As there are warnings already out, I thought it would be good to have a thread for the upcoming stormy period - with strong winds more likely than not for most of us, and potentially damaging winds thrown into the mix too. Winds will pick up during Thursday as an Atlantic low approaches, heralding the end of our settled period. Friday is when the damaging winds are likely, and beyond that low pressure won't be far away with the risk of further windy spells in the following couple of weeks.

To kick things off, a look at the winds for Friday. Note that I'm using mostly using MC charts as they are archived, rather than replaced with current ones each day.

MetO has the strongest winds affecting NI, northern England and southern Scotland. It's unusual for MetO to show this sort of strength at this range - there are widespread areas of 140-150km/h winds, which is the high 80s in MPH terms.

UKV is just a notch down, generally high 70s / low 80s instead, although there are the odd spots with high 80s:

The ICON "max gust" chart for Saturday morning shows the spread of the winds - as a reminder, the burgandy is 62 or higher, then each colour above that is about 6mph, meaning again there are widespread 70s and even 80s around:

Arpege is a tad lower generally, a tapestry of 60s and low 70s, but just look at the winds over the Republic - white is 200km/h, or 124mph.

And last but not least, GFS has swathes of 70s, with the odd 80:

I would expect an amber to be issued later today as a result - those winds will cause damage.

Hoping to avoid the severe wind gusts here, I remember the recent February  2022 event, lost 5 ridge tiles and 3 fence panels! That was a Friday also!

UKV has gusts topping 100mph around NW Wales on Friday. At 12z, there are gusts in the mid-90's widely around Liverpool Bay  the NW England coast.

Regarding IMBY, it does look like Kent missing the worst of the storm but can still expect a short spell of strong gales, although it is looking like a daytime event rather than in the middle of the night.

Storm Éowyn has now been named, and unusually that's without any amber warnings in force! The Met Office have expanded the yellow warning (which was on the amber track) and replaced the one over northern England/southern Scotland with another yellow, but a "high impact" yellow as they call it. That one's on the red track.

The text for the latter suggests they're taking the higher values from the UKV and MetO models seriously:

"a spell of very strong winds is likely, initially southeasterly before turning westerly, with peak gusts of 60-70 mph inland and 80-90 mph along some coasts and hills (perhaps even higher in a few locations). "

Wouldn't be surprised if the storm got downgraded nearer the time and ended up much weaker than expected as the models often overplay these storms and was the case last time we had a named storm and the warnings ended up being overly prudent.

One of the 18z GFS perturbations has wind gusts of 85mph for the SE next Thursday - including London.  That’s above Hurricane Force 12, which is truly worrying.

Hopefully it will be toned down

GFS has me down for peak gusts up to 82 knots, or about 94 mph. If this was the 70s, 80s or 90s, this would happen in a flash, but it isn't the 70s, 80s or 90s anymore, so I would expect the modern bog standard 'storm' gusts to be the usual 40kts to 60kts, if at all.

And the same model has Salthill, just outside of Galway City, having gust speeds of 85kts. or about 97mph.

I would say this looks pretty bad and unusual for Northern England and the NW in particular if it comes off.  Be interesting to see whether this is overdoing it. Worth bearing in mind Liverpool Airport only reported 60mph during the last amber warning when the Merseyside Derby was cancelled which was less than some forecasts.

Here's this morning's "max gust" chart for the ECM. Note the way the high winds "jump" west of Ireland, which is an artefact of the modelling only covering every 3 hours; in reality it'd be a smooth swathe of strong winds.

Other models such as UKV are broadly similar, and I would be surprised if we didn't have an amber for the UK (and the equivalent in Ireland) issued later this morning.
