South Korea: Dust storms forecast to affect most areas of the country between May 24-25

Event

Significant air pollution is forecast in most of South Korea May 24-25 as winds bring dust eastward from China and Mongolia. The Air Quality Integrated Forecast Center predicts that PM 10 air pollution (airborne particulate matter with a diameter of 10 microns or smaller - small enough to penetrate the lungs) will be at least 80-150, or "bad," in most of the country. PM 10 readings exceeding 150, or "very bad," are also possible. Meteorologists predict air quality will begin to improve from May 25.

Authorities could issue transport and industrial restrictions areas under very bad or bad warning levels. The government typically prohibits using large diesel trucks, reduces government vehicles' use, and limits operations at facilities that emit air pollutants, such as coal-fired power plants and construction sites.

Reduced visibility may cause transport disruptions. Flight delays are possible at airports in affected areas, including Incheon International Airport (ICN) and Gimpo International Airport (GMP) in Greater Seoul, especially during overnight and early morning hours when relative humidity is high. Traffic disruptions resulting from inadequate visibility are also possible on highways and secondary roads.

Advice

Observe local air quality index reports. Revisit contingency plans, including telecommuting options, in the event of significant air pollution. Confirm all transport reservations. Drive cautiously, and allow extra time to reach destinations due to low visibility and road congestion. Individuals with pre-existing respiratory conditions should carry adequate medication and consult with a physician prior to travel. Stay indoors in well-ventilated areas whenever possible, and seek medical attention if respiratory symptoms worsen. Eye irritation is possible; flush irritated eyes with copious amounts of clean water.
