Computer models are holding fast and true in the main as it continues to track a sizeable snow storm due to hit parts of New Zealand tomorrow.

There is potential for some record breaking snowfalls over the next few days in pockets of the country and it appears that waves of snow activity will sweep up southern and eastern parts.

” The start of the coldest air still seems to be arriving tomorrow and perhaps a little earlier than we thought during the day” according to Weather Analyst Richard Green. ” It seems to be coming in waves, with the first band moving through later tomorrow and overnight before a possible easing for a part of Monday in the south. Now for some people they might think there’s not much snow but a heavier surge should arrive later on Monday and Monday night ” says Richard Green.

Indications are for places such as Canterbury that snow could be around 20cm deep in Christchurch, possibly up to  30-40 cm during the whole event and heavier falls on the Port Hills and further inland.

“it’s difficult to give exact figures on how much snow will fall and where it will take place as there’s always a risk that these things don’t come off. We think it’s best to advise everyone as it has the potential to be quite significant so it’s always good to be prepared,” Richard Green says.

WeatherWatch believes that the wintry weather in exposed areas of the storm is likely to last up to 3-4days but cold temperatures could linger for considerably longer.
