednesday and the Japan Meteorological Agency designated the system as Tropical Storm Wutip.  The distribution of thunderstorms in Tropical Storm Wutip was asymmetrical.  Thunderstorms were occurring in bands in the southern half of Wutip’s circulation.  Bands in the northern side of Tropical Storm Wutip consisted primarily of showers and lower clouds.  The storms in the southern half of Wutip began to generated upper level divergence that pumped mass away to the west of the tropical storm.

There was a large circulation around Tropical Storm Wutip, but the distribution of wind speeds was asymmetrical.  Winds to tropical storm force extended out 110 miles (170 km) in the southern half of Wutip’s circulation.  The winds in the northern half of Tropical Storm Wutip were blowing at less than tropical storm force.

Tropical Storm Wutip will move through an environment somewhat favorable for intensification during the next 24 hours.  Wutip will move over water where where the Sea Surface Temperatures are near 30°C.  It will move under the southern side of an upper level ridge over eastern China.  The upper level ridge will produce northeasterly winds that will blow toward the top of Wutip’s circulation.  Those winds will cause moderate vertical wind shear.  The vertical wind shear will inhibit intensification but the shear will probably not be enough to prevent intensification.  Tropical Storm Wutip is likely to intensify gradually during the next 24 hours.

Tropical Storm Wutip will move around the western part of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Wutip toward the northwest during the next 24 hours.  On its anticipated track, Tropical Storm Wutip will approach the southwestern part of Hainan in 24 hours.

Tropical Storm Wutip will bring gusty winds and heavy rain to Hainan.  Heavy rain could cause flash floods in some locations.

Man-yi Weakens to a Tropical Storm

Former Typhoon Man-yi weakened to a tropical storm over the South China Sea on Monday.  At 10:00 a.m. EST on Monday the center of Tropical Storm Man-yi was located at latitude 18.6°N and longitude 115.4°E which put the center about 280 miles (450 km) south-southeast of Hong Kong.  Man-yi was moving toward the west-northwest at 10 m.p.h. (16 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 993 mb.

Former Typhoon Man-yii weakened to a tropical storm after it hit Luzon on Sunday.  An eye was no longer present at the center of Man-yi’s circulation.  Bands of showers and thunderstorms were revolving around the center of Tropical Storm Man-yi.  Storms near the center of Man-yi still generated some upper level divergence that pumped mass away to the northeast of the tropical storm.  The removal of mass was less that the amount of mass converging in the lower levels of Tropical Storm Man-yi.  So, the surface pressure was increasing.

The distribution of wind speeds around Tropical Storm Man-yi became more asymmetrical as Man-yi moved over the South China Sea.  Winds to tropical storm force extended out 275 miles (445 km) in the northern side of Man-yi’s circulation.  The large area of tropical storm force winds on the northern side of Tropical Storm Man-yi was partly due to Man-yi’s interaction with a high pressure system over China.  Winds to tropical storm force extended out 150 miles (240 km) in the southern part of Tropical Storm Man-yi.

Tropical Storm Man-yi will move through an environment unfavorable for intensification during the next 24 hours.  Man-yi will move over water where where the Sea Surface Temperatures are near 27°C.  It will move under the eastern side of an upper level trough over China.  The upper level trough will produce southwesterly winds that will blow toward the top of Man-yi’s circulation.  Those winds will cause moderate vertical wind shear.  In addition, the high pressure system over China will transport colder, drier air toward Tropical Storm Man-yi.  The effects of moderate vertical wind shear and colder, drier air will cause Tropical Storm Man-yi to weaken during the next 24 hours.

Tropical Storm Man-yi will move around the southern side of the high pressure system over China.  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 toward Hainan.

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.

Typhoon Yinxing Spins Over the South China Sea

Typhoon Yinxing was spinning over the South China Sea on Friday afternoon.  At 4:00 p.m. EST on Friday the center of Typhoon Yinxing was located at latitude 18.7°N and longitude 115.4°E which put the center about 275 miles (445 km) south-southeast of Hong Kong.  Yinxing was moving toward the west at 13 m.p.h. (20 km/h).  The maximum sustained wind speed was 115 m.p.h. (185 km/h) and there were wind gusts to 145 m.p.h. (230 km/h).  The minimum surface pressure was 969 mb.

Typhoon Yinxing was the equivalent of a major hurricane on Friday afternoon as it spun over the South China Sea.  A circular eye with a diameter of 22 miles (35 km) was that the center of Typhoon Yinxing.  A ring of thunderstorms surrounded the eye and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Yinxing’s circulation.  Storms near the core of Yinxing generated upper level divergence that pumped mass away from the typhoon.

The circulation around Typhoon Yinxing was a little smaller on Friday afternoon.  Winds to typhoon force extended out 50 miles (80 km) from the center of Yinxing’s circulation.  Winds to tropical storm force extended out 150 miles (240 km) from the center of Typhoon Yinxing.

The Hurricane Intensity Index (HII) for Typhoon Yinxing was 20.6. The Hurricane Size Index (HSI) was 18.1 and the Hurricane Wind Intensity Size Index (HWISI) was 38.7.  Typhoon Yinxing was similar in intensity to Hurricane Delta when Delta hit Louisiana in 2020.  Yinxing is bigger than Delta was.

Typhoon Yinxing will move through an environment that will become unfavorable for intensification during the next 24 hours.  Yinxing will move over water where the Sea Surface Temperatures are near 29°C.  It will move under 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.  However, a high pressure system over China will circulate drier air toward the northwestern part of Typhoon Yinxing.  The drier air will begin to be pulled into the northwestern part of Yinxing’s circulation.  The drier air will cause the thunderstorms in the part of Typhoon Yinxing.  The drier air is likely to cause Typhoon Yinxing to weaken during the next 24 hours.

Typhoon Yinxing will move around the southern part of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Yinxing toward the west during the next 24 hours.  On its anticipated track, Typhoon Yinxing will move pass south of Hong Kong during the next 24 hours.
