BEIJING, March 22 (Reuters) - Capital Beijing and several provinces in China will be affected by thick, dense sandstorms that will severely affect visibility, Chinese weather authorities said on Wednesday.
The Central Meteorological Observatory issued yellow warning signals from Wednesday to early morning Thursday for Shaanxi, Shanxi, Hebei, Heilongjiang, Jilin, Liaoning, Shandong, Henan, Jiangsu, Anhui and Hubei provinces.
Many areas will have low visibility, weather forecasters said, cautioning drivers on speed.
China has a four-tier, colour-coded weather-warning system, with red representing the most severe warning, followed by orange, yellow and blue.
Beijing, which was also issued a yellow sandstorm warning, has experienced sand and dust storms over the past several days, causing pollution levels to drastically increase.
