MetService is concerned that claims made by WeatherWatch this week on their website and in the media are misleading. The claims are about public access to weather information, particularly that related to public safety. In this blog, we refute those claims.
MetService’s newest 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.
The Northland flooding event, July 8th to 12th 2014
The average July monthly rainfall total at Kaikohe, Northland, is around 180mm. In just one week in July 2014 the rainfall recorded there totalled 477mm, and that wasn’t even the wettest part of the region.
The hectoPascal and Air Pressure In meteorology, the quantity pressure is an important driver of physical processes in the atmosphere. Pressure is the force applied over a unit of area, so it can be increased by having more force acting over a smaller area. Pressure is measured in Pascals, named after the French mathematician and physicist Blaise Pascal (who also devised the famous “Pascal’s triangle”). The abbreviation for Pascal is Pa. An example of where air has high pressure is the inside of an inflated tyre.
The Waikato may be our longest river, but the Clutha is swifter, has the largest catchment and carries the most water. With its headwaters in the rain-factory of the Southern Alps, the Clutha also produced, in 1878, one of New Zealand’s greatest floods.
A classical southerly buster looks likely to reach Wellington near to the evening rush hour today (Tuesday 25th March).

Cyclone Lusi retreating to open waters
Cyclone Lusi crossed the upper South Island overnight and is now pulling away across the open waters of the southern Pacific Ocean.
It was an unsettled start to 2014 with a persistent southwesterly bringing cooler than normal temperatures and a good scattering of showers. Frequent cries of “Where’s summer?” were heard up and down the country.
More active spring like weather spread in for New Year’s day with heavy rain and thunderstorms that affected the west coast of the South Island and a few spots further east.
New Zealanders can now check their phone to see when they need to protect their skin from the sun. The Health Promotion Agency (HPA) has worked with MetService and NIWA to produce a range of ways the sun protection information can be easily accessed by the public. In this mix is the inclusion of the Sun Protection Alert on MetService's Towns and Cities smartphone weather apps.
