Heavy fog has caused traffic and flight delays in cities across China, state media reported January 15.
In Changsha City, central Hunan province, fog caused traffic delays on several highways and limited visibility to under 50 meters (54.6 yards) on Thursday morning, state broadcaster CCTV said.
CCTV showed footage of slow-moving traffic shrouded in fog.
Quoting local authorities, CCTV reported that several highways in Tianjin municipality of northern China were also affected on Thursday morning.
On January 14, over 10,000 travelers were stranded at Urumqi International Airport in north-western Xinjiang Autonomous Region after many flights were delayed due to the fog.
One stranded passenger, surnamed Huang, told CCTV that his flight was canceled.
“Originally I was going to fly out to Yining, but due to the massive fog in Urumqi, I've been waiting here for about two or three hours. As of now the flight has been canceled. Only here can I change my reservation,” said Huang.
China's National Meteorological Center issued smog and fog alerts on Thursday morning but also said they were expected to ease from Friday from the north to the south across the country.
