TOKYO -- Residents should watch out for landslides, flooding in low-lying areas and overflowing rivers as heavy rain brought by Typhoon Chanthu threatens western through northern Japan on Sept. 16 to 18, the Japan Meteorological Agency (JMA) has announced.
The JMA is also warning of strong winds and high waves in western Japan on Sept. 17-18, and extremely strong winds for eastern Japan on Sept. 18. Typhoon Chanthu, the 14th tropical storm of the year, was about 380 kilometers west-southwest of the Goto Islands in the East China Sea off the Japanese island of Kyushu as of 3:00 p.m. on Sept. 16, moving north-northeast at about 15 kilometers per hour.
The air pressure at its center was 990 hectopascals, with a maximum sustained windspeed of 25 meters per second (90 km/h) and gusts topping out at 35 m/s (126 km/h). The stormfront stretches from the East China Sea through southwest Japan's Kyushu to the seas east of the country.
The storm is projected to make landfall in western Japan on the afternoon of Sept. 17. The JMA predicts it will move on to eastern Japan the following day, taking on characteristics of a warm low-pressure system over the course of the day.
In the 24-hour period to 6 p.m. on Sept. 17, the northern Kyushu region is expected to see 250 millimeters of rain, while 200 mm is forecast for the Shikoku region, 150 mm for southern Kyushu, 120 mm for the Kinki region, and 100 mm for the Tokai area in central Japan.
In the 24 hours up to 6 p.m. on the following day, the JMA is predicting 200-300 millimeters of rain for the Kanto-Koshin, Tokai, Kinki and Shikoku regions, 100-200 mm for the Tohoku, Hokuriku and Chugoku areas, and 100-150 mm for northern Kyushu.
In addition to landslide and flood risks, the JMA is calling on people to be on their guard against lighting strikes and severe winds including possible tornadoes.
