Rain and strong wind is on the cards for most of the country, as well as snow in the South Island as a cold front is set to make its way across the country.
A number of road snowfall warnings have also been issued by MetService and will affect Arthur's Pass (SH73), Lindis Pass (SH8), Porters Pass (SH73), the Crown Range Rd, Milford Rd (SH94) and Haast Pass (SH6).

Strong wind watch
Aucklanders are waking up to a somewhat mixed day of weather to start the working week, with a few showers forecast this morning before turning to rain this evening and a temperature high of 16C.
But conditions are due to change overnight, as weather experts say a surge of gales will strike the North Island from tomorrow - particularly Auckland and Northland.
MetService has issued a strong wind watch for Northland, Auckland, Great Barrier Island and Coromandel Peninsula, north of Thames and Tairua.
"Southwest winds may approach severe gale in exposed places," the watch says.
The watch is in place from 3am to 4pm tomorrow.
WeatherWatch said a cold front is due to move in tomorrow and will bring a surge of gale-force winds gusting over 100km/h in exposed parts of the North Island.
The winds had the potential to be dangerous and damaging - and could result in power outages and tree branches being snapped off.
"The most exposed will be Northland and parts of Auckland, as the westerly ramps up then turns [southwest] - easing as a southerly by Tuesday night," a WeatherWatch spokesman said.
"Those that don't have gales are still likely to have a period of blustery conditions - but this event does look fairly short-lived.
"Worst of the winds will be hugging the western coastline of the North Island and spreading into northern areas during the day before easing at night."
MetService said rain is expected for the western South Island this afternoon, as the active front over the Tasman Sea pushes into New Zealand.
Rain is on the cards for eastern areas of the South Island and western parts of the North Island later this evening. That rain is due to spread further east overnight and into tomorrow morning.
