Japanese weather forecasters are warning that a very powerful typhoon is bringing heavy rain and strong winds to islands in the Pacific Ocean south of Tokyo.
The Meteorological Agency says Typhoon Lionrock was moving northeast at a speed of 30 kilometers per hour over waters near the Izu Island chain at 6AM on Monday.
The typhoon is packing winds of more than 160 kilometers per hour (99.419 mph) near its center.
The storm is already affecting the weather in western Japan. 68 millimeters of rain fell in one hour until 6AM in a town in the southern prefecture of Tokushima.
Officials warn that more than 80 millimeters of rain per hour could fall on the southern island of Shikoku.
After passing through waters between the Izu and Ogasawara Island chains, the typhoon is projected to change course to the northwest. It is expected to approach eastern and northern Japan on Tuesday.
Officials are urging caution for rivers that may overflow their banks, as well as landslides and strong winds.
