Heavy Rain - Flood risk

WolfeIRE

A lot of rain forecast for Ireland in the next five days, with medium term outlooks predicting further atlantic systems will be crossing the country.

Last November saw a similar set up which resulted in serious flooding throughout the country, particulary in counties Cork, Clare and Galway. The only difference this year is that the current wet spel of weather has not been preceeded by a record breaking wet summer, as experienced in 2009.

The water table is pretty much at capacity according to http://www.met.ie/agmet/smd_wds.asp so any sustained rainfall will lead to flooding as the water has nowhere to go.

Latest warning from Met Eireann.

I'm in Riverstick now on a hill open from the SE right around tonthe west. My iPhone is getting soaked as I'm typing this bit the wind has seriouly picked up. No way p measuring speed but heavy rain is falling sideways. And trees are flexing a lot. Right back to the 4x4 for me now.

sunbabe08

heavy rain here in cork. wind picking up again. love this type of weather

up for anything

Well it is half term so of course it is going to be wet and windy. Five days should bring us nicely to Monday which I predict will bring clear blue skies, cold but no wind or rain all day till 3pm.

Wet but not pouring here in KK and no wind to speak of but with the recent rain the leaves have turned into a sodden mess everywhere which can be worse than ice for skidding on so watch out on the roads.

Very windy on the hills in KK...

John2009

Just a clip from a passing shower at 9:45pm, taking with my Panasonic Lumix TZ7 sorry about the strong blue streaks but its typical of CCD sensors in cameras,

the camera is brand new and this is actually my first night video with a digital camera, 720p available on the Youtube clip

I'd forgotton what serious rain was like, but it looks like we're going to make up for whatever deficit there may be in the Deise soil.

Maybe not, the wave forming along the front has pushed the front back slightly as a warm front, this is likely what happened at the Kilkenny station as per the graph. Torrential rainfall rates along the path of the wave as it moves northeast through s.e. Ireland today. Roches Point already showed one hour with 14 mms.

TheMilkyPirate

Looks like were gonna get the full force of this in wexford town which i'm quite happy about because i have sweet f a to do all day except sit in my room watching sky HD and listening to the rain smack off my roof

Its stopped raining here and by the looks of the radar we might be finished with it for now.

pauldry

Still lashing in E Mayo. It was spittin in Sligo when I left at 834am.

Southwest seems clear now but the rain is not going West to East it is going South to North and East very slowly so late evening before Leinster sees a clearance.

Last November we had heavy rain, but my barn never got flooded by rain water rushing down the hills to flood the people who live in water friendly holes.....
The rain was so heavy this morning that the drain burst it's banks and some entered the barn, ok lucky there is nothing there that it can damage.

One would have thought it would have happened last year.

rua327

Still raining heavily in Cork. Carrigaline / Crosshaven road, and around are badly flooded. Great craíc :pac:

snowjon

Very dark and very wet with occasional torrential bursts of rain - no sign of flooding just yet....

10.6C

The big lump of cloud currently covering over half the country(met eireann's radar) is very slow moving,wont be surprised if there's decent sized floods in places this evening.

Min

I hear some of the roads around Kilkenny county are currently flooded.

Temp has taken a massive dive in the last 30 mins from 14.1c to 9.9c

There was very heavy rain at around 9-11 this morning. It has been lighter ever since. It certainly seems we missed the worst of it anyway.

Look at the line between 8/9 degrees and 14/15 degrees at the east coast where the front is passing!!!

Lady_North1

So dark that the street lights have been on all day so far....... Real duvet day.

The wind has picked up here markedly in the last hour from a dead calm at midday to near gale force now! The rain has eased a little bit and the temperature has shot up to 14C

snowjon

Really strange day here according to my weather station - since 11am I've recorded 19mm of rain, which is not unexpected.

However, at midday, the temperature jumped from 10.6 to 12C in 5 minutes, then slowly dropped back to 10.1 C at 1.15pm. Then it shot up again to 14C at 1.30pm, and just now it has dropped back 3 degrees to 10.4C in a matter of minutes. The rain has been relentless throughout, but the wind suddenly picked up from near calm conditions to near-gale at about 2pm.

Torrential rain falling just now - the heaviest I've seen all day - almost tropical intensity

Storm 10

Today in Galway has been like a monsoon with torrential rain very bad floods on the roads and traffic jams from hell.
