TAIPEI - One person was missing and 131 were injured after a weekend of storms unleashed by back-to-back Typhoon Nesat and Tropical Storm Haitang, reported Taiwan media on Monday (July 31).

Rescuers were looking for a man missing after a motorbike accident near a flooded area in the southernmost Pingtung county where accumulated rainfall had topped 663.5 mm as of 8 am, Central News Agency reported, citing information released by the Central Emergency Operation Centre.

As of 1pm on Monday, Taipei accounted for 54 of the injured, followed by the north-eastern country of Yilan with 52, the central city of Taichung with 11, and 10 in the northern Taoyuan City, the semi-official news agency said.

Meanwhile more than 5,00 people in Kaohsiung had been evacuated as of Monday morning as Tropical Storm Haitang brought heavy rainfall to Taiwan's second-largest city.

Nearly 400 millimeters of rain had fallen in the city's mountainanous areas over the past 24 hours, increasing risks of mudslides and forcing the evacuation of many residents, Central News Agency said.

Townships in coastal areas and Hengchun Penisula in southern Taiwan have seen the worst damage, it said, with an entire road washed away in the resort town of Kenting.

In addition, Nesat and Haitang caused flooding in 279 locations. In 77 the flood water has since subsided, though 202 remain flooded, according to the centre.

In addition, the storms resulted in power cuts to 667,046 households. As of 1 m on Monday, power had been restored to 646,459, with 20,587 households still subject to power outages, the centre said.

About 300 people were evacuated as a precaution while several roads were closed and bus services suspended due to mudslides, Central News Agency reported, citing the local government.
