Tropical Storm Mitag Brings Wind and Rain to South Korea

Tropical Storm Mitag brought wind and rain to South Korea on Wednesday.  At 5:00 p.m. EDT on Wednesday the center of Tropical Storm Mitag was located at latitude 36.1°N and longitude 128.5°E which put it about 20 miles (30 km) north-northeast of Taegu, South Korea.  Mitag was moving toward the northeast at 21 m.p.h. (34 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h).  The minimum surface pressure was 993 mb.

Tropical Storm Mitag moved quickly across South Korea on Wednesday.  An upper level trough over eastern Asia was producing strong southwesterly winds which steered Mitag quickly toward the northeast.  Those winds were also causing strong vertical wind shear, which was blowing the upper part of Tropical Storm Mitag northeast of the lower level circulation.  The vertical wind shear and the tilting of the circulation toward the northeast were contributing to the transition of Mitag to an extratropical cyclone.  The strongest winds were occurring in the eastern portion of the tropical storm over the Korea Strait and Sea of Japan.  Winds to tropical storm force extended out 155 miles (250 km) on that side of Tropical Storm Mitag.

Tropical Storm Mitag was dropping heavy rain over parts of South Korea.  The rain could cause flash floods in some locations.  Rain will taper off when Tropical Storm Mitag moves away from South Korea on Thursday.  Mitag will start to move more toward the east when it makes the transition to an extratropical cyclone.  On its anticipated track the extratropical storm will move quickly across the Sea of Japan and it could reach northern Honshu in about 24 hours.  It could drop locally heavy rain on parts of northern Honshu and cause flash floods in some locations.

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.

Typhoon Mitag Nears Northeast Taiwan

Typhoon Mitag moved nearer to northeastern Taiwan on Sunday night.  At 11:00 p.m. EDT on Sunday the center of Typhoon Mitag was located near latitude 22.3°N and longitude 122.7°E which put it about 180 miles (290 km) south-southeast of Taipei, Taiwan.  Mitag was moving toward the northwest at 14 m.p.h. (22 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 976 mb.

Former Tropical Storm Mitag strengthened into a typhoon on Sunday.  A circular eye appeared at the center of Typhoon Mitag on satellite images.  The eye was surrounded by a ring of thunderstorms.  There were some breaks in the ring of storms, but the strongest winds were occurring in the ring.  Bands of showers and thunderstorms were revolving around the core of Typhoon Mitag.  Storms near the core were generating upper level divergence which was pumping mass away in all directions.  Winds to typhoon force extended out 50 miles (80 km) from the center of circulation.  Winds to tropical storm force extended out about 185 miles (295 km) from the center.

Typhoon Mitag will move through an environment favorable for intensification during the next 12 to 24 hours.  Mitag 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 not too strong and there will not be a lot of vertical wind shear.  Typhoon Mitag could strengthen on Monday if the center of circulation does not pass over northeastern Taiwan.  If the center of Mitag does move over Taiwan, then the typhoon will weaken,

Typhoon Mitag will move around the western end of a ridge of high pressure over the Western North Pacific Ocean.  The ridge will steer Mitag toward the north-northwest.  On its anticipated track the center of Typhoon Mitag will be near northeastern Taiwan within 12 hours.  Mitag could drop heavy rain over parts of Taiwan and flash floods are possible.  Rainbands in the eastern side of the typhoon will bring gusty winds and heavy rain to the southern Ryukyu Islands.  Typhoon Mitag could approach the east coast of China near Taizhou in about 36 hours.

Tropical Storm Mitag Forms Southeast of Ryukyu Islands

Tropical Storm Mitag formed southeast of the Ryukyu Islands on Friday.  At 11:00 p.m. EDT on Friday the center of Tropical Storm Mitag was located at latitude 16.4°N and longitude 131.5°E which put it about 730 miles (1180 km) southeast of Ishigaki, Japan.  Mitag was movign toward the west-northwest at 27 m.p.h. (44 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h).  The minimum surface pressure was 994 mb.

More thunderstorms developed near the center of a low pressure system southeast of the Ryukyu Islands on Friday and the Japan Meteorological Agency designated the system as Tropical Storm Mitag.  The distribution of thunderstorms around Tropical Storm Mitag was asymmetrical.  A few thunderstorms developed near the center of circulation, but most of the thunderstorms were forming in bands in the southern half of the circulation.  Bands in the northern half of Mitag consisted primarily of showers and lower clouds.  Tropical Storm Mitag was moving around the southwestern portion of an upper level ridge over the Western North Pacific Ocean.  The ridge was producing northeasterly winds which were blowing toward the top of Mitag.  Those winds were causing moderate vertical wind shear and they were contributing to the asymmetrical distribution of thunderstorms.

Tropical Storm Mitag will move through an environment somewhat favorable for intensification during the next two days.  Mitag will move over water where the Sea Surface Temperature is near 29°C.  Mitag will move around the western end of the upper level ridge where the winds are weaker.  The wind shear is likely to decrease and Tropical Storm Mitag is forecast to strengthen into a typhoon during the weekend.

The ridge over the Western North Pacific Ocean will steer Tropical Storm Mitag toward the northwest during the next 24 to 36 hours.  Mitag will move more toward the north when it moves around the west end of the ridge in about 48 hours.  On its anticipated track Tropcial Storm Mitag could reach the southern Ryukyu Islands in about 48 hours.  Mitag could be a typhoon at that time.
