Some regions such as Hunan province saw fog reduce visibility to 50 meters

After dense fog caused travel disruptions in central and southern regions at the weekend, sleet and strong wind will arrive and continue to affect these regions until Thursday, the national weather authority said on Sunday.

Starting on Monday, northern regions, including part of the Inner Mongolia autonomous region, will experience heavy snow, while sleet and rain will cover the majority of central and southern regions, the China Meteorological Observatory said.

Strong winds and a drop in temperature will follow, it added.

The wind will disperse the dense fog that has shrouded the central and southern regions, including parts of Hebei, Henan, Hubei and Anhui provinces, since Saturday.

The fog reduced visibility to 500 meters, closing expressways and causing many accidents, the observatory said.

During the travel rush, which will end on Feb 21, an estimated 2.98 billion trips will be made, according to the National Development and Reform Commission.

Since Thursday, the country has seen passenger flow soar after the weeklong Lunar New Year holiday ended, while the lingering fog and imminent
