Tropical Storm Danas Drops Rain on Eastern China

Tropical Storm Danas dropped rain on eastern China on Tuesday.  At 5:00 p.m. EDT on Tuesday the center of Tropical Storm Danas was located at latitude 27.6°N and longitude 120.3°E which put the center about 50 miles (80 km) southwest of Wenzhou, China.  Danas was moving toward the west-southwest 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 986 mb.

The center of Tropical Storm Danas made landfall on the east coast of China just to the south of Wenzhou on Tuesday.  The maximum sustained wind speed was 40 m.p.h. (65 km/h) at the time of landfall.  Winds to tropical storm force extended out 120 miles (195 km) from the center of Danas’ circulation.

Tropical Storm Danas will move around the southern side of a high pressure system over eastern Asia.  The high pressure system will steer Danas toward the southwest during the next 24 hours.  On its anticipated track, Tropical Storm Danas will move farther inland over eastern China.

Tropical Storm Danas will weaken gradually as it moves inland over eastern China.  The heaviest rain will be produced by bands in the southern side of Danas’ circulation.  Bands in the northern side of Tropical Storm Danas will consist primarily of showers and lower clouds.

Tropical Storm Danas will drop heavy rain over parts of Zhejiang.  Heavy rain could cause floods in some locations.

The strongest winds will occur in the eastern side of Danas’ circulation which will be over the East China Sea.  Most of the winds over land will be at less than tropical storm force.

Tropical Storm Danas Nears Eastern China

Tropical Storm Danas was nearing eastern China on Monday evening.  At 11:00 p.m. EDT on Monday the center of Tropical Storm Danas was located at latitude 28.1°N and longitude 122.0°E which put the center about 80 miles (130 km) east of Wenzhou, China and about 50 miles (80 km) southeast of Taizhou, China.  Danas was moving toward the north 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 992 mb.

Even though Tropical Storm Danas was over the East China Sea on Monday, Danas’ circulation was still disrupted from the affects of its passage over Taiwan on Sunday.  The distribution of thunderstorms in Tropical Storm Danas was asymmetrical.  Thunderstorms were occurring in bands in the southern part of Danas’ circulation.  Bands in the northern side of Tropical Storm Danas consisted primarily of showers and lower clouds.

Winds to tropical storm force extended out 90 miles (145 km) from the center of Tropical Storm Danas.

Tropical Storm Danas will move through an environment that will be somewhat favorable for intensification during the next few hours. Danas will move over water where where the Sea Surface Temperatures are near 29°C.  It will move under the middle of an upper level ridge over East China Sea.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Even though Tropical Storm Danas will move through a somewhat favorable environment, Danas may not intensify because of the disruption of its circulation during the passage over Taiwan.

Tropical Storm Danas will move around the southern side of a high pressure system over eastern Asia.  The high pressure system will steer Danas toward the west during the next 24 hours.  On its anticipated track, Tropical Storm Danas will move over eastern China in a few hours.

The center of Tropical Storm Danas is likely to make landfall in China between Taizhou and Wenzhou.  Danas will bring gusty winds and locally heavy rain to Zhejiang.  Heavy rain could cause floods in some locations.

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.

Typhoon Danas Hits Taiwan

Typhoon Danas hit Taiwan on Sunday.  At 11:00 a.m. EDT on Sunday the center of Typhoon Danas was located at latitude 23.5°N and longitude 120.0°E which put the center about 75 miles (120 km) southwest of Taichung, Taiwan.  Danas was moving toward the northeast 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 Danas rapidly intensified to the equivalent of a Category 2 hurricane on the Saffir-Simpson Scale as it approached Taiwan on Sunday.  The inner end of a rainband wrapped around the center of Danas’ circulation.  A circular eye with a diameter of 16 miles (26 km) formed at the center of Typhoon Danas.  Other bands of showers and thunderstorms were revolving around the core of Danas’ circulation.

The size of the circulation around Typhoon Danas increased when Danas rapidly intensified.  Winds to typhoon force extended out 35 miles (55 km) from the center of Danas’ circulation.  Winds to tropical storm force extended out 160 miles (260 km) in the eastern side of Typhoon Danas.  Winds to tropical storm force extended out 85 miles (135 km) in the western side of Danas.

The Hurricane Intensity Index (HII) for Typhoon Danas is 17.8.  The Hurricane Size Index (HSI) is 14.4 and the Hurricane Wind Intensity Size Index (HWISI) is 32.2.  Typhoon Danas is similar in size and intensity to Hurricane Sally when Sally hit Alabama in 2020.

Typhoon Danas will bring strong, gusty winds and heavy rain to Taiwan.  Heavy rain is likely to cause flash floods and mudslides.  Widespread outages of electricity are possible.  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 of Japan.  At 11:00 a.m. EDT on Sunday the center of Tropical Storm Mun was located at latitude 33.9°N and longitude 149.4°E which put the center about 545 miles (875 km) east of Tokyo, Japan.  Mun was moving toward the north 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 982 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 Mun Spins Southeast of Japan

Tropical Storm Mun was spinning over the Western North Pacific Ocean southeast of Japan on Thursday evening.  At 11:00 p.m. EDT on Thursday the center of Tropical Storm Mun was located at latitude 29.9°N and longitude 144.9°E which put the center about 495 miles (795 km) southeast of Tokyo, Japan.  Mun was moving toward the north at 7 m.p.h. (11 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.

Tropical Storm Mun strengthened on Thursday as it spun over the Western North Pacific Ocean southeast of Japan.  The circulation around Tropical Storm Mun became more symmetrical.  More thunderstorms developed near the center of Mun’s circulation.  Thunderstorms were also occurring in bands revolving around the center of Tropical Storm Mun.  Storms near the center of Mun 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 Mun was small.  Winds to tropical storm force extended out 60 miles (95 km) from the center of Mun’s circulation.

Tropical Storm Mun will move through an environment that will be favorable for intensification during the next 24 hours.  Mun will move over water where where the Sea Surface Temperatures are near 27°C.  An upper level low south of Japan will produce southwesterly winds that will blow toward the top of Mun’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 Mun is likely to intensify during the next 24 hours.  Mun could strengthen to a typhoon.

Tropical Storm Mun will move around the western end of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Mun toward the northeast during the next 24 hours.  On its anticipated track, Tropical Storm Mun will move farther away from Honshu.

Elsewhere over the Western North Pacific Ocean, Tropical Depression 05W formed south of Taiwan.  At 11:00 p.m. EDT on Thursday the center of Tropical Depression 05W was located at latitude 19.7°N and longitude 118.6°E which put the center about 305 miles (495 km) south-southwest of Kaohsiung, Taiwan.  The tropical depression was moving toward the west-southwest at 7 m.p.h. (11 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 1001 mb.

Tropical Storm Gaemi Brings Wind and Rain to Eastern China

Tropical Storm Gaemi brought wind and rain to parts of eastern China on Thursday.  At 11:00 a.m. EDT on Thursday the center of Tropical Storm Gaemi was located at latitude 25.9°N and longitude 119.1°E which put the center about 25 miles (40 km) west of Fuzhou, China.  Gaemi was moving toward the northwest at 6 m.p.h. (10 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 973 mb.

Former Typhoon Gaemi weakened to a tropical storm on Thursday before it made landfall on the east coast of China.  The center of Gaemi’s circulation made landfall southeast of Fuzhou near Fuqing.  Showers and thunderstorms in bands in the eastern and southern parts of Tropical Storm Gaemi were dropping heavy rain.  The bands in the northern and western parts of Gaemi’s circulation consisted primarily of showers and lower clouds.

The circulation around Tropical Storm Gaemi was large.  Winds to tropical storm force extended out 220 miles (350 km) from the center of Gaemi’s circulation.  The strongest winds were occurring in bands that were still over water in the eastern and southern parts of Tropical Storm Gaemi.

Tropical Storm Gaemi will move toward the northwest during the next 24 hours.  Gaemi will weaken as it moves farther inland over eastern China.  Tropical Storm Gaemi will drop heavy rain over parts of Fujian, Jiangxi and Zhejiang.  Heavy rain is likely to cause floods in some locations.

Typhoon Gaemi Batters Taiwan

Typhoon Gaemi battered Taiwan on Wednesday.  At 11:00 a.m. EDT on Wednesday the center of Typhoon Gaemi was located at latitude 24.0°N and longitude 121.4°E which put the center about 100 miles (160 km) south of Taipei, Taiwan.  Gaemi was moving toward the northwest at 8 m.p.h. (13 km/h).  The maximum sustained wind speed was 125 m.p.h. (200 km/h) and there were wind gusts to 155 m.p.h. (250 km/h).  The minimum surface pressure was 928 mb.

The inner end of a rainband wrapped around the existing eye and eyewall of Typhoon Gaemi as it approached the east coast of Taiwan.  Concentric eyewalls formed in the core of Gaemi’s circulation.  The diameter of the inner eye was 7 miles (11 km).  The inner 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 Gaemi.

The inner eye of Typhoon Gaemi began to make a counterclockwise loop inside the outer eyewall as Gaemi neared the east coast of Taiwan.  Mountains in Taiwan also deflected winds blowing around the western side of Typhoon Gaemi.  The deflection of the winds by the mountains also contributed to the counterclockwise loop of the inner eye.  The inner eye made landfall near Yilan City after it completed the counterclockwise loop.

The circulation around Typhoon Gaemi was large.  Winds to typhoon force extended out 105 miles (165 km) from the center of Gaemi’s circulation.  Winds to tropical storm force extended out 315 miles (510 km) from the center of Typhoon Gaemi.

Typhoon Gaemi was the equivalent of a major hurricane at the time of landfall.  The Hurricane Intensity Index (HII) was 23.6.  The Hurricane Size Index (HSI) was 35.2 and the Hurricane Wind Intensity Size Index (HWISI) was 58.8.  Typhoon Gaemi was as strong as Hurricane Katrina was when Katrina made landfall on the coast of the Gulf of Mexico in 2005.  Gaemi was larger than Katrina was when Katrina made landfall.

Typhoon Gamei was producing strong winds in Taiwan.  Gaemi was also dropping very heavy rain over parts of Taiwan.  Prolonged heavy rain is likely to cause flash floods in many locations.  Typhoon Gaemi was also causing a storm surge of up to 13 feet (4 meters) along the coast of northern Taiwan where the wind was blowing water toward the coast.

Typhoon Gaemi will move toward the northwest during the next 24 hours.  Gaemi will continue to produce strong winds and heavy rain in Taiwan for another 12 to 24 hours.  The center of Typhoon Gaemi will move over the Taiwan Strait in a few hours.  Gaemi will make another landfall on the east coast of China in about 18 hours.

Typhoon Gaemi Strengthens to Equivalent of a Major Hurricane

Typhoon Gaemi strengthened to the equivalent of a major hurricane east of Taiwan on Tuesday.  At 5:00 p.m. EDT on Tuesday the center of Typhoon Gaemi was located at latitude 23.1°N and longitude 123.2°E which put the center about 200 miles (325 km) southeast of Taipei, Taiwan.  Gaemi was moving toward the northwest at 15 m.p.h. (24 km/h).  The maximum sustained wind speed was 140 m.p.h. (225 km/h) and there were wind gusts to 165 m.p.h. (265 km/h).  The minimum surface pressure was 948 mb.

Typhoon Gaemi rapidly intensified to the equivalent of a Category 4 hurricane on the Saffir-Simpson Scale east of Taiwan on Tuesday.  A small circular eye with a diameter of 6 miles (10 km) formed at the center of Gaemi’s circulation.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storm.  Bands of showers and thunderstorms were revolving around the core of Typhoon Gaemi.  Storms near the core generated strong upper level divergence that pumped mass away from the typhoon.  The removal of large amounts of mass caused the surface pressure to decrease rapidly.

The circulation around Typhoon Gaemi was large.  Winds to typhoon force extended out 100 miles (160 km) from the center of Gaemi’s circulation.  Winds to tropical storm force extended out 345 miles (555 km) from the center of Typhoon Gaemi.

The Hurricane Intensity Index (HII) for Typhoon Gaemi was 28.3.  The Hurricane Size Index (HSI) was 31.0 and the Hurricane Wind Intensity Size Index (HWISI) was 59.3.  Typhoon Gaemi was similar in size to Hurricane Wilma when Wilma hit South Florida in 2005.  Gaemi is stronger than Wilma was when it hit South Florida.

Typhoon Gaemi will move through an environment favorable for intensification during the next 12 hours.  Gaemi 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 Gaemi could continue to intensify during the next 12 hours.

Typhoon Gaemi will move around the western part of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Typhoon Gaemi toward the northwest during the next 24 hours.  On its anticipated track, Typhoon Gaemi will approach the coast of northeastern Taiwan in 12 hours.

Typhoon Gaemi will bring very strong winds and torrential rain to Taiwan.  Gaemi will be capable of causing extensive severe damage.  Heavy rain is likely to cause widespread flash floods.  Typhoon Gaemi will also be capable of causing a storm surge of up to 13 feet (4 meters) along the east coast of Taiwan.

Typhoon Gaemi will also bring strong winds and heavy rain to the southern Ryukyu Islands.  The strongest part Gaemi’s circulation will pass southwest of the Ryukyu Islands, but the typhoon is likely to some wind damage.  Heavy rain could cause flash floods in some locations.

Typhoon Gaemi will move toward the east coast of China after is crosses northern Taiwan.  Gaemi could approach the coast of China in less than 36 hours.  Typhoon Gaemi will weaken when it moves over Taiwan, but Gaemi could still be a typhoon when it reaches China.

Elsewhere, former Tropical Storm Prapiroon weakened to a tropical depression over northern Vietnam.  At 11:00 a.m. EDT on Tuesday the center of Tropical Depression Prapiroon was located at latitude 22.0°N and longitude 107.0°E which put the center about 25 miles (40 km) northeast of Lang Son, Vietnam.  Prapiroon was moving toward the north-northwest at 5 m.p.h. (8 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 994 mb.
