TAIPEI — Authorities in Taiwan are warning residents along its eastern coast to brace for the impacts Super Typhoon Kong-rey, which has rapidly intensified as it barrels towards the island after bashing the Philippines.

Kong-Rey, moving northwest over the Philippine Sea, reached super typhoon strength on Wednesday, according to the Joint Typhoon Warning Center (JTWC). With winds of 240 kph (150 mph), this storm is the equivalent of a Category 4 Atlantic hurricane.

The powerful typhoon is forecast to make landfall early Thursday (Wednesday evening ET) in Taitung, a sparsely populated county on Taiwan’s mountainous southeastern coast.

“As the typhoon continues to move towards the northwest, almost the whole of Taiwan will be covered by the storm circle later tonight,” meteorologist Chu Mei-lin, with the island’s weather agency, said in a press conference on Wednesday morning.

The Central Weather Administration (CWA) issued a sea warning Tuesday as the storm drew closer. On Wednesday, it also issued a land warning for two southern counties expected to be hit by the storm’s outer bands.

“We urge everyone to make preparations accordingly,” Chu warned.

Chu added that waves could reach up to eight meters high when the typhoon makes landfall. There will also be heavy rainfall across Taiwan on Thursday, including in Taipei.

Taiwan generally has a strong track record of responding to major typhoons though remote villages in more mountainous regions can be particularly vulnerable to landslides. Earlier this month, Typhoon Krathon, killed four people as it brought particularly heavy rains to the south of the island.

In recent days, northern parts of the Philippines’ main island of Luzon have been lashed by the outer bands of Kong-rey, known locally as Leon, as authorities order evacuations and warn of its impacts after already seeing devastation last week from Tropical Storm Tami, known as Kristine, which killed at least 130 people.

As of Wednesday morning, Kong-rey continues to skirt the island’s north as it moves away from the Philippines towards Taiwan.

Forecasts show the powerful storm could weaken slightly ahead of making a direct landfall on its southeastern coast, but it is still expected to unleash intense downpours, bringing flash flooding, storm surge and the risk of landslides.

Two outlying islands of Taiwan, Green Island and Orchid Island, suspended work and classes on Wednesday, according to the CWA.

More than 6,000 first responders have also been put on standby to assist in response to the typhoon, according to the Central Emergency Operations Center. Most flights and ferries across Taiwan are so far operating as usual, the center said on Wednesday. — CNN
