Tropical Storm Lupit Brings Rain to Japan

Tropical Storm Lupit brought rain to Japan on Sunday. At 11:00 a.m. EDT on Sunday the center of Tropical Storm Lupit was located at latitude 32.3°N and longitude 131.6°E which put it about 20 miles (30 km) southwest of Miyazaki, Japan. Lupit was moving toward the east-northeast at 26 m.p.h. (42 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 Lupit made landfall on the coast of Kyushu near Kagoshima on Sunday. Lupit was being steered quickly toward the east-northeast by an upper level trough near the Korean Peninsula. The trough was producing strong southwesterly winds that were blowing toward the top of Lupit’s circulation. Those winds were causing strong vertical wind shear and they were affecting the distribution of rain in Tropical Storm Lupit. Most of the heavier rain was falling in bands north and east of the center of Lupit. The heavier rain was falling over Shikoku, northern Kyushu and southwestern Honshu. Bands south and west of the center of circulation consisted primarily of showers and lower clouds. The strongest winds were occurring in the southern half of Tropical Storm Lupit. Winds to tropical storm force extended out 160 miles (260 km) on the south side of Lupit. The winds in the northern half of the circulation were blowing at less than tropical storm force.

The trough near the Korean Peninsula will steer Tropical Storm Lupit quickly toward the northeast during the next 36 hours. On its anticipated track the center of Lupit will move over the southern Sea of Japan. The center of Tropcial Storm Lupit could be near northern Honshu in 36 hours. Rain will spread over the rest of Honshu and Hokkaido during the next two days. Locally heavy rain could cause flash floods in some locations.

Tropical Storm Lupit will move through an environment only marginally favorable for intensification. Lupit will move over water in the Sea of Japan where the Sea Surface Temperatures are near 28°C. However, the upper level trough will continue to cause strong vertical wind shear. The lower part of Lupit’s circulation will also be disrupted while it passes over land. Tropical Storm Lupit is not likely to strengthen significantly and it could weaken if the center does not move over the Sea of Japan.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Mirinae was moving eastward away from Japan. At 11:00 a.m. EDT on Sunday the center of Tropical Storm Mirinae was located at latitude 36.6°N and longitude 144.7°E which put it about 230 miles (370 km) east-northeast of Tokyo, Japan. Mirinae was moving toward the northeast at 18 m.p.h. (30 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 990 mb.

Tropical Storm Lupit Drops Very Heavy Rain on Taiwan

Tropical Storm Lupit dropped very heavy rain on Taiwan on Friday. At 5:00 p.m. EDT on Friday the center of Tropical Storm Lupit was located at latitude 25.1°N and longitude 120.5°E which put it about 100 miles (160 km) west of Taipei, Taiwan. Lupit was moving toward the east at 7 m.p.h. (11 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.

Bands of rain on the eastern side of Tropical Storm Lupit dropped very heavy rain over much of Taiwan on Friday. Radar estimates of the rainfall by Taiwan’s Central Weather Bureau were as high as two feet (0.6 meters) in some locations. Southerly and southeasterly winds on the eastern side of Tropical Storm Lupit were pushing air up the slopes of mountains on Taiwan. The enhanced rising motion was contributing to prolonged periods of very heavy rain. The very heavy rainfall was creating a very high danger of widespread flash floods.

Tropical Storm Lupit began to strengthen slowly after the center of circulation moved over the Taiwan Strait. The circulation around Lupit was asymmetrical. The strongest thunderstorms and highest wind speeds were in bands on the eastern side of Tropical Storm Lupit. Bands in the western half of Lupit consisted primarily of showers and lower clouds. Northerly winds circulating around the western side of the tropical storm were transporting drier air into the western half of Lupit. Winds to tropical storm force extended out 80 miles on the eastern side of Lupit. The in the western side of the circulation were blowing at less than tropical storm force.

Tropical Storm Lupit will move around the northwestern part of a high pressure system over the Western North Pacific Ocean. The high will steer Lupit toward the east during the next 12 hours. On its anticipated track the center of Tropical Storm Lupit could be near Taipei in six hours. Lupit will continue to drop very heavy rain over Taiwan during the next 12 hours and the risk of flash floods will be very high. The high pressure system will steer Tropical Storm Lupit toward the northeast during the weekend. Lupit could also bring gusty winds and heavy rain to portions of the Ryukyu Islands.

Tropical Storm Lupit will move through an environment somewhat favorable for intensification during the next several days. Lupit will move over water where the Sea Surface Temperatures are near 28°C. It will move under the northeastern part of an upper level ridge. The upper level winds are weaker in that part of the ridge and there will be little vertical wind shear. Tropical Storm Lupit is likely to intensify during the weekend unless the center passes over northern Taiwan. If the center crosses northern Taiwan, then mountains will disrupt the low level circulation.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Mirinae was spinning south of Japan and Tropical Storm Nida was speeding away to the east of Japan. At 5:00 p.m. EDT on Friday the center of Tropical Storm Mirinae was located at latitude 29.0°N and longitude 137.3°E which put it about 480 miles (775 km) south-southwest of Tokyo, Japan. Mirinae was moving toward the east-northeast at 21 m.p.h. (33 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.

At 5:00 p.m. EDT on Friday the center of Tropical Storm Nide was located at latitude 38.1°N and longitude 156.6°E which put it about 775 miles (1250 km) east-southeast of Misawa, Japan. Nida was moving toward the east-northeast at 22 m.p.h. (35 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 980 mb.

Tropical Storms Lupit, Mirinae and Nida Spin over Active West Pacific

Tropical Storms Lupit, Mirinae and Nida were spinning over an active Western North Pacific Ocean on Thursday. At 11:00 a.m. EDT on Thursday the center of Tropical Storm Lupit was located at latitude 23.8°N and longitude 117.3°E which put it about 25 miles (40 km) southeast of Yunxiao, China. Lupit was moving toward the northeast at 5 m.p.h. (8 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 Lupit was dropping heavy rain along the coast of Fujian province. A band of heavy rain on the eastern periphery of Lupit was just west of Taiwan. Tropical Storm Lupit is forecast to move northeast along the east coast of China during the next 24 hours. Lupit is likely to weaken slowly while the center is near the coast. Tropical Storm Lupit could strengthen during the weekend if the center moves farther over the ocean.

At 11:00 a.m. EDT on Thursday the center of Tropical Storm Mirinae was located at latitude 27.1°N and longitude 129.1°E which put it about 70 miles (110 km) east-northeast of Okinawa. Mirinae was moving toward the east-northeast at 11 m.p.h. (17 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 996 mb.

Tropical Storm Mirinae is forecast to move toward the northeast and to strengthen. Mirinae could be south of Japan by this weekend. Weather conditions in Okinawa and the other Ryukyu Islands should improve when Tropical Storm Mirinae moves farther away.

At 11:00 a.m. EDT on Thursday the center of Tropical Storm Nida was located at latitude 33.9°N and longitude 148.2°E which put it about 490 miles (790 km) east-southeast of Tokyo. Nida was moving toward the north-northeast at 12 m.p.h. (19 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 992 mb. Westerly winds in the middle latitudes are forecast to carry Tropical Storm Nida farther away from Japan during the next few days.
