Your weather: Antarctic storm battering Australia has New Zealand in its sights
An Antarctic storm lashing southeast Australia with rain and snow will make its presence felt here tomorrow.
From early Friday morning the deepening low, currently over the Tasman Sea, will move on to the lower South Island, MetService meteorologist Andrew James said.
Rain will spread over western parts of the South Island first, while the storm's associated front will bring rain to west of the North Island, reaching Auckland in the afternoon/evening.
Over Saturday the rain will spread over the whole country.Advertisement Advertise with NZME.
