I just woke up after the night shift. What was the highest gust in mainland England and what was the highest gust in France and Channel Islands? Cheers

 

207 kms per hour is approx 129 mph.

My daughter and I recently visited the site in St Clement where a tornado caused a tremendous amount of localised damage at approximately 11:45pm last night. Here are a handful of images we took from the area where the main damage occurred ...

I am currently on the TORRO website right now because I am going to share the images that you taken.

Realise that image file does not need the postcode

Yep, the Kensal Rise one of 7 December 2006, which was rated as a T5

It was an interesting morning, to say the least.

Well I went to Dawlish this morning to see what was happening and I wasn’t disappointed

Thank you GSP, look at these next two, this huge slab of stone was torn off the seat by the sea wall about 20ft away. Incredible power

Very interesting. Absolutely no expert but non toenailed nails ripped out the ground. Plus other photos, this looks like a level 6/7 kind of damage indicator (corresponds with the T scale but shift downwards one, E. G. T5/6 damage indicator) with some exterior walls close to collapsed . So high end EF2 up to mid end EF3 damage. Suspect it'll end up high end EF2 as I don't think contextual damage is enough but possibly if someone knows more about the engineering of nails more than me and foundations of these particular houses then it could be EF3 level. I'm pretty sure the strongest since 2006?

Similar tornado at a similar time, last year in Northern France but slightly stronger damage. Got a T6, so I think this one will get a T5.

Incredible, and I thought the display I had yesterday was very good!

Toenailing is insufficient for wind loads should use  Simpson hurricane ties or similar

I would imagine US tornado damage indicators and the Torro system are very similar in their damage indicators.

Fantastic photos and a stark reminder of how the weather can be so powerful .

The wind is making a racquet every so often still , even more than last night.  It was extremely wet here last night , but now gusts are still gusting .

The models I think performed very well with the track of the low and development and implications.  Probably 8 out of 10 ☺

France getting more worried about extensive flood risk. Another storm hits Spain tommorow.

We must not only monitor the violent winds but also the very heavy accumulations of rain between now and Saturday in places which risk causing flooding, with soils which are now saturated with water on the surface. Large amounts of rain expected: - in northern Hauts de France in connection with the occlusion of #Ciaran which will circulate from tomorrow morning to Friday morning. A few more mm then Friday under the trailing sky. This will inevitably overflow into areas which have already had flooding near the Côte d'Opale. - on Landes and Pyrénées Atlantiques by blocking effect from tomorrow until Friday evening. Passage of an occluded front Friday morning and secondary lines before and after. We could reach close to 200 mm. Flooding to be expected and river levels to monitor. - on the west of the Massif Central in particular tomorrow afternoon behind the cold front under showers which will often take on a continuous nature. The watercourses below may overflow a little. - over Alps and east PACA under the cold front tomorrow afternoon with a possible stormy character. Certain areas to watch out for near Mercantour with possible landslides in particular. Possibly some localized overflows. - on Corsican reliefs exposed to Libecciu with continuous orographic forcing giving regular rains. Passage of the cold front tomorrow evening with possible storminess. Accumulations of more than 150 mm possible at altitude.

Terrifying! As more pictures and videos are uploaded, aren’t people on the mainland very pleased they did miss all this?

Traumatic, and we feel for the people of the Channel Islands.

I expect we’ll see this loon for many years to come in various extreme weather programmes.

It's amazing what the sea can shift. I've seen some of sea defences at Hornsea removed by the sea over the years. Not much left by now.

So had a yellow warning for wind. That wasn’t too bad for us. No yellow warning of rain and flooding.

 

I however do not envy some of the scenes seen in other places though. We had it light.

To get large hail like that outside the summer season must be almost unprecedented. AFAIK every large hail event I've heard of has occurred during, or at the breakdown of, hot weather in the summer months.

I'm just glad the worst winds of this storm kept south of us here.

Severe weather fascinates me. I love tornadoes. But moments like that remind me to respect it. I wanted a slice of the action but ended up thankful that I got what I got.

[Metwatch]

Would like to say a massive thanks to the useful input from people like Tamara and Roger, Nick F and Jo with the updates on the site, and also all the reports and photos coming from those affected by the storm.

And it's not just today, but this autumn has certainly been an action packed season for many of us, filled with heatwaves, thunderstorms, windstorms, flooding to even strong tornadoes (just missing widespread low level snow!).

I wouldn't be too surprised if we get another windstorm or 2 in the next few weeks. Personally I don't see much in the way of the current unsettled pattern relaxing anytime soon. The British weather can throw in some surprises and switch up quickly with just about anything, so fairly often the 'expect the unexpected' mindset is a good way to go about things in the mid-semi long range of 2-3 weeks ahead.
