Taipei-Air quality is expected to be poor across most of Taiwan Wednesday, due to northeasterly winds bringing particulate pollution from China, according to the Environmental Protection Agency (EPA).
As of 11 a.m. Wednesday, 24 air quality monitoring stations in northern Taiwan flashed red warnings, indicating unhealthy air for the general public, and the pollution is expected to spread to central and southern Taiwan in the afternoon, the EPA said.
In eastern Taiwan, air quality was rated as good or fair, the monitoring data showed.
The pollution will likely disperse in northern Taiwan overnight, but could linger in central and southern areas until Friday, said the EPA.
The Air Quality Index (AQI) is likely to flash an orange alert, meaning unhealthy air for sensitive groups, in central and southern Taiwan Thursday, and southern Taiwan Friday, the EPA said.
Prevailing northeasterly winds are also expected to cause continuous rain in eastern and northeastern Taiwan, with a chance of sporadic rainfall in northern and southeastern Taiwan, according to the Central Weather Bureau (CWB).
The bureau issued a heavy rain advisory for Yilan Wednesday morning.
Central and southern Taiwan will continue to see cloudy to sunny skies on Wednesday, with a chance of afternoon showers in mountainous areas, said the CWB.
Daytime highs on Wednesday are forecast to reach 24-26 degrees in the north and the east, and 28-30 degrees in central and southern Taiwan.
Lows of 21-23 degrees can be expected at nighttime across the country, and the CWB warned of major day-night temperature differences in central and southern Taiwan.
Meanwhile, a tropical depression in the South China Sea was upgraded to Tropical Storm Matmo early Wednesday morning, but is not expected to directly impact Taiwan, according to CWB projections.
