GUANGZHOU, Aug. 3 (Xinhua) -- South China's Guangdong Province has activated a Level-IV emergency response in anticipation of torrential rain, the provincial headquarters for flood, drought and wind control said on Sunday morning.

From Sunday to Tuesday, Guangdong is expected to experience torrential rains, which could lead to flooding, mountain torrents, geological hazards and waterlogging in urban and rural areas, according to the provincial meteorological service.

Parts of coastal cities and counties in eastern Guangdong and the southern Pearl River Delta are expected to experience extraordinarily heavy downpours.

The headquarters required local authorities to intensify analysis and promptly activate emergency responses to ensure public safety and minimize disaster losses.

China has a four-tier emergency response system for flood control, with Level I being the most severe. ■
