Introduction
A heavy rain advisory has been activated for northern Taiwan as seasonal northeasterly winds continue to affect the region. The Central Weather Administration (CWA) issued the warning on Wednesday, signaling the likelihood of more than 80 millimeters of rainfall within 24 hours or 40 millimeters in three hours. Affected areas include Taipei, New Taipei, Keelung, and Yilan County. As the heavy rain persists, local authorities are urging residents to stay informed and take precautions.
Weather Forecast: Northeasterly Winds and Rainfall in Northern Taiwan
The ongoing seasonal northeasterly winds are intensifying rain showers, primarily impacting northern Taiwan. Areas like Taipei, New Taipei, Keelung, and Yilan are expected to experience continuous heavy rainfall. In addition, the CWA has warned of possible sudden downpours in mountainous regions surrounding Greater Taipei, as well as along Taiwan’s northeastern coast and in Yilan County.
Key Areas Affected:
| Area | Weather Condition | Rainfall Expected |
|---|---|---|
| Taipei | Heavy rain | Over 80mm in 24 hours |
| New Taipei | Heavy rain | Over 40mm in 3 hours |
| Keelung | Heavy rain | Over 80mm in 24 hours |
| Yilan County | Sudden downpours, heavy rain | 40-80mm in 24 hours |
Influence of Seasonal Winds and Moisture from China
The CWA indicated that the rainfall is not only due to the seasonal winds but also moisture moving in from southern China. This additional moisture has heightened the chances of sustained rainfall in northern Taiwan. In contrast, southern Taiwan will experience more stable weather with limited impact from the northeasterly winds.
Temperature Forecast: Cool in the North, Warm in the South
Along with the heavy rain, the temperature in northern Taiwan will remain relatively cool. The CWA has forecasted daytime highs ranging from 19°C to 22°C in Taipei and surrounding areas. Meanwhile, central and eastern Taiwan can expect temperatures to reach between 25°C and 26°C. Southern Taiwan will remain warmer, with highs likely to range from 27°C to 28°C.
Temperature Forecast Breakdown:
| Region | Daytime Temperature Forecast |
|---|---|
| Northern Taiwan | 19°C – 22°C |
| Central Taiwan | 25°C – 26°C |
| Southern Taiwan | 27°C – 28°C |
Additional Weather Warnings: Winds and Tropical Storm Man-Yi
In addition to the heavy rainfall, the CWA also warned of potential strong winds in areas including the Hengchun Peninsula, Orchid Island, Green Island, and the outlying islands of Kinmen, Matsu, and Penghu. Winds in these areas may intensify as the storm system continues its path.
Tropical Storm Man-Yi, which had been active over the past days, was downgraded to a tropical depression on Wednesday morning. As of 8 a.m., the storm was situated 1,200 kilometers west-southwest of Taiwan’s southernmost tip, Cape Eluanbi, and is expected to move in a west-southwest direction. The CWA does not anticipate a direct impact from this storm on Taiwan at this time.
Air Quality: Mostly Fair or Good Across Taiwan
Despite the rainfall, air quality in most parts of Taiwan is expected to be relatively good. The Ministry of Environment has reported that air quality will remain either “fair” or “good” for most regions across Taiwan, allowing residents to breathe easily.
