Heavy rain warnings for parts of South Island

Heavy rain is moving up the West Coast of the South Island.

Metservice issued Heavy Rain Warnings for Fiordland north of Doubtful Sound, the headwaters of Otago's Lakes and Rivers and Westland District from Wednesday night.

Warnings come into force Thursday for the headwaters Canterbury's Lakes and Rivers about and south of Arthur's Pass, the ranges of Buller and Grey Districts and the ranges of the Tasman District northwest of Motueka.

Further heavy rain is expected Friday evening and Saturday in some areas.

Metservice said in Otago there may be high river levels or flooding beyond the warning area due to the lingering effects of the recent heavy rain.

It advises people to clear drains and gutters to prepare for heavy rain, avoid low-lying areas and drive cautiously.
