The skies over northern New Zealand were mostly quiet last night despite a thunderstorm watch by MetService that included the risk of severe thunderstorms and tornadoes.
So, what is the different between a thunderstorm WATCH and a thunderstorm WARNING?
MetService has just introduced a new Severe Thunderstorm Warning Service.
It’s to help better track thunderstorms and give New Zealanders appropriate alerts to thunderstorms and potential tornadoes.
So while WeatherWatch.co.nz only believed there was a ‘slight risk’ for thunderstorms in Auckland in our forecast, we still needed to mention the severe weather watch from MetService – alerting the public that basically we have all the right ingredients for something a bit rougher…and judging by the lightning tracker yesterday evening I’m not surprised a watch was issued. There were well over 2000 strikes out to sea by yesterday afternoon.
Incidently, WeatherWatch believes there’s a higher risk for thunderstorms in Auckland from Saturday PM to Sunday AM.
You’ll find all the details on this new thunderstorm warning service here.

Do you expect any of the thunderstorms you believe will have a higher chance in Auckland in the Saturday PM to Sunday AM to be severe?

We’re unsure at this early stage if they’ll be severe – but I’ll point out that our weather data was picking thunderstorms for Saturday back on Monday. So the data is certainly pointing to unstable air.
Will have a better idea tomorrow when the system is closer.
