“Huge uncertainty” surrounds the potential arrival of stormy weather in Ireland this coming weekend as wind and heavy rain look set to dominate in the coming days.
Alan O’Reilly of Carlow Weather said in an update on Tuesday morning that there is still no consensus among the various weather models about exactly how bad it will get heading into the weekend, but there is agreement that it will be windy and it will be wet.
The model showing the “worst possible outcome”, the ECMWF (European Centre for Medium-Range Weather Forecasts) model, indicates that there could be gusts approaching 200 km/h in the west of Ireland on Friday, a day when Met Éireann has forecast widespread heavy rain and “strong and gusty southerly winds”.

Before that, up to 100mm of rain is expected to fall on Thursday ahead of another deluge on Friday; again, the west of Ireland is expected to be worst affected by the inclement weather headed our way.
Ireland has not had any named storms since the new storm season started on September 1 and should there be cause to name one this weekend, it will be called Amy.

O’Reilly said, however, that some weather models show the worst of the weather avoiding Ireland and that weather apps are likely to show big changes in the coming days.
Met Éireann, for its part, has forecast conditions will become “rather unsettled as we move through the week”.
“Rain will become more widespread with breezy or windy conditions developing too,” the latest forecast reads, with the weather set to become gradually worse on Thursday and Friday ahead of a windy weekend that should at least be drier than the washout expected on those two days.
Check out the Met Éireann forecast for the coming days in full below.
Tuesday
Today will be dull and misty with hill fog. There will be scattered outbreaks of rain and drizzle during the morning and early afternoon, then more persistent rain will spread across the country from the west during the late afternoon and evening. Highest temperatures of 14 to 18 degrees with light to moderate southerly winds, freshening in the west during the afternoon.
Cloudy with mist and hill fog on Tuesday night. Wet at first with widespread rain but the rain will move northwards, becoming lighter and patchier by morning. Lowest temperatures won’t fall below 13 to 15 degrees, in a moderate to fresh southerly breeze.
Wednesday
Rather cloudy tomorrow but dry for most with scattered outbreaks of rain, most frequent in the west and north. Some brighter intervals possible, most likely towards the east. Highest temperatures of 15 to 18 or 19 degrees with a moderate to fresh southerly breeze.
Continuing cloudy with scattered outbreaks of rain spreading eastwards across the country on Wednesday night. Mild with temperatures not falling below 13 to 15 degrees, in a moderate to fresh southerly breeze.
Thursday
A rather wet and breezy day with widespread persistent rain, heaviest in the southwest and west. Highest temperatures of 14 to 16 degrees with a fresh southerly wind. Rain will clear eastwards early on Thursday night and it’ll become mainly dry with clear spells for a time.
However, more cloud will extend across the country from the southwest later in the night, bringing rain to the west and southwest by morning. Lowest temperatures of 9 to 12 degrees with light to moderate west to southwest winds, becoming southerly.
Friday
Current indications suggest Friday will be a wet and windy day with widespread rain, heavy at times, accompanied by strong and gusty southerly winds. Highest temperatures of 16 to 18 degrees.
The weekend
It will continue breezy while turning cooler but generally drier for the weekend, although some showers are likely, especially in the north and west.
