I think this came about from the well worded Metservice facebook post on Monday.

It was more likely based on the earlier Press Release below, which was also posted on MS's website news page (although that doesn't appear to be working atm).Razor wrote:I think this came about from the well worded Metservice facebook post on Monday.
''Bomb' Low brings Wind, Rain & Cold' - Scoop
Unfortuantely it doesn't fully explain what that 'bomb' criteria is, nor does the referred 2012 blog…

Re: Possible "Bomb" cyclogenesis - Jan 18-20
Why bother with the term 'bomb'. The system was not untypical apart from the time of year i guess.
As for hurricane force gusts, its impossible to get such a thing but the media have got worse over the years.

The last true 'bomb' low to affect NZ was around March 3, 2012, so fairly 'untypical' I'd have thought…

Re: Possible "Bomb" cyclogenesis - Jan 18-20
We just drove from Kurow to Waikouaiti and there was signs of significant winds at various points. The wind around Duntroon were very very strong - luckily I was running with it at my back so it helped a lot!Orion wrote:Report here:Manukau heads obs wrote:WSW gales developing in coastal otago now

Then towards Oamaru a lot of tree and branches down, likewise towards Hampden/Moeraki areas, which makes sense with the 130km/hr quoted from the ODT. Wind at home is not that strong at all at the moment, and my weather station maxed out at 70km/hr at 9:42 am. My station doesn't record wind well, so actual gusts would have been higher than that, but that's the 2nd highest I've recorded in the 14months that we've been back here.

Re: Possible "Bomb" cyclogenesis - Jan 18-20
I agree with you on this. It is safe to put out a general warning for all areas in an area where high winds are forecasted. Here, there wasn't much wind, well, the ENE persisted well into the afternoon then the occasional north or NW came through and at times it was calm. The real influence of the NW was from about 6am this morning until the SW came through around 2pm, with similar wind strengths.Manukau heads obs wrote:but you know as well as I do that NWers in the canterbury plains are a fickle thing
sometimes the wind pressure works to create wind other times the pressure release is somewhere else (e.g banks peninsular or futher inland in the gorges etc)...its just how it all works out...not easy to predict

Re: Possible "Bomb" cyclogenesis - Jan 18-20
looks like alot of damage (flooding/slips) in the Westport area etc and wind damage in Otago (and southern NI)
when watching the news..all spots that had warnings in place
not your typical summer weather pattern (more typical of August)

Yes, more so.
Not so much "Climate Change" but "Seasonal change" with seasons running into each other, it seems to be?

It will be related to climate change

I agree with Brian that this current pattern could be climate change.

Sorry but not on topic, I have noticed this not working.Nev wrote: which was also posted on MS's website news page (although that doesn't appear to be working atm).
Maybe it's a scheme to get you to subscribe to their emails.
