Typhoon Muifa Brings Wind and Rain to Eastern China

Typhoon Muifa brought wind and rain to eastern China on Wednesday afternoon. At 5:00 p.m. EDT on Wednesday the center of Typhoon Muifa was located at latitude 31.8°N and longitude 121.5°E which put it about 20 miles (30 km) east of Shanghai, China. Muifa was moving toward the north-northwest at 16 m.p.h. (26 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 978 mb.

Typhoon Muifa brought strong winds and heavy rain to parts of eastern China near Shanghai on Wednesday afternoon. The center of Typhoon Muifa made an initial landfall on the east coast of China southeast of Shanghai near Ningbo. Although Muifa was weakening at the time it made landfall, the northern part of the eyewall was still intact. The strongest winds and heaviest rain were occurring in that part of the eyewall. Bands of showers and thunderstorms were also revolving around the center of Typhoon Muifa. Winds to typhoon force extended out 30 miles (50 km) from the center of Muifa’s circulation. Winds to tropical storm force extended out 100 miles (160 km) from the center of circulation.

Typhoon Muifa will move around the western side of a high pressure system over the Western North Pacific Ocean. The high pressure system will steer Muifa toward the north during the next 24 hours. On its anticipated track Typhoon Muifa will move along the east coast of China. Muifa will continue to bring strong winds and locally heavy rain as it moves along the coast. Heavy rain could fall over coastal areas of Jiangsu and Shandong. Heavy could cause flash floods in some locations.

Elsewhere over the Western North Pacific Ocean, Typhoon Merbok was moving quickly toward the far western Aleutian Islands and Tropical Storm Nanmadol was strengthening southwest of Iwo To. At 5:00 p.m. EDT on Wednesday the center of Typhoon Merbok was located at latitude 35.5N and longitude 163.2°E which put it about 1355 miles (2185 km) south-southwest of Kiska, Alaska. Merbok was moving toward the north at 23 m.p.h. (37 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 981 mb.

At 5:00 p.m. EDT on Wednesday the center of Tropical Strm Nanmadol was located at latitude 23.2°N and longitude 139.4°E which put it about 150 miles (240 km) southwest of Iwo To. Nanmadol was moving toward the west-northwest at 6 m.p.h. (10 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 984 mb.

Typhoon Muifa Moves Toward Eastern China

Typhoon Muifa moved toward eastern China on Tuesday morning. At 11:00 a.m. EDT on Tuesday the center of Typhoon Muifa was located at latitude 27.2°N and longitude 123.7°E which put it about 280 miles (450 km) south-southeast of Shanghai, China. Muifa was moving toward the north-northwest at 8 m.p.h. (13 km/h). The maximum sustained wind speed was 105 m.p.h. (165 km/h) and there were wind gusts to 125 m.p.h. (200 km/h). The minimum surface pressure was 964 mb.

The circulation around Typhoon Mauifa exhibited good organization on Tuesday morning. A circular eye was present at the center of Muifa. 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 Typhoon Muifa. Storms near the core generated upper level divergence that pumped mass away from the typhoon.

The wind field around Typhoon Muifa way very symmetrical. Winds to typhoon force extended out 40 miles (65 km) from the center of Muifa. Winds to tropical storm force extended out 150 miles (240 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Muifa was 17.8. The Hurricane Size Index (HSI) was 17.1 and the Hurricane Wind Intensity Size Index (HWISI) was 34.9. Typhoon Muifa was capable of causing regional serious damage.

Typhoon Muifa will move through an environment that will be unfavorable for intensification during the next 24 hours. Muifa will move over water where the Sea Surface Temperatures are near 27˚C. An upper level trough over China will produce southwesterly winds that will blow toward the top of Muifa’s circulation. Those winds will cause the vertical wind shear to increase during the next 24 hours. The increase in wind shear and cooler water will cause Typhoon Muifa to weaken gradually.

Typhoon Muifa will move around the western part of a high pressure system over the Western North Pacific Ocean. The high pressure system will steer Muifa toward the north-northwest during the next 24 hours. On its anticipated track Typhoon Muifa will make landfall on the east coast of China south of Shanghai in 18 hours. The center of Muifa could make landfall near Ningbo. Typhoon Muifa will bring strong winds and locally heavy rain to the region around Shanghai. Heavy rain could cause flash floods in some locations in eastern China.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Merbok strengthened north-northwest of Wake Island and Tropical Depression 16W also strengthened southwest of Iwo To. At 11:00 a.m. EDT on Tuesday the center of Tropical Storm Merbok was located at latitude 26.2N and longitude 162.7°E which put it about 500 miles (805 km) north-northwest of Wake Island. Merbok was moving toward the north-northwest at 10 m.p.h. (16 km/h). The maximum sustained wind speed was 70 m.p.h. (110 km/h) and there were wind gusts to 85 m.p.h. (135 km/h). The minimum surface pressure was 984 mb.

At 11:00 a.m. EDT on Tuesday the center of Tropical Depression 16W was located at latitude 22.6N and longitude 139.6°E which put it about 190 miles (310 km) southwest of Iwo To. The tropical depression was moving toward the northeast at 6 m.p.h. (10 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 1000 mb.

Tropical Storm In-Fa Makes Landfall near Shanghai

Tropical Storm In-Fa made landfall on the east coast of China near Shanghai on Sunday. At 5:00 p.m. EDT on Sunday the center of Tropical Storm In-Fa was located at latitude 30.6°N and longitude 121.4°E which put it about 50 miles (80 km) south of Shanghai, China. In-Fa was moving toward the northwest at 6 m.p.h. (10 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 987 mb.

Tropical Storm In-Fa weakened slowly as it approached the east coast of China. The circulation around In-Fa pulled drier air from Asia into the western side of the former typhoon. The drier air caused thunderstorms in the western half of Tropical Storm In-Fa to weaken. The strongest thunderstorms were occurring in bands on the eastern side of In-Fa. Bands in the western half of the tropical storm consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 165 miles (270 km) on the eastern side of In-Fa. The strongest winds were occurring over the waters of the East China Sea. Winds to tropical storm force extended out 80 miles on the western side of the circulation.

Tropical Storm In-Fa will move slowly toward the northwest, which will take it farther inland over eastern China. The circulation around In-Fa will weaken gradually as the tropical storm moves farther inland. Tropical Storm In-Fa will bring gusty winds and locally heavy rain to the region around Shanghai and Ningbo. Heavy rain could cause flash floods in some locations.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Nepartak swirled southwest of Japan. At 5:00 p.m. EDT on Sunday the center of Tropical Storm Nepartak was located at latitude 33.4°N and longitude 149.7°E which put it about 630 miles (1015 km) east-southeast of Tokyo, Japan. Nepartak was moving toward the north 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.

Typhoon In-Fa Brings Wind and Rain to Ryukyu Islands

Typhoon In-Fa brought gusty winds and locally heavy rain to the Ryukyu Islands on Friday. At 11:00 a.m. EDT on Friday the center of Typhoon In-Fa was located at latitude 25.1°N and longitude 124.9°E which put it about 30 miles (50 km) northwest of Hirara, Japan. In-Fa was moving toward the northwest at 5 m.p.h. (8 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 969 mb.

The slow movement of Typhoon In-Fa during the past several days and its large size caused In-Fa to mix cooler water to the surface in a large area. The cooler water meant that In-Fa extracted less energy from the ocean and thunderstorms weakened in parts of the circulation around the typhoon. There was still a large circular eye with a diameter of of 65 miles (105 km) at the center of Typhoon In-Fa. The eye was surrounded by a broken ring of thunderstorms and the strongest winds were occurring in the broken ring of storms. Bands of showers and thunderstorms continued to revolve around the center of In-Fa. Storms near the center of circulation generated upper level divergence that pumped mass away from the typhoon.

The circulation around Typhoon In-Fa was large. Winds to typhoon force extended out 80 miles (130 km) from the center of In-Fa. Winds to tropical storm force extended out 270 miles (435 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon In-Fa was 11.5. The Hurricane Size Index (HSI) was 31.7 and the Hurricane Wind Intensity Size Index (HWISI) was 43.2.

Typhoon In-Fa will move through an environment somewhat favorable for intensification during the next 24 hours. Once the center of In-Fa moves away from the cooler water mixed to the surface, the typhoon will move over water where the Sea Surface Temperatures are near 28°C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. The large size of Typhoon In-Fa will mean that intensification could be slow to occur. Typhoon In-Fa could strengthen during the next 24 hours.

Typhoon In-Fa will move around the southwestern part of a high pressure system over the Western North Pacific Ocean during the next 36 hours. The high will steer In-Fa toward the northwest. On its anticipated track Typhoon In-Fa will move slowly away from the Ryukyu Islands. Since the circulation around In-Fa is so large, the typhoon will continue to produce gusty winds and locally heavy rain for another 24 hours. The center of Typhoon In-Fa could approach the east coast of China south of Ningbo in 48 hours.

Typhoon Mitag Passing Just East of China

Typhoon Mitag was passing just to the east of China on Monday night.  At 11:00 p.m. EDT on Monday the center of Typhoon Mitag was located at latitude 27.7°N and longitude 122.2°E which put it about 250 miles (400 km) south-southeast of Shanghai, China.  Mitag was moving toward the north-northeast at 14 m.p.h. (22 km/h).  The maximum sustained wind speed was 85 m.p.h. (135 km/h) and there were wind gusts to 105 m.p.h. (165 km/h).  The minimum surface pressure was 970 mb.

Typhoon Mitag began to weaken later on Monday.  An upper level  trough over eastern Asia was producing southerly winds which were blowing toward the top of the circulation.  Those winds were causing moderate vertical wind shear.  The circulation around Mitag was drawing drier air from Asia into the southern and western parts of the typhoon.  There was still an eye at the center of Typhoon Mitag.  However the ring of strong thunderstorms around the eye weakened.  The stronger bands of showers and thunderstorms were in the northern half of the circulation.  Bands in the southern half of the circulation consisted primarily of showers and lower clouds.  Winds to typhoon force extended out 60 miles (95 km) from the center of circulation.  Winds to tropical storm force extended out 215 miles (345 km) from the center.

Typhoon Mitag will likely to continue to weaken during the next several days.  The upper level trough will continue to cause moderate vertical wind shear.  The circulation around Mitag will also continue to draw drier air from Asia into the typhoon.  Typhoon Mitag will continue to weaken slowly and it could weaken to a tropical storm  within 24 hours.

The upper level trough will steer Typhoon Mitag toward the north-northeast during the next 12 to 24 hours.  Mitag will turn more toward the northeast in a day or so.  On its anticipated track Typhoon Mitag will pass to the east of Ningbo and Shanghai.  Mitag could approach South Korea in about 36 hours.  It will likely be a tropical storm by that time, but Mitag could drop locally heavy rain over South Korea.

Tropical Storm Jongdari Makes Landfall South of Shanghai, Shanshan Forms Northeast of Guam

Tropical Storm Jongdari made landfall south of Shanghai on Thursday, while Tropical Storm Shanshan formed northeast of Guam.  At 11:00 p.m. EDT on Thursday the center of Tropical Storm Jongdari was located at latitude 30.7°N and longitude 121.4°E which put it about 40 miles (65 km) south of Shanghai, China.  Jongdari was moving toward the west at 19 m.p.h. (30 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 994 mb.

The center of Tropical Storm Jongdari made landfall on the east coast of China near Zhoushan and Ningbo on Thursday.  Jongdari retained a distinct low level center of circulation while it made landfall.  The tropical storm brought gusty winds to the coast of Zhejiang and Shanghai Shi provinces.  Tropical Storm Jongdari dropped locally heavy rain over parts of those provinces and some flooding could occur.  The center of Jongdari will move quickly toward Hangzhou and the risk of flooding will continue as the tropical storm moves inland and weakens.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Shanshan formed northeast of Guam.  At 11:00 p.m. EDT on Thursday the center of Tropical Storm Shanshan was located at latitude 17.9°N and longitude 150.1°E which put it about 460 miles (740 km) northeast of Guam.  Shanshan was moving toward the west-southwest at 7 m.p.h. (11 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. (65 km/h).  The minimum surface pressure was 998 mb.

A distinct low level center of circulation formed in a cluster of thunderstorms east of the Northern Marianas on Thursday and the Japan Meteorological Agency designated the system as Tropical Storm Shanshan.  The circulation of Shanshan was still organizing.  Several bands of showers and thunderstorms developed southwest of the center of circulation.  Bands northeast of the center consisted mostly of showers and lower clouds.  Storms near the center of circulation started to generate upper level divergence.

Tropical Storm Shanshan will move through an environment favorable for intensification.  Shanshan will move over water where the Sea Surface Temperature is near 28°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Tropical Storm Shanshan will intensify and it could strengthen into a typhoon during the weekend.

Tropical Storm Shashan will move around the western end of a subtropical high pressure system.  The high will steer Shanshan in a general northwesterly direction during the next 12 to 24 hours.  It will turn more toward the north during the weekend.  On its anticipated track Tropical Storm Shanshan will move near the Northern Marianas during the next 24 to 36 hours.
