Issued by MetService at 10:32am Saturday 23-Sep-2017

Heavy rain for the Otago Headwaters, and northwest gales for much of southern and central New Zealand from Sunday to Tuesday.

A very strong and moist northwest flow spreads onto New Zealand during Sunday, which persists until at least Tuesday. An embedded front will bring a burst of heavy rain to western areas as it moves slowly northwards from Sunday evening, and a Heavy Rain Warning has been issued for Fiordland and Westland south of Hokitika. A period of northwest gales are also forecast for much of southern and central New Zealand ahead of this front, and a Strong Wind Warning has been issued for Canterbury.

People are advised to keep up to date with forecasts as parts of this Watch will likely be upgraded to a Warning in Sunday morning's issue, and additional regions will be placed on Watch.
