It also has the most extensive storm-force winds, going with a worst-case combo of the other models, so as well as Irish Sea coasts of Wales & NW England, it has similarly strong winds for the SW, which then travel all along the south coast, before bringing period of 70-80mph gusts all down the North Sea coasts of England and intensifying the gusts through the Straight of Calais.

I've a feeling it'll only go up from here, as both models have much higher winds only 40 miles away. And MetO still has 57, unusually still the highest of them all.

Incidentally re: Scilly, I'm not sure what's worse - the MetO raw for Bude, now forecasting 38 to 83 (and winds in the 80 for 6 hours), or 51 to 79 as is shown in the forecast for St Mary's. The reason being it's the delta between the background wind speed and the gusts which causes the damage, and a 45 mph delta (as per Bude) is much larger than the 28 mph one shown for St Mary's...

Neither would be fun to be around, mind you, and I suspect there will be widespread power cuts reported by Sunday morning.

Aiden McGivern from the Met Office has just confirmed in the latest forecast on YouTube that Storm Darragh was in fact officially named by the UK Met Office and so my earlier question has been answered.

As recently as yesterday, some of the models were going for that storm to be much further south and in some of the model output, that low was even only going to be affecting the south of England.

However, subsequent models runs have since brought that system back up north again and it now looks as we are all going to in its firing line as this low isn't now expected to start diving away to our south until it is in the process of moving across the UK from the west.

As with Storm Bert, there is also some snow in the mix for Scotland but unlike with Storm Bert which brought a lot of widespread snow which brought our buses to a standstill even here in Edinburgh, any snow from Storm Darragh is expected to be mainly confined to higher ground and to the north of the Central Belt although some of locations could still end up getting a fair amount of that.


The north of Edinburgh, usually always missing out on snow events which occur not just within the rest of Scotland or the UK, but also within the rest of Edinburgh.

Well Icon first out of the blocks with 80 to 100 knots gusts across a large =swath of England, later with 100 to 110 gusts along the south coast. Pembrokeshire getting into the 110 to 120 knot gust territory

Not what I was hoping for to be honest…. We live on the side of a long gentle slope looking out across the Hayle basin with the west Cornwall hills in the background. We do have the hills of Godolphin that give us some protection from the north and northeast but a northwest wind will blow straight into the front of the house. We don’t have any trees .. as they blew away decades ago.

We only have electric as power as well!

It's not looking very pleasant for you folks in the west - fingers crossed everyone's sensible and shores up wonky fence panels, takes down their trampolines etc. Definitely worth getting an LED lantern and some batteries if you're in the SW, Wales and Northern Ireland, I'd have thought!

I'd not be at all surprised to see red warnings issued tomorrow if the forecast holds as is. I can't recall seeing the Met Office App forecasting winds as high as this and also as widespread. Even in Eunice the top forecast gusts were lower as I recall.

We're planning a trip out to Llangollen on Sunday, and I might make a diversion on the way home via the Horseshoe. Hopefully see some snow on the tops (it's only the Clwydian Range, though) 😉

It wouldn't take much of a track change to bring areas east of say Reading back into the 60+ gust range though!

That's by far the worst on the models so far - widespread 70mph+ inland across the whole of Wales and the Southwest with 80mph+ extending a fair way inland especially in the Southwest

Whatever model drives the MetO raw (it's not UKV) is really ramping up the gust ratio down in the SW...

https://weather.metoffice.gov.uk/forecast/gbujj34bk#?date=2024-12-07&forecastChoice=weather 

28 to 81, then 30 to 83 - not far off a 3-to-1 ratio. You'd end up with the frankly daft scenario of sustained winds being well below gale level, but the gusts up to hurricane levels! 

I wonder why the ratio is so high in the SW? It's very unusual, normally 2-to-1 would be closer to the mark. Down here, for example, it's showing 26 to 47 on Saturday afternoon, peaking at 31 to 55 later on, 24 to 47 tonight, and 21 to 35 when the winds come in off the sea on Monday.

We’re between Pembrokeshire and Herefordshire, never seen such high gusts forecast for us at Poppit Sands - 86mph on Saturday morning. We’re in a very exposed location to N/NW winds. Really concerned about this one.

I would think localised Red warnings may be considered after data review in the morning. I’m thinking the NW Wales area and the N Somerset coast and possibly a more general Amber for the whole South including London and the NE coast on the exit region.

Think for me this is going to hit in a split instant. From near calm to fully on wild in seconds. Remember something like this in this happening back in Jan or Feb 2014.  It is in these sort of times that I miss my Davis anemometer to measure this sort of stuff.
