Met Éireann has issued a Status Orange weather warning for counties Cork, Kerry, Limerick, Clare and Galway on Tuesday (7 December) when Storm Barra is forecast to sweep in from the Atlantic.

Southerly winds, later becoming to northwesterly, will reach mean speeds of 65 to 80 km/hr with severe or damaging gusts of up to 130 km/hr. Met Éireann says winds will possibly be higher in coastal areas, and that disruption to power and travel are likely.

“High waves, high tides, heavy rain and storm surge will lead to wave overtopping and a significant possibility of coastal flooding,” the meteorologists warn.

A Status Orange marine warning will also be in effect for 24 hours from midnight tomorrow (Monday 6 December) as southerly winds veering westerly are expected to reach Force 8 to 10 on Irish coastal waters from Mizen Head to Erris Head to Fair Head.

Met Éireann is collaborating with Denmark, Iceland and the Netherlands on a new supercomputer designed to advance short-term weather forecasting.

The new multimillion high-performance computer built by Hewlett Packard Enterprise (HPE) will also be used to advance climate science research as part of preparation for the impacts of climate change, Met Éireann says.

“With global temperatures projected to increase further over the next decades, weather patterns are expected to become more extreme and more challenging to forecast,”it says.

The new supercomputer will be operational by early 2023 under the project name “United Weather Centres-West”.

It will perform 4,000 trillion calculations per second and handle millions of weather observations every 24 hours - producing detailed weather forecasts every hour, which is especially critical ahead of severe weather.

It will be powered entirely by renewable Icelandic hydropower and geothermal energy, meaning running costs and the CO2 footprint will be kept to a minimum.

Met Éireann says it will provide high-resolution weather forecasts that will be used to provide more accurate and timely weather warnings, allowing emergency services to prepare for potential impacts of severe weather;

It will also provide “more timely and focused information” to marine communities, along with the agricultural and transport sectors, in relation to extreme weather events, it says.

The project involving Met Éireann, the Danish Meteorological Institute, the Icelandic Meteorological Office and the Royal Netherlands Meteorological Institute is part of a broader collaboration between ten national weather centres in Europe.

The United Weather Centres group plans to operate a common multi-national weather forecasting system by the end of the decade.

Met Éireann director Eoin Moran said the UWC-West supercomputer is “the first step in a powerful collaboration between weather services in Europe which will allow Ireland to meet the growing challenge of forecasting high impact weather events with much greater confidence”.

“ Our countries have a long history of working together in weather prediction research. Denmark, The Netherlands, Iceland and Ireland bound the North East Atlantic Area and are now combining resources to best predict the weather that impacts this region,”Moran said.

“ This is particularly important in the context of the influence of climate change on the predictably of weather systems as the new supercomputer will allow for the incorporation of the most up to date weather forecasting methodologies,”he said.

A Status Orange weather warning is in place for all Irish coastal waters and the Irish Sea as strong gales are set to develop overnight with the arrival of Storm Aiden, the first of the new storm season.

Met Éireann reports that winds will reach storm force off the South and South West Coasts in the early hours of tomorrow, Saturday 31 October, later veering westerly during the day and reaching gale to storm force on all coastal waters and the Irish Sea.

Tomorrow morning’s winds will reach mean speeds of 65 to 80km/h, with severe and damaging gusts of 100 to 130km/h, affecting Cork, Kerry, Waterford and Wexford as well as Carlow, Kilkenny and Wicklow.

Later in the day these severe winds will veer west over counties Clare, Galway, Mayo, Sligo and Donegal. The rest of Ireland is under Status Yellow with lesser but still potentially damaging gusts forecast, as well as a risk of coastal flooding.

The storm follows the remnants of Hurricane Epsilon, which brought ‘phenomenal’ class seas to the West Coast on Tuesday and Wednesday — just the ticket for the big wave surfing enthusiasts of Mullaghmore Head.

Local surfers told RTÉ News that the swells of earlier this week were some of the biggest they’ve ever seen here, and Conor Maguire was among those up for the challenge.

Met Éireann has issued a Status Red marine warning as Storm Ellen approaches today, Wednesday 19 August.

Gale- to storm-force winds, southeast veering southwest, are forecast for this evening and tonight on all Irish coastal waters and on the Irish Sea.

Winds will even reach violent storm Force 11 for a time on the South and West Coasts from Carnsore Point to Valentia to Slyne Head.

From tonight to early Friday the weather may result in unsafe conditions and disruption especially over high ground, lakes and sea areas.

There is also a risk of flooding from storm surges as heavy rains meet spring tides at their highest.

Cork will bear the brunt of the storm, which will produce a core of very severe and destructive winds between 9pm and midnight tonight.

A Status Red marine weather warning is in place this morning (Saturday 29 February) as Storm Jorge brings southwesterly winds to gale or strong gale force on all Irish coastal waters.

Winds will veer westerly later this morning and this afternoon, increasing from gale force to storm force, and reaching violent storm force for a time between Loop Head and Erris Head.

On land, Met Éireann says the strongest winds will be experienced in Galway and Clare, reaching mean speeds of 85 to 100km/h in places this afternoon with gusts of 130 to 145km/h, and with an elevated rusk of coastal flooding.

“The combination of high seas and strong winds or stormy conditions associated with Storm Jorge may increase the possibility of coastal flooding, especially in flood-prone areas along the Atlantic coast on Saturday (particularly when coincident with high tides),” the meteorological service adds.

A Status Orange wind warning is in place for the rest of the country as severe winds, southwest quickly veering wet and later northwest, will reach mean speeds of 65 to 80km/h with gusts of 110 to 130km/h — possibly higher in very exposed areas — with an elevated coastal flood risk.

Heavy rainfall over this weekend is expected to compound flooding issues with water levels already elevated nationwide, particularly in the northern half and in the Midlands.

Among events schedules for this weekend that have been cancelled is the Lagan Head of the River rowing event, which may be rescheduled for later this year.

A Status Yellow gale warning remains in place for all Irish coastal waters after Storm Atiyah brought high winds across the country yesterday (Sunday 8 December).

Northwesterly gales were expected for a time on waters from Malin Head to Howth Head to Roches Point and on the Irish Sea after the first winter storm of the current season tracked eastwards across the island of Ireland.

In addition, southerly gales or strong gales are forecast to develop tonight on all coastal waters and on the Irish Sea, in the warning posted by Met Éireann in effect from 6am this morning (Monday 9 December).

Earlier yesterday, a Status Red wind warning — the most severe — was issued for Kerry with gusts expected to reach over 130km/h yesterday evening, as RTÉ News reports.

Turkey Shoot sailing was cancelled for Dublin Bay due to the rising winds, as was the scheduled dinghy Frostbites event.

Reports of severe weather damage and other incidents came from around the country, with ESB Networks dealing with numerous power outages, fallen trees and debris on roads and rail lines — and one motorist who left their car too long on the shoreline Co Donegal saw the vehicle swamped by the tide.

“The sea will come and take” Dublin and Cork by 2050 if nothing is done to deal with the consequences of climate change, Gerald Fleming will say in an RTÉ TV documentary tonight as The Irish Times reports.

The former weather presenter and head of forecasting at Met Éireann adds that the port towns of Drogheda, Galway, Limerick, Waterford and Wexford are also particularly vulnerable to rising sea levels, increasingly severe weather, more frequent storm surges and extreme flooding.

Fleming explores the direct effects climate change has already had on the likes of Greenland, while he and researcher Cara Augustenborg will present computer models that show the damage that could be caused to Ireland in the not too distant future.

Will Ireland Survive 2050?, part of RTÉ’s new On Climate season, screens tonight (Monday 11 November) at 9.35pm on RTÉ One. Fleming tells more about the programme at RTE.ie.

Met Éireann says the progress of Hurricane Lorenzo this week and any potential impacts for Ireland “are being closely monitored”.

The powerful weather system, which is currently threatening the Azores in the mid-Atlantic, was recently the most easterly Category 5 hurricane on record, surpassing Hurricane Hugo 30 years ago.

Forecasts beyond the next 48 hours “still of low confidence given the uncertainty” of the storm’s current behaviour.

Numerical prediction models currently show a wide spread of outcomes for the storm track ranging from Greenland to the north of France.

As of today (Monday 30 September) it’s expected that Lorenzo will transition into an “extra-tropical depression” between noon and midnight on Wednesday 2 October.

Met Éireann says its most likely path after this transition brings it to the northwest of Ireland without making landfall.

However, even at that it “still brings the risk of severe winds, possibly stormy conditions and very high seas”, as Met Éireann’s Deirdre Lowe told BreakingNews.ie.

Latest updates will be provided on the Met Éireann website HERE.

The weather warning issued by Met Éireann for Co Clare has been upgraded to the most severe Status Red as Storm Hannah is expect to brings gusts of up to 150km/h this evening (Friday 26 April).

Meanwhile, the marine warning has been upgraded to Status Orange, as cyclonic variable winds will increase to gale Force 8 or strong gale Force 9 on Irish coastal waters from Howth Head to Mizen Head to Rossan Point and on the south Irish Sea during this afternoon and evening.

Winds are forecast to reach storm Force 10 to violent storm Force 11 this evening and early tonight between Carnsore Point and Slyne Head.

The extreme weather has seen the cancellation of sailing and watersport events nationwide, including rowing’s Limerick Regatta which had been scheduled for tomorrow.

#StormFionn - Met Éireann has issued a Status Orange marine weather warning for all coasts of Ireland and on the Irish Sea today (Tuesday 16 January) as Storm Fionn sweeps in.

Westerly gales or strong gales with mean speeds of up to 80km/h and gusts of as much as 120km/h are forecast for all coastal waters, increasing to storm force from Roches Point to Slyne Head to Malin Head later this afternoon, this evening and tonight.

Donegal, Galway, Leitrim, Mayo, Sligo, Clare, Cork and Kerry are under a Status Orange wind warning till late tonight, with much of the rest of the country under Status Yellow for mean wind speeds of between 55 and 65km/h and gusts of around 100km/h expected.

The sixth winter storm of the current season comes two weeks after Storm Eleanor, the brunt of which was felt in Donegal and Northern Ireland.
