Heavy downpours struck the region late Saturday and continued until midday Sunday, with Guankouwan and Hanjiagou villages logging 296.7 millimeters (11.6 inches) and 256.9 mm of extraordinary rainstorms, respectively, Beijing-based Xinhua News reported.
Meteorological authorities warned that, considering the short interval between the current and previous rounds of heavy rainfall, the continuous precipitation poses a higher risk of inducing geological disasters, including landslides, collapses and debris flows.
Authorities activated a Level-III emergency response for geological disasters in the Yongchuan district as relevant departments are carrying out an emergency rescue operation to find missing persons.
