Nuashonraithe Dé Máirt, an 9 Nollaig 2025, i bhfeidhm go dtí go bhfógrófar a mhalairt.
Beidh gaotha láidre agus báisteach throm ar fud na hÉireann ó oíche Dé Luain, an 8 Nollaig, agus i rith Dé Máirt, an 9 Nollaig, mar gheall ar chóras lagbhrú, ar thug Met Éireann an t-ainm Stoirm Bram air.
Tá Met Éireann ag déanamh monatóireacht ar chóras Atlantaigh atá ag forbairt agus a gceaptar go mbeidh gaotha láidre, leibhéil arda uisce feadh an chósta, agus tréimhsí de bháisteach throm dá bharr ar fud na hÉireann ó go déanach oíche Dé Luain (an 8 Nollaig) agus i rith Dé Máirt (an 9 Nollaig).
Tar éis seachtain de bháisteach leanúnach, tá na hithreacha ar fud na tíre an-sáithithe cheana féin agus tá go leor aibhneacha ag druidim le leibhéal lán a mbruach. Dá bhrí sin, is dócha go mbeidh tuilte dromchla agus tuilte abhann mar thoradh ar aon bháisteach bhreise ar an Máirt agus, b’fhéidir, sna laethanta ina dhiaidh sin.
CÉN FÁTH AR AINMNÍODH Í?
Tá Met Éireann ag déanamh faireacháin ar an gcóras seo le roinnt laethanta anuas. Cé gur córas neamhsheasmhach é agus nár fhorbair sé go hiomlán tráth a ainmniúcháin, is léir go mbeidh tionchair chomhcheangailte aige i roinnt contaetha i rith an lae, Dé Máirt, an 9 Nollaig, de bharr idirghníomhú na ngaoth láidir, na báistí agus na lánmhara comhthráthacha. Ainmníodh an stoirm mar gheall ar éifeacht na ngaoth láidir ar limistéir chósta ag am lán mara, chomh maith leis an mbáisteach throm a thitfidh ar ithreacha atá sáithithe cheana féin, rud a mhéadóidh an baol tuilte.
Deir an meitéareolaí Matthew Martin:
“Tá sé ag éirí níos dóichí anois go mbeidh aimsir an-gharbh ag Éirinn ó oíche Dé Luain agus i rith Dé Máirt. Rachaidh córas lagbhrú san Atlantach i ndianú go measartha tapa agus é ag druidim leis an gcósta thiar theas oíche Dé Luain. Ar dtús beidh tréimhse de bháisteach throm ann sula bhforbróidh limistéar de ghaotha an-láidre. Tá éiginnteacht fós ann maidir le rian agus déine an chórais, ach is dócha go mbeidh tionchar suntasach aige i gceantair áirithe, go háirithe i limistéir chósta an deiscirt, an iarthair agus an iarthuaiscirt.
Mar gheall ar nádúr athraitheach an chórais, tá rabhadh gaoithe buí eisithe againn don tír ar fad, agus ina dhiaidh sin sraith rabhadh gaoithe oráiste do chontaetha cósta an deiscirt agus an iarthair, ós iad sin is leochailí i leith thionchair chomhcheangailte na gaoithe ag am lán mara. Tá rabhadh báistí buí eisithe againn freisin do Cheatharlach, Chill Chainnigh, Loch Garman, Corcaigh, Ciarraí, Tiobraid Árann agus Port Láirge. Molaimid, áfach, do gach duine súil ghéar a choinneáil ar réamhaisnéisí agus rabhaidh Met Éireann, mar is dócha go n-athróidh an scéal de réir mar a bheidh níos mó cinnteachta ann faoi rian agus am an chórais.”
Lean Matthew air:
“Táthar ag súil le tionchair tuilte mar go dtitfidh an bháisteach ar ithreacha atá sáithithe cheana féin agus go bhfuil go leor aibhneacha ag druidim le leibhéal lán a mbruach faoi láthair. Táimid i dtréimhse lán mara réalteolaíoch, a bheidh ag teacht leis na gaotha láidre, a bheidh ag séideadh isteach ón bhfarraige i gceantair áirithe, agus dá bhrí sin tá baol ard tuilte cósta ann. Aithnímid agus athdhearbhaímid an seanchomhairle aitheanta ó Gharda Cósta na hÉireann: “Fan Siar, Fan Ard, Fan Tirim”.
Cuirfidh an lánmhara cosc ar aibhneacha draenáil amach chun na farraige, rud a mhéadóidh go suntasach an baol tuilte suas an abhainn i limistéir ísle. Ba cheart don phobal aird a thabhairt ar threoir a n-údarás áitiúil agus na seirbhísí éigeandála ina gceantar.”
AN SCÉAL MEITÉAREOLAÍOCH
Tá sé tuartha go rachaidh lagbhrú Atlantaigh atá ag dul i ndianú gar d’Éirinn oíche Dé Luain agus Dé Máirt.
Neartóidh gaotha an deiscirt chun tosaigh ar an gcóras oíche Dé Luain, agus d’fhéadfadh séideáin ghaoithe an-láidre tarlú, go háirithe feadh chóstaí sceirdiúla an Atlantaigh. Leanfaidh na gaotha láidre ar aghaidh i rith Dé Máirt, ag casadh ó dheas go dtí an t-iardheisceart agus ansin siar de réir mar a théann an lá ar aghaidh. Titfidh báisteach throm go déanach Dé Luain go maidin Dé Máirt ar ithreacha atá báite in uisce cheana féin, rud a mhéadóidh an rith chun srutha agus a chuirfidh dlús leis an tionchar atá ag aibhneacha.
Tá leibhéal measartha muiníne fós ann maidir le rian agus déine bheacht an chórais; d’fhéadfadh athruithe beaga ar a chonair tionchar suntasach a imirt ar dhéine na n-iarmhairtí. D’fhéadfadh athrú beag ar chonair an chórais tionchar a imirt ar na séideáin ghaoithe is láidre, ar uainiú na ngaoth is treise agus ar mhéid na dtionchar cósta. Leanfaidh Met Éireann de dhianfhaireachán a dhéanamh ar an gcóras agus nuashonróidh sé na rabhaidh de réir mar is gá.
Fíor 1: An réamhaisnéis is déanaí ó shamhail ECMWF maidir le suíomh an ísealbhrú ag meán lae Dé Máirt (an 9 Nollaig), mar a bhí tráth foilsithe Dé Luain an 8 Nollaig. D’fhéadfadh athruithe teacht air.
RABHAIDH AGUS TIONCHAIR:
Braithfidh déine na ngaoth agus a dtionchair ar an idirghníomhú idir an t-ísealbhrú agus an scairdsruth. Mar threoir maidir leis na tionchair fhéideartha, tá na rabhaidh seo a leanas eisithe ag Met Éireann (amhail an 7 Nollaig tráth foilsithe):
Foláireamh Báistí Buí do chontaetha an deiscirt, áit a bhfuiltear ag súil go dtitfidh báisteach throm ar ithreacha atá sáithithe cheana féin, agus go bhfuil go leor aibhneacha sa deisceart ag druidim le leibhéal lán a mbruach tar éis seachtain de bháisteach leanúnach.
I measc na dtionchar a bhfuiltear ag súil leo i rith Dé Máirt (fiú má théann an rabhadh báistí in éag maidin Dé Máirt) tá:
- Tuilte dromchla agus tuilte abhann i rith an lae Dé Máirt agus, b’fhéidir, Dé Céadaoin freisin, mar go bhféadfadh sé tamall a ghlacadh ar na haibhneacha freagairt don bháisteach. Cuirfidh an lánmhara comhthráthach cosc ar uisce na n-aibhneacha sreabhadh amach chun na farraige, rud a fhágfaidh go mbeidh uisce ag carnadh siar agus a mhéadóidh go suntasach an baol tuilte suas an abhainn i limistéir ísle, go háirithe feadh aibhneacha i gCorcaigh, i ndeisceart Chiarraí, i ndeisceart Thiobraid Árann agus i bPort Láirge.
- Dálaí taistil deacra.
- Cur isteach ar ócáidí taobh amuigh.
Foláireamh Gaoithe Buí don tír ar fad i rith Dé Máirt, agus Foláireamh Gaoithe Oráiste do chontaetha éagsúla ag amanna éagsúla i rith an lae, mar gheall ar ghaotha an-láidre go gaotha de neart stoirme ón deisceart, agus na gaotha is láidre feadh an chósta.
Áirítear ar na Tionchair Fhéideartha iad seo a leanas:
- Dálaí taistil an-deacair: D’fhéadfadh go mbeadh dálaí contúirteacha tiomána agus moilleanna a chruthú ar bhóithre agus moill a chur ar sheirbhísí iarnróid, farantóireachta agus aeir, mar gheall ar uisce ar dhromchla bóithre, infheictheacht laghdaithe agus gaotha láidre. Cuir am breise in áireamh don turas agus bí cúramach ar bhealaí sceirdiúla.
- Tuilte i limistéir ísle chósta: Méadóidh an teaglaim de ghaotha láidre ón deisceart ag séideadh isteach ón bhfarraige, lánmhara réalteolaíocha an-arda agus gníomhaíocht tonnta an baol tuilte cósta. Táthar ag súil go sroichfidh borradh stoirme suas le 0.8 m i roinnt áiteanna agus go mbeidh tonnta suntasacha ann. Is dócha go mbeidh tuilte cósta ann, go háirithe ag am lán mara agus i limistéir ísle sceirdiúla. Beidh lán mara ar chóstaí an deiscirt agus an iarthair go luath maidin Dé Máirt (idir 7am agus 9 am), agus beidh sé gar do 2am. ar chóstaí an oirthir. “Fan Siar, Fan Ard, Fan Tirim”.
- Scaileogú: D’fhéadfadh tonnta móra dul thar bhallaí farraige nó cosaintí cósta, rud a chruthódh baol do dhaoine gar don chósta agus a d’fhéadfadh damáiste a dhéanamh do bhonneagar cósta in áiteanna sceirdiúla.
- Crainn tite, smionagar agus rudaí scaoilte: D’fhéadfadh gaotha láidre rudaí nach bhfuil daingnithe a thógáil leo, rud a mhéadódh an baol damáiste agus guaiseacha ar bhóithre agus in áiteanna poiblí.
- Cur isteach ar imeachtaí faoin aer: D’fhéadfadh na coinníollacha aimsire moilleanna, cealuithe nó an gá le bearta sábháilteachta breise a chruthú d’imeachtaí agus do ghníomhaíochtaí faoin aer.
D’fhéadfaí na rabhaidh a nuashonrú de réir mar a dhéanfar anailís ar rithí nua na samhlacha agus de réir mar a mhéadóidh an chinnteacht. Chun na sonraí is déanaí faoi na rabhaidh a fháil, féach ar Rabhaidh & Comhairle – Met Éireann – Seirbhís Náisiúnta Mheitéareolaíochta na hÉireann

WHY AND HOW ARE STORMS NAMED?
Storms are named when they could cause ‘medium’ or ‘high’ impacts in one of the three partner countries. This enables consistent, authoritative messaging to the public and other stakeholders to help them to prepare for and stay safe during potentially severe weather events.
Since 2015, Met Éireann and the UK Met Office have been working together on the naming programme and were joined by the Netherlands’ KNMI in 2019, to form the ‘western group’ of European weather services.
When a storm is forecast, the national weather service that expects the biggest impact from the severe weather to hit its region, or is likely to be first affected by it, names the storm. Storm naming happens in conjunction with orange/red weather warnings, which could be for wind, rain or snow, or a combination of these conditions. Those warnings are, in turn, issued based on a combination of numerical thresholds and the potential impacts foreseen.
CONAS A ROGHNAÍTEAR AINMNEACHA STOIRMEACHA?
Don séasúr 2025/26, chuir gach ceann de na trí sheirbhís meitéareolaíochta seacht n-ainm leis an liosta séasúir. D’iarr Met Éireann ar mhuintir na hÉireann a rogha ainmneacha a chur isteach trí fheachtas ar na meáin shóisialta. Fuarthas níos mó ná 10,000 ainm ó 4,137 duine den phobal.
Is iad seo a leanas an liosta iomlán do shéasúr 2025/26: Amy, Bram, Chandra, Dave, Eddie, Fionnuala, Gerard, Hannah, Isla, Janna, Kasia, Lilith, Marty, Nico, Oscar, Patrick, Ruby, Stevie, Tadhg, Violet, Wubbo.

STOIRMEACHA NA HÉIREANN I MÍ NA NOLLAG:
Tá sé an-choitianta go mbíonn stoirmeacha ainmnithe in Éirinn i rith an gheimhridh, go háirithe i mí na Nollag. Anuraidh ag an am seo, chuaigh Stoirm Darragh i bhfeidhm ar Éirinn, agus gach bliain seachas bliain amháin ó cuireadh tús leis an tionscnamh ainmniúcháin, bhí stoirm ainmnithe againn i rith mhí na Nollag.
Fíor 3 go 17 Stoirm ainmnithe i mí na Nollag i bhfeidhm ar Éirinn ón Máirt, an 1 Meán Fómhair 2015 go dtí Stoirm Bram.
Is iad seo a leanas na cúig luas gaoithe marthanaí is airde a breathnaíodh in Éirinn i mí na Nollag:

PAST STORM SEASONS OVERVIEW
- In the past season (2024/25), there were six named storms affecting the area, starting with Ashley (October 2024), Bert, Conall, Darragh, Éowyn and closing with Floris (August 2025). All of these storms were named by the Western Europe Group of National Meteorological Services, formed by the UK Met Office, KNMI and Met Éireann.
- The highest number of named storms in a season, affecting Ireland, is fourteen (14), in 2023/24. Two of these storms (Elisa and Geraldine) were named by the Southwestern Europe Group (France, Portugal and Spain). The lowest number of named storms, affecting Ireland, since the initiative began, was four, in 2022/23.
- On average, there have been around eight named storms each season since the storm naming initiative began in 2015.
- 2015/16 remains the season with the greatest number of storms reaching storm force 10, when nine of the 11 named storms observed storm force 10 or higher sustained wind speeds at coastal stations.
- Last season 2024/25, four (of the six) named storms observed storm force 10 or higher sustained wind speeds on land in Ireland:
- Ashley on Sunday 20th October 2024, with gusts up to 137 km/h (Storm Force).
- Bert on Saturday 23rd November 2024, with gusts up 115 km/h (Storm Force).
- Darragh on Friday 6th December 2024, with gusts up to 141 km/h (Violent Storm Force).
- Éowyn on Friday 24th January 2025, with gusts up to 184 km/h (Hurricane Force).
- Prior to Storm Éowyn, the last hurricane force winds observed on land for Ireland were during Storm Darwin on Wednesday, 12th February 2014, when gusts reached up to 159 km/h.
- During Storm Éowyn, a gust of 184km/h was recorded at Mace Head Co. Galway on 24th January 2025. This is provisionally the strongest gust speed ever recorded in Ireland, breaking the previous record of 182km/h set at Foynes, Co. Limerick in 1945.

Issued on 7th December 2025, valid until further notice
A deepening Atlantic low-pressure system will impact Ireland on the night of Monday 8th December and during Tuesday 9th.
Met Éireann is closely monitoring a developing Atlantic system with the potential to bring very strong winds, high coastal water levels, and periods of heavy rainfall to Ireland from late Monday night (8th December) through Tuesday (9th December).
After a week of persistent rain, soils across the country are already highly saturated and many rivers are approaching bank-full conditions, so any additional rainfall is likely to result in surface and river flooding on Tuesday and possibly during following days.
Meteorologist Matthew Martin, says:
“It’s looking increasing likely that Ireland will experience some very inclement weather from Monday night and through Tuesday. A low-pressure system in the Atlantic is going to deepen fairly rapidly as it approaches the country on Monday night. Initially there will be a spell of heavy rain before a swathe of very strong winds develop. There remains a good deal of uncertainty in the track and intensity of the system, but it has the potential to be an impactful event. Given its evolving nature, we have issued a yellow wind warning for the entire country which will be updated when certainty increases, as well as yellow rainfall warnings for certain areas, and we encourage everyone to check in regularly with Met Éireann’s forecasts and warnings.
Flooding impacts are expected as the rain will fall on already saturated ground and many rivers are currently approaching bank full conditions. We are in a period of high astronomical tides, which will coincide with the strong, potentially onshore winds, so coastal flooding is likely. We echo the well-known advice of the Irish Coast Guard: “Stay Back, Stay High, Stay Dry”.
The high tides will prevent the rivers from discharging to the sea, significantly increasing the risk of upstream flooding along low-lying areas. People should refer to the guidance of their local authorities and emergency responders in their area.”
METEOROLOGICAL SITUATION
A deepening Atlantic depression is forecast to track close to Ireland on Monday night and Tuesday.
Southerly winds ahead of the system will strengthen on Monday night, with periods of severe wind gusts possible, especially near exposed Atlantic coasts. The strong winds will continue through Tuesday, veering southwest to west in direction during the day. Heavy rainfall late Monday into Tuesday morning will fall over ground that is already water-logged, increasing runoff and river response times.
The system hasn’t developed yet (as of Sunday afternoon). Confidence remains moderate regarding the exact track and intensity of the system; small shifts will influence the severity of impacts. A slight shift in the system’s path could influence peak wind gusts, timing of strongest winds, and the extent of coastal impacts. Met Éireann will continue to monitor the system closely and update warnings as required.
Fig. 1: A current model prediction of the position of the low-pressure system at midday on Tuesday (9 December) and the forecast mean wind speed in knots
WARNINGS AND IMPACTS:
The intensity of the winds and their impacts will depend on the interaction of the low with the jet stream, but as a mean for awareness of the potential impacts, Met Éireann has issued the following warnings (on 7th December at time of publication):
A Status Yellow rain warning across southern counties, with heavy rain expected to fall on already saturated ground and with many rivers in southern regions approaching bank full conditions after a week of steady rain.
Expected impacts, throughout Tuesday (even if the rain warning will expire on Tuesday morning) are:
• Surface and river flooding, through the whole day Tuesday, even if the rain warning will expire on Tuesday morning, as the rivers may take time to respond. Coinciding high tides will prevent river water from discharging to the sea, causing water to back up and significantly increasing the risk of upstream flooding along low-lying areas, especially across rivers in Cork, south Kerry, south Tipperary and Waterford.
• Difficult travel conditions
• Potential disruption to outdoor events.
A Status Yellow wind warning for Ireland all day Tuesday, due to very strong and gusty southerly winds expected, and the possibility of gales near coastal areas.
Expected impacts include:
• Difficult travel conditions: Surface water, reduced visibility, and strong winds may make driving hazardous and could lead to delays on roads, rail, and ferry services. Allow extra time and take caution on exposed routes.
• Flooding in low-lying coastal areas: The combination of the southerly, onshore winds with very high astronomical tides and wave action will heighten the risk of coastal flooding. Surge levels will rise to 0.8m in some locations and significant waves are forecast. Coastal flooding is likely, particularly during high tide times and in exposed low-lying areas. High tide on western and southern coasts is early Tuesday morning (7-9am), whilst time of high tide is close to 2pm on eastern coasts. “Stay Back, Stay High, Stay Dry”.
• Wave overtopping: Large waves may breach sea walls or coastal barriers, posing risks to people near shorelines and potentially impacting coastal infrastructure in exposed locations.
• Debris and loose objects displaced: Strong winds could lift unsecured items, increasing the risk of minor damage or hazards on roads and in public spaces.
• Outdoor events impacted: Weather conditions may lead to delays, cancellations, or the need for additional safety measures for outdoor activities.
The warnings may be updated as new model runs are analysed and certainty increases. For all warnings details, please check Warnings & Advisories – Met Éireann – The Irish Meteorological Service
HOW TO STAY SAFE IN SEVERE WEATHER – BE WINTER READY
Stay informed & plan ahead:
Stay up-to date with the forecast and the warnings for your county on met.ie, the Met Éireann app or Met Éireann socials (@meteireann).
- Check in with your local authority and emergency management stakeholders (Irish Coast Guards, Gardaí, etc) via their websites and social channels on road closures, flooding updates, and community alerts.
- Allow for disruption during Tuesday morning commute.
- Plan extra travel time and reduce speed.
- Expect surface water, debris and poor visibility on Tuesday morning.
- Check in with neighbours, older people or anyone who may need assistance in case conditions worsen.
Be aware of elevated flood risk and high winds:
- Ensure your mobile is phone is fully charged to enable communication in advance of the event and keep local emergency numbers in your phone.
- Take care on exposed roads and bridges.
- Watch for fallen branches and debris.
- Allow extra time for your trip and if you are driving a high sided vehicle, try to anticipate exposed sections of roadway where winds will be stronger.
- Secure loose outdoor items ahead of strengthening winds.
- ESB Networks is highlighting the dangers posed by fallen live wires and is advising the public and the emergency services to stay away from these fallen cables and to report such cases to it immediately. ESB Emergency Services can be contacted at 1800 372 999.
- Stay back from riverbanks, streams and canals – water levels may rise quickly.
- Keep children and pets away from waterways and flooded areas.
- Don’t try to walk, cycle or drive through flooded areas – turn back and use another route.
- Remember: As little as 150mm of fast-flowing water can knock you off your feet and 300mm of fast-flowing water can move most cars off the road.
- Coastal areas may experience wave overtopping, storm surge, and tidal flooding, especially in low-lying locations.
- Keep away from coastal edges, harbours, piers and low-lying promenades during high tide. The Irish Coast Guard advice remains: “Stay Back, Stay High, Stay Dry.”
- Keep a small amount of food, medical and water supplies in case it’s dangerous to step out of the home.
- “Be Winter Ready”: Follow recommendations before, during and after the event on gov.ie – Be Winter Ready (www.gov.ie)
NOTE THAT: The warnings are likely to be updated. Please keep in touch with Met Éireann’s social media channels, www.met.ie and the Met Éireann app to stay up to date with the forecast and any warnings’ updates.
The timing and location of extreme weather occurrences can significantly affect their impact. It’s important to note that in any individual weather event, not every location within a warning area may experience the same degree of weather or impacts.
When severe weather is expected, weather and impacts at lower levels are also likely to be experienced. The type and level of impacts can be strongly affected by previous weather conditions. When issuing a warning, Met Éireann takes into consideration the forecasted conditions and thresholds, as well as previous weather conditions that may increase the level of impact expected for particular areas.

Nuashonraithe Dé Máirt, an 9 Nollaig 2025, i bhfeidhm go dtí go bhfógrófar a mhalairt.
Beidh gaotha láidre agus báisteach throm ar fud na hÉireann ó oíche Dé Luain, an 8 Nollaig, agus i rith Dé Máirt, an 9 Nollaig, mar gheall ar chóras lagbhrú, ar thug Met Éireann an t-ainm Stoirm Bram air.
Tá Met Éireann ag déanamh monatóireacht ar chóras Atlantaigh atá ag forbairt agus a gceaptar go mbeidh gaotha láidre, leibhéil arda uisce feadh an chósta, agus tréimhsí de bháisteach throm dá bharr ar fud na hÉireann ó go déanach oíche Dé Luain (an 8 Nollaig) agus i rith Dé Máirt (an 9 Nollaig).
Tar éis seachtain de bháisteach leanúnach, tá na hithreacha ar fud na tíre an-sáithithe cheana féin agus tá go leor aibhneacha ag druidim le leibhéal lán a mbruach. Dá bhrí sin, is dócha go mbeidh tuilte dromchla agus tuilte abhann mar thoradh ar aon bháisteach bhreise ar an Máirt agus, b’fhéidir, sna laethanta ina dhiaidh sin.
CÉN FÁTH AR AINMNÍODH Í?
Tá Met Éireann ag déanamh faireacháin ar an gcóras seo le roinnt laethanta anuas. Cé gur córas neamhsheasmhach é agus nár fhorbair sé go hiomlán tráth a ainmniúcháin, is léir go mbeidh tionchair chomhcheangailte aige i roinnt contaetha i rith an lae, Dé Máirt, an 9 Nollaig, de bharr idirghníomhú na ngaoth láidir, na báistí agus na lánmhara comhthráthacha. Ainmníodh an stoirm mar gheall ar éifeacht na ngaoth láidir ar limistéir chósta ag am lán mara, chomh maith leis an mbáisteach throm a thitfidh ar ithreacha atá sáithithe cheana féin, rud a mhéadóidh an baol tuilte.
Deir an meitéareolaí Matthew Martin:
“Tá sé ag éirí níos dóichí anois go mbeidh aimsir an-gharbh ag Éirinn ó oíche Dé Luain agus i rith Dé Máirt. Rachaidh córas lagbhrú san Atlantach i ndianú go measartha tapa agus é ag druidim leis an gcósta thiar theas oíche Dé Luain. Ar dtús beidh tréimhse de bháisteach throm ann sula bhforbróidh limistéar de ghaotha an-láidre. Tá éiginnteacht fós ann maidir le rian agus déine an chórais, ach is dócha go mbeidh tionchar suntasach aige i gceantair áirithe, go háirithe i limistéir chósta an deiscirt, an iarthair agus an iarthuaiscirt.
Mar gheall ar nádúr athraitheach an chórais, tá rabhadh gaoithe buí eisithe againn don tír ar fad, agus ina dhiaidh sin sraith rabhadh gaoithe oráiste do chontaetha cósta an deiscirt agus an iarthair, ós iad sin is leochailí i leith thionchair chomhcheangailte na gaoithe ag am lán mara. Tá rabhadh báistí buí eisithe againn freisin do Cheatharlach, Chill Chainnigh, Loch Garman, Corcaigh, Ciarraí, Tiobraid Árann agus Port Láirge. Molaimid, áfach, do gach duine súil ghéar a choinneáil ar réamhaisnéisí agus rabhaidh Met Éireann, mar is dócha go n-athróidh an scéal de réir mar a bheidh níos mó cinnteachta ann faoi rian agus am an chórais.”
Lean Matthew air:
“Táthar ag súil le tionchair tuilte mar go dtitfidh an bháisteach ar ithreacha atá sáithithe cheana féin agus go bhfuil go leor aibhneacha ag druidim le leibhéal lán a mbruach faoi láthair. Táimid i dtréimhse lán mara réalteolaíoch, a bheidh ag teacht leis na gaotha láidre, a bheidh ag séideadh isteach ón bhfarraige i gceantair áirithe, agus dá bhrí sin tá baol ard tuilte cósta ann. Aithnímid agus athdhearbhaímid an seanchomhairle aitheanta ó Gharda Cósta na hÉireann: “Fan Siar, Fan Ard, Fan Tirim”.
Cuirfidh an lánmhara cosc ar aibhneacha draenáil amach chun na farraige, rud a mhéadóidh go suntasach an baol tuilte suas an abhainn i limistéir ísle. Ba cheart don phobal aird a thabhairt ar threoir a n-údarás áitiúil agus na seirbhísí éigeandála ina gceantar.”
AN SCÉAL MEITÉAREOLAÍOCH
Tá sé tuartha go rachaidh lagbhrú Atlantaigh atá ag dul i ndianú gar d’Éirinn oíche Dé Luain agus Dé Máirt.
Neartóidh gaotha an deiscirt chun tosaigh ar an gcóras oíche Dé Luain, agus d’fhéadfadh séideáin ghaoithe an-láidre tarlú, go háirithe feadh chóstaí sceirdiúla an Atlantaigh. Leanfaidh na gaotha láidre ar aghaidh i rith Dé Máirt, ag casadh ó dheas go dtí an t-iardheisceart agus ansin siar de réir mar a théann an lá ar aghaidh. Titfidh báisteach throm go déanach Dé Luain go maidin Dé Máirt ar ithreacha atá báite in uisce cheana féin, rud a mhéadóidh an rith chun srutha agus a chuirfidh dlús leis an tionchar atá ag aibhneacha.
Tá leibhéal measartha muiníne fós ann maidir le rian agus déine bheacht an chórais; d’fhéadfadh athruithe beaga ar a chonair tionchar suntasach a imirt ar dhéine na n-iarmhairtí. D’fhéadfadh athrú beag ar chonair an chórais tionchar a imirt ar na séideáin ghaoithe is láidre, ar uainiú na ngaoth is treise agus ar mhéid na dtionchar cósta. Leanfaidh Met Éireann de dhianfhaireachán a dhéanamh ar an gcóras agus nuashonróidh sé na rabhaidh de réir mar is gá.

RABHAIDH AGUS TIONCHAIR:
Braithfidh déine na ngaoth agus a dtionchair ar an idirghníomhú idir an t-ísealbhrú agus an scairdsruth. Mar threoir maidir leis na tionchair fhéideartha, tá na rabhaidh seo a leanas eisithe ag Met Éireann (amhail an 7 Nollaig tráth foilsithe):
Foláireamh Báistí Buí do chontaetha an deiscirt, áit a bhfuiltear ag súil go dtitfidh báisteach throm ar ithreacha atá sáithithe cheana féin, agus go bhfuil go leor aibhneacha sa deisceart ag druidim le leibhéal lán a mbruach tar éis seachtain de bháisteach leanúnach.
I measc na dtionchar a bhfuiltear ag súil leo i rith Dé Máirt (fiú má théann an rabhadh báistí in éag maidin Dé Máirt) tá:
Foláireamh Gaoithe Buí don tír ar fad i rith Dé Máirt, agus Foláireamh Gaoithe Oráiste do chontaetha éagsúla ag amanna éagsúla i rith an lae, mar gheall ar ghaotha an-láidre go gaotha de neart stoirme ón deisceart, agus na gaotha is láidre feadh an chósta.
Áirítear ar na Tionchair Fhéideartha iad seo a leanas:

WHY AND HOW ARE STORMS NAMED?
Storms are named when they could cause ‘medium’ or ‘high’ impacts in one of the three partner countries. This enables consistent, authoritative messaging to the public and other stakeholders to help them to prepare for and stay safe during potentially severe weather events.
Since 2015, Met Éireann and the UK Met Office have been working together on the naming programme and were joined by the Netherlands’ KNMI in 2019, to form the ‘western group’ of European weather services.
When a storm is forecast, the national weather service that expects the biggest impact from the severe weather to hit its region, or is likely to be first affected by it, names the storm. Storm naming happens in conjunction with orange/red weather warnings, which could be for wind, rain or snow, or a combination of these conditions. Those warnings are, in turn, issued based on a combination of numerical thresholds and the potential impacts foreseen.
CONAS A ROGHNAÍTEAR AINMNEACHA STOIRMEACHA?
Don séasúr 2025/26, chuir gach ceann de na trí sheirbhís meitéareolaíochta seacht n-ainm leis an liosta séasúir. D’iarr Met Éireann ar mhuintir na hÉireann a rogha ainmneacha a chur isteach trí fheachtas ar na meáin shóisialta. Fuarthas níos mó ná 10,000 ainm ó 4,137 duine den phobal.
Is iad seo a leanas an liosta iomlán do shéasúr 2025/26: Amy, Bram, Chandra, Dave, Eddie, Fionnuala, Gerard, Hannah, Isla, Janna, Kasia, Lilith, Marty, Nico, Oscar, Patrick, Ruby, Stevie, Tadhg, Violet, Wubbo.

PAST STORM SEASONS OVERVIEW

Issued on 7th December 2025, valid until further notice
A deepening Atlantic low-pressure system will impact Ireland on the night of Monday 8th December and during Tuesday 9th.
Met Éireann is closely monitoring a developing Atlantic system with the potential to bring very strong winds, high coastal water levels, and periods of heavy rainfall to Ireland from late Monday night (8th December) through Tuesday (9th December).
After a week of persistent rain, soils across the country are already highly saturated and many rivers are approaching bank-full conditions, so any additional rainfall is likely to result in surface and river flooding on Tuesday and possibly during following days.
Meteorologist Matthew Martin, says:
“It’s looking increasing likely that Ireland will experience some very inclement weather from Monday night and through Tuesday. A low-pressure system in the Atlantic is going to deepen fairly rapidly as it approaches the country on Monday night. Initially there will be a spell of heavy rain before a swathe of very strong winds develop. There remains a good deal of uncertainty in the track and intensity of the system, but it has the potential to be an impactful event. Given its evolving nature, we have issued a yellow wind warning for the entire country which will be updated when certainty increases, as well as yellow rainfall warnings for certain areas, and we encourage everyone to check in regularly with Met Éireann’s forecasts and warnings.
Flooding impacts are expected as the rain will fall on already saturated ground and many rivers are currently approaching bank full conditions. We are in a period of high astronomical tides, which will coincide with the strong, potentially onshore winds, so coastal flooding is likely. We echo the well-known advice of the Irish Coast Guard: “Stay Back, Stay High, Stay Dry”.
The high tides will prevent the rivers from discharging to the sea, significantly increasing the risk of upstream flooding along low-lying areas. People should refer to the guidance of their local authorities and emergency responders in their area.”
METEOROLOGICAL SITUATION
A deepening Atlantic depression is forecast to track close to Ireland on Monday night and Tuesday.
Southerly winds ahead of the system will strengthen on Monday night, with periods of severe wind gusts possible, especially near exposed Atlantic coasts. The strong winds will continue through Tuesday, veering southwest to west in direction during the day. Heavy rainfall late Monday into Tuesday morning will fall over ground that is already water-logged, increasing runoff and river response times.
The system hasn’t developed yet (as of Sunday afternoon). Confidence remains moderate regarding the exact track and intensity of the system; small shifts will influence the severity of impacts. A slight shift in the system’s path could influence peak wind gusts, timing of strongest winds, and the extent of coastal impacts. Met Éireann will continue to monitor the system closely and update warnings as required.

WARNINGS AND IMPACTS:
The intensity of the winds and their impacts will depend on the interaction of the low with the jet stream, but as a mean for awareness of the potential impacts, Met Éireann has issued the following warnings (on 7th December at time of publication):
A Status Yellow rain warning across southern counties, with heavy rain expected to fall on already saturated ground and with many rivers in southern regions approaching bank full conditions after a week of steady rain.
Expected impacts, throughout Tuesday (even if the rain warning will expire on Tuesday morning) are:
• Surface and river flooding, through the whole day Tuesday, even if the rain warning will expire on Tuesday morning, as the rivers may take time to respond. Coinciding high tides will prevent river water from discharging to the sea, causing water to back up and significantly increasing the risk of upstream flooding along low-lying areas, especially across rivers in Cork, south Kerry, south Tipperary and Waterford.
• Difficult travel conditions
• Potential disruption to outdoor events.
A Status Yellow wind warning for Ireland all day Tuesday, due to very strong and gusty southerly winds expected, and the possibility of gales near coastal areas.
Expected impacts include:
• Difficult travel conditions: Surface water, reduced visibility, and strong winds may make driving hazardous and could lead to delays on roads, rail, and ferry services. Allow extra time and take caution on exposed routes.
• Flooding in low-lying coastal areas: The combination of the southerly, onshore winds with very high astronomical tides and wave action will heighten the risk of coastal flooding. Surge levels will rise to 0.8m in some locations and significant waves are forecast. Coastal flooding is likely, particularly during high tide times and in exposed low-lying areas. High tide on western and southern coasts is early Tuesday morning (7-9am), whilst time of high tide is close to 2pm on eastern coasts. “Stay Back, Stay High, Stay Dry”.
• Wave overtopping: Large waves may breach sea walls or coastal barriers, posing risks to people near shorelines and potentially impacting coastal infrastructure in exposed locations.
• Debris and loose objects displaced: Strong winds could lift unsecured items, increasing the risk of minor damage or hazards on roads and in public spaces.
• Outdoor events impacted: Weather conditions may lead to delays, cancellations, or the need for additional safety measures for outdoor activities.
The warnings may be updated as new model runs are analysed and certainty increases. For all warnings details, please check Warnings & Advisories – Met Éireann – The Irish Meteorological Service
HOW TO STAY SAFE IN SEVERE WEATHER – BE WINTER READY
Stay informed & plan ahead:
Stay up-to date with the forecast and the warnings for your county on met.ie, the Met Éireann app or Met Éireann socials (@meteireann).
Be aware of elevated flood risk and high winds:
NOTE THAT: The warnings are likely to be updated. Please keep in touch with Met Éireann’s social media channels, www.met.ie and the Met Éireann app to stay up to date with the forecast and any warnings’ updates.
The timing and location of extreme weather occurrences can significantly affect their impact. It’s important to note that in any individual weather event, not every location within a warning area may experience the same degree of weather or impacts.
When severe weather is expected, weather and impacts at lower levels are also likely to be experienced. The type and level of impacts can be strongly affected by previous weather conditions. When issuing a warning, Met Éireann takes into consideration the forecasted conditions and thresholds, as well as previous weather conditions that may increase the level of impact expected for particular areas.
