Spring Showers Arrive: Taiwan’s Meteorological Agency Says Chance of Rain Increased After Tomb-Sweeping Day Holiday.

On April 4th, the day after the Qingming Festival, spring rain visited Taiwan. The cloud system in southern China moved eastward, bringing increased humidity, leading to a noticeable drop in temperatures in the central and northern regions. Following the Qingming Festival holiday, the influence of the cloud system and frontal boundaries increased the likelihood of widespread rainfall.

The Central Weather Bureau of Taiwan stated that today the cloud system in southern China moved eastward, resulting in a significant increase in humidity. There is a higher chance of rain in the northern and central regions, eastern areas, the Hengchun Peninsula, and southern mountainous regions with local brief showers expected. Other areas will experience mostly cloudy conditions.

In terms of temperatures, the Central Weather Bureau of Taiwan mentioned that the low temperatures in northern Taiwan, Yilan, and Hualien are around 16 to 17 degrees Celsius, while in the central and southern regions, as well as in Taitung, temperatures will range from 18 to 21 degrees. Daytime highs are expected to drop noticeably due to the rain, with temperatures around 20-21 degrees in the north and northeast, 23-24 degrees in the central and eastern regions, and maintaining between 27 to 29 degrees in the south.

The Central Weather Bureau of Taiwan warned that there is a chance of solid precipitation or scattered snowfall above 3,500 meters in the central to northern high mountains. People engaging in mountain activities should pay attention to weather changes and their own safety. Weather on the outlying islands is expected to turn into local brief showers, with temperatures around 19-23 degrees in Penghu, 17-22 degrees in Kinmen, and 15-19 degrees in Matsu. There is a probability of average winds reaching 6 on the Beaufort scale or gusts of 8 or above along the northern coast of Keelung and in certain areas of the Hengchun Peninsula.

According to the Ministry of Environmental Protection’s air quality forecast, on the 5th, the high-pressure circulation and the migration of the cloud system in southern China will result in an easterly wind environment. Poor dispersion conditions in the western part could lead to pollution accumulation. The ozone concentration is likely to increase in the afternoon due to photochemical reactions.

During the Qingming holiday, various traditional activities are taking place across the regions. Short-term pollutant concentrations are expected to rise, particularly in areas like Hsinchu, Miaoli, Yilan, Hualien, Taitung, Matsu, and Penghu, where the air quality is at a “moderate” level. The air quality level in the northern, central, Yunlin-Chiayi-Tainan-Pingtung areas, and Kinmen is categorized as “orange alert.”

The Central Weather Bureau of Taiwan stated that from the 7th to 9th, the cloud system in southern China will continue to move eastward with waves of humidity, leading to occasional showers in the northern and central regions, east, and southern mountains. From the 10th to 12th, a frontal system is expected to approach or affect the eastern regions, resulting in unstable weather conditions with a higher probability of showers, thunderstorms, and locally heavy rainfall. Rainfall patterns will not be continuous and will depend on the proximity and intensity of the frontal system.

Additionally, the Central Weather Bureau of Taiwan advised that on the 5th, the weather will change to rain and cooler temperatures. It is essential to pay attention to temperature changes, adjust clothing accordingly, and be prepared for cooler weather. From the 6th to the 10th, Matsu is likely to experience local fog or low clouds affecting visibility. Those traveling should be cautious and monitor flight and ferry information. Spring weather changes rapidly, so staying informed with the latest weather updates is crucial.
