Wu Der-rong: Northern, Northeastern Regions to Turn Rainy This Afternoon, Wider Rainfall Tomorrow
Meteorological expert Wu Der-rong predicts that a front will pass over Taiwan from this afternoon to tomorrow, bringing localized brief rainfall to the northern and northeastern regions. The scope of rainfall will expand tomorrow, with more significant precipitation in the northern and eastern parts. Additionally, Typhoon Sinlaku poses no threat to Taiwan or Japan.

TAIPEI — Meteorological expert Wu Der-rong said that a front will pass over Taiwan from this afternoon to tomorrow, bringing localized brief rainfall to the northern and northeastern regions this afternoon, and a wider range of rainfall tomorrow, with more significant precipitation in the northern and eastern parts. In addition, Typhoon Sinlaku poses no threat to Taiwan or Japan.
Wu Der-rong, an adjunct associate professor at the Department of Atmospheric Sciences, National Central University, stated today in the "Xie Tian Ji Jiao Shi" column of the Meteorological Applications Promotion Foundation that according to the latest data from the Central Weather Administration at 2 AM today, the 4th moderate typhoon Sinlaku is located north of Guam and will make a "large turn" northeastward towards the south of Japan. The environmental "westerly wind shear" is gradually destroying its structure and continuously weakening it, posing no threat to Taiwan or Japan.
Wu Der-rong said that the latest European Centre for Medium-Range Weather Forecasts (ECMWF) model shows that a weak front will pass over Taiwan from this afternoon to tomorrow, with localized brief rainfall possible in the northern and northeastern regions this afternoon, and a slightly wider range of rainfall tomorrow, with more significant precipitation in the northern and eastern parts.
He mentioned that it will still be warm during the day today, with temperatures expected to be 21 to 30 degrees Celsius in the north, 20 to 32 degrees in the central region, 20 to 34 degrees in the south, and 20 to 34 degrees in the east. Tomorrow, northern Taiwan will turn slightly cooler, while the south will remain warm.
Wu Der-rong said that the latest model simulation shows that from April 19 to 21, under the influence of dry air after the front, the weather will turn clear and stable across Taiwan, with warm days and large diurnal temperature differences. There may be occasional scattered showers in Hualien and Taitung. He said that on April 22, moisture around Taiwan will increase, and the atmosphere will become unstable. It will still be mostly cloudy to sunny, with localized afternoon showers in mountainous areas and eastern Taiwan.
Wu Der-rong stated that the latest model simulation has been adjusted to show that on April 23, a front will approach, bringing localized showers or thunderstorms to areas north of central Taiwan. On April 24 and 25, a stronger front than the previous one will affect Taiwan. On April 24, there will be localized showers or thunderstorms north of central Taiwan, and on April 25, the rainfall area will gradually move southward. On April 26, the front will move southward to the Bashi Channel, and the weather will improve. Various international models are still being adjusted at the end of the period, and continued observation is needed. (Editor: Huang Ming-hsi) 1150417
