Potential Extreme Wind Storm - Thursday 8th December

ninebeanrows

Well originally i anticipated the low would slam into Scotland and the northern Isles but over recent model runs the deep low pressure system has been placed further south with northern counties of Ulster at risk of extreme winds.

The exact track and depth of the low will be difficult to pin point until tomorrow evening. However i feel it necessary to start this thread to put a warning out there.

The system is picked up by the ECM as a vicious system with exceptional winds at its left exit perilously close to the north coast.

Please stay tuned, it will turn windy this evening and overnight across much of the country but this event is expected to hit Thursday and it will be tracked with great concern by Met.IE / Metoffice and your boardsies.

There is also the risk of blizzards if the system does reach the mainland.

Wind gust estimates at this stage are uncertain but this could be extremely severe and we are considering the possibility of gusts in excess of 150km/hr.

Of course it may not come to pass or move further north.



While the GFS throws an extreme gradient a little further north

Is this the same system that Met E are saying will bring potential large amounts snow on saturday night?

No. That's a different system.

Interesting few days ahead then.

Blizzards? Actualy blizzards? Oh no, I'm going to have to get a new F5 key...

It looks potentially bad for Scotland and Northern England alright. A lot less for Ireland if the 12Z GFS track verified.

Even though the 12Z track shifted south, these lows usually end up tracking further north than the models forecast. Still though, its an interesting one.

Loving the weather at the moment , even without the snow in my back yard the weather of late has been interesting to say the least

13th/14th also needs to be watched for a potential severe wind event. The ECM and several of the GFS ensembles show this, some with extreme low pressure.

:rolleyes: Has the bottom of the chart been cut in the budget ??

How low pressure are we talking ?

Oh crap.

Dont mean to go off topic folks but I am gonna have to watch this like a hawk. On a ferry ferry - the big ones, on Friday morning and back Sunday night, with drive from Holyhead to Liverpool.

Anyone take a guess what all this will mean. Will there be any disruption or is to early to guess ???

Thanks

The worst winds to hit the Irish sea are likely to hit Thursday evening, and i would expect Thursday afternoons crossing to perhaps be delayed as winds in the Irish sea are expected to be sustained 50-60mph gusting 70-80mph.

Some woman was on the telephone saying there was going to be a hurricane...:rolleyes:

Every wind event is called a hurricane by some mad owl one and then spreads like fire. We should be so lucky!

i was trying to think of the Micky Fish quote

Storm is tracking further north on the 18Z so far though it looks a bit more intense.

Su Campu

It almost looks a replica of Carmen in November 2010.

Hi maq just wondering what your thoughts are on the storm thats on the models for monday and tuesday next. sorry i know its off thread topic.

ninebeanrows

Not that far north from us, deepens slightly earlier in this run.

gotta say i dont think this will pan out as severe as some are sayin [ no expert view just a follower] but this kinda setup has been predicted so many times in the past and 95% dont turn out as bad as predicted but i can understand the concern because its still possible. still reckon people in ulster should keep up to date with this system

Su Campu

That's some hurricane-force gradient over western Scotland and NI! :eek:

naughto

your some man for the maps Su Campu keep it up

maquiladora

Even though its a little further north on the 18Z, because its more intense the max gusts for Northern Ireland are actually higher than on the 12Z. 70-75mph gusts just off the north coast.

Scotland takes a hammering.

It's less than 48 hours out and there is good agreement between the main models on this event so a major downgrade at this stage is very unlikely. The track and exact intensity still has to be nailed though and that will determind who gets the windy conditons and who gets the stormy conditions.

Harps

Amazing how quick these things can show up, this time last night there was nothing but a typical windy day across all the main models yet suddenly the biggest storm of the year pops up only two days away!

I know the exact track and intensity will change with every run but its looking like a potentially dangerous storm for around here

as i said im no expert an your the guys i look to for serious stuff but it seems ive read alot of threads with similar set ups with the low t o our north and its ended up shifting further north as it closes in on us ........is there anything different with this perticular set up that makes it different,met eireann are not giving any weather warnings for this and its only 48hrs out?

maquiladora

NAE has 75mph sustained winds for parts of Western Scotland for a time.

Su Campu

This is as similar storm to the one that hit the Faroes a week or two ago, bringing 74 knot sustained winds. The good thing is these winds will be in an area with a lot more observing stations, so we should learn a good bit more from this one.

eskimocat

Lads i don't know about later this week but tonight is sure getting gusty! The lights flickered here too. Don't go by the weather station readings, its located in a nice cosy garden tucked away...:rolleyes:

Oh lots on the weather forum lately... love this time of year

Look whats comin on the 18Z, I mentioned this earlier about the 12Z ensembles....

Santa! Who else?

18Z GFS is showing another storm with stronger winds for Ireland next Monday/Tuesday.

Deep Easterly

Latest from EMHI HIRLAM 18z run.



Just to give the actual legend more detail and just to note, these are forecast mean wind speeds, not gust speeds which will be much higher!

10m/s = 36km/h | 19kts | 22mph | BF 5
13m/s = 47km/h | 25kts | 29mph | BF 6
20m/s = 72km/h | 39kts | 45mph| BF 8 (Gale)
23m/s = 86km/h | 47kts | 53.7mph | BF 9 (Severe Gale)
30 m/s= 108km/h| 58kts | 67.1mph | BF 11 (Violent Storm ) :eek:


Extent of strongest winds seem a little more south than earlier runs with the chance for gale to strong gales in many coastal areas of the country with potential for mean wind speeds to reach storm force 10 along the north coast (doubtlessly with damaging higher gusts). As for the Hebrides, looks pretty darn serious with sustained violent storm force winds. Very very rare to see that being indicated on these maps.

wow now thats a storm

je55ie

OUTLOOK ... Make a will (if you believe the 00z GFS run) ... seriously, the model consensus remains unsettled and rather cool, but one model shows an epic windstorm on Thursday 8th into Friday 9th. I am hoping this is a typical model teaser because even 75% of this storm would be nasty. With the full moon in that time frame, energy levels are high and a storm surge would accompany such a storm on the west coast. We'll continue to track this potential which has to be rated slight at this time frame.

...... MT last week

Yeah, we usually see that kinda stuff from the GFS at 5(+) days or so, but there is good model agreement for this to be quite severe for Scotland at least.

Should be a really interesting one to follow. I just hope nobody exposed to the highest winds gets hurt or worse.

We used to slag OwenC about his boasts about his local climate extremes, but when you look objectively at it, he was not all that wrong! :cool: But yep, let's hope this will be a fun, rather than a tragic event and that people will take due warning whether or not this storm potential plays or not as currently indicated.

Really interesting weather this month you have to admit, plenty of gales about.
