Typhoon Shanshan has brushed parts of Japan, including Tokyo, with strong winds and locally heavy rain but is beginning to head out into the open western Pacific Ocean.

While the core of Shanshan, including its ragged eyewall with its strongest winds is staying offshore from eastern Japan, the typhoon, currently equivalent in strength to a Category 1 hurricane on the Saffir-Simpson Hurricane Wind Scale, has brought some stronger wind gusts, rain, and high surf to eastern Japan.

Chichibu, about 40 miles northwest of downtown Tokyo, picked up almost 7 inches of rainfall in the 48 hours ending early Thursday morning (Japan time), according to the Japan Meteorological Agency. Some 50 to 60 mph wind gusts were measured along the coast in Chiba Prefecture, east of Tokyo.

Tokyo's Narita airport has seen winds gust up to 45 mph.

Shanshan's center is expected to roughly parallel the Japanese coasts of Chiba and Ibaraki Prefectures through Thursday before turning sharply east-northeast and accelerating into the open waters of the north Pacific Ocean.

Current Storm Status and Projected Path

Locally heavy rain capable of flash flooding, strong winds can be expected into Thursday near the path of Shanshan. 

Dangerous surf and some coastal flooding can be expected near the path of Shanshan's center along the coast.

Shanshan Rainfall Outlook

Fortunately, Shanshan's track is far enough east to spare still-recovering, flood-ravaged southwestern Japan more heavy rain.

The past month has been very frantic in Japan, where disastrous flooding, deadly heat and Typhoon Jongdari all impacted the country in July.
