Heavy yellow dust blankets Korea
The National Meteorological Administration said the warning was in effect as of 7:00 p.m., as the heavy yellow dust storm, the strongest so far this year, has been spreading across the country.
The watchdog raised up its yellow dust alert level to a warning from an advisory later in the day as the density of the sandstorm got thicker.
"The yellow dust is blanketing the country and some parts of the country may see highly dense dust," an official at the weather agency said.
"As the sandstorm is expected to last until Monday, it is desirable to refrain from outdoor activities during the weekend."
The hazardous yellow dust usually sweeps South Korea in spring, caused by China's industrialization and deforestation.
The yellow storm carries doses of heavy metals, which can cause respiratory and health problems. [Yonhap]
