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 Podul Drops Heavy Rain on Vietnam

Tropical Storm Podul dropped heavy rain on Vietnam on Thursday.  At 2:00 p.m. EDT on Thursday the center of Tropical Storm Podul was located at latitude 17.5°N and longitude 106.5°E which put it about 10 miles (15 km) northwest of Dong Hoi, Vietnam.  Podul was moving toward the west at 21 m.p.h. (34 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.

Tropical Storm Podul made landfall near Dong Hoi, Vietnam on Thursday.  The structure of Podul was very asymmetrical.  Most of the thunderstorms were occurring in the western half of the circulation.  Tropical Storm Podul was moving south of an upper level ridge over eastern Asia.  The ridge was producing strong easterly winds which were blowing across the top of Podul.  Those winds were causing strong vertical wind shear and they were the reason why most of the thunderstorms were in the western half of the circulation.  As a result of the wind shear, heavy rain was already falling over Vietnam even before the center made landfall.

The upper level ridge was steering Tropical Storm Podul rapidly toward the west.  Podul will weaken quickly as it moves farther inland.  Even though Tropical Storm Podul will weaken quickly, heavy rain will fall over portions of Laos and northeastern Thailand on Friday.  Locally heavy rainfall could cause flash floods in parts of Vietnam, Laos and northeastern Thailand.

Tropical Storm Podul Forms East of Luzon

Tropical Storm Podul formed east of Luzon on Monday night.  At 11:00 p.m. EDT on Monday the center of Tropical Storm Podul was located at latitude 15.1°N and longitude 125.2°E which put it about 250 miles (400 km) east of Baler, Philippines.  Podul was moving a little to the north of due west at 25 m.p.h. (40 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 998 mb.

A low level center of circulation in an area of thunderstorms east of Luzon was visible in satellite imagery on Monday night and the Japan Meteorological Agency designated the system as Tropical Storm Podul.  The circulation around Tropical Storm Podul was not well organized.  Many of the thunderstorms were occurring in broken bands west of the center of circulation.  Bands in the eastern half of Podul consisted primarily showers and lower clouds.  Tropical Storm Podul was moving south of an upper level ridge over eastern Asia and the Western North Pacific Ocean.  The ridge was producing easterly winds which were causing moderate vertical wind shear.  The shear was contributing to the poorly organized circulation around Podul.

Tropical Storm Podul will move through an environment mostly unfavorable for intensification during the next 24 hours,  Podul will move over water where the Sea Surface Temperature is near 29°C.  However, the upper level ridge will continue to cause moderate vertical wind shear.  The center will move across northern Luzon and increased friction will weaken the circulation.  Tropical Storm Podul could weaken to a tropical depression when it crosses Luzon.  Podul could strengthen in the middle of the week when it moves west of Luzon and out over the South China Sea.

Tropical Storm Podul will move south of a subtropical ridge over the Western North Pacific Ocean.  The ridge will steer Podul a little to the north of due west during the next few days.  On its anticipated track Tropical Storm Podul will move across northern Luzon on Tuesday. Podul will cause gusty winds and locally heavy rain.  The rain could cause flash floods in some locations.  Tropical Storm Podul will move west of Luzon and over the South China Sea in about 24 hours.  Podul could approach Hainan Island in about 72 hours.
