China issues yellow alert for thick fog

BEIJING, March 5 (Xinhua) -- CHINA's national observatory Tuesday issued a yellow alert for thick fog that will shroud parts of the country.

From Tuesday night to early Wednesday morning, thick fog will be seen in eastern and central provinces of Shandong, Henan, Anhui, Jiangsu and Hubei, according to the National Meteorological Center.

The visibility in parts of the areas will be reduced to less than 200 meters, the center said.

It suggests drivers in affected regions slow down, while airports, expressways and ports take appropriate safety measures.

CHINA has a three-tier color-coded warning system for fog, with red being the most serious, followed by orange and yellow.
