1. If tornadoes are meant to be rare in NZ then why we are getting so many of these recently (in fact I have heard in the news at least once for almost every low recently). Also if a tornado is touching down anywhere in NZ, does it mean a ‘supercell’ storm has formed as it does in the USA?
2. It hasn’t been too cold recently. When can I next expect some very cold and wintry burst of weather?
3. What does temperature for each hour in the trends graph show, average, lowest or the exact temperature for that particular time e.g. 1:00pm? Same goes for the outlooks and 9-day forecasts.

Hi there.
1. Not every “tornado” quoted by the news is actually a tornado. Many are squall winds (or straight line winds) which create similar damage but aren’t actually a tornado. NZ’s news media is well known for misuing the term (even Wikipedia mentions it). NZ gets many EF0 and EF1 tornados – but most hit rural places so aren’t seen or documented.
2. Not sure yet – nothing on the horizon.
3. It’s what we expect the conditions to be at that time….if it says 17 degrees 1pm Thursday then that is what we are forecasting for that time.
Kind regards

Having reviewed Observations in my area for a few weeks now I am either in the middle of a lot of turbulence or some people do not know how to accurately report their observed wind directions. Do you have any process on how you choose which are authentic or just average out for your reporting? Is it worth your contacting all the observers on your contributing database and explaining that the wind direction stated is the direction it is coming from – not going to. i.e. A southerly wind is a wind that originates from the south and blows towards the north. In other words, it’s a wind coming from the south.

So how it works is that everyday people who have decent weather stations register them to a weather website so the data is shared with that site. Weather watch publishes that so we can see what is happening with the observed weather closer to our homes rather than just the main centres. If our wifi goes out or we have problems with the station then the data won’t upload or the station will be showing odd things. Weather watch can’t contact any of us and don’t control our stations, they’re just sharing our data which I assume they purchase from the website. The more people who have these weather stations that are shared the more data for weather watch to use and the easier it will be for other people to find a station that is in a microclimate that best reflects their own. Does that make sense?

Can you explain why the rain radar maps that the Met Service provide have such a bizarre colour scheme? It makes them very hard to read, and as a geographer it breaks my heart to see a system that has no logical progression from low to high in it. Other countries seem to use much more intuitive spectral scales.

Hi Phil, when the forecast for a particular location says x amount of rain today, and then x amount of rain tonight – between which hours is today, and between which is tonight? Hope that makes sense.

Hi Dylan, the ‘Today’ rainfall goes from 6am to 6pm, ‘Tonight’ covers 6pm to 6am. Rainfall totals update hourly, which means on the day itself those totals can shift around, especially if there are isolated heavy downpours around your region.
Under “Trends” in the WeatherWatch App, or at RuralWeather.co.nz you can also see rainfall in clearer visual/graph form, which helps work out general start, peak and end time of rain events. Along with forecast totals.
Hope that helps!
