The forecaster has issued road snowfall warnings for the Lindis Pass (State Highway 8), the Crown Range Road, the Milford Road (SH94) and Arthur's Pass (SH73).
A front was expected to move northeast across the country from the southwest today, followed by a strong cold southerly change, MetService said.
