Looking at the latest GFS there appears to be no let up in forecast wind gusts. This looks like a 6-9hr event. With the worst winds forecast 12:00-18:00.Gusts widely from 70-90mph. In Stratford there are a lot of tall buildings. Even on a windy day the wind is often strong due to tunnelling. Around the City of London and Canary Whalf there could be a fair bit of damage this weekend. Most of those builds have gone up in the last 10-15 years.I feel a significant noteworthy event this weekend. Time to batten down the hatches. I suspect the two premier league matches and other sporting events to be cancelled. Does anyone have the latest ECM data

Has anyone seen this 18z run for gusts at 192 hours ?
Off the scale stuff with gusts probably in excess of 110 mph in the Channel

Just hope for our sakes that it'll be GFS who is going to end up being wrong on this occasion, not sure we'll be able to take much more punishment after Sunday's gales.

Wales gets hammered on the 18z GFS, but pretty much every county in England gets 70 mph gusts at some point on Sunday. Remarkable!
Violent storm at around that time n/e Scotland very nasty indeed

yup big H at Bailey there.
The thing is Ian I find the weather interesting but to get a trusted roofer or the tiles are going to be like gold dust with excessive cost for us all have plucker insurance but that does not guarantee anything.
Indeed, virtually all the stamps shows that high pressure ridging but the op still shows that vicious Channel low: http://www.meteociel.fr/cartes_obs/gens_panel.php?modele=0&mode=1&ech=192, so it is an "outlier"? Oh well, hopefully it'll be nothing more than a bad dream when I wake up tomorrow morning. The upcoming Sunday storm is unnerving as it is, can't be doing with any more after that, like what has been happening in Feb 2014.
150kmph is only 93mph so not sure how you've arrived in excess of 110mph which is 177kmph
No change from GFS and ecm this morning. Both have 70 to 80 mph widely. Ecm has 100 mph for north Wales and nearly 90 in the channel.
No change this morning. If anything the ensembles have upped the mean sustained speeds as the rest of the pack catch up with the operational. 23 m/s equates to a steady wind of 52 mph.
Should the rest of the pack continue to play catch up with the operational a violent week can be expected.
A signal appearing for another storm in the early hours of Thursday 13th.

Met Office forecast for my local area not that severe compared to what the models are showing.....https://www.metoffice.gov.uk/weather/forecast/gcpu2mjnb#2020-02-09Is that data known to be accurate? Mean wind speeds of 25mph & gusts to 50 ish at odds with the GFS, ECM.......

Besides “to” generally indicates an upper bound. Most would describe 56, 58, 57 as “...gusts to 60 ish...”.

I’ve studied these events for many years. A significant majority of the damage (trees, buildings) with these storms occurs from one or two rogue peak gusts (often associated with trough passage or in rare occasions sting jet impacts).
In a general swathe of 60mph gusts you might get a rogue local 70mph gust and off go your ridge tiles.
Here in The Solent I’m advising against travel tomorrow afternoon but the ‘highlight’ could be the coast. The overtopping still high tide is going to be something else.
Obviously we have to wait and see but most of the models and the Beeb forecasts suggest 60 to 80 mph for your area. These automated forecasts are notoriously poor for this type of event.

The Aperge model shows gusts to 130kph in some parts of the South/SE.What time are the warnings updated. I wonder if we may get a red warning issued.Neil, are you hearing anything?
Amber will be expanded in this morning’s revision round. Red unlikely but you never know - if it is it will use the 12Z or 18Z data and real time to assess the very latest.
