China renews yellow alert for thick fog

BEIJING -- China's national observatory on Saturday renewed a yellow alert for thick fog in some parts of the country.

From Saturday night to daytime of Sunday, heavy fog is expected to blanket the Bohai Strait, parts of the Bohai Sea and the Yellow Sea, as well as coastal waters of the Liaodong Peninsula, Shandong Peninsula and northern Jiangsu Province, according to the National Meteorological Center.

Visibility in some affected areas will be reduced to less than 1,000 meters, the center said.

Drivers are asked to maintain safe speeds, while airports, freeways and ports have been instructed to take appropriate safety measures.

Vessels sailing and operating have been advised to strengthen the lookout, control speed, and maintain a safe distance to ensure safe navigation.

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