[Matty M]

Gusts approx 90mph into West Coast of Scotland.

One of those situations where looking at the charts here before the event is nice, however the eery element remains that a system like this can catch folk out.

 

The introduction of the cold air is rapid.

 

6am - noon - 6 pm

Can you throw up wind chart 3 hours later? Cheers

It's a damaging storm alright. Funny thing is, the news would rather waffle on about Nijelly Lawsuit and random things that don't really matter... Should really be warning people, especially in Scotland and the far North of England. Edited December 4, 2013 by Glenn W

Yes and it isn't just the far North of England, exposed Scotland, there is a large portion of the central belt that could get hit my 70-80mph gusts.

[Glaswegianblizzard]

Becoming quite breezy here, and what sounds like some really heavy rain out there too.

[johnholmes]

just to take a look at some of the aspects of the low as it is now

 

The Fax charts

http://www.weatherch...rg/ukmomslp.htm

Satellite charts with the infra red movie version perhaps the best to track but others also very interesting, for the Dundee ones you need to register (it’s free and easy to do)

http://www.sat.dundee.ac.uk/auth.html

http://www.yr.no/sat..._animasjon.html

Actual weather, several places to bookmark

For actual weather on the Shetland Isles

http://www.shetland....ast/default.asp

Regular hourly reports from sites all over the UK and abroad if you wish

http://www.xcweather.co.uk/

Track the low from buoy reports although many are south of its expected track

http://www.ndbc.noaa...d_Kingdom.shtml

 

Charts showing the progress of the low

Obviously 6 hourly updates from Exeter of their Fax charts

And this site, remember it is a computer generated chart and is at times not as accurate as the Fax for the same time. It is very useful to watch its general track, deepening etc.

http://meteocentre.c...〈=en&map=UK

for those that understand the WMO code this list all the stations in the UK in the SYNOP code with stations in Shetland and Orkney fromm03001 to about 03017, to see what the SYNOP for Torshavn north of the track is giving the type in 06011, all of them report every 6 hours, 00,06,12,18 and some every 3 hours

Thanks John, great information there.

North Sea is going to take a battering, hopefully nobody is swimming to Holland tomorrow...

The animation on this is great. Should probably have some scary foreboding background music to it. 

[lorenzo]

Fax John mentions deserves a post, it is a beauty.

Wouldn't take them very long.

 

Rather sobering to realize that the low will deepen by 40 mbs from its 18z pressure of 1000 mbs (from CMC analysis), imagine it is around 992 now. I expect the effects will be rather short-lived in the UK and there may be somewhat of a let-down for some, the gradient tightens rapidly overnight then relaxes almost as quickly tomorrow. It's quite a different story for the continent where damaging wind gusts could last several hours, which tends to escalate the total damage.

[Geordiesnow]

Wow, this Northerly is getting toned down in terms of length within each run, its just a quick sweep and its blink and its gone pretty much. 

 

when oh when will we see a true Northerly flow from the Arctic that is sustained for a couple of days because I havant seen one for a couple of years now, Atlantic ridges which looks promising get flatten nearer the time by a mess of low pressure over Greenland.

Guess Leeds City Council are not taking any chances.. 

A major traffic route into Leeds city centre will be closed on Thursday following warnings of high winds.

 

The road is the main route into the city from the south and is used every morning by thousands of vehicles.

 

It passes the city's tallest building - the Bridgewater Place tower - which a coroner ruled this week can influence wind conditions.

 

She recommended the junction beneath it should be shut to all road users when wind speeds reach 45mph or more.

 

Leeds City Council says Victoria Road, as well as Water Lane and Neville Street, will be shut from 06:00 GMT on Thursday.

Getting really wild now with things blowing over.
