MetService’s long-range weather radar, situated near Kaeo in Northland, officially commenced operations on Monday 28 July 2014, with early imagery from the radar enabling MetService forecasters to provide very valuable information to Civil Defence and the public ahead of the June storms experienced in the region that year.

If you look back to the Towns & Cities forecast tabs or the Rural forecasts, you will notice that at the bottom of the 10 day forecasts is this phrase: “Forecasts and temperatures for days 1-5 are produced by MetService meteorologists. Forecasts and temperatures for days 6-10 are automatically generated by MetService's computer weather modelling system.”
New Zealand is great for outdoor sports. Sometimes the weather is too. With summer approaching and long weekends on the calendar, the time is ripe for packing cars and heading off into the great outdoors. But how do you know if the weather is going to be any good when you’re planning a trip, particularly to places ‘off the beaten track’? This blog post is about how you can get a better idea of the weather in areas not covered by regular forecasts - the types of areas frequented by rock climbers, mountain bikers, kayakers etc.
Sitting out in the middle of the ocean, New Zealand is vulnerable to extremes of weather from all directions; from the remains of tropical systems barrelling in from the north, to cold winter southerlies bringing a blanket of snow.
As New Zealand’s designated national meteorological service to the World Meteorological Organisation (WMO), it is MetService's responsibility to provide clear, concise and timely warnings of severe weather that is likely to affect New Zealand.

We remember our war dead on Anzac Day, 25th April, the anniversary of the landings at Gallipoli in World War I. But our heaviest losses in that war occurred on the Western Front. Our worst day was 12 October 1917 – the First Battle of Passchendaele. New Zealand lost 1,000 soldiers in two hours because the high command ignored the effect of heavy rain on the battlefield. The Ypres Salient, in Belgium, where the campaign took place was low lying. Prior to the war the water table was 35 centimetres below the surface.
