As of 11 a.m., most parts of Taoyuan, Hsinchu, Miaoli, Taichung, Nantou, Changhua, down to Chiayi, Tainan, Kaohsiung and Pingtung were seeing good air quality whereas in the Taipei region and Changhua, more monitoring stations were showing yellow, indicating moderate air quality, than green (good air quality), according to the network (http://taqm.epa.gov.tw/taqm/en/).

In eastern Taiwan's Hualien and Taitung Counties and the offshore counties of Kinmen and Matsu, air quality was moderate.

For Saturday, central Taiwan and cities and counties to the south in western Taiwan could experience air quality that is unhealthy for sensitive groups, such as young children, the elderly and people with a chronic disease.
