Some charts say its not really Sundays low that will be the worry but rather Mondays (06:00 Monday 28th). It has a low of 970mb tracking over Northern England resulting in very high winds over the majority of England. Sundays low, although similar magnitude tracks north of Scotland with the resultant high winds over Scotland where they are somewhat less unusual.
In article , The Natural Philosopher scribeth thus
Looks like it might come as predicted;!...
Ah. looks like the worst hit will be London, then.
And the Thames Estuary. Now where is the London Array of wind turbines again?
Furher updates from SWMBO is that whilst its not clear that it WILL be major, the pootential conditions FOR it to be major really exist.
Stop those butterflies flapping in Brazil! Kill them all! The precautionaty principle says you have to, just in case!
If CO2 could cause climate change, how much more so could butterflies!

Oh dear. Have to watch out for turnbine blades scything down the road.
That seems to be the case on uk.sci.weather Got a link?
I find spiders proliferate a few days before we get windy weather here in Stoke on Trent.
you may jest, but what is REALLY alarming ... on whatever site is my wife keeps forgetting to send me a link to ... is that there appears to be a likely squall line forming right across the UK with winds in compltely different directions on either side.
If that crosses even shut down turbines, they won't be able to turn into a wind thats boxing the compass at 100mph gusts + ... they rely on blade feathering, turning to face the wind, and braking to minimise loads - if the wind direction changes faster than they can slew, they could be in serious trouble.
Falling trees are one thing, but these babies stand in the windiest place, and they are a lot bigger than trees.
Brake failure on a shut down turnine, or failure of the feathering will destroy the thing totally. And a shed blade in a 100mph wind doesnt bear thinking about. It could fly for miles.
Also if we get tornadoes, I wonder how solar panels will cope :-)
intersting times.

It was not said entirely (or even mostly) in jest...
Having seen how they are fixed the roof will be stronger with them than without. They might even stop the tiles being broken by flying debris.

Ah that's their real use, sacrificial roof coverings.
the other place that has moe stuff gathered in one place is netweather.tv
ROFL :-)
Miles might be pushing it but certainly a very long way.
The reporting in the secind video is not quite correct. Maybe. My analaysis of model aircrft propellors (I have designed a lot of them) showed thet the dominant cause of fauilure (apart from crashes) was not centrifugal force, but the actual thrust generated by the propellor itself.
Now that may not be true of turbines, but there is another issue: In use the blade tips operate - because its about the most efficient place TO opearate - at around 200mph. Push that to 400 or 450mph and parts of the airflow go transonic, especially in a 100mph wind! when the transonic wake hits the tower, gou get a mighty pulse of energy into te structure, and fatigue may play a part. That variation in thirsut is taken buy teh blade root .
In the videos you can see that a blade snaps and hits the tower, which crumples like a beercan.
That suggests it failed more or less as the blade passed the tower.
Once failure of any part of the rotating structure happens the out of balance forces are massive, and the whole thing disintegrates.
In another report I saw 'UFOS attack wind turbine' (sic!) what aas reported was a bright light in the sky, and the next morning the turbine was over but only two blades were cound. The conclusion I draw is that one carbon fibre blade was vaporised by a lightning strike.
Somewhere there is another disntegration that was held to be down to ice on the blades. That can be shed at up to 200mph as well.
What is clear however is that health and safety rules have had a cart and horse driven through them to enable wind turbines to be ereceted near human habitation.
They should be asbolutely nowhere within 1t least 2km of any houses and be surrounded by warning fences.
I wonder how many people have been injured or killed by being struck by storm-blown detached wind turbine blades? I would guess that it's rather less than the number killed by, say, nuclear accidents.
During a hurricane, any common or garden object is dangerous - I have seen film of an aftermath with a plank of matchboarding driven into a tree like a harpoon and left sticking out from the trunk at right-angles to it.. If you are going to apply such logic, clearly we must ban matchboarding.
If one of the flails breaks off from roadside hedging or mowing machine it could easily remove someone's head. AIUI, the containment has to cope with this so anyone on same side of a hedge as the cutter, for example the operator, should be fairly safe, but what about someone walking their dog the other side of the hedge? Obviously we shouldn't allow hedge trimmers anywhere near parks and the like, yet you see them all the time.
You also see people cutting grass with rotorscythe type mowers wearing inadequate footwear.
Clearly we must ban all these things, as they are much more likely to injure someone than a turbine blade.
And that's not to mention working and safety conditions for the clean up at Fukushima ...
"Special Report: Help wanted in Fukushima: Low pay, high risks and gangsters.
IWAKI, Oct 25 (Reuters) - Tetsuya Hayashi went to Fukushima to take a job at ground zero of the worst nuclear disaster since Chernobyl. He lasted less than two weeks.
Hayashi, 41, says he was recruited for a job monitoring the radiation exposure of workers leaving the plant in the summer of 2012. Instead, when he turned up for work, he was handed off through a web of contractors and assigned, to his surprise, to one of Fukushima's hottest radiation zones.
He was told he would have to wear an oxygen tank and a double-layer protective suit. Even then, his handlers told him, the radiation would be so high it could burn through his annual exposure limit in just under an hour.
"I felt cheated and entrapped," Hayashi said. "I had not agreed to any of this."
When Hayashi took his grievances to a firm on the next rung up the ladder of Fukushima contractors, he says he was fired. He filed a complaint but has not received any response from labor regulators for more than a year. All the eight companies involved, including embattled plant operator Tokyo Electric Power Co, declined to comment or could not be reached for comment on his case.
Out of work, Hayashi found a second job at Fukushima, this time building a concrete base for tanks to hold spent fuel rods. His new employer skimmed almost a third of his wages - about $1,500 a month - and paid him the rest in cash in brown paper envelopes, he says. Reuters reviewed documents related to Hayashi's complaint, including pay envelopes and bank statements.
Hayashi's hard times are not unusual in the estimated $150-billion effort to dismantle the Fukushima reactors and clean up the neighboring areas, a Reuters examination found."
The report goes on to detail a sickening an worrying description of how the dregs of the Japanese work force - unskilled, unemployed, debt-ridden, low self esteem and morale - are being conned into working for the cleanup, only to have their wages skimmed by gangsters and mobsters, including Japanese organised crime.
No wonder the 'incidents' keep on coming ...
I'm sure I read a stat that said more people have been killed building wind turbines than operating nuclear power stations. In fact isn't there only a single case of a worker being killed in a "nuclear accident".
I don't think it's disputed that there have been a number of people killed building wind turbines, but that wasn't either TNP's point or mine.
And I said 'by' nuclear accidents, not '>
So I take it you'll be out on the streets with the "End is neigh" sandwich board's then;?..
