Tropical Storm Gaemi Brings Wind and Rain to Eastern China

Tropical Storm Gaemi brought wind and rain to parts of eastern China on Thursday.  At 11:00 a.m. EDT on Thursday the center of Tropical Storm Gaemi was located at latitude 25.9°N and longitude 119.1°E which put the center about 25 miles (40 km) west of Fuzhou, China.  Gaemi was moving toward the 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 973 mb.

Former Typhoon Gaemi weakened to a tropical storm on Thursday before it made landfall on the east coast of China.  The center of Gaemi’s circulation made landfall southeast of Fuzhou near Fuqing.  Showers and thunderstorms in bands in the eastern and southern parts of Tropical Storm Gaemi were dropping heavy rain.  The bands in the northern and western parts of Gaemi’s circulation consisted primarily of showers and lower clouds.

The circulation around Tropical Storm Gaemi was large.  Winds to tropical storm force extended out 220 miles (350 km) from the center of Gaemi’s circulation.  The strongest winds were occurring in bands that were still over water in the eastern and southern parts of Tropical Storm Gaemi.

Tropical Storm Gaemi will move toward the northwest during the next 24 hours.  Gaemi will weaken as it moves farther inland over eastern China.  Tropical Storm Gaemi will drop heavy rain over parts of Fujian, Jiangxi and Zhejiang.  Heavy rain is likely to cause floods in some locations.

Tropical Storm Prapiroon Brings Wind and Rain to Hainan

Tropical Storm Prapiroon brought wind and rain to Hainan on Sunday.  At 5:00 p.m. EDT on Sunday the center of Tropical Storm Prapiroon was located at latitude 19.1°N and longitude 109.9°E which put the center about 65 miles (105 km) south-southwest of Haikou, China.  Prapiroon was moving toward the northwest at 13 m.p.h. (21 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 992 mb.

Tropical Storm Prapiroon intensified on Sunday before the center moved over Hainan.  Microwave satellite images indicated that an eye was in the process of forming at the center of Prapiroon’s circulation as the tropical storm made landfall in Hainan.  The formative 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 center of Tropical Storm Prapiroon.

Winds to tropical storm force extended out 70 miles (110 km) from the center of Tropical Storm Prapiroon.

The center of Tropical Storm Prapiroon made landfall on the south coast of Hainan near Lingshui.  The core of Prapiroon’s circulation moved across the center of Hainan.  Storms near the center of Tropical Storm Prapiroon brought heavy rain and strong winds to much of Hainan.  Bands in the northern part of Hainan’s circulation were also bringing gusty winds and heavy rain to parts of southern China.

Tropical Storm Prapiroon will move around the southern side of a high pressure system over southern China.  The high pressure system will steer Prapiroon toward the northwest during the next 24 hours.  On its anticipated track Tropical Storm Prapiroon will move over the Gulf of Tonkin on Monday.  The center of Prapiroon’s circulation could approach the southern coast of China in 24 hours.

Tropical Storm Prapiroon will continue to cause strong winds and locally heavy rain in Hainan during the next few hours.  Heavy rain could cause flash floods in some locations.  Prapiroon will also bring gusty winds and heavy rain to parts of southern China and northeastern Vietnam.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Gaemi strengthened east of Luzon.  At 5:00 p.m. EDT on Sunday the center of Tropical Storm Gaemi was located at latitude 17.2°N and longitude 125.7°E which put the center about 525 miles (845 km) south of Ishigakijima, Japan.  Gaemi was moving toward the north-northwest at 3 m.p.h. (5 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 992 mb.

Tropical Storm Prapiroon Forms Over South China Sea

Tropical Storm Prapiroon formed over the South China Sea on Saturday night.  At 11:00 p.m. EDT on Saturday the center of Tropical Storm Prapiroon was located at latitude 16.3°N and longitude 111.2°E which put the center about 260 miles (460 km) south-southeast of Haikou, China.  Prapiroon was moving toward the west at 5 m.p.h. (8 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.

Former Tropical Depression 04W strengthened on Saturday night and the Japan Meteorological Agency designated the system as Tropical Storm Prapiroon.  The circulation around Tropical Storm Prapiroon was exhibiting a little more organization.  There were not a lot of thunderstorms near the center of Prapiroon’s circulation.  Thunderstorms were occurring in bands revolving around the center of Tropical Storm Prapiroon.

Although the circulation around Tropical Storm Prapiroon was large, the area of stronger winds was relatively small.  Winds to tropical storm force extended out 60 miles (95 km) from the center of Prapiroon’s circulation.

Tropical Storm Prapiroon will move through an environment somewhat favorable for intensification during the next 24 hours.  Prapiroon will move over water where the Sea Surface Temperatures are near 30°C.   It will move under the southeastern part of an upper level ridge over China.  The upper level ridge will produce northeasterly winds that will blow toward the top of Prapiroon’s circulation.  Those winds will cause moderate vertical wind shear.  The wind shear will inhibit intensification but the shear may not be strong enough to prevent some strengthening.  Tropical Storm Prapiroon could intensify a little during the next 24 hours.

Tropical Storm Prapiroon will move around the southern part of a high pressure system over eastern China.  The high pressure system will steer Prapiroon toward the northeast during the next 24 hours.  On its anticipated track Tropical Storm Prapiroon will move toward Hainan.

Tropical Storm Prapiroon will bring gusty winds and heavy rain to Hainan during the next 24 hours.  Heavy rain could cause flash floods in some locations.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Gaemi strengthened gradually east of the Philippines.  At 11:00 p.m. EDT on Saturday the center of Tropical Storm Gaemi was located at latitude 17.0°N and longitude 125.5°E which put the center about 485 miles (780 km) south of Ishigakijima, Japan.  Gaemi was moving toward the west-northwest at 9 m.p.h. (15 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 996 mb.

Tropical Storm Gaemi Forms East of the Philippines

Tropical Storm Gaemi formed over the Western North Pacific Ocean east of the Philippines early on Saturday.   At 5:00 a.m. EDT on Saturday the center of Tropical Storm Gaemi was located at latitude 16.1°N and longitude 128.2°E which put the center about 520 miles (840 km) south-southeast of Ishigakijima, Japan.  Gaemi was moving toward the northwest at 14 m.p.h. (22 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 1002 mb.

A low pressure system over the Western North Pacific Ocean east of the Philippines strengthened early on Saturday and the Japan Meteorological Agency designated the system as Tropical Storm Gaemi.  The circulation around Tropical Storm Gaemi was starting to exhibit more organization.  More thunderstorms were forming near the center of Gaemi’s circulation.  Thunderstorms were also developing in bands revolving around the center of Tropical Storm Gaemi.  Storms near the center of Gaemi started to generate upper level divergence that pumped mass away from the tropical storm.

Tropical Storm Gaemi will move through an environment favorable for intensification during the next 24 hours.  Gaemi will move over water where the Sea Surface Temperatures are near 30°C.   It will move under the western 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 Gaemi’s circulation.  Those winds will cause some vertical wind shear, but the wind shear will not be enough to prevent intensification.  Tropical Storm Gaemi is likely to intensify gradually during the next 24 hours.  Gaemi could strengthen to a typhoon by early next week.

Tropical Storm Gaemi will move around the western part of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Gaemi toward the northwest during the next 24 hours.  On its anticipated track, Tropical Storm Gaemi will move toward the southern Ryukyu Islands.  Gaemi could be a typhoon when it approaches the southern Ryukyu Islands early next week.

Elsewhere over the Western North Pacific Ocean, Tropical Depression 04W formed over the South China Sea.  At 5:00 a.m. EDT on Saturday the center of Tropical Depression 04W was located at latitude 16.1°N and longitude 113.8°E which put the center about 360 miles (580 km) southeast of Haikou, China.   The tropical depression was moving toward the northwest at 7 m.p.h. (11 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 999 mb.

Tropical Storm Gaemi Brings Wind and Rain to Okinawa

Tropical Storm Gaemi brought wind and rain to Okinawa late on Friday.  At 11:00 p.m. EDT on Friday the center of Tropical Storm Gaemi was located at latitude 26.7°N and longitude 127.9°E which put it near Okinawa.  Gaemi was moving toward the east-northeast at 19 m.p.h (30 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 990 mb.

Tropical Storm Gaemi became better organized after it moved across southern Taiwan early on Friday.  The center of circulation was more evident on microwave satellite images.  A primary band of showers and thunderstorms formed in the eastern side of circulation.  Other showers and thunderstorms were located farther to the northeast of the center of Tropical Storm Gaemi.  An upper level trough west of Gaemi was producing string southwesterly winds which were blowing toward the top of the tropical storm.  Those winds were causing moderate vertical wind shear and they were likely the reason why most of the heavier rain was occurring northeast of the center of circulation.

The upper level trough was also steering Tropical Storm Gaemi quickly toward the east-northeast.  On its anticipated track Gaemi will move over the middle Ryukyu Islands including Amami-O-Shima during the next 12 hours.  Tropical Storm Gaemi will continue to produce gusty winds and locally heavy rain.  Most of the rain will fall before the center of circulation reaches a location.  Gaemi is likely to make a transition to an extratropical cyclone when it moves south of the larger islands of Japan during the weekend.

Tropical Storm Gaemi Forms Near Southwest Taiwan

Tropical Storm Gaemi formed near Kaohsiung on the southwest coast of Taiwan late on Thursday.  At 8:00 p.m. EDT on Thursday the center of Tropical Storm Gaemi was located at latitude 22.8°N and longitude 120.2°E which put it near Kaohsiung, Taiwan.  Gaemi was moving toward the northeast at 5 m.p.h. (8 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 992 mb.

A distinct low level center of circulation developed in an area of showers and thunderstorms southwest of Taiwan on Thursday and the Japan Meteorological Agency designated the system as Tropical Storm Gaemi.  Thunderstorms developed near the core of the circulation.  Several short bands of showers and thunderstorms were revolving around the core.  Mountains in eastern Taiwan may have deflected the flow in the lower levels and contributed to the organization of a center of circulation.  Storms around the center were generating some upper level divergence which was pumping mass away to the east of the tropical storm.

Tropical Storm Gaemi is likely to weaken during the next few hours while the center of circulation moves across southern Taiwan.  Mountains in eastern Taiwan could disrupt the lower portions of the circulation when it moves over them.  If the circulation still exists when it moves east of Taiwan in a few hours, then Tropical Storm Gaemi will move into a more favorable environment for intensification.  Gaemi will move over water where the Sea Surface Temperature is near 29°C.  An upper level trough over eastern Asia is producing southwesterly winds which are blowing toward the top of the circulation.  Those winds will cause some vertical wind shear, but the shear will probably not be strong enough to tear the circulation apart.  Gaemi could remain a tropical storm for another 24 to 36 hours.  When Tropical Storm Gaemi moves farther north in a day or two, it will move over colder water and into an area with stronger vertical wind shear.  Gaemi will likely make a transition to an extratropical cyclone at that time.

The upper level trough is forecast to steer Tropical Storm Gaemi toward the northeast.  Gaemi will move across southern Taiwan during the next few hours.  It will cause gusty winds, but the greater risks will be heavy rain and flash floods.  On its anticipated track Tropical Storm Gaemi will move near the southern Ryukyu Islands of Japan.  It could pass near Ishigaki Jima and Miyako Jima in the next 12 to 18 hours.  Gaemi could be near Okinawa later on Friday.
