Heavy rain for the West Coast of the South Island.

A large high lies across much of New Zealand from Sunday through to Tuesday, bringing settled weather to most areas. On Wednesday, a front is forecast to move onto the South Island, bringing heavy northerly rain. The heaviest falls are most likely in Fiordland and over southern and central parts of Westland, with moderate confidence of accumulations reaching warning amounts. Note, the heavy rain may continue over Westland into the latter part of next week, and forecasters will monitor this front over the coming days.
