China: Severe weather forecast to persist across central and eastern regions through at least Sept. 22

Event

Severe weather is forecast to persist across parts of central and eastern China through at least Sept. 22. As of Sept. 20, the China Meteorological Administration has issued a yellow heavy rainfall warning (the second-lowest level on a four-tier scale) across parts of western Hubei, eastern Sichuan, central and eastern Chongqing, northern Guizhou, northwestern Hunan, southeastern Anhui, and western Zhejiang provinces, as well as eastern coastal areas. The heaviest rainfall totals are expected in parts of northeastern Chongqing, where 10-12 cm (3.9-4.7 inches) are possible Sept. 20-21. Hourly rainfall amounts of 2-5 cm (0.8-2 inches) are possible across the affected area, with localized heavier downpours of more than 6 cm (2.5 inches) per hour possible. Strong winds and thunderstorms are also possible across the region. Orange and yellow landslide warnings are also in place for parts of central and southern Shandong, western Hubei. northeastern Sichuan, central and northern Chongqing, and southern Shaanxi provinces.

Disruptions are ongoing in parts of Jiangsu Province as of Sept. 20 after a tornado struck parts of Suqian City Sept. 19. Authorities have reported five fatalities and four others injured due to the tornado. More than 5,500 people were affected, 137 homes destroyed, and more than 1,600 homes damaged by the tornado. More than 400 people in affected parts of the city were temporarily displaced due to damage caused by the tornado.

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.

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 airports in the region. Authorities may temporarily suspend port operations or close beach fronts along the east coast if strong winds trigger hazardous sea conditions. 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.
