The Central Weather Bureau (CWB) lifted a land warning for Typhoon Hinnamnor before noon on Sunday as it was gradually moving north toward South Korea and was expected to leave Taiwan in the afternoon, but the CWB warned its periphery could still bring heavy rain.
As of 11 a.m. Sunday, Hinnamnor was located 350 kilometers east-northeast of Taipei, moving north-northeast at a speed of 21 kilometers per hour, according to the CWB.
With a radius of 300 km, the storm was carrying maximum sustained winds of 184 kph and gusts of up to 227 kph, the bureau said.
As the typhoon was skirting around Taiwan’s northeast coast, the area’s Yilan, New Taipei and Keelung cities should brace for heavy rain and strong winds, the CWB warned.
Under the influence of Typhoon Hinnamnor’s peripheral circulation, showers will continue into Sunday in northern and northeastern Taiwan, while brief rain can be expected in central and southern regions, the CWB forecast.
The bureau has issued an extremely heavy rain or torrential rain advisory for mountainous areas of Hsinchu, Miaoli and Nantou counties.
A heavy or extremely heavy rain advisory has been issued for Taipei, New Taipei, Taoyuan, Hsinchu, Miaoli, and Yilan, as well as mountainous areas of Taipei, Yunlin, Chiayi, Nantou and Kaohsiung.
Meanwhile, heavy rain is expected in Keelung, Hsinchu City, Taichung, Nantou, Yunlin, Tainan and Pingtung and extremely heavy rain is likely in Hsinchu, Miaoli and Nantou counties, according to the CWB.
The CWB defines heavy rain as accumulated rainfall of 80 millimeters or more within a 24-hour period or 40 mm or more in an hour, while extremely heavy rain refers to accumulated rainfall of 200 mm or more within 24 hours, and torrential rain refers to accumulated rainfall of 350mm or more.
According to the 24-hour rain forecast released by the CWB Sunday morning for flatland areas, New Taipei, Hsinchu will record the most rain at 50mm-100mm, while less than 80mm is forecast for other areas.
