Rain continues in western regions bringing a period of heavy rainfall reaching 30mm per hour in some areas. Northerly winds and wind gusts will be enhanced and possibly exceed 120 km/h before the passage, mainly in the ranges and exposed parts of the east/central NZ. Elsewhere just a bit blustery, nothing to stress about.

Due to the surge of cold air behind the front very isolated thunderstorms are expected in western coastal areas and also potentially Wellington in the North Island.

A heavy burst of snow is expected over the Southern Alps and surrounding hilly regions on Sunday night.
