Taiwan: Adverse weather forecast across most regions through at least Feb. 24
Adverse weather forecast across much of Taiwan through at least Feb. 24. Possible transport, business, and utility disruptions.
Event
Heavy rainfall and cold temperatures are forecast across parts of central and northern Taiwan through at least Feb. 24, as well as strong winds and rough seas for most coastlines. The Taiwan Central Weather Bureau has issued the following warnings:
Orange Extremely Heavy Rain warnings (the third highest level on a four-tier scale): central and western Taichung Special Municipality.
Yellow Heavy Rain warnings: across Keelung City, New Taipei, Taipei, and Taoyuan special municipalities, and Yilan County; as well as eastern Chiayi, central and eastern Hsinchu, central and western Miaoli, most of Nantou, and far southeastern Yunlin counties.
Orange Cold Surge Advisories (the middle level on a three-tier scale): across New Taipei, Taichung, and Taoyuan special municipalities and Kinmen and Lienchiang counties.
Strong Wind Advisories: across all coastlines with the exception of Kaohsiung special municipality.
Officials could update and extend the coverage of weather alerts in the coming days.
Hazardous Conditions
Sustained heavy rainfall could trigger flooding in low-lying communities near rivers, streams, and creeks. Urban flooding is also possible in developed areas with easily overwhelmed stormwater drainage systems. Sites located downstream from large reservoirs or rivers may be subject to flash flooding after relatively short periods of intense rainfall. Landslides are possible in hilly or mountainous areas, especially where heavy rainfall has saturated the soil. Disruptions to electricity and telecommunications services are possible where significant flooding or landslides impact utility networks.
Transport
Floodwaters and debris flows may render some bridges, rail networks, or roadways impassable, impacting overland travel in and around affected areas. Ponding on road surfaces could cause hazardous driving conditions on regional highways. Authorities could temporarily close some low-lying routes that become inundated by floodwaters. Severe weather could also trigger flight delays and cancellations at regional airports. If strong winds trigger hazardous sea conditions, authorities may temporarily suspend port operations or close beach fronts. Flooding could block regional rail lines; freight and passenger train delays and cancellations are likely in areas that see heavy rainfall and potential track inundation.
Localized business disruptions may occur in low-lying areas; some businesses might not operate at full capacity because of flood damage to facilities, possible evacuations, and some employees' inability to reach work sites.
Advice
Monitor local media for weather updates and related advisories. Confirm all transport reservations and business appointments before travel. Make allowances for localized travel delays and potential supply chain disruptions where flooding has been forecast. Do not drive on flooded roads. Charge battery-powered devices in the case of prolonged electricity outages.
