Heavy rain over northern parts of both islands developing Monday
An active low over the north Tasman Sea is expected to move southwards during Sunday to lie west of the North Island by midnight and become slow moving west of the upper South Island by midday Monday. The low will spread a moist northeast flow over New Zealand during Sunday and Monday, bringing rain to many northern and central areas of New Zealand. A period of significant heavy rain is expected during Monday and into Tuesday in northern and eastern Northland, the Coromandel Peninsula, Nelson, Marlborough and areas of the Canterbury High Country and foothills. 100mm to 150mm of rain could accumulate in most of these areas. However in the ranges of Nelson 150 to 250mm is possible.
People are advised that these rainfalls can cause rivers and streams to rise rapidly, surface fllooding, slips and make driving conditions hazardous.

Heavy rainfall warnings have been issued for parts of Northland, the Coromandel Peninsula, Nelson, Marlborough, Kaikoura Coast and Canterbury for Monday and continuing into Tuesday.
In addition further heavy rain is expected in parts of the north and east of both islands from Wednesday through to Thursday.

could hear the seagulls this morning...they must have seen GFS, LOL
but you do have to say that with a northerly fetch reaching further and further into the tropics and a low that is slowly deepening, big potential for rain

Looks like 30-40mm for the whole event for ChCh to me. only 2mm so far
Much more for the inland/highcountry areras.
Time will tell

You could well be right, starting to feed back in now, and all that to the north over the nelson area and beyond is set to feed down i think.... time will tell as you say.
