Most of the deaths occurred in Yongjia County, administered by Wenzhou City, where torrential downpours caused a landslide that blocked rivers. The barrier lake burst and flooded people away, Xinhua news agency reported.
Nearly 1.08 million people have been evacuated to safe places, and close to five million people in Zhejiang were affected, according to the details provided by the provincial flood control headquarters.
Lekima, the ninth typhoon of this year, landed around 1:45 a.m. (local time) on Saturday in Zhejiang, bringing heavy rainstorms and triggering flash floods.

Typhoon Lekima is expected to move northwards.
It is expected to make a second landing along the coastline in Shandong on late Sunday, bringing strong wind and heavy downpours, the National Meteorological Center has issued a warning.
