雪雾天气在河北徘徊 交通受影响菜价狂飙升

Shijiangzhuang (CNS) -- Heavy fog and snowstorms triggered by a cold front have lingered in Hebei Province since last Thursday, disrupting traffic and delaying flights.

The local meteorological center has issued three orange alerts for heavy fog, four warnings for icy ground and two blue alerts for a cold wave until Saturday.

Parts of six highways have been closed off and 36 flights have been affected at Shijiazhuang Zhengding International Airport.

Vegetables prices in the province have also spiked, as the bad weather continues to threaten supply lines and the health of crops. Some green leafy vegetables are up by more than 50 percent.
