Tropical Storm Chan-hom Moves Toward Japan

Leave a reply

Tropical Storm Chan-hom was moving toward Japan on Monday morning.  At 11:00 a.m. EDT on Monday the center of Tropical Storm Chan-hom was located at latitude 35.7°N and longitude 147.1°E which put the center about 460 miles (745 km) east of Tokyo, Japan.  Chan-hom was moving toward the northwest at 12 m.p.h. (19 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 981 mb.

The surface center of Tropical Storm Chan-hom is under the eastern part of an upper level low.  The upper level low is producing southeasterly winds that are blowing toward the top of Chan-hom’s circulation.  Those winds are causing moderate vertical wind shear.  The circulation around Tropical Storm Chan-hom is also puling drier air into the southern and eastern parts of Chan-hom’s circulation.

The combination of the moderate vertical wind shear and the drier air is causing the distribution of thunderstorms in Tropical Storm Chan-hom to be asymmetrical.  Thunderstorms are occurring in bands in the western half of Chan-hom’s circulation.  Bands in the eastern part of Tropical Storm Chan-hom consist primarily of showers and lower clouds.  Storm near the enter of Chan-hom generated upper level divergence that pumped mass away from the tropical storm.  The removal of mass caused the surface pressure to decrease.

The distribution of wind speeds in Tropical Storm Chan-hom was also asymmetrical.  Winds to tropical storm force extended out 145 miles (235 km) in the northern half of Chan-hom’s circulation.  Winds to tropical storm force only extended out 70 miles (110 km) in the southern half of Tropical Storm Chan-hom.

Tropical Storm Chan-hom will move through an environment that will be somewhat favorable for intensification during the next 24 hours.  Chan-hom will move over water where the Sea Surface Temperatures are near 26°C.  However, the upper level low just to the west of the low level center of Chan-hom’s circulation will continue to cause moderate vertical wind shear.  Tropical Storm Chan-hom could intensify a little in spite of the moderate vertical wind shear.

The upper level low just to the west of the surface center of Tropical Storm Chan-hom will steer Chan-hom toward the west during the next 24 hours.  On its anticipated track, the center of Tropical Storm Chan-hom will reach the coast of Honshu northeast of Tokyo in about 24 hours.

Tropical Storm Chan-hom will bring strong winds and locally heavy rain to parts of central Honshu.  Heavy rain is likely to cause floods in some locations.

Elsewhere, Tropical Storm Dolphin continued to drop heavy rain over parts of eastern China and former Tropical Storm Peilou weakened to a tropical depression.

At 8:00 a.m. EDT on Monday the center of Tropical Storm Dolphin was located at latitude 29.0°N and longitude 117.9°E which put the center about 60 miles (95 km) southeast of Jingdezhen, China.  Dolphin was moving toward the north-northwest at 10 m.p.h. (16 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.

At 11:00 a.m. EDT on Monday the center of Tropical Depression Peilou was located at latitude 22.1°N and longitude 153.6°E which put the center about 195 miles (315 km) south-southwest of Minami Tori Shima.  Peilou was moving toward the northeast at 20 m.p.h. (32 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 993 mb.

Typhoon Dolphin hit the coast of eastern China near Wenzhou early on Sunday.  At 5:00 a.m. EDT on Sunday the center of Typhoon Dolphin was located at latitude 28.2°N and longitude 121.4°E which put the center about 50 miles (80 km) east of Wenzhou, China.  Dolphin was moving toward the west-northwest 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 954 mb.

Typhoon Dolphin made landfall on the east coast of China near Wenzhou early on Sunday.  Dolphin was a large typhoon.  Winds to typhoon force extended out 35 miles (55 km) from the enter of Dolphin’s circulation.  Winds to tropical storm force extended out 295 miles (475 km) from the center of Typhoon Dolphin.

The Hurricane Intensity Index (HII) for Typhoon Dolphin is 12.7.  The Hurricane Size Index (HSI) is 16.7 and the Hurricane Wind Intensity Size Index (HWISI) is 29.4.  Typhoon Dolphin is similar in intensity to Hurricane Isaac when Isaac hit southeast Louisiana in 2012.  Typhoon Dolphin is much larger than Isaac was.

Typhoon Dolphin will move around the southern side of a high pressure system that is over the Western North Pacific Ocean.  The high pressure system will steer Dolphin toward the west-northwest during the next 24 hours.  On its anticipated track, the center of Typhoon Dolphin will continue to move farther inland over eastern China during the next 24 hours.

Typhoon Dolphin will bring strong winds and heavy rain to parts of eastern China.  Dolphin will bring strong winds and heavy rain to Zhejiang, Anhui, and Jiangsu.  Heavy rain is likely to cause floods in some locations.  Typhoon Dolphin could also produce a storm surge of up to 10 feet (3 meters) along parts of the east coast of China.

Even though Typhoon Dolphin will weaken as it moves farther inland, Dolphin could also drop heavy rain over parts of Henan, Shandong, Hebei, and Shanxi as it moves farther inland.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Chan-hom was still churning east of Japan and Tropical Storm Peilou formed south of Iwo To.

At 5:00 a.m. EDT on Sunday the center of Tropical Storm Chan-hom was located at latitude 32.4°N and longitude 150.5°E which put the center about 650 miles (1050 km) east-southeast of Tokyo, Japan.  Chan-hom was moving toward the west-northwest at 4 m.p.h. (6 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 984 mb.

At 5:00 a.m. EDT on Sunday the center of Tropical Storm Peilou was located at latitude 21.0°N and longitude 143.6°E which put the center about 265 miles (425 km) south-southeast of Iwo To.  Peilou was moving toward the east-southeast at 15 m.p.h. (24 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 Dolphin Approaches East Coast of China

Leave a reply

Typhoon Dolphin was approaching the east coast of China on Saturday night.  At 11:00 p.m. EDT on Saturday the center of Typhoon Dolphin was located at latitude 27.9°N and longitude 122.7°E which put the center about 130 miles (210 km) east of Wenzhou, China.  Dolphin was moving toward the northwest at 11 m.p.h. (17 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 959 mb.

Typhoon Dolphin weakened gradually on Saturday as it approached the east coast of China.  Dolphin appeared to pull drier air from China into the western side of its circulation.  The drier air caused thunderstorms in bands in the western side of Typhoon Dolphin to weaken.  A small circular eye was still present at the center of Dolphin’s circulation.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were still occurring in the eastern side of Dolphin’s circulation.  Storms near the core of Dolphin generated upper level divergence that pumped mass away from the typhoon.  The removal of mass in the upper levels was less than the convergence of mass in the lower levels of the atmosphere.  So, the surface pressure increased slowly on Saturday.

The area of stronger winds in Typhoon Dolphin decreased in size on Saturday.  Winds to typhoon force extended out 35 miles (55 km) from the enter of Dolphin’s circulation.  Winds to tropical storm force extended out 310 miles (500 km) from the center of Typhoon Dolphin.

The Hurricane Intensity Index (HII) for Typhoon Dolphin is 11.5.  The Hurricane Size Index (HSI) is 17.0 and the Hurricane Wind Intensity Size Index (HWISI) is 28.5.  Typhoon Dolphin is similar in intensity to Hurricane Isaac when Isaac hit southeast Louisiana in 2012.  Typhoon Dolphin is much larger than Isaac was.

Typhoon Dolphin will move through an environment that will be unfavorable for intensification during the next 12 hours.  Dolphin will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the middle of an upper level ridge that is over the Western North Pacific Ocean.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  However, the circulation around Typhoon Dolphin will continue to pull drier air over China into its circulation.  Typhoon Dolphin is likely to continue to weaken gradually during the next 12 hours.

Typhoon Dolphin will move around the southern side of a high pressure system that is over the Western North Pacific Ocean.  The high pressure system will steer Dolphin toward the west-northwest during the next 24 hours.  On its anticipated track, the center of Typhoon Dolphin will hit the east coast of China just to the north of Wenzhou in less about 12 hours.

Typhoon Dolphin will bring strong winds and heavy rain to parts of eastern China.  Dolphin will bring strong winds and heavy rain to Zhejiang, Anhui, and Jiangsu.  Heavy rain is likely to cause floods in some locations.  Typhoon Dolphin could also produce a storm surge of up to 10 feet (3 meters) along parts of the east coast of China.

Typhoon Dolphin could also drop heavy rain over parts of Henan, Shandong, Hebei, and Shanxi after it moves inland.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Chan-hom continued to spin east of Japan.  At 11:00 p.m. EDT on Friday the center of Tropical Storm Chan-hom was located at latitude 32.2°N and longitude 150.8°E which put the center about 670 miles (1080 km) east of Tokyo, Japan.  Chan-hom was moving toward the west-southwest at 8 m.p.h. (13 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.

Typhoon Dolphin Moves Toward Eastern China

Typhoon Dolphin moved away from Okinawa and toward eastern China on Friday.  At 5:00 p.m. EDT on Friday the center of Typhoon Dolphin was located at latitude 26.6°N and longitude 126.2°E which put the center about 350 miles (565 km) east-southeast of Wenzhou, China. Dolphin was moving toward the west at 11 m.p.h. (17 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 948 mb.

Typhoon Dolphin maintained its intensity as it moved away from Okinawa on Friday.  A small circular eye was visible at the center of Dolphin’s circulation.  A band of thunderstorms surrounded the eye and the strongest winds were occurring in that band of storms.  Bands of showers and thunderstorms were revolving around the core of Dolphin’s circulation.  Storms near the core of Dolphin generated upper level divergence that pumped mass away from the typhoon.  The removal of mass in the upper levels was nearly equal to the convergence of mass in the lower levels of the atmosphere.  So, the surface pressure did not change much on Friday.

Typhoon Dolphin was a large typhoon.  Winds to typhoon force extended out 145 miles (235 km) in the northern half of Dolphin’s circulation.  Winds to typhoon force extended out 20 miles (30 km) in the southern half of Typhoon Dolphin.  Winds to tropical storm force extended out 305 miles (490 km) from the center of Dolphin’s circulation.

The Hurricane Intensity Index (HII) for Typhoon Dolphin is 17.8.  The Hurricane Size Index (HSI) is 32.3 and the Hurricane Wind Intensity Size Index (HWISI) is 50.1.  Typhoon Dolphin is similar in size and intensity to Hurricane Frances when Frances hit South Florida in 2004.

Typhoon Dolphin will move through an environment that will become less favorable for intensification during the next 24 hours.  Dolphin will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the middle of an upper level ridge that is over the Western North Pacific Ocean.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  However, the circulation around Typhoon Dolphin could pull drier air over China into its circulation.  Typhoon Dolphin is likely to start to weaken gradually as it moved closer to eastern China.

Typhoon Dolphin will move around the southern side of a high pressure system that is over the Western North Pacific Ocean.  The high pressure system will steer Dolphin toward the west during the next 24 hours.  On its anticipated track, the center of Typhoon Dolphin could hit the east coast of China in less than 48 hours.

The large circulation around Typhoon Dolphin will continue to produce strong winds and locally heavy rain to the Ryukyu Islands on Saturday.

Typhoon Dolphin will bring strong winds and heavy rain to parts of eastern China by the end of the weekend.  Dolphin will bring strong winds and heavy rain to Zhejiang, Anhui, and Jiangsu.  Heavy rain is likely to cause floods in some locations.  Typhoon Dolphin could also produce a storm surge of up to 10 feet (3 meters) along parts of the east coast of China.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Chan-hom weakened east of Japan.  At 5:00 p.m. EDT on Friday the center of Tropical Storm Chan-hom was located at latitude 32.3°N and longitude 157.3°E which put the center about 1100 miles (1775 km) east of Tokyo, Japan.  Chan-hom was moving toward the northwest at 18 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 990 mb.

Typhoon Dolphin hit Okinawa on Thursday evening.  At 11:00 p.m. EDT on Thursday the center of Typhoon Dolphin was located at latitude 27.2°N and longitude 128.3°E which put the center about 25 miles (40 km) north-northeast of Okinawa.  Dolphin was moving toward the west at 17 m.p.h. (28 km/h).  The maximum sustained wind speed was 100 m.p.h. (160 km/h) and there were wind gusts to 120 m.p.h. (195 km/h).  The minimum surface pressure was 955 mb.

Typhoon Dolphin started to intensify on Thursday evening as it approached Okinawa.  A small circular eye was visible at the center of Dolphin’s circulation on satellite and radar images.   Bands of showers and thunderstorms were revolving around the core of Dolphin’s circulation.    Storms near the core of Dolphin generated upper level divergence that pumped mass away from the typhoon.  The removal of mass in the upper levels was greater than the convergence of mass in the lower levels of the atmosphere.  So, the surface pressure decreased a little on Thursday.

The eye of Typhoon Dolphin was passing just to the north of Okinawa.  The southern part of the eyewall of Dolphin was passing over northern Okinawa.

A weather station at Naha Airport (ROAH) in Okinawa reported a sustained wind speed of 46 m.p.h. (74 km/h) and a wind gust of 61 m.p.h. (98 km/h).

Typhoon Dolphin was a large typhoon.  Winds to typhoon force extended out 140 miles (220 km) in the northern half of Dolphin’s circulation.  Winds to typhoon force extended out 70 miles (110 km) in the southern half of Typhoon Dolphin.  Winds to tropical storm force extended out 310 miles (500 km) from the center of Dolphin’s circulation.

The Hurricane Intensity Index (HII) for Typhoon Dolphin is 16.5.  The Hurricane Size Index (HSI) is 38.3 and the Hurricane Wind Intensity Size Index (HWISI) is 54.8

Typhoon Dolphin will move through an environment that will be favorable for intensification during the next 24 hours.  Dolphin will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the middle of an upper level ridge that is over the Western North Pacific Ocean.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Typhoon Dolphin could intensify on Friday as long as Okinawa does not disrupt the inner core of its circulation..

Typhoon Dolphin will move around the southern side of a high pressure system that is over the Western North Pacific Ocean.  The high pressure system will steer Dolphin toward the west during the next 24 hours.  On its anticipated track, the center of Typhoon Dolphin will move west of the Ryukyu Islands on Friday.  Dolphin could hit the east coast of China in less than 48 hours.

Typhoon Dolphin will continue to bring strong winds and heavy rain to the Ryukyu Islands on Friday.  The strongest winds and heaviest rain will occur in Okinawa.  Heavy rain will cause flash floods in some locations.  Typhoon Dolphin could also cause a storm surge of up to 10 feet (3 meters) along the coast of some of the islands.

Even the center of Typhoon Dolphin will pass north of Taiwan, bands in the southern part of Dolphin’s circulation will drop heavy rain on northern Taiwan.

Typhoon Dolphin will also bring strong winds and heavy rain to eastern China.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Chan-hom formed southeast of Japan.  At 11:00 p.m. EDT on Thursday the center of Tropical Storm Chan-hom was located at latitude 29.6°N and longitude 160.3°E which put the center about 1300 miles (2095 km) east-southeast of Tokyo, Japan.  Chan-hom was moving toward the northwest at 17 m.p.h. (28 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.

Typhoon Noul Hits Near Hong Kong

The center of Typhoon Noul hit the coast of China just to the northeast of Hong Kong on Saturday.  At 5:00 p.m. EDT on Saturday the center of Typhoon Noul was located at latitude 22.7°N and longitude 114.8°E which put the center about 60 miles (95 km) east of Hong Kong.  Noul was moving toward the northwest at 14 m.p.h. (22 km/h).  The maximum sustained wind speed was 100 m.p.h. (160 km/h) and there were wind gusts to 120 m.p.h. (195 km/h).  The minimum surface pressure was 967 mb.

Typhoon Noul continued to intensify until it made landfall on the coast of China just to the northeast of Hong Kong.  Typhoon Noul was the equivalent of a Category 2 hurricane on the Saffir-Simpson Scale at the time it made landfall.

A circular eye with a diameter of 20 miles (32 km) was at the center of Typhoon Noul when Noul made landfall.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Noul’s circulation.

The distribution of wind speeds around Typhoon Noul was fairly symmetrical.  Winds to typhoon force extended out 40 miles (65 km) from the center of Noul’s circulation.  Winds to tropical storm force extended out 140 miles (220 km) from the center of Typhoon Noul.

The Hurricane Intensity Index (HII) for Typhoon Noul was 16.5.  The Hurricane Size Index (HSI) was 14.6 and the Hurricane Wind Intensity Size Index (HWISI) was 31.1.  Typhoon Noul was capable of causing regional serious damage.

Typhoon Noul will move around the western end of a high pressure system that is over the Western North Pacific Ocean.  The high pressure system will steer Noul toward the north-northwest during the next 24 hours.  On its anticipated track, the center of Typhoon Noul will move inland over eastern Guangdong and Jiangxi.

Noul Intensifies to a Typhoon

Former Tropical Storm Noul intensified to a typhoon over the Western North Pacific Ocean east-southeast of Hong Kong on Friday.  At 11:00 p.m. EDT on Friday the center of Typhoon Noul was located at latitude 21.1°N and longitude 117.8°E which put the center about 285 miles (455 km) east-southeast of Hong Kong.  Noul was moving toward the northwest at 14 m.p.h. (22 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 980 mb.

Former Tropical Storm Noul intensified to a typhoon on Friday.  The inner end of a rainband wrapped around the center of Noul’s circulation.  A small circular eye formed at the center of Typhoon Noul.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Typhoon Noul.  Storms near the core of Noul generated upper level divergence that pumped mass away from the typhoon.  The removal of mass caused the surface pressure to decrease.

The distribution of wind speed around Typhoon Noul was fairly symmetrical.  Winds to typhoon force extended out 35 miles (55 km) from the center of Noul’s circulation.  Winds to tropical storm force extended out 125 miles (200 km) from the center of Typhoon Noul.

Typhoon Noul will move through an environment favorable for intensification during the next 12 hours.  Noul will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the middle of an upper level ridge that is centered over eastern China.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear. Typhoon Noul will intensify during the next 12 hours.

Typhoon Noul will move around the southwestern part of a high pressure system that is over the Western North Pacific Ocean.  The high pressure system will steer Noul toward the northwest during the next 24 hours.  On its anticipated track, the center of Typhoon Noul will make landfall on the coast of southeastern China northeast of Hong Kong in 15 hours.

Typhoon Noul will bring strong winds and locally heavy rain to eastern Guangdong, southern Fujian, and Jiangxi.  Heavy rain is likely to cause flash floods in some locations.  Typhoon Noul could cause a storm surge of up to 12 feet (3.6 meters) along parts of the coast of southeastern China.

Tropical Storm Noul Forms East of Northern Luzon

Tropical Storm Noul formed over the Western North Pacific Ocean east of northern Luzon on Thursday afternoon.  At 5:00 p.m. EDT on Thursday the center of Tropical Storm Noul was located at latitude 18.6°N and longitude 124.4°E which put the center about 180 miles (290 km) east of Aparri, Philippines.  Noul was moving toward the west-northwest at 17 m.p.h. (28 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.

A low pressure system over the Western North Pacific Ocean east of northern Luzon strengthened on Thursday afternoon and the Japan Meteorological Agency designated the system as Tropical Storm Noul.

More thunderstorms were forming near the center of Tropical Storm Noul.  Thunderstorms were also occurring in bands in the western half of Noul’s circulation.  Bands in the eastern side of Tropical Storm Noul consisted primarily of showers and lower clouds.  Storm near the center of Noul began to generate upper level divergence that pumped mass away to the west of the tropical storm.  The removal of mass caused the surface pressure to decrease.

The distribution of wind speeds in Tropical Storm Noul was also asymmetrical.  Winds to tropical storm force extended out 175 miles (280 km) in the southern side of Noul’s circulation.  Winds to tropical storm force extended out 80 miles (130 km) in the northern side of Tropical Storm Noul.

Tropical Storm Noul will move through an environment favorable for intensification during the next 24 hours.  Noul will move over water where the Sea Surface Temperatures are near 30°C.  It will move under the southern part of an upper level ridge that is centered east of China.  The upper level ridge will produce northeasterly winds that will blow toward the top of Noul’s circulation.  Those winds will cause some vertical wind shear, but the wind shear will not be enough to prevent intensification.  Tropical Storm Noul will intensify during the next 24 hours.  Noul is likely to strengthen to a typhoon by the weekend.

Tropical Storm Noul will move around the southern part of a high pressure system that is over the Western North Pacific Ocean.  The high pressure system will steer Noul toward the west-northwest during the next 24 hours.  On its anticipated track, the center of Tropical Storm Noul will pass south of Taiwan on Friday.  Noul is likely to hit southeastern China during the weekend.

Tropical Storm Noul will bring gusty winds and heavy rain to northern Luzon.  Heavy rain could cause flash floods.  Noul will also bring strong winds and heavy rain to Taiwan.  Heavy rain is likely to cause flash floods.  Tropical Storm Noul is likely to be a typhoon when it hits southeastern China.

Typhoon Bavi Hits Eastern China

Typhoon Bavi hit the east coast of China near Wenzhou on Saturday.  At 11:00 a.m. EDT on Saturday the center of Typhoon Bavi was located at latitude 28.1°N and longitude 121.2°E which put the center about 25 miles (40 km) east of Wenzhou, China.  Bavi was moving toward the northwest at 18 m.p.h. (30 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 952 mb.

The center of Typhoon Bavi made landfall on the east coast of China east of Wenzhou on Saturday.  Typhoon Bavi was the equivalent of a Category 1 hurricane on the Saffir-Simpson Scale at the time of landfall.

The strongest winds were blowing in the eastern side of Typhoon Bavi which was still over the East China Sea.  Winds to typhoon force extended out 90 miles (145 km) in the eastern side of Bavi’s circulation.  Wind to tropical storm force extended out 345 miles (555 km) from the center of Typhoon Bavi.

The Hurricane Intensity Index (HII) for Typhoon Bavi is 13.9.  The Hurricane Size Index (HSI) is 24.9 and the Hurricane Wind Intensity Size Index (HWISI) is 38.8.  Typhoon Bavi is similar in intensity to Hurricane Sandy when Sandy hit the east coast of the U.S. in 2012.  Typhoon Bavi is a little smaller than Sandy was.

Typhoon Bavi will move around the southwestern part of a high pressure system that is over the Western North Pacific Ocean.  The high pressure system will steer Bavi toward the northwest during the next 24 hours.  On its anticipated track, the center of Typhoon Bavi will continue to move inland over Zhejiang.  The center of Bavi’s circulation will pass west of Shanghai on Sunday.

Typhoon Bavi will bring strong winds and heavy rain to Zhejiang during the next few hours.  Heavy rain is likely to cause flash floods in some locations.  Typhoon Bavi could also cause a storm surge of up to 8 feet (2.5 meters) along parts of the east coast of China.

Typhoon Bavi will weaken gradually as it moves farther inland over eastern China.  Even so, Typhoon Bavi will also bring strong winds and heavy rain to Jiangsu as it moves farther to the north on Sunday.

Typhoon Bavi Brings Wind and Rain to Ryukyu Islands

Typhoon Bavi brought wind and rain to the southern Ryukyu Islands on Friday.  At 11:00 p.m. EDT on Friday the center of Typhoon Bavi was located at latitude 25.6°N and longitude 124.1°E which put the center about 165 miles (265 km) east-northeast of Taipei, Taiwan.  Bavi was moving toward the north-northwest at 15 m.p.h. (24 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 953 mb.

A weather station in Ishigakijima Island reported at sustained wind speed of 49 m.p.h. (80 km/h).  A weather station in Nakasuji, Japan reported a sustained wind speed of 53 m.p.h. (85 km/h).

Typhoon Bavi strengthened a little as it approached the southern Ryukyu Islands on Friday.  More thunderstorms formed near the center of Bavi’s circulation.  Concentric eyewalls appeared for a time on radar images from the Japan Meteorological Agency.  A small inner eye and eyewall was surrounded by a much larger outer eyewall that was a remnant from the last eyewall replacement cycle.

The distribution of thunderstorms in Typhoon Bavi continued to be asymmetrical.  Thunderstorms were occurring mostly in bands in the southern half of Bavi’s circulation.  Bands in the northern half of Typhoon Bavi consisted primarily of showers and lower clouds.  Storms near the center of Bavi generated more upper level divergence.  The removal of more mass caused the surface pressure to decrease on Friday.

Typhoon Bavi continued to be a very large typhoon.  Winds to typhoon force extended out 175 miles (280 km) from the center of Bavi’s circulation.  Winds to tropical storm force extended out 370 miles (595 km) from the center of Typhoon Bavi.

The Hurricane Intensity Index (HII) for Typhoon Bavi is 13.9.  The Hurricane Size Index (HSI) is 48.2 and the Hurricane Wind Intensity Size Index (HWISI) is 62.1.  Typhoon Bavi is similar in size and intensity to Hurricane Sandy when Sandy hit the east coast of the U.S. in 2012.

Typhoon Bavi will move through an environment that will be marginally favorable for intensification during the next 12 hours.  Bavi 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.  Typhoon Bavi will move through a region of drier air that is near eastern of Chin.a  The drier air will inhibit intensification.  Typhoon Bavi could maintain its intensity during the next 12 hours.

Typhoon Bavi will move around the southwestern part of a high pressure system that is over the Western North Pacific Ocean.  The high pressure system will steer Bavi toward the northwest during the next 24 hours.  On its anticipated track, the center of Typhoon Bavi will reach the east coast of China near Wenzhou in 12 hours.

Typhoon Bavi will bring strong winds and heavy rain to Zhejiang.  Heavy rain is likely to cause flash floods in some locations.  Typhoon Bavi could also cause a storm surge of up to 10 feet (3 meters) along parts of the east coast of China.
