Tomorrow's Weather / Typhoon Dolphin's Latest Path May Take a Sharp Turn! Marine Warning Timing Revealed — '4 Consecutive Days of Heavy Rain,' Full Week Forecast Here

Typhoon No. 13 'Dolphin' continues to strengthen! According to the Central Weather Administration, Typhoon Dolphin, currently a medium-strength storm, has a solid structure and slightly increased intensity, with a gale radius reaching 320 kilometers. It is now advancing toward the Ryukyu Islands. A marine typhoon warning is expected to be issued as early as the afternoon of Friday (7th), with Saturday to Sunday (8th–9th) marking the period when Dolphin will be closest to Taiwan and its impact most severe. Northern mountainous areas must remain especially vigilant against torrential downpours.

Dolphin to Approach Taiwan Closely Over the Weekend! Marine Warning Expected Friday; Land Warning to Be Assessed Based on Northward Turn Angle

According to the latest observations from the Central Weather Administration, Dolphin is currently located about 2,000 kilometers east of Taipei, moving west-northwest at 20 kilometers per hour. Huang En-hung, a CWB forecaster, analyzed that Dolphin is expected to reach the Ryukyu Islands by Friday and begin a northward turn over the weekend. Due to its extensive gale radius, which covers northern and northeastern sea areas, the CWB plans to issue a marine typhoon warning in the afternoon of Friday. Whether a land-based typhoon warning will follow depends on closely monitoring the angle and timing of its northward turn over the weekend.

The CWB added that Tropical Depression No. 15 west of the Philippines shows limited development and poses no threat to Taiwan. Although a tropical system is brewing east of Guam and may strengthen into Typhoon No. 14 'Kujira,' its great distance means no binary interaction (Fujiwhara effect) will occur between the two systems.

Rainfall and Path Analysis for the Coming Week: Heavy Rain in the North Over the Weekend, Southwest Winds Return Monday

As the typhoon's outer cloud bands approach, Taiwan's weather will undergo significant changes over the next week:

Wednesday to Thursday (5th–6th): Northerly winds prevail, with increasing moisture. Occasional brief showers in northern and northeastern regions; isolated morning rains in central and southern areas, with strong afternoon thunderstorms, especially in mountainous zones where localized heavy rain is possible. Central and southern regions should prepare for heavier rainfall from Thursday evening into Friday morning.

Friday (7th): As the typhoon's outer cloud system nears, brief showers will increase across western and northeastern Taiwan, while the east will remain partly cloudy to sunny.

Saturday to Sunday (8th–9th): Peak typhoon impact! Persistent showers in northern areas and central mountainous regions, with localized torrential rain possible in northern mountains. Brief showers also expected in central, southern regions, and mountainous areas nationwide.

Monday (10th): Dolphin gradually moves away, with environmental winds shifting to southwest. Western Taiwan will still see localized brief showers, with rainfall relatively increasing in central and southern regions.

Eastern Regions and Kinmen on Alert for Foehn-Induced Extreme Heat! Coastal Areas to Watch for Long Period Swells and Strong Gusts

Temperature-wise, highs across Taiwan will generally range from 33°C to 35°C through Saturday. Extreme heat is possible in Greater Taipei, mountainous areas near central and southern Taiwan, and parts of Hualien and Taitung. Due to subsidence from the typhoon's outer circulation, foehn winds are likely in eastern Taiwan from Thursday to Sunday (6th–9th). Kinmen must also remain alert for foehn-induced high temperatures on Saturday and Sunday (8th, 9th).

Marine conditions: Long period swells have already begun along the northern coast of Keelung, eastern Taiwan, and the Hengchun Peninsula. From Thursday, wave heights in northern and eastern seas will rise to 2–3 meters, potentially surging to 3–5 meters by Friday evening. Starting Saturday, long swells will also affect coastal areas north of central Taiwan, Matsu, and Penghu. The CWB strongly warns the public to avoid coastal sightseeing or marine activities during the typhoon's influence.
