Fung-wong is forecast to make landfall on Taiwan’s southwestern coast around the major port city of Kaohsiung on Wednesday, after powering through the Philippines as a much stronger system and killing six people.

It is then expected to cross the bottom part of Taiwan and enter the Pacific Ocean along the coast of the sparsely populated eastern counties of Taitung and Hualien.

Taiwan President Lai Ching-te, writing on his Facebook page, said people should not head into the mountains or go to the coast or other potentially dangerous areas.

In September, 18 people died in Hualien in flooding unleashed by an earlier typhoon.

The government has already ordered evacuations in the town of Guangfu, the scene of those deadly floods, and said a total of 3,337 people in four counties and cites had been moved to safer areas.

Hualien closed schools and offices today, as did the neighbouring county of Yilan.

The typhoon will not directly affect the northern city of Hsinchu, home to TSMC, the world’s largest contract chipmaker.
