⚠️ Storm Éowyn - Fri 24.01.25 (**Please read Mod Instruction in OP.**)

An RTE documentary on the 175th anniversary of the Night of the Big Wind, 2014. Eddie Lenihan blames the fairies.

Harmonies further South, worst winds across Kerry and Cork!!

Feck, looks like we'll miss it and France will get all the fun

Tomorrow morning will definitely see a nationwide orange warning issued and Amber for Northern Ireland. I don't think they will hold of until Thursday to issue red warnings especially with what we are looking at. Red warnings will follow tomorrow for some parts of the west and northwest I think. There will be close contact between Met Eireann and the UK Met Office over the last few hours and days ahead. Met office UK referred to Ireland alot in there update this evening also.

Met Eireann have already stated they will issue warnings at around 11am. That will give them ample time to process the overnight runs. I think a Nationwide red is more likely but obviously depends on the 0z runs. What's even more likely is that NI will go red

A summary of the latest output from the primary weather models for Storm Eowyn:

• There is concensus for the storm system to track northeasterly toward the northwest coast of Mayo between 4am and 7am on Friday morning.
• The strongest winds will be immediately to the south of the storm centre as it tracks northeast. However, the windfield will be large which means the potential for disruption pertains to the entire island of Ireland.
• The UKV and ICON models brings the storm centre over land in the NW Mayo and Donegal
• The northeasterly progress of the storm system on the ECM is much slower than on other models, which would result in a longer period of sustained winds.
• The ICON clears much quicker than any other model later Friday AM. In fact, it can't wait to get of here after breakfast time on Friday.
  

I will not be going into likely max wind mean or gust speeds as they differ from model to model, and there is enough colourful charts being shared elsewhere without more being posted to add to the confusion.

Right now it's about determining the likely track and depth of the storm.

The deep cold in the deep south of the USA is serving to fire up the jetstream which is energised as it wraps are around the cold airmass and is flung like a slingshot across the Atlantic. Storm Eowyn is only just forming in the Gulf of Mexico (or Gulf of America if you prefer...) as a shortwave before undergoing rapid cyclogensis later tomorrow night and through Thursday. We will get a clearer idea of expected wind speeds this time tomorrow and during Thursday.

Met Éireann says "Western and northwestern counties are likely to see status orange wind warnings as a minimum."

Weather warnings are likely to be issued during Wednesday.

Keep an eye on Met.ie for the most accurate and up to date information.

MO predicting 150kph gusts in Mayo and 140kph in Galway, only 60kph sustained winds though, all on friday AM.

Dublin much weaker at 105kph gusts and 45kph sustained.

Low centre out to the West.

Winds impacting Kerry & Cork alright (to start with).

The storm warrants red on its own merit. The timing does indeed add to its seriousness. I would think the Taoiseach will appeal to everyone to take shelter until about lunchtime Friday!

Anyway let’s hope there are downgrade. I don’t want them for snow but wind I do. I hate wind storms.

Five to midnight forecast on RTE Radio 1 coming up.

We can always go to mass.

Harmonie 21z, just out. For those wanting to leave the South out of the red warnings, think again
