A cold front is forecast to move north across the country tomorrow, while a low develops to the east of the South Island and then moves away to the east late Tuesday.
A drop in temperatures, showers and snow was forecast over the South Island for tomorrow, and possibly across the lower and central North Island on Tuesday.
MetService said the cold snap was expected to affect many higher roads and farms in those areas, and there was a moderate risk the snow would reach warning criteria about inland Canterbury and Kaikōura from Monday evening.
According to Metservice, rain is expected to turn to snow tomorrow at several passes, including Lewis Pass (State Highway 7), Arthur's Pass (State Highway 73), Porters Pass (State Highway 73), Haast Pass (State Highway 6), Lindis Pass (State Highway 8).
Meanwhile, this evening snow is also expected to hit Crown Range Road, and the Milford Road (State Highway 94) tunnel.
A heavy snow watch was also in place north and south of the Rangitata River, North and Central Otago, and Dunedin.
