TOKYO (Kyodo) -- Typhoon Leepi weakened to an extratropical depression over waters west of the Kyushu region Friday morning, but the weather agency continued to warn of heavy rain in western Japan.

The Japan Meteorological Agency said the extratropical depression was moving east-northeast at a speed of 30 kilometers per hour over waters west of Kyushu at 9 a.m.

In the village of Umaji, Kochi Prefecture, rainfall reached 354.5 millimeters in 24 hours through early Friday, more than half of the average monthly amount of rainfall in June, the agency said.

Some areas may be hit by up to 60 mm rainfall hourly through Friday evening, the agency said, urging caution against strong winds, high waves, tornadoes as well as thunder.

The 24-hour precipitation through 6 a.m. Saturday is forecast to reach up to 200 mm in Shikoku, up to 150 mm in Kyushu, and up to 120 mm in Kinki centering on Osaka.
