Changsha sits in the Yangtze River basin, where a distinct early-summer ‘plum rain’ (meiyu) season brings weeks of sustained, humid rainfall in June and July, followed by a secondary risk from the remnants of typhoons that track inland from the East China Sea through late summer.
Built along the Xiang River in Hunan, the city has experienced notable river flooding during especially wet monsoon years. The combination of saturated ground from the plum rains and sudden downpours later in the season means river and lake levels can rise quickly, so radar is widely used alongside river-gauge data to anticipate flooding in Hunan.
