Taipei, May 20 (CNA) The Central Weather Bureau (CWB) issued an extremely rain warning for northern Taiwan on Monday, as a weather system arrived in the country, while the mercury was expected to dip sharply.

The extremely rain warning is effective for Taipei, New Taipei, Keelung, Taoyuan, Hsinchu and Miaoli, the CWB said, warning residents of the greater Taipei area, in particular, to stay alert to torrential downpours.

The CWB has issued a heavy rain warning for central and southern Taiwan, saying the rainfall will increase Monday afternoon as the weather front moves southward.

Only Lienchiang County in the outlying Matsu island was not included in the heavy rain warning, which is usually issued when accumulated rainfall of more than 80mm is expected over 24 hours or more than 40mm in one hour.

Extremely heavy rainfall is defined as more than 200mm in 24 hours or more than 100mm in three hours, according to the CWB warning system.

Daytime temperatures in northern Taiwan were expected fall Monday by about 10 degrees Celsius from the a day earlier to 24 degrees, while in central and southern Taiwan the mercury was forecast to remain at 30-31 degrees.

The weather front is likely to bring in strong winds to the northern half of Taiwan, Orchid Island, Green Island, the Hengchun Peninsula, and Penghu, Kinmen and Matsu islands, the CWB said.

By Tuesday, however, conditions across the country will begin to stabilize as the weather system moves away, and only sporadic showers are expected in the mountainous areas of central and southern Taiwan, the bureau said.

Meanwhile, the Environmental Protection Administration (EPA) said the air quality was good in central Taiwan, Yunlin, Chiayi, Tainan, Kaohsiung and Pingtung in the south, and Yilan, Hualien and Taitung in the east, and in Penghu.

Fair air quality was seen in some parts of northern Taiwan and Kinmen, according to the EPA's Air Quality Index (AQI).

The AQI was flashing an "orange alert" in Matsu, indicating unhealthy air for sensitive groups, due to a lack of wind in those areas to disperse atmospheric pollutants, the EPA said.
