Typhoon No. 10 is on course to batter the Kinki region with warning-level rainfall, mainly around Aug. 27-28, authorities said.

The typhoon originated near the Mariana Islands in northwestern Micronesia on Aug. 22. It was moving northwestward at 30 kph over the sea south of Japan as of 9 a.m. on Aug. 25.

The Osaka District Meteorological Observatory predicted the typhoon will reach southern Kyushu at 9 a.m. on Aug. 27, then change course to a north-northeasterly direction, reaching waters off the coast of Shikoku at 9 a.m. on Aug. 28 and making landfall in the Shikoku or Kinki regions the same day.

The weather station forecast 150 millimeters of rain in the southern Kinki region in the 24-hour period until noon on Aug. 27 and 100 mm in the central Kinki region.

It said 200 mm of rain could be expected until noon on Aug. 28 in central Kinki and 300 mm in southern Kinki.

A storm surge warning may be issued for the Kinki region on Aug. 28.

If the path of the typhoon turns eastward, it could cause large-scale damage, like Typhoon No. 21 that hit the Kinki region in 2018 and caused massive damage to agricultural infrastructure.

The Osaka District Meteorological Observatory held a briefing session for local authorities and the media on Aug. 25, urging people in the Kinki region to refrain from going out on Aug. 28 unless it is necessary.
