Typhoon Man-yi Hits Luzon

Powerful Typhoon Man-yi hit Luzon on Sunday morning.  At 4:00 a.m. EST on Sunday the center of Typhoon Man-yi was located at latitude 16.2°N and longitude 121.3°E which put the center about 25 miles (40 km) north of Baler, Philippines.  Man-yi was moving toward the northwest at 15 m.p.h. (24 km/h).  The maximum sustained wind speed was 150 m.p.h. (240 km/h) and there were wind gusts to 185 m.p.h. (295 km/h).  The minimum surface pressure was 933 mb.

The center of Typhoon Man-yi made landfall on the east coast of Luzon near Baler on Sunday morning.  Man-yi was the equivalent of a Category 4 hurricane on the Saffir-Simpson Scale at the time of landfall.  A circular eye with a diameter of 17 miles (28 km) was at the center of Typhoon Man-yi.  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 core of Man-yi’s circulation.

The circulation around Typhoon Man-yi was very symmetrical.  Winds to typhoon force extended out 40 miles (65 km) from the center of Man-yi’s circulation.  Winds to tropical storm force extended out 130 miles (210 km) from the center of Typhoon Man-yi.

The Hurricane Intensity Index (HII) for Typhoon Man-yi was 31.6.  The Hurricane Size Index (HSI) was 16.0 and the Hurricane Wind Intensity Size Index (HWISI) was 47.6. Typhoon Man-yi was similar in size and intensity to Hurricane Laura when Laura hit Southwest Louisiana in 2020.

Typhoon Man-yi will move around the southern side of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Man-yi toward the northwest during the next 24 hours.  On its anticipated track, Typhoon Man-yi will move across Luzon during the rest of today.

Typhoon Man-yi will also bring very strong winds and heavy rain to Luzon. Heavy rain will cause flash floods and mudslides.  Man-yi could also cause a storm surge of up to 13 feet (4 meters) along the coast of Luzon.  Luzon has already been hit by a series of in recent weeks. Typhoon Man-yi is capable of causing regional severe damage.  Man-yi will seriously set back efforts to recover from the previous typhoons.

Typhoon Man-yi Intensifies to Equivalent of Cat. 5 Hurricane

Typhoon Man-yi intensified to the equivalent of a Category 5 hurricane on the Saffir-Simpson Scale on Saturday.  At 10:00 a.m. EST on Saturday the center of Typhoon Man-yi was located at latitude 14.2°N and longitude 124.0°E which put the center about 80 miles (130 km) east of Labo, Philippines.  Man-yi was moving toward the northwest at 15 m.p.h. (24 km/h).  The maximum sustained wind speed was 160 m.p.h. (260 km/h) and there were wind gusts to 195 m.p.h. (315 km/h).  The minimum surface pressure was 921 mb.

Typhoon Man-yi intensified to the equivalent of a Category 5 hurricane as it approached southeastern Luzon on Saturday.  The southwestern part of Man-yi’s eyewall passed over Catanduanes Island.

Typhoon Man-yi was very impressive on satellite images.  A circular eye with a diameter of 20 miles (32 km) was at the center of Man-yi’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 Man-yi’s circulation.  Storms near the center of Man-yi generated strong upper level divergence that pumped large amounts of mass away from the typhoon in all directions. The removal of large quantities of mass caused the surface pressure to decrease rapidly.

The size of the circulation around Typhoon Man-yi increased when Man-yi intensified.  Winds to typhoon force extended out 45 miles (75 km) from the center of Man-yi’s circulation.  Winds to tropical storm force extended out 150 miles (240 km) from the center of Typhoon Man-yi.

The Hurricane Intensity Index (HII) for Typhoon Man-yi was 35.0.  The Hurricane Size Index (HSI) was 17.6 and the Hurricane Wind Intensity Size Index (HWISI) was 52.6.  Typhoon Man-yi was similar in intensity to Hurricane Michael when Michael hit Northwest Florida in 2018.  Man-yi was bigger than Michael was.

Typhoon Man-yi will move through an environment favorable for intensification during the next few hours.  Man-yi 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 the Western North Pacific Ocean.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Typhoon Man-yi could continue to intensify during the next few hours.  However, the fact that the southwestern part of Man-yi’s eyewall passed over Catanduanes Island could halt its intensification.

Typhoon Man-yi will move around the southern side of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Man-yi toward the northwest during the next 24 hours.  On its anticipated track, Typhoon Man-yi will reach southeastern Luzon in 12 hours.  The center of Man-yi’s circulation could make landfall northeast of Baler.

Typhoon Man-yi is already bringing destructive winds to Catanduanes Island.  Typhoon Man-yi will also bring very strong winds and heavy rain to Luzon.  Heavy rain will cause flash floods and mudslides.  Man-yi could also cause a storm surge of up to 13 feet (4 meters) along the coast of Luzon. Luzon has already been hit by a series of in recent weeks.  Typhoon Man-yi is capable of causing regional catastrophic damage.  Man-yi will seriously set back efforts to recover from the previous typhoons.

Elsewhere over the Western North Pacific Ocean, Tropical Depression Usagi was still dropping heavy rain on parts of Taiwan. At 4:00 a.m. EST on Saturday the center of Tropical Depression Usagi was located at latitude 22.3°N and longitude 120.7°E which put the center about 35 miles (55 km) south of Kaohsiung, Taiwan.  Usagi was moving toward the southeast at 4 m.p.h. (6 km/h).  The maximum sustained wind speed was 30 m.p.h. (50 km/h) and there were wind gusts to 40 m.p.h. (65 km/h).  The minimum surface pressure was 1006 mb.  Continued heavy rain is likely to cause flash floods in Taiwan.

Typhoon Man-Yi Strengthens to Equivalent of a Major Hurricane

Typhoon Man-yi strengthened to the equivalent of a major hurricane as it moved toward the Philippines on Friday.  At 4:00 p.m. EST on Friday the center of Typhoon Man-yi was located at latitude 12.3°N and longitude 127.2°E which put the center about 490 miles (790 km) east-southeast of Manila, Philippines.  Man-yi was moving toward the west-northwest at 15 m.p.h. (24 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 952 mb.

Typhoon Man-yi intensified to the equivalent of a major hurricane on Friday.  A circular eye with a diameter of 25 miles (40 km) was at the center of Man-yi’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 Man-yi’s circulation.  Storms near the center of Man-yi generated strong upper level divergence that pumped mass away from the typhoon in all directions.  The removal of large quantities of mass caused the surface pressure to decrease rapidly.

The Hurricane Intensity Index (HII) for Typhoon Man-yi was 23.6.  The Hurricane Size Index (HSI) was 10.3 and the Hurricane Wind Intensity Size Index (HWISI) was 33.9.  Typhoon Man-yi was similar in size and intensity to Hurricane Dennis when Dennis hit Northwest Florida in 2005.

Typhoon Man-yi will move through an environment favorable for intensification during the next 24 hours.  Man-yi 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 the Western North Pacific Ocean.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Typhoon Man-yi is likely to continue to intensify during the next 24 hours.

Typhoon Man-yi will move around the southern side of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Man-yi toward the west-northwest during the next 24 hours.  On its anticipated track, Typhoon Man-yi will reach southeastern Luzon in less than 18 hours.

Typhoon Man-yi will bring very strong winds and heavy rain to Luzon.  Heavy rain will cause flash floods and mudslides.  Man-yi could also cause a storm surge of up to 13 feet (4 meters) along the coast of Luzon.  Luzon has already been hit by a series of in recent weeks.  Typhoon Man-yi is capable of causing regional major damage.  Man-yi will seriously set back efforts to recover from the previous typhoons.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Usagi was bringing wind and rain to Taiwan.  At 4:00 p.m. EST on Friday the center of Tropical Storm Usagi was located at latitude 22.5°N and longitude 120.3°E which put the center about 25 miles (40 km) southwest of Kaohsiung, Taiwan.  Usagi was moving toward the north-northeast at 10 m.p.h. (16 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.  Heavy rain is likely to cause flash floods in Taiwan.

Man-yi Strengthens to a Typhoon East of the Philippines

Former Tropical Storm Man-yi strengthened to a typhoon east of the Philippines on Thursday.  At 10:00 p.m. EST on Thursday the center of Typhoon Man-yi was located at latitude 10.7°N and longitude 131.3°E which put the center about 795 miles (1280 km) east-southeast of Manila, Philippines.  Man-yi was moving toward the west at 18 m.p.h. (30 km/h).  The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 100 m.p.h. (160 km/h).  The minimum surface pressure was 976 mb.

Former Tropical Storm Man-yi strengthened to a typhoon over the Western North Pacific Ocean east of the Philippines on Thursday.  The inner end of a rainband wrapped around the center of Man-yi’s circulation.  A circular eye with a diameter of 23 miles (37 km) formed at the center of Typhoon Man-yi.  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 Man-yi’s circulation.  Storms near the center of Man-yi generated upper level divergence that pumped mass away from the typhoon.  The removal of mass caused the surface pressure to decrease.

Typhoon Man-yi will move through an environment favorable for intensification during the next 24 hours. Man-yi 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 the Western North Pacific Ocean.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Typhoon Man-yi will intensify during the next 24 hours.  Man-yi could intensify rapidly.  Typhoon Man-yi is likely to strengthen to the equivalent of a major hurricane.

Typhoon Man-yi will move around the southern side of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Man-yi toward the west-northwest during the next 24 hours.  On its anticipated track, Typhoon Man-yi will move toward Luzon.  Man-yi could approach Luzon in 36 hours.

Elsewhere over the Western North Pacific Ocean, Typhoon Usagi moved toward Taiwan.  At 10:00 p.m. EST on Thursday the center of Typhoon Usagi was located at latitude 20.2°N and longitude 120.2°E which put the center about 145 miles (235 km) south of Kaohsiung, Taiwan.  Usagi was moving toward the north-northwest at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 100 m.p.h. (160 km/h).  The minimum surface pressure was 977 mb.

Typhoon Usagi Hits Northern Luzon

Typhoon Usagi hit northern Luzon on Wednesday night.  At 10:00 p.m. EST on Wednesday the center of Typhoon Usagi was located at latitude 17.6°N and longitude 122.7°E which put the center about 1205 miles (195 km) southeast of Aparri, Philippines.  Usagi was moving toward the northwest at 14 m.p.h. (22 km/h). The maximum sustained wind speed was 150 m.p.h. (240 km/h) and there were wind gusts to 185 m.p.h. (295 km/h).  The minimum surface pressure was 915 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) was 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 inner end of a rainband wrapped around the existing eye and eyewall at the center of Usagi’s circulation during Wednesday evening and concentric eyewalls could be forming.

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 85 miles (135 km) from the center of Typhoon Usagi.

The Hurricane Intensity Index (HII) for Typhoon Usagi was 31.6.  The Hurricane Size Index (HSI) was 9.4 and the Hurricane Wind Intensity Size Index (HWISI) was 41.0 . Typhoon Usagi was similar in size to Hurricane Ida when Ida hit Louisiana in 2021.  Usagi was not as big as Ida was.

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 northwest during the next 24 hours.  On its anticipated track, the center of Typhoon Usagi will move across northeast Luzon during the next few 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, former Tropical Storm Toraji weakened to a tropical depression south of Hong Kong, and Tropical Storm Man-yi was moved north of Yap.

At 10:00 p.m. EST on Wednesday the center of Tropical Depression Toraji was located at latitude 21.0°N and longitude 113.9°E which put the center about 90 miles (145 km) south of Hong Kong.  Toraji was moving toward the west-southwest 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 1005 mb.

The circulation around Typhoon Toraji was small.  Winds to typhoon force extended out 30 miles (50 km) from the center of Toraji’s circulation.  Winds to tropical storm force extended out 90 miles (145 km) from the center of Typhoon Toraji.

The Hurricane Intensity Index (HII) for Typhoon Toraji was 13.9.  The Hurricane Size Index (HSI) was 7.7. and the Hurricane Wind Intensity Size Index (HWISI) was 21.6.  Typhoon Toraji was similar in size and intensity to Hurricane Isaias when Isaias hit North Carolina in 2020.

Typhoon Toraji will move through an environment favorable for intensification during the next few hours. Toraji 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 Toraji will continue to intensify during the next few hours.

Typhoon Toraji will move around the southern side of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Toraji toward the west-northwest during the next 24 hours.  On its anticipated track, the center Typhoon Toraji will reach Luzon in a few hours.

A low pressure system over the Western North Pacific Ocean east of the Philippines strengthened rapidly on Saturday and the Japan Meteorological Agency designated the system as Tropical Storm Toraji.  The circulation around Tropical Storm Toraji organized quickly on Saturday.  Bands of showers and thunderstorms were revolving around the center of Toraji’s circulation.  Storms near the center of Toraji 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 Toraji was small.  Winds to tropical storm force extended out 65 miles (105 km) from the center of Toraji’s circulation.

Tropical Storm Toraji will move through an environment favorable for intensification during the next 24 hours.  Toraji 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.  Tropical Storm Toraji will intensify during the next 24 hours.  Toraji could intensify rapidly at times.  Tropical Storm Toraji is likely to strengthen to a typhoon on Sunday.

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

Tropical Storm Toraji is likely to be a typhoon when it reaches northern Luzon.  Toraji will bring strong winds and locally heavy rain to northern Luzon.  Heavy rain is likely to cause flash floods and mudslides.  Northern Luzon is trying to recover from two recent typhoons.  Typhoon Toraji is likely to seriously disrupt those recovery activities.

Elsewhere over the Western North Pacific Ocean, Typhoon Yinxing passed south of Hong Kong and Tropical Storm Man-yi formed east of the Marianas.

At 4:00 p.m. EST on Saturday the center of Typhoon Yinxing was located at latitude 19.1°N and longitude 113.1°E which put the center about 220 miles (360 km) south-southwest of Hong Kong.  Yinxing was moving toward the west-northwest at 4 m.p.h. (6 km/h).  The maximum sustained wind speed was 120 m.p.h. (195 km/h) and there were wind gusts to 150 m.p.h. (240 km/h).  The minimum surface pressure was 960 mb.

At 4:00 p.m. EST on Saturday the center of Tropical Storm Man-yi was located at latitude 16.1°N and longitude 156.1°E which put the center about 720 miles (1160 km) east of Saipan.  Man-yi was moving toward the northwest at 25 m.p.h. (40 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 999 mb.

Powerful Typhoon Yinxing Brings Wind and Rain to Northern Luzon

Power Typhoon Yinxing was bringing wind and rain to northern Luzon on Thursday.  At 7:00 a.m. EST on Thursday the center of Typhoon Yinxing was located at latitude 18.5°N and longitude 122.0°E which put the center about 35 miles (55 km) northeast of Aparri, Philippines.  Yinxing was moving toward the west at 8 m.p.h. (13 km/h).  The maximum sustained wind speed was 145 m.p.h. (230 km/h) and there were wind gusts to 175 m.p.h. (280 km/h).  The minimum surface pressure was 937 mb.

The eye of powerful Typhoon Yinxing was just north of the coast of northern Luzon on Thursday morning.  The eye had a diameter of  23 miles (37 km).  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 of Yinxing generated strong upper level divergence that pumped large amounts of mass away from the typhoon.  The removal of large amounts of mass in the upper level slightly exceed the inflow of mass in the lower levels of the atmosphere, which caused the surface pressure to decrease.

The circulation around Typhoon Yinxing was large.  Winds to typhoon force extended out 50 miles (80 km) from the center of Yinxing’s circulation.  Winds to tropical storm force extended out 200 miles (325 km) from the center of Typhoon Yinxing.

The Hurricane Intensity Index (HII) for Typhoon Yinxing was 29.9.  The Hurricane Size Index (HSI) was 19.7 and the Hurricane Wind Intensity Size Index (HWISI) was 49.6.  Typhoon Yinxing was similar in size and intensity to Hurricane Laura when Laura hit southwest 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.  Even though Typhoon Yinxing will move through an environment favorable for intensification, much of the southern half of Yingxing’s circulation, including the southern side of the eyewall, will move across northern Luzon.  Since almost half of Yinxing’s circulation will move over land Typhoon Yinxing will 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 near the north coast of Luzon during the next 24 hours.

Typhoon Yinxing will continue to bring strong, gusty winds and heavy rain to northern Luzon during the next 24 hours.  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 severe damage.
