Tropical Storm Nesat Drops Rain on Hainan

Tropical Storm Nesat dropped rain on Hainan on Tuesday night. At 11:00 p.m. EDT on Tuesday the center of Tropical Storm Nesat was located at latitude 17.0°N and longitude 110.5°E which put it about 100 miles (160 km) south-southeast of Lingshui China. Nesat was moving toward the west at 12 m.p.h. (19 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 988 mb.

Former Typhoon Nesat weakened to a tropical storm on Tuesday as it moved over the South China Sea southeast of Hainan. An upper level ridge over China produced easterly winds that blew toward the top of Nesat’s circulation. Those winds caused moderate vertical wind shear and the wind shear caused an asymmetrical distribution of thunderstorms around Tropical Storm Nesat. Most of the thunderstorms were occurring in the northwestern part of Nesat. Those thunderstorms dropped heavy rain over Hainan and parts of southern China. Winds to tropical storm force extended out 200 miles (320 km) from the center of Nesat.

Tropical Storm Nesat will move through an environment unfavorable for intensification during the next 48 hours. Nesat will move over water where the Sea Surface Temperatures are near 29˚C. It will continue to move under the southern part of the over China. The ridge will produce easterly winds that will cause moderate vertical wind shear and the wind shear will inhibit intensification. A surface high pressure system over southern China will produce northeasterly winds that will transport drier air into the northern and western parts of Tropical Storm Nesat. The vertical wind shear and the drier air will cause Tropical Storm Nesat to continue to weaken during the next 48 hours.

The surface high pressure system over southern China will steer Tropical Storm Nesat toward the west during the next 48 hours. On its anticipated track, the center of Tropical Storm Nesat will pass south of Hainan during the next 24 hours. Nesat could approach the coast of Vietnam in 36 hours. Bands on the northern side of Tropical Storm Nesat will drop locally heavy rain on parts of Hainan, southern China and northern Vietnam. Heavy rain could cause flash floods in some locations.

Typhoon Nesat Passes South of Hong Kong

Typhoon Nesat passed south of Hong Kong as it moved across the South China Sea on Monday night. At 11:00 p.m. EDT on Monday the center of Typhoon Nesat was located at latitude 18.0°N and longitude 113.3°E which put it about 285 miles (460 km) south of Hong Kong. Nesat was moving toward the west-southwest at 12 m.p.h. (19 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 971 mb.

Typhoon Nesat started to weaken on Monday night as it passed south of Hong Kong. A circular eye was still present at the center of Nesat’s circulation. However a break occurred in the southeastern part of the ring of thunderstorms surrounded the eye of Typhoon Nesat. The strongest winds were occurring in the broken ring of thunderstorms. Bands of showers and thunderstorms were occurring in the western half of Nesat. Bands in the eastern side of the circulation consisted primarily of showers and lower clouds. Storms near the center of Nesat generated upper level divergence that pumped mass away to the west of the typhoon.

The circulation around Typhoon Nesat interacted with a large surface high pressure system over southern China to produce a large area of tropical storm force winds in the northern part of Nesat’s circulation. Winds to tropical storm force extended out 400 miles (640 km) in the northern side of Typhoon Nesat. Winds to tropical storm force extended out 120 miles (195 km) in the southern side of Nesat. Winds to typhoon force extended out 40 miles (65 km) from the center of circulation.

Typhoon Nesat will move through an environment unfavorable for intensification during the next 48 hours. Nesat will move over water where the Sea Surface Temperatures are near 29˚C. It will move under the southern part of an upper level ridge that extends over the Western North Pacific Ocean to southern China. The ridge will produce easterly winds that will cause moderate vertical wind shear and the wind shear will inhibit intensification. The surface high pressure system over southern China will produce northeasterly winds that will transport drier air into the northern and western parts of Typhoon Nesat. The vertical wind shear and the drier air will cause Typhoon Nesat to weaken during the next 48 hours.

The surface high pressure system over southern China will steer Typhoon Nesat toward the west during the next 48 hours. On its anticipated track, Typhoon Nesat will pass south of Hainan in 36 hours. Nesat is likely to weaken to a tropical storm by the time it passes south of Hainan. Nesat could bring gusty winds and locally heavy rain to Hainan on Tuesday night and Wednesday.

Nesat Intensifies to a Typhoon Northwest of Luzon

Former Tropical Storm Nesat intensified to a typhoon over the South China Sea northwest of Luzon on Sunday morning. At 5:00 a.m. EDT on Sunday the center of Typhoon Nesat was located at latitude 19.6°N and longitude 119.5°E which put it about 125 miles (200 km) northwest of Laoag, Philippines. Nesat was moving toward the west-northwest at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 80 m.p.h. (130km/h) and there were wind gusts to 100 m.p.h. (160 km/h). The minimum surface pressure was 978 mb.

Former Tropical Storm Nesat rapidly intensified to a typhoon over the South China Sea on Sunday morning. A circular eye with a diameter of 30 miles (50 km) formed at the center of Typhoon Nesat. The 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 core of Nesat’s circulation. The strongest rainbands were in the western and northern parts of the circulation. Storms near the core of Nesat generated upper level divergence that pumped mass away from the typhoon. Winds to typhoon force extended out 40 miles (65 km) from the center of Nesat’s circulation. Storms to tropical storm force extended out 150 miles (240 km) from the center of circulation.

Typhoon Nesat will move through an environment favorable for intensification during the next 24 hours. Nesat will move over water where the Sea Surface Temperatures are near 29˚C. It will move under the southern part of an upper level ridge that extends over the Western North Pacific Ocean to eastern China. The ridge will produce easterly winds that will cause some vertical wind shear. The wind shear will inhibit intensification, but Typhoon Nesat will strengthen during the next 24 hours. Nesat could continue to intensify rapidly during the next few hours.

Typhoon Nesat will move around the southern side of a surface high pressure system over the Western North Pacific Ocean and eastern China. The high pressure system will steer Nesat toward the west during the next several days. On its anticipated track Typhoon Nesat could be south of Hong Kong within 48 hours.

Tropical Storm Nesat Develops near Northern Luzon

Tropical Storm Nesat developed over the Western North Pacific Ocean near northern Luzon on Saturday morning. At 5:00 a.m. EDT on Saturday the center of Tropical Storm Nesat was located at latitude 18.6°N and longitude 123.5°E which put it about 160 miles (260 km) east of Claveria, Philippines. Nesat was moving toward the 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 1000 mb.

The circulation around a low pressure system over the Western North Pacific Ocean near northern Luzon strengthened on Saturday morning and the Japan Meteorological Agency designated the system as Tropical Storm Nesat. The distribution of thunderstorms in Tropical Storm Nesat was asymmetrical. Many of the thunderstorms were occurring in bands in the western half of Nesat’s circulation. Bands in the eastern side of Tropical Storm Nesat consisted primarily of showers and lower clouds. Storms near the center of Nesat generated upper level divergence that pumped mass away to the west of the tropical storm. Winds to tropical storm force extended out 125 miles (200 km) in the northern side of Nesat’s circulation. The winds in the southern half of the circulation were blowing at less than tropical storm force.

Tropical Storm Nesat will move through an environment favorable for intensification during the next 36 hours. Nesat will move over water where the Sea Surface Temperatures are near 29˚C. It will move under the southern part of an upper level ridge over the Western North Pacific Ocean. The ridge will produce easterly winds that will cause some vertical wind shear. The wind shear will inhibit intensification, but Tropical Storm Nesat is likely to strengthen during the next 36 hours. Nesat could intensify to a typhoon by the end of the weekend.

Tropical Storm Nesat will move around the southern side of a surface high pressure system over the Western North Pacific Ocean. The high pressure system will steer Nesat toward the west during the next 36 hours. On its anticipated track, Tropical Storm Nesat will pass near northern Luzon during the next 24 hours. Nesat will bring gusty winds and locally heavy rain to northern Luzon. Heavy rain could cause flash floods in some locations. Tropical Storm Nesat will move over the South China Sea on Sunday.
