Typhoon Lan Makes Landfall in Honshu

Typhoon Lan made landfall in Honshu on Monday. At 5:00 p.m. EDT on Monday the center of Typhoon Lan was located at latitude 33.7°N and longitude 135.9°E which put it about 15 miles (25 km) north of Shingu, Japan. Lan was moving toward the northwest at 8 m.p.h. (13 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 970 mb.

The center of Typhoon Lan made landfall in Wakayama Prefecture near Shingu on Monday. A circular eye with a diameter of 50 miles (80 km) was at the center of Lan’s circulation. A broken ring of thunderstorms surrounded the eye and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the core of Typhoon Lan.

There was still a large circulation around Typhoon Lan. Winds to typhoon force extended out 70 miles (110 km) from the center of Lan’s circulation. Winds to tropical storm force extended out 145 miles (235 km) from the center of circulation. The Hurricane Intensity Index (HII) for Typhoon Lan was 13.9. The Hurricane Size Index (HSI) was 23.0 and the Hurricane Wind Intensity Size Index (HWISI) was 36.9. Typhoon Lan was capable of causing widespread serious damage.

Typhoon Lan will move around the western part of a high pressure system over the Western North Pacific Ocean during the next 24 hours. The high pressure system will steer Lan toward the north-northwest during the next 24 hours. On its anticipated track, Typhoon Lan will move across Honshu during the next 24 hours. The center of Lan’s circulation will pass near Osaka in a few hours. The center of circulation will also pass west of Kyoto before Lan moves over the Sea of Japan.

Although Typhoon Lan will weaken as it moves across Honshu, Lan will produce strong gusty winds and locally heavy rain over parts of Honshu. Lan will drop heavy rain over Wakayama, Nara, Osaka, Shiga, Kyoto, Hyogo, Tottori, Okayama and Fukui Prefectures. Heavy rain could cause flash floods in some locations. Wind and rain are also likely to cause loss of electricity in widespread areas.

Elsewhere over the Western North Pacific Ocean, Tropical Storm Dora continued to weaken east of Wake Island. At 5:00 p.m. EDT on Monday the center of Tropical Storm Dora was located at latitude 20.9°N and longitude 168.3°E which put it about 145 miles (235 km) east of Wake Island. Dora was moving toward the north-northwest 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 1004 mb.

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.
