An overnight snowfall continued on Friday in East China's Jiangxi province, disrupting air and expressway traffic.
Â
The provincial meteorological station issued an alert for icy roads on Friday morning.
Â
The provincial traffic department said all major expressways in the province are covered with ice.
Â
The Changbei International Airport said snow and ice are still being cleared from the airport's runway.
Â
The provincial meteorological station said the cold weather, which has driven temps down by 4 to 6 degrees Celsius, will likely last until Sunday.
Â
Public heating is not provided in Jiangxi, as its winter is usually mild and short. This year's cold snap has reminded locals of a period of severe weather encountered in 2008 that wreaked havoc and resulted in heavy economic losses.
