South Korea: Adverse weather forecast in eastern North Gyeongsang Province through at least Nov. 23
Heavy rainfall forecast in eastern North Gyeongsang Province, South Korea through Nov. 23. Flooding and associated disruptions ongoing.
Event
Heavy rainfall is forecast across parts of eastern North Gyeongsang Province through at least Nov. 23. As of Nov. 22, the Korea Meteorological Administration (KMA) has issued a heavy rain warning for Yeongdeok County and heavy rain advisories have been issued for the plains of Uljin County and Pohang City. Three-hourly rainfall totals of more than 9 cm (3.5 inches) and 12-hourly totals of more than 18 cm (7 inches) are possible in the warning area. Officials could update and possibly extend the coverage of the relevant weather alerts over 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 the soil has become saturated by heavy rainfall.
Authorities could issue mandatory evacuation orders for flood-prone communities over the coming days. Disruptions to electricity and telecommunications services are possible where significant flooding or landslides impact utility networks.
Transport
Floodwaters and debris flows could render some bridges, rail networks, or roadways impassable, impacting overland travel 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.
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.
