At least two people have been killed and hundreds of flights disrupted by torrential rain that has battered Taiwan since early Friday morning.
Northern and central Taiwan were hardest hit, with the storms bringing traffic in many areas to a standstill and unleashing some of the worst floods on the island in years.
The rain would continue until Monday and all residents on the island should remain on high alert, weather authorities said.
The Central Emergency Operation Centre said a woman motorcyclist and a man out for a walk were killed after they were swept away by floods in New Taipei City. An elderly woman was missing after a flash flood hit her farm in Keelung, northern Taiwan, on Friday, and five people were injured by debris brought down by the storm.
Ten counties in northern and central Taiwan recorded more than 600mm of rain by Saturday afternoon, officials said.
