Before the post gets started could I say well done to all our posters on here especially MT who flagged this so far out, well done guys you know who you are.

Graces7 · 22-12-2015 2:23pm

Just seen this on met ie..we will weather it somehow.. We always do! My reaction was " OH GOD!"

RobertKK · 22-12-2015 2:26pm

I just hope it doesn't veer anymore southerly.

franer1970 · 22-12-2015 2:38pm

Has this system been officially declared a named storm yet? BBC TV guy this morning said it probably wouldn't get that honour.
Maybe they're raising the bar so as not to run out of names before the season is through :rolleyes:

ECM shows gusts close to 130 km/h at times but just on the exposed coast.

Anything stronger than that looks unlikely.

Graces7 · 22-12-2015 4:06pm

Worst gales I ever experienced were when I lived on an Outer Northern Orkney island. One was gusts of up to 124 MILES an hour and I was feeding my stock in that, clinging to washing poles. You felt as if the skin was being flayed off your face and the huge rocks that got thrown up on the shore... a neighbours hen house literally took off. Whenever there is a gale it reminds me. I dread them frankly but we manage..

Mars Bar · 22-12-2015 4:21pm

My sister is flying in to Knock tomorrow afternoon. Could be a hairy one for her!

green and yellow · 22-12-2015 4:34pm

just looking at next tuesday (29th) and windguru giving 153kph gusts for the Donegal. that sounds very very bad.
it was windguru i saw it on.

SNNUS · 22-12-2015 4:37pm

You did not see that on Windguru by any chance?

Early afternoon, before around 2:30pm I doubt there should be any problems. After that you never know.

12Z GFS shows a more southerly secondary depression following on early on Christmas Eve which would bring a second round of strong winds.

Larbre34 · 22-12-2015 5:17pm

Christmas Eva? High fives to the two Mets!

M.T. Cranium · 22-12-2015 5:17pm

Would say this is not trending towards a big event but would marginally verify the level 2 in the most exposed locations perhaps.

The reference to 29th -- the 06z GFS at 168h (about to be eclipsed by the 12z run) was showing an absolutely over-developed low west of the Mayo coast (moving north) with isobars so close together that they scream "cannot happen in nature" but for the record if the event did materialize just like that, gusts to 200 km/hr would be possible in exposed areas. I will edit in a comment on the 12z run when it goes past that time frame.

The models have been toying with major windstorm potential for days now, near the end of the month/year, spawned by what is more likely to verify, a very deep low in the west-central Atlantic that loops around between 30 and 20 W at some point taking aim at Iceland. The 06z GFS concept is a "secondary" that forms in the strong southerly gradient ahead of the same Atlantic low.

I sure hope it is wrong because the wind potential on the map is 1839-like for the west coast anyway.

(later edit) As noted by other posters in the meantime, the 12z GFS drops the worst of this and brings it in later, although it would be a level one sort of event for the 29th. Something to keep an eye on, for now the really severe potential is off the table rather than off the scale.

Better hope journalists dont read this. They will be recommending evacuation to the moon for the 29th! Potential is there to get very messy though :eek:

Meteorite58 · 22-12-2015 6:29pm

Very clear edge to the cold front as it passes over with a drop off on wind speeds for a time untill the second low comes into effect after a couple of hours for parts of the country although winds lighter and very fast moving system. Wonder will the initall cold front produce squall lines ?

It's already changed on the 12Z GFS. That potential really belongs in the FI thread because it's highly uncertain.

maquiladora · 22-12-2015 7:08pm

12Z ECM doesn't have that secondary low on Christmas Eve which the GFS had.

EURO4 doesn't have it either.

M.T. Cranium · 22-12-2015 7:17pm

So, I edited in a reality check on that earlier post ... thought it was worth a mention in case readers stumbled across it elsewhere without the qualifiers.

At the moment then it appears more like a minor ramping up of wind speeds on the 29th to easily-survived level one conditions.

To be Frank, I'm not sure if it gets a name or not.

Looking at the 5pm aviation forecast update, there's nothing to worry about (17knots Gusting 29kts between 1pm-3pm).

When the 11pm update is out, I will PM you and let you know of any changes.

maquiladora · 22-12-2015 10:51pm

18Z GFS again showing that second depression crossing the country early on Christmas Eve. Not buying it unless the other models show it.

JanuarySnowstor · 22-12-2015 10:59pm

Either way a serious amount of rain showing up on Christmas day.
Coinciding with high tides flooding looks possible

maquiladora · 23-12-2015 12:16am

Here's how that secondary depression on Christmas Eve looks at it enters the hi res NMM.

HIRLAM not buying it at all.

I think MT was speaking with a little bit of tongue in cheek with his comment as the next storm after Eva is Frank!

Strangegravy · 23-12-2015 9:57am

Ammmmmmm.... Ferry crossing from Holyhead at 2.30am Thurs morning. That's not looking good is it, is it likely to be cancelled do you think?

STORM EVA Strong winds Wednesday 23rd. Gusts possible up to 120km/h
