China: Severe weather forecast to continue across multiple regions through at least June 23

Severe weather is forecast to continue across parts of central, eastern, and northeastern China through at least June 23. As of June 22, the China Meteorological Administration (CMA) has issued yellow heavy rain warnings (the second lowest level on a four-tier scale) across parts of Guizhou, Hunan, Hubei, Jiangxi, Anhui, Jiangsu, Zhejiang and Heilongjiang provinces, and in Shanghai, through at least 08:00 June 23. Short-term downpours with hourly totals of 8 cm (3.1 inches) are possible in the affected region. Authorities may extend the warnings at short notice.

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.
