Taipei, Feb. 20 (CNA) Partially sunny skies are expected around Taiwan on Wednesday as stable weather conditions continue, according to the Central Weather Bureau (CWB).
The CWB said temperatures Wednesday should be little changed from Tuesday, hitting 18-25 degrees Celsius in northern Taiwan, 19-29 degrees in central Taiwan and 23-29 degrees in the south.
Temperatures are expected to fall considerably at night, moving down to 17 degrees in northern Taiwan, 19 degrees in central Taiwan and 20 degrees in the south, the CWB forecast.
The bureau said little rain will be seen around Taiwan during the day, but sporadic showers are possible in mountainous areas around Taiwan, in particular in the afternoon.
The CWB also warned of possible foggy conditions in western Taiwan and on Kinmen and Matsu islands at night, undermining visibility.
The bureau, meanwhile, noted that a tropical depression located east-southeast of Guam was upgraded to a tropical storm early Wednesday morning.
The storm, named Wutip, was located about 4,170 kilometers east-southeast of Taiwan's southernmost tip as of 2 a.m. and was moving in a west-northwesterly direction, but it is still too far away to have an immediate effect on the country's weather, the CWB said.
Meanwhile, the air quality in parts of the country, such as northern Taiwan, Yilan, Hualien, Taitung and outlying Penghu, Matsu and Kinmen islands was expected to be good to fair on Wednesday, according to the Environmental Protection Agency (EPA).
But due to the lack of wind to disperse atmospheric pollutants, the Air Quality Index (AQI) was flashing an "orange alert" in central Taiwan, Yunlin, Chiayi, Tainan, Kaohsiung and Pingtung, indicating unhealthy levels of pollutants for sensitive groups, according to the EPA.
