On Sunday and Monday, classic Spring northwesterlies and rain are expected to affect central and southern parts of New Zealand.

“As is common in situations like this, heavy rain is very likely along the West Coast of the South Island on Sunday and Monday,” said MetService Chief Forecaster Peter Kreft. “But on these days there is also a good chance of significant rainfall in parts of Canterbury, Otago and Southland – which,in northwesterly situations, is not nearly as common.”

On Monday, northwesterlies will make their presence felt around central New Zealand, with gales expected from Hawkes Bay to Cook Strait.

A Severe Weather Watch has been issued for heavy rain and strong winds.
For the rain at least, this is likely to be upgraded to a Severe Weather Warning on the morning of Saturday 19 November.
