Tomorrow, a weak front will move northeast over the North Island while another moves northeast across the South Island, followed by a ridge of high pressure over the country on Wednesday.
MetService had moderate confidence Fiordland would reach warning criteria for rainfall accumulation, as well as low confidence of northwest winds rising to gale strength in exposed areas of Fiordland and Southland.
There was low confidence rain would reach warning criteria for Southern Westland.
"On Friday, the front should weaken as it moves onto the North Island, while a ridge of high pressure spreads over the South Island."
