Taipei, Aug. 29 (CNA) Typhoon Nanmadol was downgraded to a tropical storm early Monday, shortly after it made landfall near Dawu in the eastern Taiwan county of Taitung, the Central Weather Bureau (CWB) said.

The storm is likely to continue to lose strength and will move offshore somewhere between Taichung and Tainan by midnight, forecasters said.

At 10 a.m., Nanmadol was centered 40 kilometers north-northeast of Kaohsiung in southern Taiwan. It was moving north-northwest at 9 kph, packing maximum sustained winds of 108 kph with gusts of up to 137 kph.

Heavy winds and rain continued in areas south of Miaoli and Hualien, which are within the storm's 180-km radius, the CWB said. Southwestern Taiwan is expected to experience increasing rainfall in the coming hours, it said.

Despite Nanmadol's weakening, rainfall from the storm can reach "extremely torrential" levels, the CWB said. It forecast rainfall in excess of 350 mm in a 24-hour period in the northeastern, eastern and southeastern regions. In mountainous areas in northern and southern Taiwan, the volume of 24-hour rainfall could be higher than 200 mm, it said.

From Sunday to 10 a.m. Monday, Nanmadol had dumped 528 mm of rain in Bruwan, Hualien County; 517 mm in Hengchun, Pingtung County; 449 mm in Jhihben, Taitung County; 292 mm in Sidu, New Taipei City; 275 mm in Paiyun, Kaohsiung City; and 265 mm in Taiping Mountain, Yilan County, according to CWB data.
