The fourth and final full weekend of August is upon us and yet again we have a low pressure system in the forecast for northern New Zealand.

The low, which is expected to be the weakest of the four we’ve seen around northern New Zealand this month, may end up bringing more rain than previous stronger lows.  “A developing front is going to surge out of the Tasman Sea on Saturday then that will trigger a small scale low to develop on Sunday” says head weather analyst Philip Duncan.

“Saturday may be the sunnier, drier, day of the weekend but showers arrive in western and northern areas at night, turning to – you guessed it – rain at times on Sunday for northern areas once again”.

WeatherWatch.co.nz, like every other weekend this month, says wind direction from these northern lows is critical to where the rain will fall.  Other similar placed lows have teased some regions with rain while delivering torrential falls for others – this has been due to the geographical nature of the ranges in the north, such as the Coromandel, Kaimai and Gisborne ranges.

Once again the centre of this low will be very near Auckland.

The low on Sunday will be weak but showers and rain are expected for northern New Zealand.

Sunnier, drier, weather is likely in eastern New Zealand, particularly the South Island this weekend.
