Fiskar

For counties Cavan, Monaghan, Meath and Louth.
Boyne has only 2 to 3 feet to go before it hits the Dublin bypass road. Interesting times ahead.

Irish Steve

We have a small but treacherous stream (it's too small to call a river) that runs through our garden, it went from 10 cm to 60 cm overnight, and has only dropped slowly by about 10 cm during the later part of the afternoon.

110 Cm is critical level for us, after that, albeit the other side of a protection wall, it's above our floor level. November 2014, it was 85 Cm above our floor level, and due to the failure of a large pump at just the wrong time, we had about 8 cm in the house for a while.

So, we're now joining thousands of people around the country in simply watching and waiting, we've as much protection as is practical in place (and a LOT more than most) and it's ready to go at a moments notice, it's now going to be down to things like hoping no one has dumped their Christmas tree over the wall rather than take it to a recycling point, as something that simple may mean the difference between a clear grid and a blocked grid at the entrance to the piped section.

The sickening aspect of this is that the main reason for the problems is the negligence and lack of appropriate response from Meath County Council over a long period of time.

It's going to be a stressful 24 hours!

We'll be flooded tomorrow, no doubt about it, it wont come into the house but it goes around it, gives the nosey neighbours plenty to talk about though, the pond near the house is drained by a pipe way way to small and it backs up and water comes back into us, the council know about it but will do nothing

I don't believe there will be a major problem, but the ESB are playing a very dangerous game with the Poulaphuca Reservoir.

I would estimate the water level to be about 1-1.2m from the crest of the dam. If the water level reached the crest it would mean that there would be no effective control of any further flood waters.

The ESB have announced that they are increasing the flow to 45 m3/s, which when added to the 4 m3/s abstraction for the drinking water, (and without any rainfall) will lower the lake by about 210mm per day.

The trouble is that there will be more rainfall. Another 30mm of rain forecast over 24 hours will rise the level by about 250mm over that period. And it's not inconceivable that 50mm could fall across the catchment (on average given the elevation), which would raise the level by 560mm. These are my own calculations, not the ESB's, but I believe them to be accurate.

I don't see how this has been allowed to happen when the level exceeds the normal maximum water level. It leaves the middle catchment very vulnerable to any further intense rainfall events.

This cold spell really can't come fast enough.

The alert has been pulled from the Met Eireann website. Maybe they think the rain will goto Spain

I would imagine that if they were updating it, they would not remove it until they updated the file. And no alert on Meteoalarm

Storm 10

Looking at the radar it certainly will not be a problem at the original 12pm start of the Yellow alert, perhaps they are going for a later time as the front may have slowed.

thecivvie

Back online now. Extended to 9am Thursday

Irish Steve

Rats, that's probably going to mean very little sleep tonight, depending on when the heavier rain arrives in this part of the world.

Met Eireann has issued a weather advisory for rainfall tomorrow. They are forecasting 15 to 25mm of rain. The forecasted amount is generally under the threshold for a full yellow warning. It is because of the situation the flooding problems around the country and the addition to it caused by the forecast rain.

There has been well in excess of 25mm in this area of Meath between Monday and Tuesday. Looking at Phoneix Park and Dublin airport stats (probably my closest stations) for yesterday alone were over 23mm.

what part of ashbourne is that Irish Steve? I know that flooding in ashbourne is only a relatively new occurrence; i'm from ashbourne originally and never in my 20 odd years did i ever encounter any significant flooding until I heard about the flooding in the last couple of years.

You'd think they would do that wouldn't you?
But no, even to update it they often remove the original warning, and then code up a new one

Graces7

Heavy solid rain music last two hours here. Lying water in fields again but cattle are grazing contentedly. Wind slack still. South Kerry mountains 400 asl.

Radar shows front slower and later than modeled.

Dunno what previous model runs were like but this seems pretty spot on.

Same model yesterday had it reaching Carlow around now

Will slower mean it dumps more rain over a smaller area?

Stealthfins

It's raining here in West Clare.
It's also gone very dark.

It's the area behind Supervalue, Huntsgrove, Brookville, and onward towards the golf club. There were problems here (Huntsgrove) in 2000, 2002 (€120K damage) and then in 2014, the most recent very much due to a lack of maintenance,and an Irish Water related issues, a lot more houses were flooded in Rath Lodge, Huntsgrove, Ashewood and Murtagh's yard, and even more (about 50) were "technically flooded", which means the water level was within 75mm of entering the houses.

In theory, it should get sorted soon, there's a consultant's report and plan to be presented to the councillors next week, then it goes to public review, and in theory, they then start work fixing the problems, some funding is apparently already in place.

As for tonight, talk about the calm before the storm, it's almost flat calm here, next to no wind, or cloud cover until recently. As for what's to come overnight, who knows!

In my mind, as its moving slower then ot would mean a greater amount for the areas it passes over.

I'm sure it not that simple and factors like the terrain in Kerry may play a part.

Yeah, these great lumps of rock reaching into the sky and splitting the clouds open! Wild, dark and wet up here now and closing down... time for candlelight and a good thriller...and a glass of irish cream home made liqueur..Love the excuse for a quiet evening snug from the weather.... Hope everyone stays safe from floods...

Heavier stuff moving throw east Galway now after just 2mm in first 2 hours
Don't think it will amount to much more than 10 in total

Yeah, it was strange rain. Large drops but not very intense.

Rock Lesnar

Absolutely Hammering down in the north east at the minute, can hear it hitting the roof and the tele is on, another hour of this and the house will be surrounded for the 8th time this winter, the cold spell cant come quick enough

Meteorite58

6.6mm here near Tralee so far but stopped now for some time ( just 0.2mm since 18.00 )

patneve2

Moderate-heavy rain here accompanied by a south east gale. Winds might also be strong around 4am when they swing around to a NW direction.

gerrybhoy

Some shleet according to yer one on the weather here

Thargor

Absolutely bucketing down in Bray non-stop since around 19:00 this evening, very cold aswell, yet again my digital thermometer chooses an interesting weather spell to die, buy cheap buy twice.

In Dundalk. Water coming in my ceiling and dripping down the wall near the front door. Second time this week. In a ground floor apartment with duplexes above. The common walkway for them has tiles on it. The grouting in places has deteriorated badly in the last while. Management Co did a temporary job yesterday. Not working though.

Really chucking it down in greystones all evening, can't hear anything with the sound of rain bashing against the velux windows.

axe2grind

Really heavy for past few hours in east Wicklow. My local station, more than 30mm past 6 hours. This qualifies for orange status.

axe2grind

Rain has stopped, the garden stream is at its highest level on record.

Irish Steve

Another very localised event, for which I'm very grateful, we've had next to no rain here in Ashbourne, it didn't start till after 18:00, and the back edge is just clearing us now, and I'd be surprised if we've had more than about 5mm all evening. The good thing about that is that there's not been enough extra flow in the stream to disturb any rubbish that's been thrown in recently, so the grid has remained clear.

Time to go and get some sleep, I doubt there will be anything to worry about for the rest of the night.

axe2grind

Delighted you escaped Steve, absolutely mental flooding around my house with my little brook spread out over the fields. Roads in east Wicklow must be in an awful state. I'm trapped at moment but expect levels to have dropped by morning.

Graces7

Wild noisy night up here , South Kerry mountains 400 asl ,but slept well; Irish cream home made liqueur is a great help....Loud sound effects still; be glad you are not in one part of Kerry. The folk of Rossbeigh, near Glenbeigh , have had a road fall into the sea and 14 houses have only pedestrian access.. been like that for weeks and the council are havering. Hope all here are safe and dry.
