The Milford Road (State Highway 94) is closed overnight due to an increasing risk of avalanche, but was expected to re-open by mid-morning tomorrow.
MetService has heavy rain warnings in place for Fiordland and the Otago headwaters, as well as other advisories further north in the South Island.
The forecaster says an active trough, preceded by a strong and moist northwest flow, will move over southern New Zealand tomorrow.

The front could also bring thunderstorms to parts of Southland and Otago, including Dunedin, tomorrow.
More settled conditions are expected in the South from Wednesday.
