Chugoku and Shikoku regions in path of Severe Tropical Storm Nanmadol

Severe Tropical Storm Nanmadol is moving over western Japan, bringing violent winds to the regions of Chugoku and Shikoku, as well as part of Kyushu.

The heavy rain that pounded Miyazaki Prefecture, southwestern Japan, and elsewhere has caused floods and cliff collapses.

The emergency heavy rain warning for Miyazaki Prefecture was downgraded to a warning late Monday morning. But floods have been reported over wide areas, while the rainfall has saturated the ground.

Rain and wind are intensifying in Chugoku and Shikoku; some parts of these regions are facing extreme risk of mudslides as Nanmadol approaches.

The Meteorological Agency says that as of 3 p.m. on Monday, Nanmadol was located near the city of Oda, Shimane Prefecture, western Japan, and moving northeast at a speed of 30 kilometers per hour.

The severe tropical storm has a central atmospheric pressure of 975 hectopascals and a maximum wind speed of 108 kilometers per hour.

The agency is warning people in affected areas to watch out for landslides, flooding in low-lying areas and swollen rivers.

In Hiroshima Prefecture, a record 367 millimeters of rain was observed in the Tsuta district in Hatsukaichi City during the 24 hours through 2 p.m.

Rainclouds are developing over Kinki, Tokai and Kanto regions.

Flood risk information has been issued for some rivers in Hiroshima, Yamaguchi and Shimane prefectures.

The storm brought strong winds to the Kyushu and Shikoku regions. Gusts of nearly 120 kilometers an hour were also recorded in Wakayama City, western Japan, before 2:30 p.m. on Monday.

Nanmadol is expected to move northeast near Honshu on Tuesday. As the storm is accompanied by developed rainclouds, downpours are expected mainly in regions bordering the Pacific Ocean in western and eastern Japan.

Bands of heavy rain may cause downpours in northern Kyushu, Chugoku and Shikoku regions on Monday, in Kinki region through Tuesday morning and in Tokai region from Monday night through Tuesday morning.

Rainfall in the 24-hour period through Tuesday noon could be up to 400 millimeters in Tokai, up to 300 millimeters in Kinki and Kanto-Koshin. Shikoku could see as much as 250 millimeters, and Chugoku, Hokuriku, Tohoku and Hokkaido up to 150 millimeters.

Violent storm conditions are expected over most of western Japan on Monday. The wind can intensify in regions far from Nanmadol. Winds of up to 108 kilometers an hour are expected in northern Kyushu and Chugoku, as well as Shikoku and Kinki regions. Southern Kyushu, Hokuriku and Tokai can expect wind speeds up to 90 kilometers an hour.

Waves 10 meters high are expected in waters surrounding Shikoku, while the seas off northern Kyushu, Kinki and Chugoku are expected to be rough.

Storm surges also cause for concern. Alerts have been issued in regions facing the Seto Inland Sea. A record-level storm surge is expected Monday night in the waters of Harimanada at full tide.

There is a risk of water breaching levees, which may may result in sudden flooding. Officials are urging residents near the coast and low-lying areas facing rivers to take extra care.
