There's already a MerEireann red warning for South West Ireland for Friday and an orange warning for the rest of RoI. I have a feeling that our Met hands out warnings a little more easily than yours, though.

Winds peak according to the ECMWF at around 117mph; this is oversea. But corresponds to a mid Catogary 3 hurricane level on safir simpson, though I should enphasise that this is not a hurricane, just a hurricane force extratropical cyclone.

In terms of strongest sustained winds over actual land, ECM has it at 72mph over parts of SW Ireland which is near Hurricane force, and at which time the storm itself has maximum winds of 101mph (or cat 2 equivalent).

Based on this I think its basically certain that SW ireland will see Beaufort9 'severe storm' force winds, and a coin toss somewhere could be in the Beafort10 'Hurricane' force winds catogary. Obviously this means I would expect the maximum gust recorded to be even higher and probably approaching 150mph. Its quite likely this will be a record breaker of sorts for somewhere.

This is forecast to hit NW England and N Wales at morning rush hour on Friday. Winds gusting to 90mph or higher close to coasts (Isle of Man has a 99mph figure right over it at 9am, per Met Office model) With so many cars on the roads, it increases the risk of deaths and major incidents. The only small saving grace is that a fair number of people work from home on Fridays.

True. Storm force winds are sustained (10 min mean) winds of between 55mph and 63mph. Rare enough these days even on the exposed western headlands of Ireland and Scotland.

This morning's Arpege, incidentally, paints a grim picture for the north, but even more so for Ireland: the worst of the winds will be in the Galway area by the looks of it, and yes, that's showing over 110mph gusts. That grey area further SW, over the ocean, is upwards of 137mph, which is just plain nuts. Life-threatening conditions, frankly, and I only hope it's overdoing things.

I recall sometime in the mid 2000s when I was driving back from college to Salthill, where I lived at the time, while there was a wind storm raging and the seas of Galway Bay had a colour I had never seen before. A sort of dirty looking orange brown. That to me was scarier than the wind itself. It was like this waving beast just wanted to reclaim the land back and was ready for war.

Not sure how to pronounce the name 'Éowyn'? It looks like and Irish name but I've never come across it before. Could be Scots or Welsh Gealic as well. I'm just pronouce it 'Owen'.

And the Irish Met Office says, "pronounced Ay-oh-win". I'm guessing it's not an Irish name then as it's pronounced like an Englishman reading French. If it were Irish I daresay it'd sound completely different (memories of the Siobhan and Niamh discussion from another thread...)

So now we know. 😁

It's worth saying that those values the models are suggesting are off the scale compared to what you would normally see there, on a par if not stronger(!) than what we had here in 1987. Were that to happen here I would expect prolonged power cuts, many trees down and significant structural damage... I don't know whether you have your own house or not, but if you do I'd be checking up on the buildings insurance just in case!

FWIW, the Met Office has automated forecasts for Galway... and they're showing winds well into the 90s! It's accompanied with 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.

https://weather.metoffice.gov.uk/forecast/gc3x1g6dq#?date=2025-01-24 

EDIT: Those gust ratios are insane btw, 26 to 93? That's even more than the 3-to-1 ratios we saw down in the Westcountry in one of the storms last year.
