Northlanders are in for the damp long haul as 61 hours of rain has been forecast for the region.
MetService issued a heavy rain watch for Northland with downpours predicted to start at 7pm tonight and last until 8am on Friday.
"There is a possibility of some areas within Northland receiving warning amounts
of rain over 18 to 24 hours within this period.
According to MetService, the wet weather is being driven by a sub-tropical weather system that recently caused flooding in New South Wales in Australia and is tracking towards New Zealand.
