China's national weather observatory on Saturday issued a red alert for rainstorms, the highest level in its four-tier warning system, as Typhoon Bavi is expected to make landfall along the country's eastern coast early Sunday.
The National Meteorological Center (NMC) warned that heavy to extremely heavy rainfall could affect several regions, forecasting cumulative precipitation of 250 to 500 millimeters in parts of eastern and southern Zhejiang Province and northern Fujian Province.
It added that central and northern parts of Taiwan could receive 250 to 800 millimeters of rainfall as the storm moves across the region.
Chinese authorities have stepped up emergency preparedness measures ahead of the typhoon, including large-scale evacuations, transport disruptions and the deployment of emergency response teams across the eastern coastal provinces.
Earlier, the China Climate Center forecast above-average tropical cyclone activity in July, with several storms expected to make landfall or affect China's coastal regions during the month.
