Dublin is on alert as Storm Brendan brings strong winds and a risk of flooding.
Damaging gusts of up to 130 kilometres an hour are expected across the country.
An orange alert is in place for Connacht, Donegal and Kerry, that will last until 9pm. While Dublin and the rest of the country is under the warning until 3pm today.
Met Éireann says there is a significant risk of coastal flooding "due to the combination of high spring tides and storm surge."

Dublin City Council is putting up flood defences and has closed the car parks at Clontarf and Sandymount.
Flood gates may also be closed along the River Dodder near Ballsbridge.
Fingal county council says sandbags are available for collection from its Watery Lane Depot in Swords. High tide is expected at 1pm.
The local authority says flooding is expected in coastal areas with the highest threat in Sutton, Baldoyle, Portmarnock, Malahide, Portrane, Rush, Skerries and Balbriggan.
