Taipei: The Central Weather Administration (CWA) on Sunday issued heavy rain advisories for most of Taiwan, excluding Keelung City and the outlying Penghu, Kinmen, and Lienchiang counties. Earlier in the day, the CWA initially issued the advisories on all of Taiwan proper to warn of the possibility of more than 80 millimeters of rainfall within 24 hours, or more than 40 mm within one hour.
