An additional 12 people were recorded dead from the storm, including seven from Zhejiang province and five from Shandong, with 16 people missing, according to data from provincial emergency bureaus and state media.
State broadcaster CCTV had put the death toll at 32 on Sunday (August 11).
Typhoon Lekima made landfall early on Saturday in China's Zhejiang province, with winds gusting up to 187 kmh (116 mph).
The center of the storm has since traveled north through Shandong and off the coast.
Many of the earlier deaths occurred when a natural dam collapsed in Zhejiang after a deluge of 160 mm (6.2 inches) of rain within three hours.
The Shandong Emergency Management Bureau said more than 180,000 people were evacuated in the province, adding to an earlier evacuation of roughly 1 million people in Zhejiang and Jiangsu provinces as well as the financial hub of Shanghai.
