Intensifying Typhoon Krathon forecast to hit Taiwan's populated west coast

Taiwan issued a land warning on Monday ahead of the arrival of Typhoon Krathon which is expected to intensify and cross the island's densely populated west coast bringing torrential rain and strong winds.

Taiwan regularly gets hit by typhoons but they generally land along the mountainous and sparsely populated east coast facing the Pacific.

Krathon, categorised as a medium strength typhoon, is forecast to hit the major port city of Kaohsiung early on Wednesday, then work its way across the bottom tip of Taiwan and cross out into the Pacific, the Central Weather Administration (CWA) said.

The typhoon is expected to further intensify into the equivalent of a Category 4 hurricane, packing powerful winds of more than 220 kmh (125 mph) near its centre, according to Tropical Storm Risk.

"The impact is getting bigger and bigger," said Gene Huang, forecaster at the CWA, pointing to threats to Taiwan's southwest and adding it was "rare" for such a powerful typhoon to make a direct hit to the island's western plains.

Huang warned residents there to be prepared for extreme winds of more than 150 kmh (93 mph).

Taiwan authorities said more than 1,000 rubber boats and 2,200 soldiers were on standby across Taiwan, including on the eastern coast where up to 1.3 metres (four feet) of rain was expected in the coming days.

Boats to Taiwan's outlying islands have already been cancelled and some domestic flights have been disrupted.

In July, Typhoon Gaemi killed at least 11 people in Taiwan.
