Mercury plunges, with occasional rain in northern Taiwan

The mercury dropped in northern and northeastern Taiwan overnight as expected, with 20 degrees Celsius measured in Yilan County early Sunday, the lowest recorded in the county since the beginning of autumn this year, the Central Weather Bureau (CWB) said.

Temperatures in Suao in Yilan County and Tamsui in New Taipei were also detected at 20.4 degrees and 20.8 degrees, respectively, in the early morning as powerful northeasterly winds struck.

"From today to the upcoming week, it will continue to be wet and cool in the north and northeast," said CWB forecaster Lin Ting-yi (???), adding that this was a typical autumn weather pattern.

Daytime temperatures will be 23-25 degrees C. in those areas, with the lows to hit 20-21 degrees accompanied by occasional showers, Lin predicted.

In the upcoming week, people in the central and southern areas could still expect a partly cloudy sky, with the daytime highs to reach around 30 degrees. However, there is a chance for occasional showers in the afternoon, Lin said.

According to the CWB forecast, under the influence of the northeasterly winds, Taiwan's northern and northeastern areas will receive occasional downpours on Sunday, while residents in the central and southern areas will see cloudy weather with poor air quality.

Rain will fall in the north and northeast, with sporadic downpours and heavy rain in the mountainous areas of Yilan, Hualien, the northern coast of Keelung and greater Taipei, the bureau said.

Meanwhile, according to data from the air quality monitoring system operated by the Environmental Protection Administration (EPA), the concentration of fine particulate matter smaller than 2.5 micrometers (PM2.5) will be high in the central and southern regions on Sunday, with some areas expected to receive an extremely high PM2.5 concentration.

According to the EPA, level-10 PM2.5 concentrations exceed 71 micrograms per cubic meter and are considered extremely high, but measurements above level 7 are deemed severe enough to cause tangible discomfort and health problems.

Given the air quality, the elderly and those with chronic lung or heart diseases should avoid prolonged or strenuous outdoor physical activities, the EPA advised.
