Storm Ellen - 19th/20th August 2020

M.T. Cranium

I just finished my forecast prep and discovered that various models are toying with strong developments in the Biscay region within 24-36 hours affecting some parts of Ireland within 36-48 hours, but details vary from model to model so at this early stage it's not possible to give a very precise alert for which regions may see the strongest winds.

The developments are somewhat similar to a near-tropical storm scenario that I recall from this time of year several years ago. That one moved into the Irish Sea.

Impacts are likely to be winds of at least 60 to 90 km/hr and possibly a lot stronger than that, possibly in more than one wave around Thursday and Friday, and locally intense rainfalls rapidly increasing in totals to reach 30-50 mm.

My expectation is that some clarity and model consensus may emerge as early as the 12z model runs later today but it may not be that straight forward.

At the moment, the ECM seems to favour the southwest for peak development while the Arpege model favours the southeast. While the GFS and some other models have considerable wind and rain in their output, they don't necessarily pick up on these particular developments from Biscay, keeping more of a southwesterly origin for their trajectory and no discrete lows.

This may of course be a false alarm so at the moment I am going with a level 1 tag although if some maps verify we will definitely be seeing level 2 impacts at least.

Heavy rainfalls over several days will be falling on top of considerable rainfall that hit similar areas in recent days and this needs to be factored into flooding potential.

Absolute carnage here in mid Kildare. Rubbish strewn all over the roads, hedges and greenery also. Am concerned about the back roads being impassable.

Update - roads passable but untidy with strewn leaves and branches

Shannon reported a 113km gust in the last hour, would at least tally with what was seen in Limerick

And that squall missed shannon. It was worse in limerick city east clare at about 12.20am. It was horrendous. Power was gone no street lights the rain was hitting houses and ground so hard it created a misty fog in over 100km winds

I thought it was all over. It was a lovely bright morning but we've had thunder lightning and very heavy rain in Youghal for the last 20 minutes.

Banana Republic.

Some drying in it

If these trends continue, this should be hugely embarrassing for Met Eireann. Not the first time they have cried wolf in recent years of course but the impact of their warning on struggling tourism businesses should leave them open to some very difficult questions

No need for the MET Éireann tribunal so......

There never will be be a flood system here that will handle that level of flash flood rain.

It's not finished yet - and while it may be able to handle the River Ilen in spate, I suspect that no Irish flood relief scheme can handle flash flooding of the kind that occurred last night!

It wasnt anywhere as deadly as storm Darwin or even Ophelia lets be honest. Orange Warning at some locations at a push.

Regardless, it was a remarkable storm for the time of year with national August records set.

5 trees down on my road

A big tree down just off Johnstown Road in Cabinteely, Co Dublin.

Supposed to see this as I didn’t think we’d gotten got that badly here, but obviously shows you the vulnerability of trees to wind this time of year.

Made some rain between the showers here and football rolled down the lawn, south west.

There was as 77kt (147 km/h) gust at reported at Roches Point, entrance to Cork Harbour

Just trying to get to work here in Tipp. Place is in bits. All roads out of Aherlow blocked.

It has been absolutely wild here all morning on the coast near Kinsale. We are in a pretty exposed place so are used to wind. On a scale out of 10, I would say about 7 out of 10. I’m no expert but this seems like orange level stuff to me.

Here in Mid Kerry it was pretty calm to be honest, top wind speed in my location of 62.8kmh and had about 23mm of rain since around 9:30 pm last night

I had a look on his FB page again this morning. The amount of people thanking him for getting it spot on is incredible. It's like some kind of mass delusion.

Cathal Nolan, from Ireland's Weather Channel, says it's the worst weather since Storm Ophelia, which claimed three lives in 2017.
"Certainly this storm ranks pretty evenly with Storm Ophelia," he said. "Some parts of the country have seen gusts of wind in the past few hours that have even exceeded the levels that were recorded during Storm Ophelia and of course the damage to power supplies is of a similar nature."

First it was worse than hurricane Charley, now it’s on par with Ophelia ...

We must have missed the storm in Cork North West. Just got few gusts and plenty of rain and thunder and lightning.

Sounds like you got the best bit of the storm if you got lots of thunder/lightning!!!!

Gust of 98KMH at Casement

A storm force 10 gust in not exceptional by any means for Casement but is strong for the time of year.

I happened to get up at 5.40am and the cat who usually disappears during bad weather was on the window looking to get in. I was delighted to see him. He's been in since.

Two of mine who had been out all night raced in earlier, sodden. And fast asleep since. Just the one still out. He will come home when he is hungry. They are safe out here.

No power loss here in Ballincollig, was half expecting to wake up to it gone.

Seems that only the "core" parts of Ballincollig have power at the moment though. There's a ring of power outages around the town, almost like a donut.

It was certainly an "interesting" evening and night, to say the least, even after the worst had passed over. Not much to see in the way of damage from my place. Still pretty gusty though.

Next job is to sort re the grocery delivery which will not be happening today.

Still one cat awol. Poor lad is probably hiding. Can't blame him as the wind is still ferocious. Love the look of the ocean in these circumstances.
