Southwest airflow's strong wind axis advancing; weather fan page: Rainfall to peak in the next 24 hours

Taiwan is currently under the influence of a strong southwest airflow and a stationary front, leading to highly unstable weather conditions and a peak in rainfall expected over the next 24 hours.

“

The southwest airflow's strong wind axis continues to advance; western and central Taiwan should strictly guard against severe rainfall.

Meteorological social media accounts, such as "Watching the Weather," report that a structured, linear mesoscale convective system, characteristic of a squall line, has developed south of the Taiwan Strait. This system is gradually organizing and moving towards southwestern Taiwan, driven by the southwest airflow.

The forecast indicates that the western and northeastern parts of the island, along with the mountains of eastern Taiwan, will experience localized heavy rainfall. Central and southern mountainous areas could see rainfall exceeding the heavy rain threshold. The strong convective system moving ashore is expected to bring strong gusts, lightning, and intense short-duration downpours, raising concerns about localized flooding in low-lying areas.

The system, originally scattered echoes in an arc shape, has gradually organized and transformed into a linear structure.

As the airflow moves inland and interacts with the Central Mountain Range, the terrain will enhance the uplift of moist air, intensifying the rainfall on the windward slopes. Residents in southwestern Taiwan are urged to remain vigilant and monitor the latest radar echoes and weather advisories due to the potential for severe weather. Mountainous regions are particularly at risk of landslides, rockfalls, and debris flows.

Under the effect of terrain-induced uplift, the heavy rainfall area will remain on the windward side.
