TAIPEI — Under the influence of a stationary front, Taiwan will experience occasional showers or rain accompanied by thunder in the western part of Taiwan proper and Yilan County in the northeast Monday, the Central Weather Bureau (CWB) forecast.

Also, the Hualian and Taitung areas in the east will see occasional showers during the day, weathermen at the bureau said, reminding the public to carry umbrellas or raincoats when going out.

Thanks to the expected rain and cool breeze from the north on Monday, the daytime temperatures in Northern Taiwan, Yilan and Hualian will drop to 23-25 degrees Celsius, while Central and Southern Taiwan and Taitung in the east will see temperatures of 27-29 degrees, the CWB forecast.

Compared with the previous day, the mercury will drop by 3-5 degrees Celsius Monday, the weathermen said, describing daytime temperatures as “comfortable or slightly cold.”

The lows will drop to 19 23 degrees Celsius in the early morning hours and at night, the CWB said.

It also said that the outlying islands of Kinmen, Matsu and Phengu, as well as the northern area of Taiwan proper will see occasional fog or low clouds Monday. People planning road trips or flights should pay attention to possible weather changes, the CWB advised.

Meanwhile, air quality levels in all parts of Taiwan that day ranged from good to moderate based on the pollutant standards index (PSI) managed by the Environmental Protection Administration (EPA).

PSI refers the concentration of various pollutants in the air.

As for concentrations of fine particulate matter smaller than 2.5 micrometers (PM2.5), all areas around Taiwan saw low to medium levels of between 1 and 6, EPA data showed.

Under the EPA’s 10-tier PM2.5 index, pollution levels of 6 or lower are not considered hazardous for normal outdoor activities.
