Here are the 3 main weather headlines for Sunday.

COOLER CHANGE HEADS NORTHWARDS
Temperatures are down in a number of places today due to more of a southerly flow ahead of high pressure rolling in. Temperatures look to rise again this coming week but tonight especially will be cooler in the lower South Island.

TROPICAL LOW (OR CYCLONE) TO BRUSH PAST NZ THIS WEEK
The next tropical storm is likely to develop near New Caledonia and brush past NZ this coming week. Most modelling shows the worst of the weather to be at sea, but it’s going to be close enough to definitely monitor.

At this stage it’s a serious storm that looks as though it will be steered just north of us due to high pressure centred over the southern part of NZ. With it being this close we’ll have daily updates about it.

Check your local WeatherWatch or RuralWeather forecast for more details on rain and wind potential this week where you are. Our IBM forecasts crunch the data from many trustworthy models to produce a single outlook for you.

HIGH PRESSURE DOMINATES MOST
High pressure will make most regions of NZ lean drier than normal this week. This map shows the next 7 days rainfall compared to what usually falls at this time of year.

The red shows drier, white normal rainfall and blue wetter than average.

The blue to the north is from the next tropical storm – this will move around a little over the coming days as modelling fine tunes the tracking of the tropical system.
