Leave a reply

Tropical Storm Toraji rapidly developed over the Western North Pacific Ocean east of the Philippines on Saturday.  At 4:00 p.m. EST on Saturday the center of Tropical Storm Toraji was located at latitude 15.1°N and longitude 127.7°E which put the center about 495 miles (795 km) east of Manila, Philippines.  Toraji was moving toward the west at 20 m.p.h. (32 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.

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.

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.

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
