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.

In Dublin there was about 30 minutes of winds around 11pm that reminded me of winter storms and then it went quiet, didnt hear any of the predicted thunder. Met has thunder between 1pm and 2pm today

I blame Fianna Fáil.
For the weather.

I made an attempt to ring Kildare county council yesterday around half 4 just to I suppose assuage my fears that they were prepping for this.

All I got was an out of office coldly metallic robotic answering machine.

In fairness, my pear tree produced its first and only pear this year.
I’m afraid to check if it’s still on the tree.

The pear did not survive.

Council responsibility?

Probably. Although, given the volume of water coming off the hills, the culvert probably couldn't have coped even if the storm debris hadn't clogged it up.

It's not the river bursting its banks that was the issue this time, there is a culvert up the old Baltimore cut that takes all the run off from the hills, that culvert got clogged so the run off goes down the road and through the ally next to the hotel to the river instead. It happened in 2016 I want to say as well.

Council responsibility?

Massive tree came down in my neighbour's garden in South Wicklow even though the winds weren't particularly strong here. No damage done thankfully other than the tree itself. None of mine came down, was very worried about them though. Have a few that are well over 100 years old and would be awful to lose them.

Thunder and lightning in Cahir now

Thankfully in North Clare it's business as usual, hardly any debris on the roads and the river's are swollen slightly alright.

So sorry to hear about people's property businesses and roadways blocked and flooded.

The engineer's in this county need to ask the older generation how it was done back in the day.
I'm know some aul fellas in their 70's and 80's who'd run ring's around the modern day engineer's in country councils.

Because diverting river's and drainage schemes in the last 30 year's have been a national catastrophe.

There's some idiot's out there who have no clue about how river's streams and lake's work...

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.

This would explain the last few Cork-related posts!
