Various flood risks for North Island today forecasters warn flood waters could affect a number of roads and farms over the coming 24 hours as a very slow moving sub-tropical low descends onto the country.

The rain bands, which almost entirely affect the North Island, have set in today with heavy falls expected to become more frequent this afternoon and overnight. says rain will be heavy enough to cause some flooding.  “We’ll have surface flooding, low lying flooding and the possibility of even flash flooding” says head weather analyst Philip Duncan.

Mr Duncan says the rain warnings are what he describes as moderate rainfall amounts which are enough to cause some flooding across highways, farms and low lying places.  “It will be an extra slow journey home today and tomorrow morning for holidaymakers” he says.

Surface flooding is most likely on flat highways while flash flooding is related to localised heavy downpours from isolated thunderstorms or down-bursts.  Flash flooding is less common but can be the most dangerous. advises people to stay out of streams and rivers over the next 48 hours.

Larger river flooding may also occur in low lying areas after prolonged heavy rain over the next 24 to 48 hours up in the ranges.

While serious flooding isn’t yet expected from this low advises those in low lying and vulnerable areas to be aware of the incoming heavy rain and to keep up with the latest rain warnings.
