For us In Donegal, do you think it will anything out of the ordinary?

No. A strong gale but nothing that we don't get several times a year.

Just wondering what has caused this hurricane to travel east towards us, rather than west as they typically do? Is it due to where it first formed?

I agree. Looking at the latest estimated track - the storm looks like co Limerick will experience high wind speeds similar to that previously estimated for Clare / Kerry / Cork.

The geography if the county doesn't help either with little or no protection from South westerly winds. The open esturary of the river Shannon running effectively north county Kerry all the way to Clare coupled with the relatively flat geophysical landscape in the West of the county.

The east of the county also has a major mountain range which tends to exacerbate storm conditions and can increase local wind speeds. This area received serious damage during Storm Darwin.

That hurricane looks very very well-developed for a Cat 2 on the latest images... If estimates put it at over 100kt wind speeds, that has to warrant Cat 3 classification (major hurricane)?

Hamlet's Ophelia drowned herself, let's hope this Ophelia will meet its watery death before it reaches Ireland.

The main rain on the western part of the storm. Ireland will be in the main area for the strongest winds.

NHC's update at 4pm is going to be very interesting.

They are the experts at hurricanes. Nearly wish they'd send over a Poseidon to Portugal to get the same level of analysis as they would for a westbound one...because that APERGE shows 190km/h gusts along the south coast.

I wish I knew what that post meant!!

Jesus, this has to downgrade - still have to wait until tomorrow isn’t it, to be in reliable timeframe?

Hooter23

With the Hurricane becoming stronger than expected perhaps the track will move west again as it aprroaches Ireland...

Discodog

I thought that this would be Sunday night into Monday but now seems to be Monday late afternoon. Based on the current estimates when would peak winds arrive in Galway ?

Presumably because we don't have any direct coastal areas? I'm sure parts of Limerick will fare identically or worse to parts of counties with red alerts (I live about 700 meters from the Clare border and high up hill of it so will probably be hit as hard if not harder than the parts of Clare near me). But the more coastal regions of those counties are possibly at risk of worse damage.

Anyone who suggests this will just be another windy day are in for a shock. This is looking like a once in a lifetime event. Its a stronger storm than Debbie in 1961.Be ready and prepared and hopefully it wont be as bad as its looking now.

I have a live Youtube stream set up for the event here in Waterford City. You can also check live data on my website www.waterfordweather.com

Definitely Cat 3.

Looks Close.

Saffir-Simpson Hurricane Wind Scale
Category Sustained Winds
1 74-95 mph 64-82 kt 119-153 km/h
2 96-110 mph 83-95 kt 154-177 km/h
3 (major) 111-129 mph 96-112 kt 178-208 km/h
4 (major) 130-156 mph 113-136 kt 209-251 km/h

Concerned that Red has only been issued for 4 counties in the SW/W (of course likely 11am Monday).
the 'MaxGust' on two models show the SE&E (population dense) getting a fair whack from the Lady round about 4pm Monday.



Dare even say it could more of an Irish Sea storm than an Atlantic Coast?

The UKMO have just a 'yellow' wind warning for Monday (Wales/NI/Scot), will it be another 'Fish' forecast?
Either the models are (both) wrong, or the forecasters...

For those that have a good knowledge, at the moment what's this looking like for West limerick /north kerry

Strangegravy

This is a bit surreal really...

I'm starting to feel nervous about this,I've already told the kids that they're not going to school and they think I'm losing it but I'm really getting a bad feeling about it...hopefully it won't be as bad as its looking at the moment.

Just watching the repeat of the lunchtime weather, you'd hardly guess the windapocalypse was on the way

This shows a very different scenario to Met's red warning, Mayo and Galway not so affected at all in this model

Might be hard to judge the windspeed as the trees are in the distance. Maybe put some wheelie bins of different weight
