Weather: 3 Typhoons and 1 Low-Pressure System in Succession! Heavy Rain to Strike from 'This Day' as Weather Across Taiwan Becomes Extremely Unstable

Marine alerts have been officially lifted, but people should still take precautions against rain-related disruptions. As Typhoon Dolphin gradually moves away from Taiwan's landmass, the Central Weather Administration officially lifted the marine typhoon warning late last night. Wu Derong, adjunct associate professor at the Department of Atmospheric Sciences at National Central University, analyzed in the 'Leak the Heavens Classroom' column of the Meteorological Application and Promotion Foundation that although the typhoon threat has diminished, the atmospheric environment is shifting under the influence of southwest winds, and windward areas should remain vigilant against localized heavy rainfall.

Meteorological teams indicate that the overall weather pattern will undergo a two-stage transformation. In the coming week, in addition to monitoring dramatic weather changes, the public should stay updated with real-time weather bulletins when traveling to specific regions.

Where will heavy rain occur as southwest winds arrive? Southwest Taiwan braces for downpours; southeast Taiwan watches for heatwaves

Wu Derong explained that from today through the 12th, wind patterns around Taiwan will shift entirely to southwest flow. As a result, localized showers and thunderstorms are expected in the windward southwest regions, potentially leading to significant accumulated rainfall. Other broad areas will remain generally clear and hot during daytime, with southeastern Taiwan particularly prone to extreme high temperatures due to wind direction and topography.

With atmospheric instability driven by thermal effects, in addition to windward rainfall, central and northern Taiwan also have favorable conditions for afternoon thunderstorms. People are advised to carry rain gear when going out in the afternoon.

When will moisture from the South China Sea decrease? Strong convection may bring a prolonged rainy period starting from the 13th

Regarding medium- to long-term forecasts, Wu Derong further warns that from the 13th to the 19th, although southwest winds may gradually weaken, moisture transport from the South China Sea will continue. During this period, brief morning showers may still occur in southwestern Taiwan.

As the overall atmosphere remains unstable, strong convection is highly likely to develop in western Taiwan during afternoon hours, potentially leading to a prolonged rainy phase. Afternoon thunderstorms during this period may be intense, requiring close attention to short-term weather updates and official special bulletins from the Central Weather Administration.

Multiple tropical systems coexisting over the ocean? Typhoon Chan-hom expected to strike Japan in the coming days

In addition to weather changes over Taiwan, oceanic systems remain highly active. Wu Derong observes that there are currently three tropical storms and one tropical depression in the northwestern Pacific, all developing around a broad 'monsoon depression.' Typhoon Dolphin (No. 13) is currently near southern China, moving northwestward and gradually weakening and dissipating.

Typhoon Chan-hom (No. 15) is forecast to move northwestward, then shift westward into the northern flank of the monsoon depression, and is expected to strike Japan's main island between the 11th and 12th. Travelers planning trips to Japan should monitor flight schedules closely. Meanwhile, Typhoon Peipah (No. 16) is located along the southern edge of the monsoon depression, being guided by westerly winds to move northeastward and away. The tropical depression east of Peipah is moving northward but currently shows no significant development trend.
