    Waterford airport gusted to 46 knots (85 kph) at 17:30. Oak Park max 83 kph.

    Definitely not as severe as expected. The Max at my station of 69km/h was recorded during that spell when Waterford Airport recorded 85km/h. Being near the coast the Airport will always record higher gusts than my Waterford City station.

    Does anyone know the rainfall amount in Galway over the past 12 hours? My guess is less than 5mm.

    It may not of been as bad as expected but thanks to Meteorite ,Syranbruen,G.L, and M.T for all the charts etc throughout the past 24 hours.Its been a very interesting system to watch causing headaches for forecasters. Never saw the TAF's change as much in the past 24 hours.Could of very easily got nasty. Anyway, onto the next one....

    wind was worse for me this morning traveling from maynooth to suncroft,
    rode from suncroft to maynooth this evening at 6pm was not as bad as feared.
    but i think this was due to the change in wind direction it was at my back most of the time,rain wasmore heavy tonight.
    crossing the curragh was the worst on the bike:eek:

    Another non entity 'storm'. This over calling has increased In frequency since the snow storm earlier this year and ophelia last year. Shocking they were considering calling off a european rugby matches for what was nothing more than a bit of wind and rain

    This thread is probably more suitable for talking about things to do with disagreeing with weather warnings. This debate has derailed threads in the past.

    Top gust at standard 10m height was 53mph (85kph) which rolled through just after 5.20pm.

    Here is the last few hours wind graph:

    I think these warning systems need to be looked at, this was not worth a national warning.

    I understand the difficulty that this particular system presented for forecasters but its yet another crying wolf event. Yes it was nasty in a few places, but majority of the population will be wondering what was the hype all about. My worry is that complacency will set in and one day a big storm will come and kill and injure many.

    I really don’t think people understand. A 9 year old girl was injured by a fallen tree. I’m delighted the warnings were called out, could have been a lot worse and met eireann did this perfectly, they updated with all their guidance, made the full country orange when the models showed it and then downgraded when they got clearer information.

    The job of forecaster is to warn people not convince them. If you live in an area that was not affected great for you. I passed 2 trees down blocking 1 side of a road on the way to work, both easily could have cost a life due to being on blind kinks in the road. I would not have gone out thanks to the warning but for I had to. If you or other uninformed people choose to ignore warnings, on your head be it. Do you comment on every thread about attackers on the loose saying " I never been attacked once and the news keeps warning me, people are just going to ignore the warning due to attacker fatigue"?

    Have to agree 100%. Hats off to Met Eireann on this one. They can only go on what the models show them and they reacted perfectly. Its the weather after all, it will do what it wants.

    Remember, 48 hours ago this depression hadn't even started to form yet. To those hurlers on the ditch who like to have a poke at Met Éireann after every storm, I refer you to this famous quote:
    “Consider a rotating spherical envelope of a mixture of gases, occasionally murky and always somewhat viscous. Place it around an astronomical object nearly 8000 miles in diameter. Tilt the whole system back and forth with respect to its source of heat and light. Freeze it at the poles of its axis of rotation and intensely heat it in the middle. Cover most of the surface of the sphere with a liquid that continually feeds moisture into the atmosphere. Subject the whole to tidal forces induced by the sun and a captive satellite. Then try to predict the conditions of one small portion of that atmosphere for a period of one to several days in advance.” – Author Unknown

    In any case, I think the orange level storm warning was essentially for rainfall potential and it was added that some coastal areas would see orange alert conditions met for wind, nobody was ever expecting wind gusts to reach orange level in most counties, and the storm was complex for rainfall forecasting with different output on different models, all showing some areas likely to exceed 30 mm. At some point I made the comment that it might go from yellow to orange and they might as well do a country-wide orange since at least some places in each county might reach orange alert status. The local rainfall minimum right over Galway combined with probably the lowest wind speeds achieved made it a definite bust in Galway but then I don't recall anyone saying in advance "this looks really bad for Galway," maybe if you'd suggested some place it wouldn't be that bad, you would have gotten that suggestion -- storm warnings tend to concentrate on what could happen and where it could be worst, to some extent, the storm verified on those considerations if maybe a little underwhelming on both counts. Probably whoever was out at Kinsale energy platform thought highly of the warnings they received anyway.

    Peak gust that I can see on the Welsh side past few hours would be 128 km/hr at Aberdaron at 19z. At the same time, 115 km/hr at Pembrey Sands in southwest Wales.

    In the end the strongest winds stayed further out to sea , pressure gradient did not tighten as much as earlier predicted. The guidance from the various models showed very severe weather as close as late last night and they backed off from this in stages in the earlier hours and through the morning. Right at the end the models got it fairly right.

    In hindsight the French models did well, they seemed to be under predicting the speeds and track compared to the other models but were on it first I reckon , ECM got there, HIRLAM got there, ICON bit over done the wind speeds but adjusted well in the end, FMI - HIRLAM last to adjust downwards in speed and track. GFS and WRF were struggling with this , WRF -NMM did best in the end if under doing the speeds .

    Squally in the afternoon but wind not a problem here near Tralee, gusting to about 60 km/h . 15mm of rainfall .

    Bar dropped to 982.5 hPa at 12.03 , High 1001.3 at 0.00 currently 997.7 hPa Rising Rapidly

    These seem to be the standard rules for storm threads:

    1. Whatever actually happens, somebody will say it missed them completely and should never have been called a storm.

    2. Whatever actually happens, somebody will say it was the worst they ever saw and feel lucky to be alive.

    3. In rare instances, somebody claims both 1 and 2, confusing the readers even more.

    4. Whatever was actually forecast, somebody will say Met E did a perfect job forecasting it, hats off to them.

    5. Whatever was actually observed, somebody down the road will report it was totally different there (and probably it was, winds can be blocked out by buildings or hills, and showers can be heavy one place, light a few kilometres away).

    So in general when assessing how any given storm went, you have to count up how many of each of these sorts of posts there were, the excess of 2 over 1 can be taken as a rough guide to storm severity, the percentage of posts resembling 4 will always be about the same, I think if there was a totally unpredicted catastrophe of stupendous proportions, or a dead calm throughout a red alert, somebody would post this anyway.

    Hope nobody takes offence, by the way, just my somewhat facetious view of storm threads past, present and no doubt future.

    On a more serious note, I think Meteorite does a great job stocking these storm threads with useful content and I really liked to see the post-storm recap above.

    This probably lacked one ingredient to make it a very powerful windstorm, and that was a tighter supporting gradient at mid to upper levels, I think (storm) Deirdre did the best with what she was given.

    The reason this storm went wrong and didn't do as ME said it should was that "our" Joanna was off partying and Galavanting last night (according to her tweets) when should have been in Glasnevin.

    Some will ask where's the Harm in that?...well he wasn't out partying as far as I can see :D

    I'll get my hat and brollie if it's not too windy somewhere;)

    I’m always in the “glad it didn’t turn out as bad as forecast “ brigade


    But it’s always always better to be safe than sorry imo
    I secured everything outside the morning as per usual
    It took 5 minutes
    It looks like it wasn’t necessary now but who cares !

    Keep up the good work it is appreciated

    Well the wind this evening was short lived, but strong enough I was happy to have made the call not to bring the kids to the flicks and go DVD instead here in Wicklow. Particularly given the flooding. Strong enough to damage the roof of one of the sheds anyway, so that's my Sunday morning lie on gone!

    The more dramatic impact today was rain rather than wind and I think given the flooding in some areas the warning was definitely warranted.

    They're very dynamic systems in the Atlantic and it was very possible that there could have been much higher winds in areas of the south of the country.

    The over hyping often isn't anything to do with Met Eireann, rather it's certain commentators and tabloids over dramatically interpreting things. All of a sudden a measured weather forecast and alerts ends up as Armageddon.

    Was a weird storm, took the dog out for a walk around 7 ish thinking it grand, after that it kicked off. Was very quick that it took hold. Loads of branches down around the house. Thanks to all that saw this. Hope all survivied it. Not as bad as it was forecasted but still rough enough. I still heeded the warnings and stayed indoors. Now to fix that big tree that fell in the garden, might be free wood but I kept the dog in all night. Glad I did!

    Lovely to wake after a little sleep earlier to see a half moon smiling serene above the cowsheds.

    Then sweet silence and more sleep.

    Rest after rumpus!

    No harm ever came of taking care. A lot of harm comes from not taking care.

    So now our fair earth will soak up the excess water against summer needs. And more this week...

    Happy Sunday..

    What I found fascinating about this storm was the two wind features in Cork. A direct southerly, that the models I feel underplayed, then an hour of utterly eerie calm before the second lot of much stronger westerly winds came in; which were further out at sea than expected so not too bad but still quite strong.

    I was watching the whole thing, and I felt safe enough to help my 72 year old father up the ladder onto the roof in the hour gap to secure a rope to a wind turbine that had broken. Boards told me roughly where the sudden ramp up in winds were as any time (Tralee, Cork etc) so I felt completely safe doing this. (And before anyone asks he would not let me go up on my own, he had to come too).

    We then went up to the loft and within 5 minutes of being up there it whipped up a mad one, but only because I was watching the models and boards carefully, I knew roughly when it was all going to happen. These little intricacies most people wouldn't understand or care about, hence throw up a warning colour and adjust as necessary.
