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.

Tropical Storm Krosa Brings Wind and Rain to Southwest Japan

Large Tropical Storm Krosa brought wind and rain to parts of southwestern Japan on Wednesday night.  At 11:00 p.m. EDT on Wednesday the center of Tropical Storm Krosa was located at latitude 33.2°N and longitude 132.9°E which put it about 20 miles (30 km) south-southwest of Uwajima, Japan.  Krosa was moving toward the north at 13 m.p.h. (20 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 975 mb.

The center of large Tropical Storm Krosa was near the southwestern coast of Shikoku on Wednesday night.  The strongest winds were blowing in rainbands that were east of the center of circulation.  Winds to tropical storm force extended out about 260 miles (420 km) from the center of circulation.  The wind was weaker in the western half of Krosa.

Heavy rain was falling on the south facing slopes of Shikoku where the wind was blowing up the slopes.  Heavy rain was also falling on south facing slopes in Wakayama, Mie, Nara and Shiga prefectures in Honshu.  Prolonged heavy rainfall could cause flash floods in some locations.

Tropical Storm Krosa is forecast to move north-northeast across Shikoku and southwestern Honshu.  Krosa will weaken when it moves over land, but it will continue to drop heavy rain over parts of southwestern Japan on Thursday.  A weaker Tropical Storm Krosa is forecast to move over the Sea of Japan later on Thursday.
