LAST UPDATE | 27 Aug

MET ÉIREANN HAS upgraded Dublin to a Status Orange rain warning until 3am as a Status Yellow warning remains in place for several other counties.

The warning for counties Carlow, Kilkenny, Wexford, Wicklow, Cork and Waterford came into effect at 12pm today, and Dublin and Kildare were added this evening. The warning was extended until 6am on Friday instead of 3am.

Tonight, the national forecaster warned that spells of very heavy rain in Dublin may cause localised flooding and very difficult travelling conditions.

For counties under a Status Yellow warning, Met Éireann said spells of heavy rain are expected, with a possibility of thunderstorms, which could lead to localised flooding and difficult travelling conditions. 

The forecaster also warned that outdoor events could be impacted. It comes amid a “very mixed” forecast for Stradbally, Co Laois, where tens of thousands of fans are expected to descend upon the town for the festival Electric Picnic.

Kerry County Council has said “significant” flash flooding has occurred in Killarney.

The N22 road at the bottom of Pike Hill is closed, and the fire brigade were to pump out floodwaters, the council said.
