(CNA reporter Chang Hsiung-Feng, Taipei, 3rd) The Central Weather Administration announced that due to a frontal system, the South China cloud and rain band, and the Northeast Monsoon, showers or thunderstorms are expected across Taiwan tomorrow and on the 5th, with northern Taiwan needing to watch out for localized heavy rain. Another frontal system will affect the island on the 8th and 9th, and on Mother's Day (10th), the Northeast Monsoon will strengthen, causing a slight drop in high temperatures in northern Taiwan.
Forecaster Liu Pei-Teng of the Central Weather Administration told CNA reporters that as a frontal system approaches in the latter half of today, passes tomorrow, and the Northeast Monsoon strengthens, localized showers or thunderstorms are likely across Taiwan, with northern Taiwan possibly experiencing localized heavy rain. After the frontal system passes on the 5th, the South China cloud and rain band will move in and have an impact. Although the rain intensity will slightly decrease, there will still be scattered showers across Taiwan, and central and northern areas should still be wary of localized heavier rainfall.
Liu Pei-Teng stated that on the 6th and 7th, moisture will decrease, the Northeast Monsoon will weaken, and most areas will be cloudy to sunny, with localized brief showers in mountainous areas in the afternoon. On the 8th and 9th, another frontal system will pass and the Northeast Monsoon will slightly strengthen, bringing scattered showers to central and northern Taiwan and the eastern half, and afternoon thunderstorms to the south.
Liu Pei-Teng pointed out that on the 10th (Mother's Day), the Northeast Monsoon will strengthen, bringing localized brief showers to northern and eastern Taiwan and the Hengchun Peninsula, while other areas will be cloudy to sunny with localized brief showers in the afternoon.
Regarding temperatures, Liu Pei-Teng said that tomorrow during the day, due to rainfall and the Northeast Monsoon, high temperatures in northern Taiwan will drop to 22-25 degrees Celsius, while central and southern Taiwan will still have temperatures above 30 degrees. After nightfall, temperatures will drop further across Taiwan. The coolest period will be from tomorrow night to the early morning of the 5th, with low temperatures in northern Taiwan around 18-19 degrees, central Taiwan 20 degrees, and southern Taiwan around 23-24 degrees.
Liu Pei-Teng mentioned that on the 6th, the Northeast Monsoon will weaken, and temperatures will rise. High temperatures in northern Taiwan will be around 27-28 degrees, and central and southern Taiwan can reach above 30 degrees. On the 7th, high temperatures across Taiwan will all be above 30 degrees. On Mother's Day, due to the impact of the next wave of the Northeast Monsoon, high temperatures in northern Taiwan will slightly drop to 26-27 degrees, with low temperatures across Taiwan at night around 21-22 degrees.
In addition, Liu Pei-Teng reminded that from the evening of the 6th to the early morning of the 8th, the Matsu region is prone to low clouds or localized fog, affecting visibility. (Edited by Wu Su-Jou) 1150503
