Residents in northern Japan were battening down the hatches as powerful Typhoon No. 5 remained on course to make landfall in the Tohoku region on Aug. 12.

Linear rainbands that cause prolonged downpours were forecast in Aomori, Iwate and Miyagi prefectures from late Aug. 11 to the following morning.

The Japan Meteorological Agency warned of landslides, swollen rivers, storms and high waves from northern to eastern Japan, mainly in the Tohoku region.

It said the typhoon was over the sea east-southeast of Ishinomaki, Miyagi Prefecture, as of 3 p.m. on Aug. 11 and moving northwest at a speed of about 10 kph.

It had a central pressure of 980 hectopascals and maximum instantaneous wind speeds near the center of 126 kph.

The total rainfall in the Tohoku region is likely to exceed the normal August monthly total, with 300 millimeters of 24-hour rainfall expected until 6 p.m. on Aug. 12.

The typhoon, along with gales at sea, is expected to whip up waves to heights of around 7 meters, officials said.
