TAIPEI (Taiwan News) — Typhoon Jangmi is expected to pass closest to Taiwan between Sunday night and Monday, bringing increased moisture and brief showers to northern and northeastern parts of the country, according to the Central Weather Administration.

Forecaster Lin Ting-yi (林定宜) said Jangmi strengthened into a typhoon Sunday morning and is currently maintaining the minimum intensity required for typhoon classification. Slight additional strengthening is possible, he said, per CNA.

Lin said moisture from the typhoon’s outer circulation will bring localized, brief showers to windward areas in northern and northeastern Taiwan on Monday. Other parts of Taiwan are expected to see mostly cloudy to sunny skies, with localized afternoon thunderstorms in mountainous areas.

Temperatures across Taiwan are expected to remain hot early this week, with highs ranging from 28 to 32 C in northern and eastern Taiwan and 33 to 35 C in central and southern regions. Residents in Tainan should be alert for localized temperatures exceeding 36 C, Lin said.

According to the CWA, Typhoon Jangmi will gradually move away on Tuesday. Most areas are forecast to experience partly cloudy to sunny weather, with localized afternoon thunderstorms in mountainous regions.

On Wednesday, winds are expected to shift to a southerly direction, bringing scattered brief showers to southern coastal areas in the early morning and localized afternoon thunderstorms in Taipei, northeastern Taiwan, and mountainous areas elsewhere.

Lin said the southwest monsoon is expected to strengthen beginning Thursday, bringing increased moisture and more unstable weather conditions across Taiwan.

Southern Taiwan is forecast to experience localized brief showers or thunderstorms, while central and northern Taiwan, northeastern Taiwan, and mountainous areas are expected to see localized afternoon thunderstorms, per CNA.

From Thursday onward, southern and southeastern Taiwan are expected to experience more frequent rain showers and thunderstorms, while other regions will remain mostly cloudy with localized afternoon thunderstorms. The CWA warned that all areas could experience periods of heavy rainfall.

Forecasts indicate the southwest monsoon could persist through mid-June, bringing the potential for significant rainfall across Taiwan.

Lin also warned that long-period waves are possible through Wednesday along the northern coast of Keelung, eastern Taiwan, the Hengchun Peninsula, and the coast of Matsu.
