Taipei: Tropical Storm Peipah developed near Japan's Okinawa islands early Thursday, the Central Weather Administration (CWA) said, warning of possible disruptions to flights between Taiwan and Japan through Friday.

According to Focus Taiwan, Peipah, the 15th named storm of the 2025 Pacific typhoon season, was located 1,080 kilometers east-northeast of Taipei at 8 a.m. Thursday. It is moving north toward Kyushu, Japan, at 26 kph, with maximum sustained winds of 65 kph and gusts up to 90 kph.

The storm is forecast to track across Kyushu, Shikoku, and Honshu along the Pacific coast of western Japan on Thursday and Friday. The CWA advised travelers to check for possible changes to flight schedules.

Japan Airlines, in a 9:50 a.m. update, stated that no international flights were affected, although some domestic routes to islands south of Kyushu could face disruptions.

Meanwhile, Taiwan's weather is expected to be mostly sunny to partly cloudy, with isolated showers in the Hengchun Peninsula and Kinmen County, as reported by the CWA.

Daytime temperatures are forecast to range between 32-35 degrees Celsius across Taiwan and 27-32 degrees in the offshore islands of Penghu, Kinmen, and Matsu. Localized thunderstorms are likely in western Taiwan and eastern mountain areas in the afternoon, with heavy rain exceeding 40 millimeters per hour possible in western mountain regions and nearby areas in the south.

The CWA cautioned the public to remain alert for lightning, strong gusts, and flash floods often associated with afternoon thunderstorms.
