Fog Warning for Ireland 19th-20th Nov

Villain

Met Eireann have a Weather Warning in place this evening:

STATUS ORANGE

Fog Warning for Ireland
Mist will thicken into fog in many places tonight. This will lead to greatly reduced visibilities and poor driving conditions. The fog is likely to clear only slowly during Thursday.

Issued:Wednesday 19 November 2014 14:00
Valid:Wednesday 19 November 2014 20:00 to Thursday 20 November 2014 12:00

Also a risk of some Frost based on their latest forecast but the GFS model has jumped from a low of 1c on 06z to a low of 6c on the 12z which is interesting and confusing.

However whether or not Frost does add to the woes, dense FOG will cause issues for those travelling tonight and in the morning so allow extra time.

Visibility forecast for the morning from NMM4

Fog is so under rated. Such a beutiful weather phenomenon.

I remember flying over Brussels, there was a blanket of fog/mist. High rise buildings poking through. Looked great.

Wish all commuters well tomorrow.

No fog so far in galway city or along the connemara coast.

I know it's hell for drivers (I have to drive 30 miles to work every day) but I agree about fog. It somehow calms everything down, and deadens sounds.

But be careful tomorrow. Always remember to drive at A SPEED THAT WILL ALLOW YOU TO STOP WITHIN THE DISTANCE YOU CAN SEE TO BE CLEAR!.

It's amazing how many lunatics inist on driving at high speed in low visibilty. We've only had one major traffic pile up here but another one will happen because drivers won't slow down. Rant over.

FYP

Stay safe everyone, fog is lovely except when you're driving or sailing in it :eek:

(apologies if this is O/T)

Yeah agree,something eerily calm about it

The fog is rolling in, it's accumulating in benburb-street. It's getting bad out there now with dense pockets of fog on the back-roads along streams and rivers, so slow down...

Just been out for a look here (Galway city east) and it's as bad as the last couple of mornings.. Gauging distance is incredibly difficult with other vehicles due to the 'flare' from both headlights and taillights, so take your time and be safe on your travels this morning.

All clear here.

Just looked out the window where I am in Cork City and absolutely nothing from what I can see....

Inversions are pretty cool, Vancouver gets them often enough and the view from the slopes is spectacular.

Foggy here in Dublin city centre but not quite as bad as I was expecting. I'd imagine any poorly lit roads will make for a nervy drive this morning.

Ogie84

Bit of fog around Cork City but nothing particularly heavy or noteworthy.

Akrasia

I was driving to work from ennis to shannon at 7.30am this morning and parts of the journey had visability of less than 30 feet

Didn't stop morons tailgating and undertaking each other on the motorway though

charlie_says

Plenty of fog here in Galway city area since early this morning.

Bloody cold too. I hate the cold.

leahyl

The fog appears to have actually thickened in Cork City since this morning cos there was nothing when I was on my way to work this morning, but now it's really foggy!

Sparks

Visibility is about 100m or so on the Meath-Dublin border at Mulhuddart.

Yeah it has significantly thickened here in D2 in the last couple of hours. Visibility seems to be around 200/250m

Simon Gruber Says

It's been perfectly clear here in Bray all day.

mojesius

Can barely see anything out the window in Docklands, D4 I quite like it though

jacool

Was heavy in Carrigaline this morning. The 08:00 headlight count was over 90%, which is high for this part of Cork!

Supercell

Thin fog here this afternooon after been nice and sunny this morning.

Wine Goddess

Fog has got really bad in Firhouse and is actually worse now than this morning.
Was in Rathmines earlier and it almost had disappeared but noticeably thicker out here.
Visibility down to about 80m.

Just talked to my missus who drove up to Belfast this morning. Apparently fog started at Sandyford and didn't stop until the border.

Oscar Bravo

Fog has lifted a little in Castlebar but it remains very murky.

Villain

Fog has Cleared the Carlow/Wicklow border but remains very dense in Carlow Town

MJohnston

It lifted a little here in D2, but now it's back to 200m visibility, and the sun is basically gone, so might thicken up a bit more later. Glad I'm not driving home tonight.

Edit: seems to thickening quite rapidly at the minute actually, might be less than 200m visibility now. I'll get a photo.

pistolpetes11

Never Lifted in Newbridge , getting a lot thicker now also

pad199207

Never lifted in Naas either

MJohnston

This is Grand Canal Dock:

loveisdivine

Its been pretty heavy here in North Dublin all day. Lifted a little around lunch but in the last hour its gotten quite thick again.

Would someone like to explain the conditions/climate that lends itself to this persistant fog. On M 50 and only few hundred meters visibility, not driving

joujoujou

Twas very quiet - usually all the planes to/from Knock Airport are flying above my house.



Not today. :pac:

Fog forms once evaporation into the air results in supersaturation. If the dewpoint depression is small after sunset, clear skies will cause radiational cooling of the air quickly toward saturation. The dewpoint can increase due to a rain shower, previously saturated soils and irrigation. Since vegetation and bodies of water evapotranspirates moisture, fog first forms over grassy and nearby rivers, lakes or seas. Fog is common in situations where a daytime shower saturates the soil, vegetation and boundary layer and then skies clear in the evening into the night hours.


Low layer inversion is capping any of that mositure to rise up higher...


Winds picking up later will help clear the fog in most areas by tomorrow.

Button_y

We had a beautiful blue sky most of the day here on a hill. Everywhere lower around us was covered in thick fog.

Glebee

Beautiful sunny day in Tralee today

MJohnston

Surprisingly it seems to be a bit clearer now that its dark. Or maybe its not surprising as I don't know the science of it well enough. Or possibly its just because lights are easier to see through fog than unlit concrete?

diceyd

Does anybody know if the fogs bad on the m50,ive to drive to nct.

ninebeanrows

With south-easterly winds set to freshen overnight, the fog won't last too long

Rikand

Good to hear. Flying into dublin tomorrow afternoon and don't want any diversions

marno21

Fog was absolutely ridiculous on the N20 from the N20/M20/N21 interchange to Charleville yesterday around 2:30. Was difficult to even see the car in front. Visibility was grand until I left the M20 and climbed up onto the N20 at the interchange
