Taiwan shuttered offices, schools and tourist sites across the island Wednesday ahead of a powerful typhoon that already worsened seasonal rains in the Philippines, killed at least eight people and displaced 600,000.

Typhoon Gaemi's outer skirt was bringing heavy rain to much of Taiwan, where a direct landfall was expected Wednesday evening in the northern county of Ylan. Fishing boats were recalled to port amid turbulent seas, while air travelers were rushing to board overseas flights before the storm arrives, amid numerous cancellations.

On Wednesday morning, the typhoon was east of Taiwan moving at 13 kilometres per hour with maximum sustained wind speeds of 162 kilometres per hour, gusting at 198 kilometres per hour, the Central Weather Administration said. In the capital Taipei, heavy rain was falling, but high winds had not yet arrived.

Gaemi, which was called Carina in the Philippines, did not make landfall in the archipelago but enhanced its seasonal monsoon rains. The rains set off at least a dozen landslides and floods over five days that have caused eight deaths and displaced 600,000 people, including 35,000 who went to emergency shelters, the Philippines' disaster risk mitigation agency said.

In the densely populated region around the Philippine capital, government work and school classes were suspended after nonstop rains flooded many areas overnight, trapping cars in rising floodwater and stranding people in their homes. Residents who ventured out of their homes waded into knee- and waist-high floodwaters with some using improvised dinghies and paddling their way alongside cars, trucks and SUVs.

"I have instructed all concerned agencies to provide swift assistance to all those affected by Typhoon Carina and the enhanced southwest monsoon,” President Ferdinand Marcos Jr. said in a statement he posted on the X social media platform.

The Philippine coast guard said more than 350 passengers and cargo truck drivers and workers were stranded in seaports after ferries and cargo ships were prohibited from venturing into rough seas. It added that coast guard personnel helped more than 200 residents evacuate a coastal village in Batangas province south of Manila where storm-tossed waves have hit coastal houses.

The storm prompted the cancellation of air force drills off Taiwan's east coast and ferry services Tuesday.

Despite occasional flooding, Taiwan has substantially improved its resiliency through early warnings and preparations. The effects of the storm were expected to continue into Friday as it moved in a northwestern direction toward mainland China.
