TAIPEI (CNA) – Snow has fallen again on Jade Mountain, Taiwan’s highest peak, thanks to moisture brought by a cold front that passed through the island in the early hours of Thursday, according to the Central Weather Bureau (CWB).

Snow fell on the upper reaches of Jade Mountain (Yushan) from 2:30 a.m. to 4:30 a.m., to a depth of one centimeter, CWB forecaster Lin Ding-yi (林定宜) said.

It is the third time this month that snow has fallen on the 3,952-meter mountain.

For the rest of Thursday after the front moved away from the country, areas north of Taichung in central Taiwan and northeastern parts of the island were expected to experience sunny or cloudy skies before another wave of northeasterly winds were forecast to approach later that night, Lin said.

From Friday to Saturday, the weather throughout Taiwan will become colder and drier, with the mercury ranging between 16-18 degrees Celsius, he forecast.

On Sunday, a new cold front will approach close to Taiwan, bringing scattered rain to the north, he said.

Meanwhile, as of 11 a.m., most monitoring stations in central and southern Taiwan flagged orange or red indicators, meaning that the air quality is either poor for sensitive groups or unhealthy for the general public, due to concentrations of PM2.5, according to the Taiwan Air Quality Monitoring Network under the Environmental Protection Administration (EPA).

The poor air quality in central and southern Taiwan was forecast to improve at around midnight, when a new wave of northeasterly winds will affect Taiwan.
