Typhoon No. 15 is forecast to bring heavy rain across wide areas of western and eastern Japan through Sept. 5, raising concerns over landslides, flooding and river overflows.

As of 10 a.m. on Sept. 4, the typhoon was approximately 80 kilometers south of Tanegashima island in Kagoshima Prefecture, traveling north at a speed of 30 kph, according to the Japan Meteorological Agency.

The storm has a central atmospheric pressure of 1,002 hectopascals, with maximum sustained winds of 64.8 kph and gusts reaching 90 kph.

The typhoon is expected to approach Miyazaki Prefecture by the evening, before turning eastward the following day and tracking along the Pacific coast. It is then likely to weaken into an extratropical low-pressure system.

The JMA has also warned of the possibility of linear rainbands developing from the afternoon of Sept. 4 through the following afternoon, particularly across the Kyushu, Shikoku and Tokai regions.

Such rainbands can lead to intense and prolonged rainfall over the same areas, increasing the risk of severe weather disasters.

The maximum 24-hour rainfall amounts forecast by noon on Sept. 5 are 300 mm in Shikoku; 250 mm in Tokai and Kinki regions; 200 mm in northern Kyushu; and 180 mm in southern Kyushu.
