South Island

A heavy rain warning has been issued for Westland, Buller, the headwaters of the Canterbury lakes and rivers about and south of Arthur's Pass, the Otago lakes and rivers and Fiordland. 

The forecaster warns these areas could see heavy rain, which may cause streams and rivers to rise rapidly, surface flooding and slips are also possible, while driving conditions may be hazardous. 

Canterbury lakes and rivers about and south of Arthur's Pass will see the worst of the weather with up to 220mm of rain expected and the chance of thunderstorms.

A strong wind warning is in place for the Canterbury Plains, Christchurch and Banks Peninsula, the Canterbury High Country, Fiordland, Southland, Stewart Island and Otago.

MetService said the strong wind gusts could damage trees, powerlines and unsecured structures while driving may be hazardous, especially for high-sided vehicles and motorcycles.

All the regions under the strong wind gusts are expected to see gale-force winds in excess of 120km/h, with the Canterbury High Country to see the worst of the wind with damaging gusts of 140 to 160km/h in exposed places.
