Road Warnings As Cold Weather LingersState highways remain open as a polar blast moves up the South Island, but warnings are in place for travel on several highways. After heavy rain brought flooding on the West Coast yesterday, snow and rain is affecting other areas today. State Highway 94/Milford Road reopened this morning after an overnight closure because of the snow risk. Care is being urged on this highway as more snow is possible today and heavy machinery will be operating on the road. Road users are encouraged to check the latest weather reports, and the status of the state highways at NZTA’s Journey Planner site, before setting out for their travel.
