Typhoon Yinxing Intensifies to Equivalent of a Major Hurricane

Typhoon Yinxing intensified to the equivalent of a major hurricane over the Western North Pacific Ocean east of northern Luzon on Wednesday morning.  At 10:00 a.m. EST on Wednesday the center of Typhoon Yinxing was located at latitude 18.2°N and longitude 123.7°E which put the center about 135 miles (220 km) east of Aparri, Philippines.  Yinxing was moving toward the west at 5 m.p.h. (8 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. (235 km/h).  The minimum surface pressure was 958 mb.

Typhoon Yinxing intensified to the equivalent of a major hurricane east of Luzon on Wednesday morning.  A circular eye was at the center of Yinxing’s circulation.  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 Typhoon Yinxing.  Storms near the core generated upper level divergence that pumped mass away from the typhoon.  The removal of mass caused the surface pressure to decrease.

The circulation around Typhoon Yinxing was large.  Winds to typhoon force extended out 40 miles from the center of Yinxing’s circulation.  Winds to tropical storm force extended out 215 miles (345 km) from the center of Typhoon Yinxing.

The Hurricane Intensity Index (HII) for Typhoon Yinxing was 20.6.  The Hurricane Size Index (HSI) was 13.6 and the Hurricane Wind Intensity Size Index (HWISI) was 34.2.  Typhoon Yinxing was similar in size and intensity to Hurricane Delta when Delta hit Louisiana in 2020.

Typhoon Yinxing will move through an environment favorable for intensification during the next 12 hours.  Yinxing will move over water where the Sea Surface Temperatures are near 30°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.  Typhoon Yinxing will intensify during the next 12 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 reach northern Luzon in 18 hours.

Typhoon Yinxing will bring strong, gusty winds and heavy rain to northern Luzon.  Heavy rain will cause flash floods and mudslides.  Yinxing will cause widespread power outages.  Typhoon Yinxing could cause a storm surge of up to 10 feet (3 meters) along the coast of northern Luzon.  Yinxing will be capable of causing regional major damage.

Yinxing Strengthens to a Typhoon

Former Tropical Storm Yinxing strengthened to a typhoon over the Western North Pacific Ocean east of the Philippines.  At 10:00 a.m. EST on Monday the center of Typhoon Yinxing was located at latitude 14.8°N and longitude 129.5°W which put the center about 610 miles (980 km) east of Manila, Philippines.  Yinxing was moving toward the northwest at 21 m.p.h. (33 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 987 mb.

Former Tropical Storm Yinxing strengthened to a typhoon east of the Philippines on Monday.  The inner end of a rainband wrapped around the center of Yinxing’s circulation.  An eye appeared to be forming at the center of Typhoon Yinxing.  Bands of showers and thunderstorms were revolving around the center of circulation.  Storms near the center of Yinxing generated upper level divergence that pumped mass away from the typhoon.

Winds to typhoon force extended out 35 miles in the eastern side of Typhoon Yinxing.  Winds to tropical storm force extended out 165 miles (265 km) from the center of Yinxing’s circulation.

Typhoon Yinxing will move through an environment favorable for intensification during the next 24 hours.  Yinxing will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the southwestern part of an upper level ridge over the Western North Pacific Ocean.  The upper level ridge will produce southeasterly winds that will blow toward the top of Yinxing’s 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 Yinxing will intensify during the next 24 hours.

Typhoon Yinxing will move around the southwestern part of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Yinxing toward the northwest during the next 24 hours.  On its anticipated track, Typhoon Yinxing will move toward the northern Philippines.  Yinxing could approach northern Luzon in three days.

Tropical Storm Trami Moves Over South China Sea

Tropical Storm Trami moved over the South China Sea on Thursday.  At 11:00 p.m. EDT on Thursday the center of Tropical Storm Trami was located at latitude 17.0°N and longitude 118.3°E which put the center about 215 miles (350 km) northwest of Manila, Philippines.  Trami was moving toward the west at 6 m.p.h.

A low pressure system over the Western North Pacific Ocean east of the Philippines strengthened on Monday night and the Japan Meteorological Agency designated the system as Tropical Storm Trami.  The distribution of thunderstorms in Tropical Storm Trami was asymmetrical.  Thunderstorms were occurring in bands in the western side of Trami’s circulation.  Bands in the eastern side of Tropical Storm Trami consisted primarily of showers and lower clouds.  Storms near the center of Trami’s circulation began to generate upper level divergence that pumped mass away from the tropical storm.

The circulation around Tropical Storm Trami was large.  Winds to tropical storm force extended out 165 miles (265 km) from the center of Trami’s circulation.

Tropical Storm Trami will move through an environment somewhat favorable for intensification during the next 24 hours.  Trami will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the southern part of an upper level ridge over the Western North Pacific Ocean.  The upper level ridge will produce easterly winds that will blow toward the top of Trami’s 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 Trami will intensify during the next 24 hours.

Tropical Storm Trami will move around the southern side of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Trami toward the northwest during the next 24 hours.  On its anticipated track, Tropical Storm Trami will approach northern Luzon in 36 hours.

Tropical Storm Trami will bring strong winds and heavy rain to parts of Luzon.  Heavy rain is likely to cause flash floods in some locations.

Tropical Storm Yagi Drops Heavy Rain on Northern Luzon

Tropical Storm Yagi dropped heavy rain on parts of northern Luzon on Monday.  At 11:00 a.m. EDT on Monday the center of Tropical Storm Yagi was located at latitude 17.5°N and longitude 121.7°E which put the center about 25 miles (40 km) south of Tuguegarao, Philippines.  Yagi was moving toward the north-northwest at 9 m.p.h. (15 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 996 mb.

The center of Tropical Storm Yagi moved across northern Luzon on Monday.  Storms near the center of Yagi’s circulation dropped heavy rain on parts of northern Luzon.  There were reports that heavy rain caused floods and landslides in some locations.  There were also reports that the floods and landslides caused an unknown number of deaths.

The circulation around Tropical Storm Yagi weakened gradually as Yagi move across northern Luzon.  Thunderstorms were still occurring near the center of Yagi’s circulation.  Thunderstorms were also occurring in bands revolving around the center of circulation.  Storms near the center of Yagi generated upper level divergence that pumped mass away from the tropical storm.

Winds to tropical storm force extended out 70 miles (110 km) from the center of Tropical Storm Yagi.

Tropical Storm Yagi will move around the western part of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Yagi toward the northwest during the next 24 hours.  On its anticipated track, the center of Tropical Storm Yagi will move over the South China Sea in 12 hours.  A second high pressure system that is over China will steer Yagi toward the west on Tuesday.

Tropical Storm Yagi will continue to weaken gradually during the next few hours while it moves across northern Luzon.  Yagi will move into an environment that will be favorable for intensification when it moves over the South China Sea.  Yagi will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the middle of an upper level ridge over the South China Sea.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Tropical Storm Yagi is likely to intensify after it moves over the South China Sea.  Yagi is likely to strengthen to a typhoon by the middle of the week.

Tropical Storm Yagi will continue to drop heavy rain over northern Luzon during the next few hours.  Heavy rain is likely to cause additional floods and landslides.

Tropical Storm Yagi Forms Near the Northern Philippines

Tropical Storm Yagi formed near the northern Philippines on Sunday.  At 11:00 a.m. EDT on Sunday the center of Tropical Storm Yagi was located at latitude 13.9°N and longitude 124.4°E which put the center about 40 miles (65 km) northeast of Virac, Philippines.  Yagi was moving toward the northwest at 13 m.p.h. (20 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 pressure system near the northern Philippines strengthened on Sunday morning and the Japan Meteorological Agency designated the system as Tropical Storm Yagi.  The center of Yagi’s circulation was near Catanduanes Island.  Thunderstorms were forming near the center of Tropical Storm Yagi.  However, the distribution of thunderstorms in Yagi was asymmetrical.  Thunderstorms were forming in bands in the western half of Yagi’s circulation.  Bands in the eastern half of Tropical Storm Yagi consisted primarily of showers and lower clouds.  Storms near the center of Yagi began to generate upper level divergence that pumped mass away from the tropical storm.

Tropical Storm Yagi will move through an environment that will be mostly favorable for intensification during the next 24 hours.  Yagi will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the southern part of an upper level ridge over the Western North Pacific Ocean.  The upper level ridge will produce easterly winds that will blow toward the top of Yagi’s circulation.  Those winds will cause moderate vertical wind shear.  The wind shear will inhibit intensification, but the shear will not be enough to prevent Yagi from strengthening.  Tropical Storm Yagi is likely to intensify during the next 24 hours.

Tropical Storm Yagi will move around the western part of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Yagi toward the north-northwest during the next 24 hours.  On its anticipated track, the center of Tropical Storm Yagi will move near the east coast of Luzon.  A second high pressure system that is over China will steer Yagi toward the west early next week.

Bands in the western side of Tropical Storm Yagi will drop heavy rain over parts of Luzon.  Heavy rain is likely to cause widespread flooding.

Tropical Storm Prapiroon Brings Wind and Rain to Hainan

Tropical Storm Prapiroon brought wind and rain to Hainan on Sunday.  At 5:00 p.m. EDT on Sunday the center of Tropical Storm Prapiroon was located at latitude 19.1°N and longitude 109.9°E which put the center about 65 miles (105 km) south-southwest of Haikou, China.  Prapiroon was moving toward the northwest at 13 m.p.h. (21 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 992 mb.

Tropical Storm Prapiroon intensified on Sunday before the center moved over Hainan.  Microwave satellite images indicated that an eye was in the process of forming at the center of Prapiroon’s circulation as the tropical storm made landfall in Hainan.  The formative 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 center of Tropical Storm Prapiroon.

Winds to tropical storm force extended out 70 miles (110 km) from the center of Tropical Storm Prapiroon.

The center of Tropical Storm Prapiroon made landfall on the south coast of Hainan near Lingshui.  The core of Prapiroon’s circulation moved across the center of Hainan.  Storms near the center of Tropical Storm Prapiroon brought heavy rain and strong winds to much of Hainan.  Bands in the northern part of Hainan’s circulation were also bringing gusty winds and heavy rain to parts of southern China.

Tropical Storm Prapiroon will move around the southern side of a high pressure system over southern China.  The high pressure system will steer Prapiroon toward the northwest during the next 24 hours.  On its anticipated track Tropical Storm Prapiroon will move over the Gulf of Tonkin on Monday.  The center of Prapiroon’s circulation could approach the southern coast of China in 24 hours.

Tropical Storm Prapiroon will continue to cause strong winds and locally heavy rain in Hainan during the next few hours.  Heavy rain could cause flash floods in some locations.  Prapiroon will also bring gusty winds and heavy rain to parts of southern China and northeastern Vietnam.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Gaemi strengthened east of Luzon.  At 5:00 p.m. EDT on Sunday the center of Tropical Storm Gaemi was located at latitude 17.2°N and longitude 125.7°E which put the center about 525 miles (845 km) south of Ishigakijima, Japan.  Gaemi was moving toward the north-northwest at 3 m.p.h. (5 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 992 mb.

Typhoon Ewiniar Moves Away From Luzon

Typhoon Ewiniar moved away from Luzon on Monday. At 11:00 a.m. EDT on Monday the center of Typhoon Ewiniar was located at latitude 17.4°N and longitude 124.3°E which put it about 185 miles (300 km) east of Tuguegarao, Philippines. Ewiniar was moving toward the northeast at 9 m.p.h. (15 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 966 mb.

After intensifying rapidly on Sunday, Typhoon Ewiniar showed signs of weakening on Monday. A small eye with a diameter of 5 miles (8 km) was still present at the center of Ewiniar’s circulation. However, there were breaks in the ring of thunderstorms surrounding the eye. Storms near the center of Ewiniar still were generating upper level divergence that was pumping mass away from the typhoon. Bands of showers and thunderstorms were revolving around the center of Typhoon Ewiniar.

The circulation around Typhoon Ewiniar was small. Winds to typhoon force extended out 20 miles (30 km) from the center of Ewiniar’s circulation. Winds to tropical storm force extended out 75 miles (120 km) from the center of circulation.

Typhoon Ewiniar will move through an environment that will become less favorable for intensification during the next 24 hours. Ewiniar will move over water where the Sea Surface Temperatures are near 30°C. An upper level trough near the east coast of China will produce southwesterly winds that will blow toward the top of Ewiniar’s circulation. Those winds will cause the vertical wind shear to increase. Since the circulation around Ewiniar is small, an increase in wind shear will have a larger effect on the typhoon. Typhoon Ewiniar is likely to weaken during the next 24 hours when the vertical wind shear increases.

Typhoon Ewiniar will move around the northwestern part of a high pressure system over the Western North Pacific Ocean. The high pressure system and the upper level trough near the east coast of China will steer Ewiniar toward the northeast during the next 24 hours. On its anticipated track, Typhoon Ewiniar will continue to move farther away from Luzon. Ewiniar will pass southeast of the Ryukyu Islands during the next few days.

Elsewhere, Tropical Cyclone Remal continued to drop heavy rain on Bangladesh. There were reports that Remal caused fatalities in Bangladesh. At 5:00 a.m. EDT on Monday the center of Tropical Cyclone Remal was located at latitude 23.1°N and longitude 89.2°E which put it about 85 miles (140 km) southwest of Dhaka, Bangladesh. Remal was moving toward the north-northeast at 5 m.p.h. (8 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 979 mb.

Ewiniar Rapidly Intensifies to a Typhoon East of Luzon

Former Tropical Storm Ewiniar rapidly intensified to a typhoon east of Luzon on Sunday. At 11:00 a.m. EDT on Sunday the center of Typhoon Ewiniar was located at latitude 15.2°N and longitude 122.5°E which put it about 125 miles (200 km) east-northeast of Manila, Philippines. Ewiniar was moving toward the northeast at 7 m.p.h. (11 km/h). The maximum sustained wind speed was 90 m.p.h. (145 km/h) and there were wind gusts to 115 m.p.h. (185 km/h). The minimum surface pressure was 966 mb.

Former Tropical Storm Ewiniar rapidly intensified to a typhoon after it moved east of Luzon on Sunday. A very small eye with a diameter of 5 miles (8 km) formed at the center of Typhoon Ewiniar. 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 center of Ewiniar’s circulation. Storms near the center generated upper level divergence that pumped mass away from the typhoon. The removal of mass caused the surface pressure to decrease rapidly.

The circulation around Typhoon Ewiniar was small. Winds to typhoon force extended out 20 miles (30 km) from the center of Ewiniar’s circulation. Winds to tropical storm force extended out 60 miles (95 km) from the center of circulation.

Typhoon Ewiniar will move through an environment that will be very favorable for intensification during the next 24 hours. Ewiniar will move over water where the Sea Surface Temperatures are near 31°C. It will move under the western part of an upper level ridge over the Western North Pacific Ocean. The upper level ridge will produce southwesterly winds that will blow toward the top of Ewiniar’s circulation. The winds in the lower levels of the atmosphere will also blow from the southwest and there will be little vertical wind shear. Typhoon Ewiniar is likely to intensify during the next 24 hours. Ewiniar could continue to intensify rapidly. If the inner end of a rainband wraps around the existing eye and eyewall, then an eyewall replacement cycle could interrupt the intensification.

Typhoon Ewiniar will move around the western end of a high pressure system that is east of the Philippines. The high pressure system will steer Ewiniar toward the northeast during the next 24 hours. On its anticipated track, Typhoon Ewiniar will move farther away from Luzon during the next 24 hours. Ewiniar will pass southeast of the Ryukyu Islands during the early part of next week.

Typhoon Ewiniar will continue to produce strong winds and locally heavy rain in Luzon until it moves farther to the northeast. Heavy rain is likely to cause flash floods in some locations.
