Wet and Windy Week Ahead for Cork as Forecasters Watch Potential Storm on Thursday and Friday

Cork faces an unsettled week, with heavy rain at times on Tuesday and a potentially stormy spell from Thursday afternoon into Friday. Confidence in the strength of the peak gusts is low, as the track of the area of low pressure remains uncertain.

Monday and Tuesday

Met Éireann’s Munster forecast says Monday will be a bright and chilly start, with frost and fog clearing. Cloud will increase during the morning and some patchy outbreaks of rain and drizzle will develop, with highs of 11 to 13 degrees in mostly light easterly winds.

There will be further outbreaks of rain and drizzle on Monday night, but many parts will stay dry. It will become cloudier overnight, with rain moving into the southwest towards morning and lows of 3 to 7 degrees in light to moderate winds.

Rain will affect much of the province during the morning and afternoon on Tuesday before it spreads eastwards, and it will be heavy at times. Scattered showers will follow, with moderate to fresh southeasterly winds at first becoming westerly later in the day. Highs will be 9 to 12 degrees.

Met Éireann’s national outlook says the rain will spread eastwards across the country on Tuesday night, heavy at times. It will be windy too, with moderate and at times fresh westerly winds. The rain will start to clear from the west in the morning, with scattered showers following and lows of 5 to 9 degrees.

Cathal Nolan of Ireland’s Weather Channel said that in some of the weather models, there is the possibility of stronger winds on the back end of Tuesday’s system, with a risk of gusts up to 100 km/h, even a little more in places.

Cork Safety Alerts’ analysis of the ECMWF and GFS model charts for Cork City, based on approximate chart interpretations, suggests gusts potentially reaching 60 to 80 km/h late on Tuesday evening. Gusts of around 70 to 95 km/h are possible on exposed approaches to the city overnight into Wednesday morning.

Wednesday

The rain will linger in the east for a time during Wednesday afternoon, with sunshine and scattered showers for the rest of the country. Met Éireann says it will be a blustery day with moderate to fresh westerly winds and highs of 8 to 12 degrees.

Showers will continue along the west coast on Wednesday night, but it will be largely dry elsewhere, with lows of 3 to 7 degrees.

Thursday into Friday

There will be some showers at first on Thursday morning, but rain will then arrive in the southwest during the afternoon. Met Éireann says heavy falls are likely as it spreads to all parts during the rest of the day, with highs of 10 to 13 degrees.

Met Éireann’s outlook adds: “At the moment, it looks like being very windy with strong and gusty northwesterly winds.”

The rain will gradually spread to the east on Thursday night and clear away to the east overnight, with lows of 5 to 8 degrees. Friday will bring scattered showers and blustery winds, with highs of 8 to 11 degrees.

Mr Nolan said Ireland’s Weather Channel is still trying to determine the low’s exact track, depth and intensity. He said it still looks as though it will skirt along the south coast and may enter the UK around Fishguard in South Wales. He added that it is likely to bring potentially storm-force winds, perhaps even violent storm-force winds, to parts of South Wales, Devon and Cornwall in particular, and along the south coast of England.

Cathal Nolan, Ireland’s Weather Channel:

“For ourselves, it looks like it is going to be mostly a rainfall event that we have to contend with.”

He said that in some of the higher-resolution models, rainfall totals of 50 to 70 mm cannot be ruled out, and over higher ground, those totals could even be a little bit higher. He said it is quite an active system, and with very warm sea surface temperatures at the moment, it is whisking up a lot of moisture.

Cathal Nolan, Ireland’s Weather Channel:

“So we are expecting some significant weather warnings into parts of the southern half of the country in particular as we go into Thursday and Friday, possibly Status Orange rainfall warnings more so likely.”

He added that some Status Yellow wind warnings are also possible, with strong north to north-westerly winds on the back end of the system.

Mr Nolan said there is probably a 60 per cent chance the low takes the southerly route, staying just off the south coast of Ireland and entering parts of South Wales. He put the chance of it moving a little further north and having a more significant impact on Ireland at maybe 20 per cent. He said a track well to the south is the least likely option.

Cathal Nolan, Ireland’s Weather Channel:

“The main focus, I think, for stormy conditions is likely to be down across South Wales, Devon, and Cornwall at the moment, but it does not take a lot to change the exact track of that storm depression.”

He said he thinks it is likely to become the first named storm of the year, perhaps named by the UK Met Office for the storm-force winds the UK could see. He said it would be named Storm Austin if that is the case.

What the Charts Show for Cork City

Cork Safety Alerts’ chart analysis points to Thursday evening into Friday morning as Cork City’s main storm risk, with GFS showing a substantially stronger wind event than ECMWF. All figures are approximate chart interpretations.

Rain is provisionally expected to arrive between 13:00 and 17:00 on Thursday. Rates could reach 2 to 5 mm an hour in heavier spells, creating standing water and poor visibility.

The principal deterioration comes on Thursday evening and could continue beyond midnight, with roughly 15 to 30 mm for the main rain spell through early Friday. ECMWF suggests gusts of around 70 to 90 km/h, while GFS allows approximately 100 to 110 km/h near Cork.

Overnight into Friday morning is potentially the most disruptive wind period, particularly before dawn. Winds turn west to northwest, with gusts provisionally 70 to 110 km/h during the peak. Debris, standing water and spray could affect visibility and travel.

Friday afternoon is expected to remain showery and windy, with gradual improvement in the evening, although exposed routes could remain gusty initially. Confidence in peak gusts is low because the low’s track remains unsettled. Confidence for Friday evening is low to medium, especially in how quickly the winds ease.

Anyone travelling should allow extra time from Thursday afternoon through Friday, avoid flooded roads, and check updated forecasts before using exposed routes. Any weather warnings will be published on Met Éireann’s warnings page.

The Weekend

Met Éireann says it looks like it will remain unsettled over the weekend, with more rain and some blustery conditions.
