Mercury forecast to rise Tuesday as wind system weakens

TAIPEI (CNA) – The temperature is forecast to rise during the daytime Tuesday with the northeast monsoon weakening, according to the Central Weather Bureau (CWB).

The CWB said daytime highs are expected to rise by 1-2 degrees Celsius from a day earlier on Tuesday with the mercury forecast to range from 24-25 degrees in northern Taiwan, 26-27 degrees in central areas and 29-30 degrees in the south.

However, another wave of the northeast monsoon is expected to arrive Tuesday night and the CWB urged the public to remain alert over the day to night temperature differential.

According to the CWB, night temperatures are forecast to fall to 18-21 degrees across Taiwan late Tuesday, while the monsoon is expected to bring rain to northern areas, in particular, the greater Taipei area, and people are advised to take an umbrella if they go outdoors.

The lowest temperature in low-lying parts of Taiwan early Tuesday morning was recorded at 18.7 degrees at the CWB’s Chiayi monitoring station, according to the bureau.

With the new monsoon set to arrive Tuesday night, strong winds are expected in areas from Tainan northward and in eastern Taiwan, including Orchid Island and Green Island, as well as the Hengchun Peninsula, and outlying islands such as Kinmen and Matsu.

The influence of the monsoon is expected to continue Wednesday with daytime temperatures forecast to fall to 18-19 degrees in northern Taiwan, and 25-28 degrees in central and southern parts of the country, the CWB said.

On Wednesday night temperatures are expected to fall to 15 degrees in northern Taiwan and 16-18 degrees in central and southern areas, the CWB said.

Meanwhile, the air quality in parts of the country, such as northern Taiwan, Yilan, Hualien, Taitung, the islands of Kinmen, Matsu and Penghu, central Taiwan, Yunlin, Chiayi and Tainan, is expected to be good to fair on Tuesday according to the Environmental Protection Administration (EPA).

However, with a lack of wind to disperse atmospheric pollutants, the Air Quality Index (AQI) is flashing an “orange alert” in Kaohsiung and Pingtung, indicating unhealthy levels for sensitive groups, according to the EPA.
