Typhoon Dolphin Hits Eastern China

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

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 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 Lekima Makes Landfall in China

Typhoon Lekima made landfall in China about 200 miles (320 km) south of Shanghai on Friday.  At 5:00 p.m. EDT on Friday the center of Typhoon Lekima was located at latitude 28.8°N and longitude 121.2°E which put it about 195 miles (315 km) south of Shanghai, China.  Lekima was moving toward the north-northwest at 12 m.p.h. (19 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 960 mb.

The inner eye of Typhoon Lekima made landfall on the east coast of China in Zhejiang province about 200 miles (320 km) south of Shanghai on Friday.  Lekima was the the equivalent of a large, major hurricane at the time of landfall.  Winds to typhoon force extended out about 70 miles (110 km) from the center of circulation.  Winds to tropical storm force extended out about 230 miles  (370 km) from the center.  Typhoon Lekima continued to exhibit two concentric eyewalls at the time of landfall.  The strongest winds were occurring around the small inner eye, but winds to typhoon force were also occurring in the large outer eyewall.  The double eyewall structure contributed to the large circulation around Lekima.

Typhoon Lekima will move around the western end of a subtropical ridge over the Western North Pacific Ocean.  The ridge will steer Lekima a little to the west of due north.  On its anticipated track the center of Typhoon Lekima will remain inland, but it will also stay near the coast.  On its anticipated track the center of Typhoon Lekima will pass just to the west of Shanghai in 18 to 24 hours.  Lekima will weaken slowly while it moves northward.  The large size of the circulation and the fact that a portion of the circulation will remain over the Yellow Sea will lengthen the time it takes for the circulation to spin down.  Lekima is likely to be a tropical storm by the time the center nears Shanghai.  Typhoon Lekima will bring gusty winds and drop locally heavy rain over Zhejiang, Jiangsu and Shandong provinces.  Flash flooding is likely in places that receive prolonged heavy rain.

Elsewhere over the Western North Pacific Ocean, Typhoon Krosa remained stalled south of Iwo To.  At 5:00 p.m. EDT on Friday the center of Typhoon Krosa was located at latitude 22.4°N and longitude 141.3°E which put it about 175 miles (280 km) south of Iwo To.  Krosa was moving toward the north at 2 m.p.h. (3 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. (170 km/h).  The minimum surface pressure was 975 mb.  Typhoon Krosa has been nearly stationary long enough to mix cooler water to the surface, which is why it weakened during the past 24 hours.  Krosa is forecast to move toward Iwo To during the next 24 to 36 hours.
