LAST UPDATE | 25 Sep 2023

A STATUS YELLOW wind warning is in place for 24 counties on Wednesday, with Met Éireann warning about the potential for flooding and power outages. 

The system has officially been named as Storm Agnes by the UK Met Office, with a number of warnings now put in place in Ireland.

“This developing storm is currently out in the mid-Atlantic. Our latest analysis chart shows the weather system in its infant stage,” said Met Éireann.

“Over the next few hours and days this developing area of low pressure will be taken up by the jet stream and undergo rapid deepening.”

The Status Yellow wind warning applies to Leinster and Munster from 7am on Wednesday for the rest of the day, with the same warning also in place in the six counties in Northern Ireland from 12pm until 7am on Thursday. 

A Status Yellow rain warning is also in place for Carlow, Dublin, Kilkenny, Wexford, Wicklow, Cork, Kerry and Waterford.

Met Éireann has said that weather conditions are set to become “very windy on Wednesday with very strong and gusty southerly winds, veering westerly later on”.

This is to be matched with heavy rain with the potential for coastal flooding, power outages, fallen trees and poor visibility for motorists. 

The forecaster had said earlier that a deep Atlantic depression gathering off the south west coast was tracking “close to or over Ireland”. 

“Storm Agnes is likely to make landfall late Wednesday morning and for now a number of weather warnings have been issued in response. These warnings are likely to be updated as further modelling data becomes available,” the forecaster said.

“Currently, the strongest winds are forecast to impact the south and south-east of the country.” Although this may change as the storm approaches, Met Éireann said.
