It's a weather mash up, with a mix of a rain, snow, strong winds, cold and warm temperatures, thanks to a strong northwesterly followed by a southerly.
There are heavy rain warnings Tuesday night for the South Island's West Coast, Tasman and Nelson Lakes, and headwaters of the Canterbury lakes and rivers.
There are also road snow warnings for the alpine passes as well as the Crown Range.
