From 1928 to 1930, China was afflicted by a long drought. The subsequent winter of 1930 was particularly harsh, creating large deposits of snow and ice in mountainous areas. In early 1931, melting snow and ice flowed downstream and arrived in the middle course of the Yangtze during a period of heavy spring rain. Ordinarily, the region experienced three periods of high water during the spring, summer and fall, respectively; however, in early 1931, there was a single continuous deluge. By June, those living in low areas had already been forced to abandon their homes. The summer was also characterized by extreme cyclonic activity. In July of that year alone, nine cyclones hit the region, which was significantly above the average of two per year. Four weather stations along the Yangtze River reported rain totalling over 600 mm (24 in) for the month. The water flowing through the Yangtze reached its highest level since record-keeping began in the mid-nineteenth century. That autumn, further heavy rain added to the problem and some rivers did not return to their normal courses until November. The floods inundated approximately 180,000 square kilometres (69,000 sq mi) – an area equivalent in size to England and half of Scotland, or the states of New York, New Jersey, and Connecticut combined. The high-water mark recorded on 19 August at Hankou in Wuhan showed water levels 16 m (53 ft) above the average, an average of 1.7 m (5.6 ft) above the Shanghai Bund. In Chinese, this event is commonly known as 江淮水灾, which roughly translates to "Yangtze-Huai Flood Disaster." This name, however, fails to capture the massive scale of flooding. Waterways throughout much of the country were inundated, particularly the Yellow River and Grand Canal. The eight most seriously affected provinces were Anhui, Hubei, Hunan, Jiangsu, Zhejiang, Jiangxi, Henan and Shandong. Beyond the core flood zone, areas as far south as Guangdong, as far north as Manchuria, and as far west as Sichuan were also inundated.
