Typhoon Jongdari Makes Landfall on Honshu

Typhoon Jongdari made landfall on Honshu near Ise in the Mie Prefecture on Saturday.  The maximum sustained wind speed was 80 m.p.h. (130 km/h) at the time of landfall.  Jongdari weakened to a tropical storm after the center moved over Honshu.  At 5:00 p.m. EDT on Saturday the center of Tropical Storm Jongdari was located at latitude 34.7°N and longitude 135.0°E which put it about 20 miles (30 km) southwest of Kobe, Japan.  Jongdari was moving toward the west-northwest at 25 m.p.h. (40 km/h).  The maximum sustained wind speed was 70 m.p.h. (110 km/h) and there were wind gusts to 85 m.p.h. (135 km/h).  The minimum surface pressure was 980 mb.

The center of Typhoon Jongdari made landfall in the Mie Prefecture on Honshu near Ise and Toba.  Jongdari then moved west-northwest near Matsusaka and Tsu.  It passed near Nara and Osaka before moving to its current position southwest of Kobe.  Typhoon Jongdari brought gusty winds and it dropped locally heavy rain over parts of the Mie, Nara, Shiga, Kyoto, Osaka and Hyogo Prefectures.  The ground in some of those places is very moist from recent rains and flash flooding could occur if more heavy rain falls.  The relatively rapid movement of Tropical Storm Jongdari will help to reduce the amount of rain that falls over specific locations.

Tropical Storm Jongdari will continue to weaken as it moves over western Honshu and northern Kyushu.  Jongdari is moving around the northern side of an upper level low south of Japan.  The upper level low will steer Tropical Storm Jongdari quickly to the west during the next 12 hours.  Jongdari will move southwest on Sunday when it moves around the northwestern part of the upper low.  On its anticipated track Tropical Storm Jongdari will move near Okayama, Hiroshima, Yamaguchi, Kitakyushu and Fukuoka.  The tropical storm will continue to drop locally heavy rain while it weakens over western Japan.

Typhoon Jongdari Turns Toward Honshu

Typhoon Jongdari turned toward Honshu on Friday.  At 5:00 p.m. EDT on Friday the center of Typhoon Jongdari was located at latitude 31.0°N and longitude 143.7°E which put it about 415 miles (665 km) southeast of Tokyo, Japan.  Jongdari was moving toward the north at 24 m.p.h. (39 km/h).  The maximum sustained wind speed was 105 m.p.h. (170 km/h) and there were wind gusts to 125 m.p.h. (205 km/h).  The minimum surface pressure was 957 mb.

An upper level low west of Typhoon Jongdari was affecting the circulation.  Winds blowing around the eastern side of the upper low were cutting under the upper level divergence at the top of the circulation of Jongdari.  In addition, drier flowing around the southern half of the upper low was being pulled into the western side of the circulation of Typhoon Jongdari.  The effects of the upper low were causing the circulation of Typhoon Jongdari to become asymmetrical.  Many of the stronger thunderstorms and stronger winds were occurring in bands in the eastern half of the circulation.  Bands in the western half of the circulation consisted primarily of showers and lower clouds.  With fewer strong thunderstorms in the western part of the typhoon with downdrafts to bring stronger winds to the surface the wind field was also becoming asymmetrical.  Winds to typhoon force extended out about 100 miles (160 km) from the center of circulation on the eastern side of Jongdari, but they only extended out about 50 miles (80 km) on the western side.  Winds to tropical storm force extended out about 230 miles (370 km) to the east of the center, but only extended out about 170 miles (280 km) to the west of the center of circulation.

The upper level low will continue to affect Typhoon Jongdari.  Jongdari will move over water where the Sea Surface Temperature is near 28°C.  So, there will be sufficient energy in the upper ocean to support a strong typhoon.  However, the upper low will inhibit upper level divergence to the west of the circulation.  Upper level divergence will be strong to the southeast of Typhoon Jongdari.  Drier air flowing around the upper low will inhibit the formation of thunderstorms in bands in the southwestern part of the circulation.  Typhoon Jongdari is likely to weaken slowly, although it could maintain its intensity at times as it moves around the northern side of the upper low.

The upper low will also steer Typhoon Jongdari during the weekend.  Jongdari will turn more toward the west-northwest when it moves around the northern part of the upper low.  On its anticipated track Typhoon Jongdari could pass south of Tokyo in about 18 hours.  The center of Jongdari could be very close to Hamamatsu in about 24 hours.  It could make landfall near Matsuzaka in a little over a day.  Typhoon Jongdari could pass very close to Osaka and Kobe and it could pass just south of Kyoto.  Heavy rain fell on parts of Japan earlier this month and Typhoon Jongdari could cause serious flooding in some locations.

Typhoon Noru Skirts Coast of Shikoku on Way to Honshu

The eye of Typhoon Noru skirted the coast of Shikoku on Sunday as it moved closer to a landfall on Honshu.  At 11:00 p.m. EDT on Sunday the center of Typhoon Noru was located at latitude 33.6°N and longitude 134.5°W which put it about 85 miles (135 km) southwest of Osaka, Japan.  Noru was moving toward the northeast at 14 m.p.h. (22 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 970 mb.

The structure of Typhoon Noru improved on Sunday.  The circulation contracted around an eye with a diameter of approximately 20 miles (32 km).  They eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in the ring of storms.  Additional spiral bands were revolving around the core of Typhoon Noru.

An upper level trough northwest of Japan steered Typhoon Noru toward the northeast on Sunday.  The eye of Noru moved near the south coast of Shikoku.  The eye passed south of Kochi and very near Muroto, Toyo and Kainan.  Typhoon Noru brought gusty winds and heavy rain to the southern parts of Shikoku.

Typhoon Noru is expected to continue to move toward the northeast on Monday.  On its anticipated track the center of Typhoon Noru is expected to skirt the east coast of Shikoku and make landfall on Honshu near Wakayama.   After it makes landfall, Typhoon Noru is forecast to pass near Osaka and Kyoto.  Typhoon Noru will weaken as it moves across Honshu, but it will produce gusty winds and locally heavy rain.  The rain could cause floods in some locations.
