Heavy rain advisories issued for northern, southern Taiwan

Taipei, Sept. 3 (CNA) The Central Weather Administration (CWA) on Thursday issued heavy rain advisories for parts of northern and southern Taiwan, effective through the night.

Heavy rain, defined as rainfall exceeding 80 millimeters in 24 hours or 40 mm in one hour, is expected in Keelung City and other north coast areas; Yilan, Pingtung, and Taitung counties; mountainous areas of Taipei and New Taipei; Lanyu (Orchid Island); and Ludao (Green Island), the CWA said.

Other parts of Taiwan can expect showers or thundershowers on Thursday and into the night, according to the CWA.

Meanwhile, independent meteorologist Wu Der-rong (吳德榮) said Thursday that the two tropical storms currently over the northeastern Pacific, Saudel and Krovanh, are not expected to directly affect Taiwan on Thursday or Friday.

However, high levels of moisture around Taiwan could trigger severe convection, which is often accompanied by thunder, strong winds, and sudden heavy downpours, he said. Such conditions are most likely to occur in southwestern and northeastern Taiwan on Thursday, Wu said.

Over the weekend, weather conditions are expected to remain unstable across Taiwan, with the possibility of localized showers islandwide and afternoon thundershowers in central and southern Taiwan, Wu said.

The persistent rain in southwestern Taiwan is expected to ease next Monday through Wednesday, while northern and eastern Taiwan may see some showers, he forecast.
