Very cold southerlies are expected to spread north over New Zealand overnight Saturday and during Sunday, bringing a period of significant wintery weather to much of the country.
We can expect snow to relatively low levels, which is likely to close the Rimutaka Hill Road, and we'll be blasted by cold sleety/snowy showers.
Doesn't sound very pleasant at all! I think staying at home where it's warm & dry and maybe watching a few DVDs will be a great plan. If you are planning on heading out and over the Rimutaka Hill Rd, it would pay to check that it's actually open before you leave home.
