Low pressure that today has formed in the Tasman Sea is expected to grow into a large system by the weekend bringing torrential rain, gales and possibly heavy snow.
Heavy rain is likely across northern and western parts of both islands while strong to gale north easterlies spread over a number of regions.
However as the low moves eastward the winds may turn to bitterly cold south easterlies – possibly bringing heavy snow in to Canterbury and the Southern Alps on Monday or Tuesday.
The Weather Watch Centre will be closely monitoring the low and we’ll have a more extensive forecast tomorrow morning.

I was looking forward to some heavy snow but now it looks like it has dissapard.Do you know when this will happen

Unfortunately for you none of the computer models or data seem to point towards snow in Canterbury anymore. It’s still a number of days out but we’d rate the chances of snow in Canterbury, to low levels, as "low to very low" based on what we’re looking at right now. Sorry!

Is this going to be a monster?

A this stage size wise it will be large but aggressive wise probably moderate. Has the potential to be severe so that’s why we’re watching it so closely.

Looking at the models, it looks like BOP region could well be the worst place to be.. Very heavy rain from Sunday.. Centre of the low looks to be about 980, which is pretty intense..
