Heavy rain continued to batter parts of central and eastern China on Wednesday as the remnants of Typhoon Dolphin combined with other weather systems, prompting authorities to maintain orange alerts for torrential rain and geological disasters.

The National Meteorological Center on Wednesday renewed an orange alert for heavy rain, the country's second-highest warning level, forecasting heavy to torrential rain from Wednesday afternoon through Thursday afternoon in parts of Henan, Hubei, Anhui, Zhejiang, Shandong and Hebei provinces, as well as Shanghai, Beijing and Tianjin.

Parts of western and central Henan along mountain areas could see exceptionally heavy rainfall of 250 to 280 millimeters.
