Here in Edinburgh, we're within the amber warning area albeit in the northern part of it.

I can see a wild and very noisy period coming up with that which I'm not really looking forward to, although we will at least get to experience some interesting weather which will be a big change from the ongoing borefest which we've been experiencing just now apart from the fact that we at least had a frost this morning.

Severe sea state forecast ecm along that Irish coast, 14 metres very high 8 second per wave nasty wind shear and unpredictable swell forecast at this time with violent storm about 150 miles from coast very severe indeed.

I agree that Meteireann is a bit trigger happy on warnings. I hope you're right about the storm not being so bad but the problem is that we just can't be sure yet. The head of the National Emergency Coordination Group(I didn't know that we had one of those)is on the RTE website saying that this will be one of the severest storms ever. If you're right, it's going to take credibility out of future warnings.

I'm sure that given the severity of these warnings across Ireland, Met Eireann would no doubt have probably named this storm anyway had the Met Office not already done so but given that they did so before any amber warnings were even issued here in the UK, I can see that they probably just wanted to raise their awareness of that as quickly as they could.

As this is the first named storm of 2025, you might also be aware of the fact that it will have been exactly 10 years ago this year since this storm naming system was first introduced with that initially starting off as a UK/Ireland partnership, and with the Dutch joining in later on.

It's hard to believe that this all started so long ago and this just goes to show how quickly time seems to pass.

GFS looks nasty for the south on Monday, something we need to watch out for. Hopefully this little daughter low will swing further south or not develop at all

 the dreaded quick rise and fall in temperatures that we saw down here back in '87, too... I remember reading up afterwards how temperatures were in the teens at midnight (back when that was unusual) before dropping sharply as the cold front came through.

We had no power for over a week from that storm, I wouldn't wish the likes on anyone.

 Of course, at the time I was really excited by the whole thing and having 2 days off school and power cuts were fun when you're a kid! And of course damage to the house is something your parents deal with

The sound of tiles sliding off and smashing, the constant roar, the completely pitch black view outside, the (wooden-framed) room shaking with every gust... it was vile. I was 8, and have never been more scared in my life. It sowed a deep dislike of strong winds that persists to this day, I usually get antsy during gales and a couple of times a year I'll have a dream where my house gets destroyed in strong winds, I wake up just as it all collapses in on me. I guess these days we'd call it mild PTSD!

Anyway, back to the modelling - there's little change this morning, and the ARPEGE produces even stronger winds - note the area of >240km/h winds west of Ireland, that's 149mph.

I note the MetO raw now has four hours of winds in the mid to high 90s for Galway, peaking at 99mph. As the system moves eastwards the winds ease somewhat but last night's MetO chart that I posted is still much the same this morning, widespread 80s over northern England/southern Scotland.

Hopefully the wider public will take the warnings seriously up there, this is no normal winter gale.

I was curious so looked up the Wxcharts.com version of the Arpege chart. It turns out that Friday's low peaks at a whopping 158mph over the Atlantic. Sustained winds peak at 122mph, the equivalent of a middling Cat 3 hurricane.

The follow-on low for Sunday into Monday peaks at 109mph, 81mph sustained, the equivalent of a Cat 1 hurricane:

These are seriously strong winds, and I can't recall seeing two such strong extratropical storms like that in close succession before. That deep cold over North America moving over record-warm mid-Atlantic water is really our worst enemy when it comes to winter weather!

Interesting Estofex forecast for tomorrow..

We'll see, I guess, but it's tomorrow where I expect to hear reports of wild weather (given the strength of the jet, the intensity of that low etc).

As others have mentioned a couple of days ago, Monday's low also looks interesting. Yesterday we saw how the 12z MetO and 15z UKV both had a small area of 110mph winds from it in the Channel, with the other models also showing varying degrees of strong winds close to or over the south and SE. This morning's MetO high-res isn't available yet, but I'll be interested to see what it does today.

On the subject of forecasts, the  storm has now come into the range of the shipping forecast. Shannon looks like experiencing very severe conditions. I would not like to be off parts of the west coast of Ireland tomorrow morning.

GALE WARNING

Westerly gale force 8 increasing severe gale force 9 soon, then hurricane force 12 later

WIND

West backing south, 7 to severe gale 9, becoming cyclonic storm 10 to hurricane 12 later.

SEA STATE

Very rough, becoming very high or phenomenal later.

WEATHER

Rain or squally showers.

VISIBILITY

Good, occasionally poor.

As you would expect there's still a bit of variation in terms of track and intensity of tomorrow's low. MetO has it a fair bit north of yesterday's output (and I would expect the UKV to follow), whereas ECM keeps the track as it was, but increases the winds. It has a max of 140mph just west of Ireland, with the west coasts there seeing 110mph winds. There are then some 80s and 90s for Northern Ireland to follow.

Further north and east, 70s look more likely, with the odd spot seeing 80s, although the T+42 chart shows 113mph winds east of Aberdeen - clearly the topography is having a moderating effect on the winds as the swathe crosses the British Isles.

Just an observation, but the UK Met have gust speeds here currently of about 34 knots, while the ECMWF have mean speeds of 18 knots for this moment in time.  There is barely a puff of wind outside. And looking at the two nearest met stations to me, mean speeds are ranging between 5 and 8 knots.

Here it's much the same, but once winds are forecast to hit 25 or so mph it starts to match what's forecast. I suspect it's something to do with the night-time boundary layer but I'm unsure of the exact mechanics.

Hope you're all prepped for the storm to come, and that you get through it without any damage.

Looks interesting at Loop Head lighthouse in County Clare, too. Highest lowland gust I can find at 112mph - highest lowland gust I can ever remember seeing on the Meto generated forecasts. It's dropped off a bit from 115mph this morning. Has anyone found higher?

First red warning from METO for Northern Ireland:

For 7 AM to 2 PM - looks like they're taking those raw charts showing 100+ pretty seriously.

Perhaps there'll be another red issued for southern Scotland/northern England a bit later on.

I am likely being overly cynical, but I can't help but think that this storm will be a lot tamer than what is currently shown on the maps, at least for my specific location. No doubt the west coast itself will have a wild ride though, as will inland areas that have some atitude behind them.

This just goes from bad to worse here as Edinburgh is in the red warning zone, so I'm really not looking forward to that at all.😡

I guess that this probably serves me right for moaning about the weather being boring and uninteresting here for most of the time, even on occasions when the weather is more interesting elsewhere.
