Typhoon Yinxing Intensifies to Equivalent of a Major Hurricane

Leave a reply

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.
