Here's the forecast evolution for low Zoey from the Met Office.


A tight enough gradient on the bent back occlusion for any time of the year across the NW of Ireland let alone June.

The GFS has a very similar solution.

Very similar although the cold front seems to be more active at 06 UTC.

So Low Zoey has been named storm Hector, the latest named storm on record; the previous latest storm of the season was storm Katie 25th to 28th March 2018.

It looks like this was yet another storm that was named by Met  Eireann. 


As far as as I can see the Met Office have only named three storms this season (A,C,& E) the other seven were named by the Irish, French and Americans.

Sorry, storm Katie was in 2016, of course, not 2018!

I was looking back at the records for the 14th of June to see just what other severe low's they've been since 1871 - the answer is very few - and none match the forecast severity of this one.


The nearest one that I could find was the 14th June 1908.

Here it is in a bit more detail from the 6 hour reanalysis data


Still no match for Hector née Zoey which looks like it will be unusually vigorous

Trausti Jonsson details some June stonkers near Iceland on his blog (in Icelandic) https://trj.blog.is/blog/trj/ 959.6 hPa in 1983!

Not a mention of 1908 but I suppose it didn't affect Iceland.
Icelandic is some language!

It's rare to see Cairngorm not on top of the highest gust table but the Bealach Na Ba topped it at 05 UTC

I presume the final column in the table is beaufort force.  I didn't know there was a F13 and F14.  Every day's a school day....

One needs to bear in mind that the Irish and UK met offices have only been naming storms for a few years, Still, there's no doubt that such an intense Low at this time of year is very unusual.

I don't know where I picked up the extended Beaufort scale from, but here's a graphic about it that I found in a quick Google search.

No doubt you already found something about it otherwise you'd be saying how wrong I got it.

I haven't looked.  I guessed you had found out about it somehwere and were using it because of that.  All I was saying was that I hadn't come across it before.
