BEIJING - The National Meteorological Center (NMC) on Sunday issued an orange alert for the approaching super typhoon Dujuan, which is expected to batter China's southeastern regions.

Dujuan will land in coastal province of Fujian on Tuesday morning after sweeping across Taiwan, bringing gales, torrential rain and high waves to these regions, the NMC forecasted.

Authorities in Zhejiang province asked city governments to be fully prepared for the gales, downpours and floods brought by Dujuan.

The city governments were asked to tighten regulation over ships and move people away from areas that can be battered by Dujuan.

China Southern, the country's largest airline company, has planned to cancel 18 flights to or from Taipei City on Monday.

The NMC advised ships to return to harbor and local authorities to brace for floods and geological disasters. Residents are asked to stay indoors. The super typhoon will also disrupt construction.

China has a four-tier color-coded weather warning system, with red representing the most severe weather, followed by orange, yellow and blue.
