A late Autumn storm is going to produce heavy rain and heavy snow in the days ahead – but some will stay mostly dry.

The bulk of the rain in the days ahead will be on the West Coast with over 300mm possible by the weekend, on top of what has already fallen.

By late Thursday and across Friday this will turn as snow above 400m in the South Island and snow falls on Friday and Saturday over the North Island. All ski fields get snow by late week or the weekend.

Not everyone has rain though, as you can see in the first map below showing rainfall totals between now and midnight Saturday. The areas circled are mostly dry.
