Tropical Storm Dujuan is forecast to approach eastern Japan over Silver Week, bringing heavy rain, strong winds and high waves to the Tokyo region after first passing near the Ogasawara and Izu island chains. According to the Japan Meteorological Agency (JMA), the storm was about 170 kilometers south-southeast of Chichijima in the Ogasawara Islands as of 3 p.m. Friday and moving west-northwest at a speed of 35 kph.
Dujuan had a central pressure of 975 hectopascals and maximum sustained winds near its center of 108 kph, with gusts of as much as 162 kph, the agency said. The storm is expected to pass near the Ogasawara Islands from Friday into Saturday before turning north and approaching the Izu Islands on Sunday. It may then shift north-northeast and approach the Pacific coast of eastern Japan from Sunday into Monday.
The JMA warned that the Ogasawara Islands could see as much as 250 millimeters of rain in the 24 hours through noon Saturday. The Izu Islands could receive as much as 200 mm in the following 24 hours, while parts of the Kanto region could see up to 150 mm. Another 200 mm could fall in both Kanto and the Izu Islands during the 24 hours through noon Monday.
