Typhoon Gaemi Strengthens to Equivalent of a Major Hurricane

Typhoon Gaemi strengthened to the equivalent of a major hurricane east of Taiwan on Tuesday.  At 5:00 p.m. EDT on Tuesday the center of Typhoon Gaemi was located at latitude 23.1°N and longitude 123.2°E which put the center about 200 miles (325 km) southeast of Taipei, Taiwan.  Gaemi was moving toward the northwest at 15 m.p.h. (24 km/h).  The maximum sustained wind speed was 140 m.p.h. (225 km/h) and there were wind gusts to 165 m.p.h. (265 km/h).  The minimum surface pressure was 948 mb.

Typhoon Gaemi rapidly intensified to the equivalent of a Category 4 hurricane on the Saffir-Simpson Scale east of Taiwan on Tuesday.  A small circular eye with a diameter of 6 miles (10 km) formed at the center of Gaemi’s circulation.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storm.  Bands of showers and thunderstorms were revolving around the core of Typhoon Gaemi.  Storms near the core generated strong upper level divergence that pumped mass away from the typhoon.  The removal of large amounts of mass caused the surface pressure to decrease rapidly.

The circulation around Typhoon Gaemi was large.  Winds to typhoon force extended out 100 miles (160 km) from the center of Gaemi’s circulation.  Winds to tropical storm force extended out 345 miles (555 km) from the center of Typhoon Gaemi.

The Hurricane Intensity Index (HII) for Typhoon Gaemi was 28.3.  The Hurricane Size Index (HSI) was 31.0 and the Hurricane Wind Intensity Size Index (HWISI) was 59.3.  Typhoon Gaemi was similar in size to Hurricane Wilma when Wilma hit South Florida in 2005.  Gaemi is stronger than Wilma was when it hit South Florida.

Typhoon Gaemi will move through an environment favorable for intensification during the next 12 hours.  Gaemi will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the 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 Gaemi could continue to intensify during the next 12 hours.

Typhoon Gaemi will move around the western part of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Typhoon Gaemi toward the northwest during the next 24 hours.  On its anticipated track, Typhoon Gaemi will approach the coast of northeastern Taiwan in 12 hours.

Typhoon Gaemi will bring very strong winds and torrential rain to Taiwan.  Gaemi will be capable of causing extensive severe damage.  Heavy rain is likely to cause widespread flash floods.  Typhoon Gaemi will also be capable of causing a storm surge of up to 13 feet (4 meters) along the east coast of Taiwan.

Typhoon Gaemi will also bring strong winds and heavy rain to the southern Ryukyu Islands.  The strongest part Gaemi’s circulation will pass southwest of the Ryukyu Islands, but the typhoon is likely to some wind damage.  Heavy rain could cause flash floods in some locations.

Typhoon Gaemi will move toward the east coast of China after is crosses northern Taiwan.  Gaemi could approach the coast of China in less than 36 hours.  Typhoon Gaemi will weaken when it moves over Taiwan, but Gaemi could still be a typhoon when it reaches China.

Elsewhere, former Tropical Storm Prapiroon weakened to a tropical depression over northern Vietnam.  At 11:00 a.m. EDT on Tuesday the center of Tropical Depression Prapiroon was located at latitude 22.0°N and longitude 107.0°E which put the center about 25 miles (40 km) northeast of Lang Son, Vietnam.  Prapiroon was moving toward the north-northwest at 5 m.p.h. (8 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 994 mb.

Gaemi Intensifies to Typhoon Southeast of Taiwan

Former Tropical Storm Gaemi intensified to a typhoon over the Western North Pacific Ocean southeast of Taiwan on Monday.  At 5:00 p.m. EDT on Monday the center of Typhoo Gaemi was located at latitude 18.8°N and longitude 124.7°E which put the center about 405 miles (655 km) southeast of Hualien, Taiwan.  Gaemi was moving toward the west at 6 m.p.h. (10 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 977 mb.

Former Tropical Storm Gaemi exhibited more organization on Monday as it strengthened to a typhoon.  The inner end of a rainband wrapped around the center of Gaemi’s circulation.  An eye appeared to be forming at the center of Typhoon Gaemi.  A ring of showers and thunderstorms surrounded the developing eye.  The ring was thickest in the southeastern side of the eye and thinnest in the northwestern side.  Other bands of thunderstorms were occurring southern and eastern parts of Gaemi’s circulation.  Bands in the northern and western parts of Typhoon Gaemi consisted primarily of showers and lower clouds.

Winds to typhoon force extended out 45 miles (75 km) from the center of Typhoon Gaemi.  Winds to tropical storm force extended out 155 miles (250 km) from the center of Gaemi’s circulation.

Typhoon 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 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 Gaemi will continue to intensify during the next 24 hours.

Typhoon Gaemi will move around the western part of a high pressure system over the Western North Pacific Ocean.  The high pressure system will steer Typhoon Gaemi toward the northwest during the next 24 hours.  On its anticipated track, Typhoon Gaemi will approach the east coast of Taiwan in 36 hours.

Typhoon Gaemi will bring strong winds and heavy rain to Taiwan during the middle of the week.  Heavy rain is likely to cause flash floods.

Elsewhere, Tropical Storm Prapiroon brought wind and rain to northern Vietnam.  At 5:00 p.m. EDT on Monday the center of Tropical Storm Prapiroon was located at latitude 21.2°N and longitude 107.9°E which put the center about 40 miles (65 km) east of Cam Pha, Vietnam.  Prapiroon was moving toward the northwest at 8 m.p.h. (13 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 985 mb.

(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.

(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.

Former Tropical Storm Talim strengthened steadily during the weekend and Talim reached typhoon intensity on Sunday. The inner end of a rainband wrapped around the center of Typhoon Talim’s circulation. An eye was evident on conventional and microwave satellite images. The eye was surrounded by a broken ring of thunderstorms and the strongest winds were occurring in the ring of storms. Bands of showers and thunderstorms revolved around the core of Typhoon Talim. Storms near the core generated upper level divergence that pumped mass away from the typhoon. Winds to typhoon force extended out 20 miles (30 km) in the northern side of Talim’s circulation. Winds to tropical storm force extended out 140 miles (220 km) from the center of Talim.

Typhoon Talim will move through an environment favorable for intensification during the next 24 hours. Talim will move over water where the Sea Surface Temperatures are near 30˚C. It will move under the southern side of an upper level ridge that extends from the Western North Pacific Ocean to China. The ridge will produce easterly winds that will blow toward the top of Talim’s circulation. Those winds will cause some vertical wind shear but the wind shear will not be enough to prevent intensification. Typhoon Talim will intensify during the next 24 hours.

Typhoon Talim will move around the southwestern part of a subtropical high pressure system over the Western North Pacific Ocean. The high pressure system will steer Talim toward the west-northwest during the next 24 hours.
