MetService meteorologist Andy Best said the first cold front will move up the South Island today bringing heavy rain and strong winds for much of the island.
The rain has already started to make an impact on the West Coast. As much as 110mm may fall in the Buller ranges and north of Westport through until 11pm today.

Another front will move onto the South Island on Wednesday morning, bringing much colder weather in its wake, "as the freezing levels lower dramatically, bringing a distinct wintry feel to conditions over the far south of the country", Mr Best said.
Snow is expected to settle at around 400 metres over Southland, Fiordland and Otago.
"The maximum temperature in Dunedin on Wednesday is expected to be only 9C and just 8C in Invercargill. Temperatures overnight Wednesday/Thursday are expected to fall to 0C in Christchurch and Blenheim, around 2 or 3C in the northern Wellington suburbs and down to 0C at Masterton as the cold air pushes farther north," Mr Best said.
It's expected the weather will improve over much of the country by Thursday although cold southerlies will continue to affect temperatures in the South Island.
