Met Éireann issues update on timeline and potential flood warnings ahead of Storm Dennis

Storm Dennis is to stick around until early next week.

The national weather service have already issued a weather advisory ahead of the arrival of Storm Dennis, as well as the first of what they have confirmed will be several weather warnings over the weekend, but they've got even more information to share ahead of the weekend.


As part of their Meteorologist's Commentary issued today (Friday 14 February), Met Éireann stated the following:

"Storm Dennis (as named by the UK Met Office), is currently undergoing rapid cyclogenesis in the Western Atlantic. While staying to the northwest of Ireland Storm Dennis will produce some wet and windy weather over Ireland this weekend."

Essentially there are some strong warm winds and strong cold winds battling it out over the Atlantic, much closer to Iceland than to Ireland, but we will be near enough to feel it.

This is how they predict the weekend to play out:

Saturday - The first round of wet and windy weather will reach the Atlantic coast on Saturday morning spreading countrywide during the morning easing later and Status Yellow wind and rain warnings are in operation.

Sunday - The core of Storm Dennis will gradually fill and weaken as it tracks south-eastward towards Ireland bringing squally showers with a risk of thunder. A widespread Status Yellow wind warning is likely to be issued and possibly Orange level winds locally (especially in the vicinity of squally showers along Atlantic coasts) can be expected.

Monday - Winds will gradually ease through Monday, but not dissimilar to this past Monday showery conditions can be expected with wintry conditions possible.


Additionally, they have warned of potential flooding issues, with high rainfall likely to cause rivers across the country, particularly in the midlands, the south, and the west of the country to break their banks. Also, the combination of high winds and high sea levels may result in coastal flooding along the west and the south of the country.
