TAIPEI (Taiwan News) – The Central Weather Administration issued land warnings for Tropical Storm Danas at 8:30 p.m. Saturday, as airlines announced changes to their schedules for Sunday.

At 5 p.m., the storm was located 360 kilometers west-southwest of Eluanbi. It was moving at a speed of between 10 and 20 kph, heading north-northeast, turning to the northeast.

Maximum sustained winds near the center of the storm reached 23 meters per second, with gusts of up to 30 meters per second, the Central Weather Administration said.

Sea warnings for waters southwest of Taiwan have been in effect since Saturday morning. Forecasters warned of strong winds and heavy rain, especially on Sunday as the storm moved north over the Taiwan Strait. Danas was expected to reach the northern part of the strait west of Taipei on Monday before moving away from the country during the afternoon.

The land warnings were valid for Chiayi and Chiayi County, Tainan, Kaohsiung, Pingtung, and Penghu. An extremely heavy rain advisory was in force for Nantou, Yunlin, and Chiayi County from Saturday evening to Sunday morning, the Central Weather Administration said.

The approach of the storm had already made itself felt in the traffic situation on Saturday. Ferry connections between the main island and outlying islands were going to be suspended on Sunday, but worsening weather conditions led ferry operators to end service between Pingtung and Xiaoliuqiu Saturday afternoon, per CNA.

Airlines announced the cancellation of domestic flights for Sunday. However, Tigerair Taiwan said some of its international flights would be rescheduled, with flights leaving Taiwan early. The changes applied to flights between Kaohsiung and Okinawa and Tokyo, from Kaohsiung to Macau, and from Macau to Taichung, according to a CNA report.

Airlines cautioned travelers with flights booked for Sunday and Monday to keep a close watch on new developments and on the websites of airlines and airports.
