BEIJING: China's national observatory on Monday issued a yellow alert for Beijing sandstorms in the northern part of the country. Beijing was engulfed by the largest sandstorms in a decade on Monday morning, which originated in Mongolia, causing the visibility in most areas to be less than 1,000 meters and bringing the PM10 close to 10,000 micrograms per cubic meter in the city center. Starting from Monday to 8 a.m. Tuesday, affected by cold fronts and heavy winds, floating sand and dust are expected to sweep parts of Xinjiang, Inner Mongolia, Heilongjiang, Jilin, Liaoning, Gansu, Ningxia, Shaanxi, Shanxi, Hebei, Beijing and Tianjin, Xinhua news agency quoted the National Meteorological Center as saying in a forecast. Some regions in Inner Mongolia, Ningxia, Shaanxi and Shanxi will be hit by strong sandstorms, the center said. It has advised the public to take precautions against the heavy winds and sandstorms and suggested that drivers prepare for poor visibility. China has a four-tier colour-coded weather warning system for sandstorms with red representing the most severe, followed by orange, yellow, and blue. The Central Meteorological Observatory called it the most intense sand-dust weather process in China in the past decade, and the range of sand-dust storms was also the widest in the past 10 years.
