China: Disruptions due to flooding ongoing across multiple regions as of Aug. 10 /update 2
Disruptions due to flooding ongoing across parts of China as of Aug. 10. Casualties reported; further adverse weather forecast.
Event
Disruptions due to severe flooding and landslides are ongoing across multiple regions of China as of Aug. 10. Heavy rainfall associated with Typhoon Doksuri and the current rainy season has triggered widespread flooding and landslides in northeastern and southeastern regions, particularly across Beijing and Hebei Province. As of Aug. 9, authorities have reported 60 and 37 people missing across Beijing. Hebei, Jilin, and Fujian provinces. At least 200,000 homes have been damaged by flooding, and hundreds of thousands of people have been displaced. Flooding has also led to casualties in parts of central and northern China in recent days; seven fatalities were reported in Sichuan Province following a surge of water in the Longxi River near the Yulin Dam Aug. 9. Three people were killed, and two others are missing, following flash flooding in a mountainous area of Jingtai County in Gansu Province Aug. 10.
Further severe weather is forecast across parts of the country over the coming days. Additional rainfall could trigger further flooding and landslides; areas where the ground is already saturated from previous heavy rainfall are likely to be the most susceptible. The China Meteorological Administration has issued a blue typhoon warning (the lowest level on a four-tier scale) due to Typhoon Kahnun. which is currently moving over the Korean peninsula and is expected to bring heavy rainfall to eastern Heilongjiang and northeastern Jilin provinces. Rainfall totals of 10-20 cm (4-8 inches) are expected in the region Aug. 10-11. Authorities have also issued yellow landslide warnings across parts of southwestern Beijing, eastern Jilin, central Sichuan, western and southern Yunnan, and eastern Qinghai.
Hazardous Conditions
Further sustained heavy rainfall could trigger additional 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 additional 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 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. 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.
Health
Flooding could heighten the threat of disease outbreaks. Backflow from drains mixed with floodwaters can become trapped in open areas when inundations recede. These stagnant pools often become a breeding ground for mosquitoes and bacteria, increasing the incidence of insect- and water-borne diseases. Exposure to contaminated water from inundated industrial sites, sewer systems, and septic tanks also poses a significant health threat.
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.
