China: Severe weather forecast across parts of eastern China through at least Aug. 14
Heavy rainfall, strong winds, and hail forecast across portions of eastern China through at least Aug. 14. Disruptions possible.
Event
Additional thunderstorms with rounds of strong winds, heavy rainfall, hail, and possible landslides are forecast to occur across portions of eastern China through at least Aug. 14. Heavy rain prompted some localized flooding in parts of the region, including locations in Shanghai's Yangpu District, Aug. 11. As of late Aug. 11, the China Meteorological Administration has issued multiple yellow and orange warnings for heavy rainfall in the region, including in Shanghai and parts of Zhejiang, Anhui, and Jiangsu. Isolated intense storms, potentially containing hail and damaging winds, are possible.
Hazardous Conditions
Any further rounds of 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. Disruptions to electricity and telecommunications services are possible where significant flooding, landslides, or strong winds 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.
Severe weather could also trigger intermittent flight delays and cancellations at regional airports, though these are unlikely to be severe or prolonged. Flooding could block regional rail lines; freight and passenger train delays and cancellations are possible in areas that see heavy rainfall and potential track inundation. Localized business disruptions may occur in low-lying areas.
Advice
Monitor local media for weather updates and related advisories. Out of an abundance of caution, confirm all transport reservations and business appointments before travel. Make allowances for localized travel delays and potential supply chain disruptions where adverse weather has been forecast. Charge battery-powered devices in the case of prolonged electricity outages.
