China’s Weather Center Maintains Yellow Fog Alert Across 10+ Regions

What changed

China’s National Meteorological Center continued a yellow fog alert at 06:00 on November 13, covering parts of more than 10 provinces and regions. Dense fog was forecast from morning into late morning across areas including Beijing, Tianjin, Hebei, Heilongjiang, Liaoning, Jiangsu, Anhui, Chongqing, Guizhou, Yunnan and Guangxi.

In parts of southeastern Beijing, western Tianjin, eastern and central Hebei, western Heilongjiang and central Guizhou, visibility could fall below 200 metres.

Why it matters

This is a transport warning as much as a weather bulletin. Drivers are being told to slow down, while airports, expressways and ferry terminals are expected to take measures to protect traffic. A visibility reading below 200 metres can turn an ordinary morning journey into a stop-start operation, particularly across the Beijing-Tianjin-Hebei area.

The alert covers a wide but uneven stretch of the country, from the northeast to central and southwestern regions. That makes local conditions important: one city may see only dense fog, while a nearby area faces the much sharper constraint of visibility below 200 metres.

The actual duration, disruption and post-alert visibility readings were not yet confirmed. For now, the practical question is whether transport authorities need to keep restrictions in place after the morning window ends.
