    eh northside of cork city. it's grand, no where near as bad as last week


  • Registered Users Posts: 11,880 ✭✭✭✭Rock Lesnar


    Wind has died considerably here in the last 30mins but the rain is fairly heavy and persistent.


  • Closed Accounts Posts: 1,027 ✭✭✭MidMan25


    It's wild here in East Cork!

    Some very strong gusts.


  • Registered Users Posts: 651 ✭✭✭Blackdragon

    After calming down now thankfully, rain stopped too.

    Absolutely horrific in West Wales, strong winds all evening and night accompanied by torrential rain. Supposed to be getting ferry home from Fishguard at lunchtime, looks very unlikely given tonight's ferry crossing was cancelled, gutted :(

    before everyone goes into meltdown over that chart, the isobars on it are at 1 hectopascal intervals, most of what we see are 4 Hpa, so there's 4 lines on this for every line we'd normally be used to seeing

    That said, the centre pressure is very low, and if that track works out, it WILL be a wild period for pretty much all of the country, with a brief period of calm in the far north as the centre passes over. it will also be a daytime storm, so the potential for disruption and injury will be higher, people will be on the move for a normal working day, deferring or delaying travel will not be the option that it was over Christmas.

    It will be one to watch, that's for sure.

    Shore, if it was easy, everybody would be doin it.😁

    Yep if that chart where to verify ( HIGHLY UNLIKELY at this range we all should know ) it would warrant another level 3 alert.

    None of the models agree about next Sunday/Monday. I'm putting the 3 charts here & going to come back next weekend & see which is closest & that's the one I'm going to trust the most for the rest of the winter for FI ;)

    I'm doing some snow dancing. The storm gods have had their day. They can go packing south, let the polar air-mass flood over us.

    All clear and sunny now but next front/trough visible now over the Atlantic http://www.sat24.com/ bringing tonight/tomorrow mornings weather to us.

    Not sure how much I can trust a GFS model for 168h (7 days) ahead. IIRC it was pretty good at predicting the big storm we had last week, a week ahead.

    From out there on the moon, international politics look so petty. You want to grab a politician by the scruff of the neck and drag him a quarter of a million miles out and say, ‘Look at that, you son of a bitch’.

    Assume you made it fine, as I'm sitting on it now :) I was surprised last night to see they'd cancelled some crossings as over in Hampshire it was calm. This ferry is rocking up and down a fair bit, but it's like crossing a pond compared to last monday!

    I wouldn't trust it at all, but it's an example of the kind of stuff coming up on the models. It's unlikely it will come off like that, but another variation of it might since we are now in a pattern with low pressure systems passing close to or over Ireland.

    Hope it's not too bad, tis my babygirls 18th birthday on the 6th and we have had blizzards, ice, torrential rain amongst others in the past, to the point where we have considered moving it to the summer! :P

    12Z UKMO shows some windy weather during Thursday-Friday with this low crossing us from the southwest.

    UW72-21.GIF?30-17
    UW96-21.GIF?30-17

    12Z GFS for the same time doesn't look as clean, has a more complex large area of low pressure in the Atlantic with several centers spinning around.

    gfs-0-75-3h.png?12

    Then later on the 6th, 12Z GFS is similar to the 06Z showing a large around of low pressure, though this time it has matured earlier and it's not as stormy over Ireland. 150+ hours away so not much point looking at it in detail yet anyway.

    Uh oh.

    A note at the end of the latest ME forecast...

    N. B. Given the highly changeable and often wet conditions that are likely to prevail across Ireland for the coming week, and the fact that all lands are either saturated or waterlogged, the probability of river flooding will increase in many areas. In addition, the turn of the year will bring maximal high tides which, in combination with strong onshore winds, high seas and possible surge effects, will predispose many coastal districts to maritime inundation.


  • Registered Users Posts: 11,134 ✭✭✭✭maquiladora


    12Z GEM also showing that low on the 5th/6th.

    ECMWF also has that small system to the southwest @ 72hrs.

    One to watch for sure.

  • Registered Users Posts: 14,327 ✭✭✭✭M.T. Cranium


    Looking at 96h ECM and other models with more frequent hours, that intense low tracks northeast across the country overnight 2-3 Jan.

    Across the entire model suite, we are looking at two very strong windstorms on the 3rd and 5th-6th.

    The first of these looks as though it may cut northeast at the last possible moment, exposing the south and east to the ideal track for very strong south to southwest gusts (late overnight to mid-day Friday 3rd roughly).

    The second storm resembles the recent 26th-27th event for track and intensity. Exceptionally cold air pouring off the North American continent around then would be fuelling the low as it develops in the central Atlantic on the 4th.

    While these are two major peaks in wind speed, the entire period looks windy and as the Met service have noted, very high tidal values on the 1st will not be dropping off that quickly so that any strong winds on the 3rd in particular will have almost the maximum tidal range as support for coastal problems. (Moon is new and also at perigee on the first of January)


  • Registered Users Posts: 11,134 ✭✭✭✭maquiladora


    Looking at the ECM on the weather underground 6-hour interval charts, the first low has already begun to weaken by the time it gets close to us and ends up giving the west coast a brush of gales but nothing too severe.

    Timing/track changes will make all the difference though.

    Strong enough gusts here in South east Kerry at the moment.


  • Registered Users Posts: 20,340 ✭✭✭✭Rikand


    She's getting windy out there!


  • Closed Accounts Posts: 6,720 ✭✭✭Sir Arthur Daley


    Storm picking up here in the south west.

    Today in Mallow


  • Registered Users Posts: 10,064 ✭✭✭✭Oscar Bravo


    Cant fault Met Eireann for detail in their 2227 update tonight

    Mostly cloudy tonight with heavy rain moving in across the country from the Atlantic (scattered thunderstorms in the west and southwest). The rain will turn heavy and persistent for a time overnight, with the risk of spot flooding. Becoming rather windy for time too, with strengthening southerly winds. A clearance to scattered showers will follow later and winds will veer southwest and moderate. Milder at first, but turning cooler with the clearance. Lowest temperatures of 2 to 4 degrees Celsius, with a touch of grass frost locally towards dawn.
    hr.gif

    Tomorrow

    Tuesday will start mainly dry with sunny spells, but showers will soon develop in the west and southwest will gradually spread to other parts during the day. Some of them will merge into longer spells of rain and a few heavy bursts are likely. Southerly winds will increase again and it will become blustery for a time, especially near south coasts. Cool, with highest afternoon temperatures of between 5 and 8 degrees, coldest in the north. Becoming drier for a time in the evening with clear spells, but further showers feeding into Atlantic counties then.

    Outlook

    OUTLOOK: Changeable and unsettled for the rest of the week, as low pressure in the nearby Atlantic steers in bands of wet and windy weather.
    Cool if not cold by by day, and chilly by night - frost on some of the nights.

    TOMORROW NIGHT: Most areas will dry with clear spells - scattered showers occurring too (mainly in the south to begin and later in the night near Atlantic coasts). Cold, with a slight to sharp frost, and the risk of some icy stretches. Lowest temperatures 1 to 4 degrees Celsius, with light to moderate southwest breezes.

    THURSDAY: Breezy to begin with fresh to strong and gusty southwest winds. Holding mostly dry for daylight hours across much of the eastern half of the country with some sunny spells, but scattered showers across the rest of the country. Wet and windy weather likely to move in across the country from the west later on in the evening. Highest temperatures 6 to 10 degrees Celsius, with strong and gusty southerly winds later. Staying windy overnight, with further spells of rain.

    FRIDAY: Windy with strong southwest winds. Heavy showers, merging to longer spells of rain (threat of hail or thunder later). Showers will be more scattered to the southeast and east, with longer drier spells occurring in these areas (some sunny spells too). Cool, with highest temperatures of just 6 or 7 degrees Celsius. Showers will tend to retreat to coastal counties of the west and northwest after dark with winds easing. Cold with a widespread sharp frost, some icy stretches too. Lowest temperatures - 2 to +2 degrees Celsius, with light to moderate southerly winds.

    SATURDAY: Some uncertainly for the weekend, but heavy persistent rain likely to move up from the south of the country on Saturday, last to arrive in Ulster (possibly turning wintry over higher ground in the west and north later). Highest temperatures 3 to 7 degrees Celsius (coldest across the western half of the country).

    SUNDAY: Overnight rain clearing away eastwards and winds easing; fair but cold weather for much of the day thereafter.


    N. B. Given the highly changeable and often wet conditions that are likely to prevail across Ireland for the coming week, and the fact that all lands are either saturated or waterlogged, the probability of river flooding will increase in many areas. In addition, the turn of the year will bring maximal high tides which, in combination with strong onshore winds, high seas and possible surge effects, will predispose many coastal districts to maritime inundation.

    I hate to disagree with you Maq (first time! I always agree with you) & bnt but I think the GFS did a good job a week out from the 26th/27th. It may have had a crazy low (905) 8 days out that fell back but at least we knew there was something coming. We'll see if it got it nearly right around a week from now...

    Only fault I'd have is the day they missed, does Wednesday not exist or are they taking New Years Day off :D

    Looks like flooding more so than the wind could be the topic this week
