#Metservice have upgraded Rodney & Albany to a Severe Thunderstorm Warning as of 3:15pm today - we’re expecting torrential rain, which brings flash flooding risks.

Take shelter indoors if you can.
Stay away from trees.

Around 3:45 we’re expecting the storms to sit near OREWA, KAUKAPAKAPA, DAIRY FLAT, WHANGAPARAOA and SILVERDALE.

We’re expecting them to move southwards and lie over AUCKLAND, OREWA, ALBANY, DAIRY FLAT, WHANGAPARAOA, SILVERDALE, COATESVILLE and PAREMOREMO at 04:15 pm.

I made a movie showing #CycloneGabrielle moving down over #NZ for the three days Sunday to Tuesday 12-14 February 2023.

Thanks to #MetService for operating their #weather #radar network that makes this possible.

Can I just say a BIG thank-you to everyone at #MetService who has been working day and night to analyse and forecast and warn, and most importantly to communicate to the public and authorities about #CycloneGabrielle, starting days in advance.

No-one is saying "Why didn't they warn us about this?"

Midnight #MetService hand analysis of #CycloneGabrielle. Historic #storm. #weather #NZ

Will have been a sleepless night for many. Hope everyone is safe. Kia kaha.

Follow warnings at https://www.metservice.com/warnings/home . These were updated around 3 am this morning.

So I asked the #MetService if they would mirror the very useful content on their Twitter to #ActivityPub but .. “We currently don't have plans to distribute our information to more platforms” - a shame as Twitter’s reliability in question and weather alerts high on kiwi’s agenda right now. So bots it is.

Very windy at Channel Island right now from #CycloneGabrielle. SE 117 km/h gusting 146 km/h.

It shows an animation (animated GIF) of the last 24 hours of the #MetService #weather #radar composite over all of #NZ. If you allow it to use your location (this is not logged) it will put a red X on your approximate location on the map.

You can use this to look at the rain coming down over the country with #CycloneGabrielle.

This runs on my local server - best efforts - may not always be reliable. 🙂

The very latest #ECMWF model run (based on midday Saturday data) has the centre of the #CycloneGabrielle in a very dangerous location at 1 am Tuesday, as shown below - just north of #Auckland.

Those in the area, please, please continue to make preparations, and follow official #MetService warnings from https://www.metservice.com/warnings/home and information from authorities.

Stay safe.

These cyclones are horrible. We were in #Gisbourne for the last one. Might be worth a thought during the next few days of #CycloneGabrielle as to what official feeds we really need in the #ActivityPub #Mastodon world in #Aotearoa - I'm thinking #GeoNet, #MetService, #Niwa, #RadioNZ, personally I'd love to see Rivers each have their own alert level feed too ... and who else?

@billbennett #MetService #weather #warnings typically are updated more frequently if they *need* to be. In fact there was an update at 3 pm today. https://www.metservice.com/warnings/home

Useful blog post from #MetService about tropical cyclone tracks and the like. Highly relevant to ex TC #Hale of course.

My day revolves around being home by 6 pm so I can watch the weather forecast (not the news) that I already know (because #metservice). Everything else during the day is just a haze (not an exaggeration, my glasses are scratched. Surprised I can drive to be honest 😆).
