SEOUL, April 1 (Yonhap) -- South Korea's weather officials issued a yellow dust alarm for most of the nation Sunday as the worst-of-the-year yellow dust hits South Korea.The yellow dust warning has been issued for most of the nation except for southern regions such as North and South Jeolla provinces and the southern island of Jeju, according to the Korea Meteorological Administration (KMA). In those less-affected areas, the KMA issued a dust advisory.Visibility in Seoul was only 3 kilometers as the heavy dust hit the capital city, compared with a more than 10-kilometer range in clear weather. In the southeastern port city of Busan, the range was 2 kilometers, while the range was only 1 kilometer in Ulsan."On Sunday, the heavy dust will hover over South Korea and the dust will start to clear up from Sunday night to Monday morning," a KMA official said.According to the weather agency, the dust originated from the Gobi desert in Mongolia and northern China and has advanced to South Korea as low atmospheric pressure moves eastward.It is the fourth time that the yellow dust warning has been issued in the capital city. The first warning was issued on March 21-22, 2002, while the latest one came on April 8-9, 2006.
