Taipei, The periphery of Typhoon Mangkhut will cause heavy rainfall in parts of eastern and southern Taiwan on Saturday, the Central Weather Bureau (CWB) said.
Mangkhut had reached the South China Sea as of 9 a.m. Saturday, after making landfall in northern Philippines hours earlier, the bureau said.
As of 11 a.m., it was located 420 kilometers south-southwest of Eluanbi on Taiwan's southernmost tip, packing maximum sustained winds of 173 kilometers per hour and moving in a west-northwesterly direction at 25 kph, CWB data showed.
It is posing a threat to the Bashi Channel as well as waters off Taiwan's southeastern coasts and the southern part of the Taiwan Strait, the bureau said.
Due to Mangkhut's periphery, Hualien and Taitung counties in eastern Taiwan are expected to see extremely heavy rain, defined as accumulated rainfall of between 200mm and 350mm over 24 hours, or more than 100mm in one hour, the bureau said.
Heavy rain is expected in Yilan, Kaohsiung and Pingtung, meaning accumulated rainfall of between 80mm and 200mm over 24 hours, or more than 40mm in one hour, according to the CWB.
Mangkhut's periphery, meanwhile, could cause foehn wind -- a type of dry, warm wind -- in western Taiwan, with temperatures in Miaoli, Taichung, Nantou and Changhua likely to hit 38 degrees Celsius or higher, the bureau said.
Temperatures of 36-38 degrees are forecast in Hsinchu, Chiayi, Yunlin, Kaohsiung and Tainan as well as the outlying island of Kinmen, it added.
Taiwan's coastal regions can also experience high waves and strong winds reaching 9-11 on the Beaufort scale, according the to CWB.
