Lightning was incredible over Naas with torrential rain

That was the one of the best weather days Iv ever witnessed,dublin 11

It's amazing how often lightning is misspelled (not on here of course)😁

Fairly low key affair in my part of N Tipp, handful of flashes a couple of rumbles

Storm 10

Hopefully that's it for Galway had enough of noise and blinding lights hope to get a good night's sleep

That's mad. Thanks for posting it.

Glad I replied to your post now.

Just seen a strike hitting the same spot about 5 times about a half mile away.

Reminded me of this.

The second closest strike was about 2 seconds away, there was an unmerciful bang! but didn't see it

Just thinking, with the frequency of strikes across the country today, there's bound to be some significant damage done in places.

From 12 noon today.

Just been looking at blitzortung.org. I can't remember ever seeing so many lightning strikes over the Irish Sea in the last 30 years, pretty much the entire area from Dublin across to Holyhead, and down to almost Rosslare to Fishguard has seen a huge number of strikes over the last while.

There wasn't much close to Ashbourne, the closest based on flash to bang time was about a mile, some of the more distant strikes rumbled on for a very considerable time, and for sure, it's been an interesting day at the airport, I'm glad I'm not working on the ramp any more, today would have been very challenging.

I hate to say it, but the sferic system met eireann uses is absolute crap, and most certainly here for the western region.

Auto correct often a curse!

Looking south out the window in Galway city and I see yet another flash in the distance. Dry here at moment.

Had to cycle home through that thunderstorm just as it began at 10pm, Christ almighty it was unpleasant, the drains immediately overflowed and cycling downhill involved going with essentially a river, growing much larger as the drains pumped out water rather than sucked it away.

Strong smell of sewage in a few areas too, rather nasty. I don't ever think I've seen a day with so much thunder and lightning as today.

Today around 12 there was serious thunder overhead in Wicklow and I heard what sounded like glass cracking. The windows were literally shaking from the force I've never seen anything like it. These are massive triple glazed windows, so wouldn't be easy done. Had to go away for the night but after seeing some of this evenings activity I'm fully expecting to come back to a shattered window from this storm. Mad stuff never even knew that was possible.

Looks like a blitzkreig over in Wales!

I'd waited about 10 years to get this one properly!

I think I got unlucky. I left go karting at Kylemore karting near parkwest at 21:45 yesterday evening. There was a fantastic flash of lightning as I was starting the car, to the west. I drove up the Naas road to the red cow. Saw one more flash along there. One more between junction 9 and 7 of the M50 and four more between there and junction 8 of the M4. From there to Trim, I saw four more flashes, arriving in Trim at 22:30 on the button. Whilst the flashes themselves were fantastic to look at, the thunderstorm was in no way prolific with lightning, quite often there was 4/5 minutes between strikes. Averaged about 10 strikes in 45 minutes or one strike every 4 minutes and 30 seconds...... That's nothing much, by any stretch of the imagination. The individual strikes were very impressive though, I will admit that.

I guess I was spoiled by the multiple storms in Longford during the thundery spell in the summer, when I was usually seeing strikes every 1 to 2 seconds. How quickly have I become spoiled!

Blasphemy

Delighted for all the people who got strikes. I think we got 2 rumbles in athlone. The sleeve bloom thunder shield stopped a lot of storms from reaching us

Noticed the first flash yesterday in Portnarnock N Dublin around noon and it but from there. Had to get on the road around 14:30 and drive to Galway with a stop in Athlone. Wasn't too bad at that time aside from lots of surface water.

It started picking up big time around Ballinasloe at 16:30 with a superb light show as far as about Athenry. Galway was dry. Left Galway around 19:00 and soon out the road it picked back up again with huge flashes to around Ballinasloe again.

Had ro stop again and was back on the road about 20:45 heading for Dublin. The further east I got the more it picked up with intense lightning from Kilcock / Enfield all the way home.

Can't recall when I saw lightning like that before in Ireland, reminded me of summer storms in Florida.

Watched the storm here in Donabate from around 10 onwards and earlier than that, watched it off the coast of Skerries go north towards Co Down. Lightning wasn't the most frequent I'd seen in a storm but when it sparked, there seemed to be several intense multiple discharges rolled into one. Thunder seemed to come from high up in the cloud, so perhaps these were "elevated storms". The precipitation that fell was the big heavy continental style raindrops.

I think the reason for lightning of this nature (and frequency) is that the whole area/band was on the trailing stratiform type. you can read up more on the different types here:

For the record, to note the first map is from the ATD system which is more tuned towards CG strikes, as the storms were quite elevated this chart wouldent have accounted for all the sferics and as the piece from Met eireann states it might just have accounted for 10% or 20% of all the strikes.

From Met eireann about the ATD Network https://www.met.ie/science/valentia/lightning-detection

Also from Met Eireann

Lightning

The ATDnet Lightning Detection System is optimised for detecting cloud-to-ground lightning strokes and flashes rather than cloud lightning (inter-cloud and intra-cloud lightning). The majority of lightning occurs in the storm cloud itself or between clouds. On average approximately 10 to 20 percent of all lightning over Ireland are cloud-to-ground strikes.

Lightning locations are sourced from the WMO SFERIC (SFUK) messages. Some atmospherics may not be detected. Isolated spurious returns can also occur. Detection efficiency is variable, ATDnet is capable of detecting in excess of 90% of cloud-to-ground lightning flashes over Ireland. Typical location accuracy is estimated to be around 1–3km, or less. Further information about lightning detection at Valentia Observatory is available here.

We are most grateful to the UK Met Office for the use of their Arrival Time Difference (ATD) lightning location data.

Lightning strikes, when they occur, are displayed as a cross. Initially they are red but change to orange and then yellow after a period, then disappear.
