Typhoon Podul Nears Taiwan

Typhoon Podul was nearing southern Taiwan on Tuesday.  At 5:00 p.m. EDT on Tuesday the center of Typhoon Podul was located at latitude 22.3°N and longitude 122.6°E which put the center about 100 miles (160 km) east-southeast of Taitung, Taiwan.  Podul was moving toward the west-northwest at 17 m.p.h. (28 km/h).  The maximum sustained wind speed was 100 m.p.h. (160 km/h) and there were wind gusts to 120 m.p.h. (195 km/h).  The minimum surface pressure was 970 mb.

Typhoon Podul was intensifying as it approached southern Taiwan on Tuesday.  A circular eye with a diameter of 30 miles (48 km) was at the center of Podul’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 Podul.  Storms near the center generated upper level divergence that pumped mass away to the south and west of the typhoon.  The removal of mass caused the surface pressure to decrease.

The size of the circulation around Typhoon Podul increased as Podul intensified on Tuesday.  Winds to typhoon force extended out 60 miles (95 km) from the center of Podul’s circulation.  Winds to tropical storm force extended out 150 miles (240 km) from the center of Typhoon Podul.

The Hurricane Intensity Index (HII) for Typhoon Podul is 16.5.  The Hurricane Size Index (HSI) is 16.7 and the Hurricane Wind Intensity Size Index (HWISI) is 33.2.  Typhoon Podul is similar in intensity to Hurricane Idalia when Idalia hit Florida in 2023.  Typhoon Podul is much larger than Idalia was.

Typhoon Podul will move through an environment that will be mostly favorable for intensification during the next few hours.  Podul will move over water where the Sea Surface Temperatures are near 29°C.  An upper level ridge over eastern China will produce northeasterly winds that will blow toward the top of Podul’s circulation.  Those winds will cause moderate vertical wind shear. The vertical wind shear will inhibit intensification, but the shear may not be enough to prevent intensification.  Typhoon Podul could continue to intensify during the next few hours.

Typhoon Podul will move around the southern side of a high pressure system that is south of Japan.  The high pressure system will steer Podul toward the west-northwest during the next 24 hours.  On its anticipated track, Typhoon Podul will make landfall in southeastern Taiwan in a few hours.

Typhoon Podul will bring strong gusty winds and heavy rain to Taiwan.  The heaviest rain will fall in southern Taiwan and on the eastern slopes of mountains in eastern Taiwan.  Heavy rain is likely to cause flash floods in some locations.

The Taiwan Central Weather Administration has issued a Land Typhoon Warning for much of Taiwan.  A Sea Typhoon Warning is in effect for much of the waters surrounding Taiwan.

The Taiwan Central Weather Administration has issued an Extremely Heavy Rain Advisory for much of southern and eastern Taiwan.

Typhoon Podul could also cause a storm surge of up to 10 feet (3 meters) along parts of the east coast of Taiwan.

Podul Strengthens to a Typhoon

Former Tropical Storm Podul strengthened to a typhoon over the Western North Pacific Ocean east-southeast of Taiwan on Monday.  At 5:00 p.m. EDT on Monday the center of Typhoon Podul was located at latitude 20.8°N and longitude 128.6°E which put the center about 510 miles (825 km) east-southeast of Taipei, Taiwan.  Podul was moving toward the west at 16 m.p.h. (26 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 984 mb.

The circulation around Typhoon Podul became more symmetrical on Monday.  A circular eye appeared at the center of Podul’s circulation.  The eye was surrounded by a broken ring of thunderstorms.  The strongest winds were occurring in that broken ring of storms.  Bands of showers and thunderstorms were revolving around the center of Typhoon Podul.  Storms near the center of Podul generated upper level divergence that pumped mass away from the typhoon.  The removal of mass caused the surface pressure to decrease.

The strongest winds were occurring in the eastern side of Typhoon Podul.  Winds to typhoon force extended out 35 miles (55 km) in the eastern side of Podul’s circulation.  Winds to tropical storm force extended out 105 miles (165 km) from the center of Typhoon Podul.

Typhoon Podul will move through an environment that will be somewhat favorable for intensification during the next 24 hours.  Podul will move over water where the Sea Surface Temperatures are near 29°C.  However, an upper level ridge over eastern China and Japan will produce northeasterly winds that will blow toward the top of Podul’s circulation.  Those winds will cause moderate vertical wind shear.  The vertical wind shear will inhibit intensification, but the shear may not be enough to prevent intensification.  Typhoon Podul could intensify during the next 24 hours if the wind shear does not get any stronger.

Typhoon Podul will move around the southern side of a high pressure system that is south of Japan.  The high pressure system will steer Podul toward the west-northwest during the next 24 hours.  On its anticipated track, Typhoon Podul will approach Taiwan in 24 hours.

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

Tropical Storm Podul Churns Westward

Tropical Storm Podul churned westward over the Western North Pacific Ocean on Sunday.  At 11:00 p.m. EDT on Sunday the center of Tropical Storm Podul was located at latitude 21.2°N and longitude 132.7°E which put the center about 510 miles (820 km) southeast of Okinawa.  Podul was moving toward the west at 14 m.p.h. (22 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 990 mb.

The structure of Tropical Storm Podul did not change much on Sunday.  An upper level ridge over China and Japan continue to produce northeasterly winds that blew toward the top of Podul’s circulation.  Those winds caused moderate vertical wind shear.  The wind shear was caused the distribution of thunderstorms in Tropical Storm Podul to be asymmetrical.  Thunderstorms were occurring in bands in the southern half of Podul’s circulation.  Bands in the northern side of Tropical Storm Podul consisted primarily of showers and lower clouds.

The circulation around Tropical Storm Podul was small.  Winds to tropical storm force extended out 75 miles (120 km) from the center of Podul’s circulation.

Tropical Storm Podul will move through an environment that will be somewhat favorable for intensification during the next 24 hours.  Podul will move over water where the Sea Surface Temperatures are near 29°C.  However, the upper level ridge over China and Japan will continue to cause vertical wind shear.  The vertical wind shear will continue to  inhibit intensification.  Tropical Storm Podul could intensify slowly during the next 24 hours if the wind shear does not get any stronger.  Podul could strengthen to a typhoon on Monday.

Tropical Storm Podul will move around the southern side of a high pressure system that is south of Japan. The high pressure system will steer Podul toward the west during the next 24 hours.  On its anticipated track, Tropical Storm Podul will approach the southern Ryukyu Islands in 36 hours.  Podul could approach Taiwan in 48 hours.

Tropical Storm Podul Passes South of Iwo To

Tropical Storm Podul passes south of Iwo To on Saturday.  At 11:00 a.m. EDT on Saturday the center of Tropical Storm Podul was located at latitude 21.6°N and longitude 140.4°E which put the center about 230 miles (370 km) south of Iwo To.  Podul was moving toward the west at 9 m.p.h. (17 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 998 mb.

Tropical Storm Podul was maintaining its intensity on Saturday as it passed south of Iwo To.  An upper level ridge over China and Japan was producing northeasterly winds that were blowing toward the top of Podul’s circulation.  Those winds were causing moderate vertical wind shear.  The wind shear was causing the distribution of thunderstorms in Tropical Storm Podul to be asymmetrical.  Thunderstorms were occurring in bands in the southern half of Podul’s circulation.  Bands in the northern side of Tropical Storm Podul consisted primarily of showers and lower clouds.

The circulation around Tropical Storm Podul was small.  Winds to tropical storm force extended out 105 miles (165 km) from the center of Podul’s circulation.

Tropical Storm Podul will move through an environment that will be somewhat favorable for intensification during the next 24 hours.  Podul will move over water where the Sea Surface Temperatures are near 29°C.  However, the upper level ridge over China and Japan will continue to cause moderate vertical wind shear.  The wind shear will inhibit intensification.  Tropical Storm Podul could intensify slowly during the next 24 hours if the wind shear does not get any stronger.

Tropical Storm Podul will move around the southern side of a high pressure system over Japan.  The high pressure system will steer Podul toward the west during the next 24 hours.  On its anticipated track, Tropical Storm Podul will move toward the southern Ryukyu Islands.

Tropical Storm Podul Forms North of Saipan

Tropical Storm Podul formed over the Western North Pacific Ocean north of Saipan on Thursday.  At 5:00 p.m. EDT on Thursday the center of Tropical Storm Podul was located at latitude 19.7°N and longitude 145.9°E which put the center about 290 miles (470 km) north of Saipan.  Podul was moving toward the northwest at 11 m.p.h. (17 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 1003 mb.

A low pressure system over the Western North Pacific Ocean north of Saipan strengthened on Thursday and the Japan Meteorological Agency designated the system as Tropical Storm Podul.

The circulation around Tropical Storm Podul was small.  Thunderstorms were occurring in bands south and east of the center of Podul’s circulation.  Bands in the rest of Tropical Storm Podul consisted primarily of showers and lower clouds.  Storms near the center of Podul started to generate upper level divergence that was beginning to pump mass away from the tropical storm.

The strongest winds in Tropical Storm Podul were occurring in the thunderstorms southeast of the center of circulation.  Winds to tropical storm force extended out 60 miles (95 km) in the southeastern quadrant of Podul’s circulation.  The winds in the other parts of Tropical Storm Podul were blowing at less than tropical storm force.

Tropical Storm Podul will move through an environment favorable for intensification during the next 24 hours.  Podul 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 south of Japan.  The upper level ridge will produce easterly winds that will blow toward the top of Podul’s circulation.  Those winds will cause some vertical wind shear, but the wind shear will not be enough to prevent intensification.  Tropical Storm Podul will intensify during the next 24 hours.  Podul is likely to strengthen to a typhoon during the weekend.

Tropical Storm Podul will move around the southern side of a high pressure system that is south of Japan.  The high pressure system will steer Podul toward the west during the next 24 hours.  On its anticipated track, Tropical Storm Podul will move away from the Marianas.  Podul could approach Taiwan in a few days.

Tropical Storm Sanba Drops Heavy Rain on Southern China

Tropical Storm Sanba dropped heavy rain on parts of southern China on Thursday. At 5:00 p.m. EDT on Thursday the center of Tropical Storm Sanba was located at latitude 21.3°N and longitude 109.2°E which put it about 25 miles (40 km) southeast of Beihai China. Sanba was moving toward the north-northeast at 8 m.p.h. (13 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 1001 mb.

Tropical Storm Sanba dropped heavy rain on parts of Guangxi and Guangdong in southern China on Thursday. The center of Sanba’s circulation was still over the northeastern Gulf of Tonkin. Much of the northern half of Tropical Storm Sanba was over southern China. Part of the eastern side of Sanba’s circulation was over Hainan. Winds to tropical storm force extended out 60 miles (95 km) from the center of Tropical Storm Sanba.

An upper level trough over eastern Asia and an upper level ridge centered north of the Philippines were interacting to produce southwesterly winds that were blowing toward the top of Sanba’s circulation. Those winds were causing moderate vertical wind shear and they were also causing the distribution of thunderstorms to be asymmetrical. Thunderstorms were occurring in bands in the northern and eastern parts of Tropical Storm Sanba. Bands in the southern and western parts of Sanba’s circulation consisted primarily of showers and lower clouds.

Tropical Storm Sanba will be in an environment that is mostly unfavorable for intensification during the next 24 hours. Sanba will move over water where the Sea Surface Temperatures are near 28°C. The upper level trough over eastern Asia and the upper level ridge north of the Philippines will continue to cause moderate vertical wind shear. Almost half of Sanba’s circulation will be over land and increased friction will slow the wind in those areas. Tropical Storm Sanba is likely to weaken during the next 24 hours even if the center of circulation does not move over southern China.

The movement of Tropical Storm Sanba during the next 24 hours will depend on how strong the vertical wind shear is. If the wind shear is moderate and the upper and lower parts of Sanba’s circulation remain connected, then southwesterly winds will steer Tropical Storm Sanba toward the north-northeast. If Sanba moves north-northeast it will move inland over southern China. If the vertical wind shear gets stronger, then the upper level winds will push the top part of Sanba’s circulation toward the north-northeast. If the wind shear rips the top off of Tropical Storm Sanba, then the lower part of the circulation could meander over the northeastern Gulf of Tonkin during the next 24 hours.

Tropical Storm Sanba will continue to drop heavy rain over southern China during the next 24 hours. Heavy rain will fall on parts of Guangxi and Guangdong. Prolonged heavy rain will cause floods in some locations.

Tropical Storm Sanba Forms East of Vietnam

Tropical Storm Sanba formed over the Gulf of Tonkin east of Vietnam on Wednesday. At 11:00 a.m. EDT on Wednesday the center of Tropical Storm Sanba was located at latitude 18.9°N and longitude 108.2°E which put it about 180 miles (280 km) southeast of Haiphong, Vietnam. Sanba was moving toward the northwest at 9 m.p.h. (15 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 1003 mb.

A low pressure system over the Gulf of Tonkin east of Vietnam strengthened on Wednesday and the Japan Meteorological Agency designated the system as Tropical Storm Sanba. The distribution of thunderstorms in Tropical Storm Sanba was asymmetrical. Many of the thunderstorms were occurring in bands in the eastern side of Sanba’s circulation. Bands in the western part of Tropical Storm Sanba consisted primarily of showers and lower clouds. Storms near the center of Sanba’s circulation generated upper level divergence that pumped mass away to the west and north of the tropical storm. Winds to tropical storm force extended out 50 miles (80 km) in the eastern side of Tropical Storm Sanba. The winds in the western part of Sanba’s circulation were blowing at less than tropical storm force.

Tropical Storm Sanba will move through an environment somewhat favorable for intensification during the next 24 hours. Sanba will move over water where the Sea Surface Temperatures are near 28°C. It will move under the western part of an upper level ridge centered northwest of the Philippines. The upper level ridge will produce southeasterly winds that will blow toward the top of Sanba’s circulation. Those winds will cause some vertical wind shear but the wind shear will not be strong enough to prevent intensification. Some of the air circulating around the eastern side of Tropical Storm Sanba will flow over Hainan. The additional friction caused by the land will cause the air in that part of Sanba’s circulation to slow down. Tropical Storm Sanba could intensify gradually during the next 24 hours.

Tropical Storm Sanba will move around the western part of a high pressure system over the Western North Pacific Ocean. The high pressure system will steer Sanba toward the north-northwest during the next 24 hours. On its anticipated track the center of Tropical Cyclone Sanba will pass west of Hainan. Sanba will move toward northeastern Vietnam.

Bands in the eastern side of Tropical Storm Sanba are already producing gusty winds and locally heavy rain in parts of Hainan. Bands in the western side of Sanba’s circulation are bringing rain showers to parts of northern Vietnam. Tropical Storm Sanba will continue to produce gusty winds and locally heavy rain in parts of Hainan and northern Vietnam. Heavy rain could cause flash floods in some locations.

Tropical Storm Nanmadol brought wind and rain to Japan on Sunday. At 11:00 p.m. EDT on Sunday the center of Tropical Storm Nanmadol was located at latitude 34.5°N and longitude 131.9°E which put it about 30 miles (50 km) west of Hiroshima, Japan. Nanmadol was moving toward the north-northeast at 13 m.p.h. (20 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 976 mb.

Former Typhoon Nanmadol weakened to a strong tropical storm as it moved inland over Kyushu on Sunday. The circulation around Tropical Storm Nanmadol was still large. Winds to tropical storm force extended out 275 miles (445 km) from the center of Nanmadol. The strongest winds and heaviest rain were occurring in band in the eastern and northern parts of Nanmadol. Bands in the southern and western parts of Tropical Storm Nanmadol consisted primarily of showers and lower clouds.

The eye of then Typhoon Nanmadol moved over Kagoshima earlier on Sunday. A weather station in Kagoshima measured a surface pressure of 940.8 mb. The same weather station also measured 7.10 inches (180 mm) of rain. Heavy rain fell over many other locations in Kyushu and there were reports of flash floods in some locations.

An upper level trough northwest of Japan will steer Tropical Storm Nanmadol quickly toward the northeast during the next 36 hours. On its anticipated track Tropical Storm Nanmadol will move over much of Honshu. Nanmadol will bring gusty winds and locally heavy rain to Shikoku and Honshu. Heavy rain could cause flash floods in some locations.
