BEIJING, Feb 7 (Reuters) - China issued dangerous heavy fog warnings for many regions and shipping was suspended in the Qiongzhou Strait, an important economic transport hub near Hainan, according to state and local media on Tuesday.
China has a four-tier, color-coded weather-warning system, with red representing the most severe warning, followed by orange, yellow and blue.
Multiple areas in China's southeastern Fujian also issued alerts for heavy fog, with ferry crossings between Xiamen and Zhangzhou suspended, according to CCTV.
Fog will continue in the mornings and evenings of Qiongzhou Strait until Friday, and conditions for navigation will be poor, CCTV reported citing the national weather forecast bureau.
In December, one person was killed when more than 200 vehicles were involved in a pile-up on a bridge in China's central Zhengzhou city due to heavy fog.
